Well, here's what I found when I opened up Ludwig's transaxle.
I'm holding the gear selector, which you can see has a plastic ball joint inside it. There is a rod that fits in the ball joint. Attached to the very front end of said rod is the shifter. These plastic ball joints are (in)famous for wearing down, which makes shifting more and more sloppy. Ludwig's was so worn down that I am pretty sure it had so much "slop" in it that it couldn't de-select 2nd gear (and at least one crotchety German VW mechanic agreed with me).
It would've been nice if that were all that I'd seen; the old guy gave me a fresh ball joint (for free), and replacement would've been a snap. Alas, I noticed the cracked piece the screwdriver is pointing to in the picture above. Knowing that it'd be a bad idea to reinstall the transmission with an obviously broken part, I went about seeing what it would take to replace this bearing.
What it takes is complete dis- and re-assembly of the transmission.

Dropping the drivetrain
As a result of the tranmission problems Ludwig incurred during the Death Valley trip, Mitch and I had to remove the drivetrain (engine + transmission) for repairs. VW engines and transmissions are oriented in such a way that it's easiest to remove the engine in order to remove and repair the transmission. As I remember it, this is how the whole event unfurled.
Pictured here is the carbeurator. This is where air goes into the engine to mix with gasoline (which eventually burns up to make Ludwig go). The carbeurator is where the "mixing" happens. It usually sits right on top of the engine and hooks up to the intake manifold. The carbeurator has to be removed because the engine is removed under the bus (instead of being lifted up and out). If the carbeurator weren't removed, it would make the engine much taller, but just in that one spot.
This is the air filter that is normally attached to the top of the carbeurator. An air filter should be clean enough so that when holding it up to light, you can see light through it (according to Mitch). As you can see, Ludwig's was filthy from the Death Valley trip, so he'll get a new one soon.
This is looking down at the engine from inside the body of the van. See the four long pipe looking things? Those are the intake manifolds. That's where the carbeurator is normally attached. There are four white rags plugging the openings. The gas-air mixture travels to the cyclinders via the intake manifolds.
Ok, now we're all done with the top of the engine, for now. Next up, we had to disconnect the transaxle. There's one one each side of the transmission attaching to each wheel. After several stubborn hex head bolts were removed, we covered the end of the CV (Constant Velocity) joint with a plastic bag, and wired it to the frame (using an old coat hanger). The greasy black round area is where it was attached. It is quite possibly the thickest blackest grease I've ever seen in my life. Then we did it again to the other side.
The next task was to remove the bumper. Since the drivetrain is removed under the bus, removing the bumper allows a few more inches of clearance.
Removing this oil filler tube gave us some extra clearance too.
Somewhere along the way (actually, it was at the beginning, starting with the battery), Mitch disconnected a bunch of wires, the fuel line, removed the engine seal and we both removed several other bolts attaching the engine and transaxle to the bus. As soon as everything was disconnected, Ludwig was jacked up and resting on jackstands and while the drivetrain was lowered on a different jack, Mitch had an epiphany. He realized why the exhaust should be removed when dropping an engine. The exhaust is quite protrusive, and really got in the way of maneuvering the engine. (The picture above shows how the muffler just sort of protrudes out.) We had come to far to turn back, so we just managed our best. (I didn't want to remove the exhaust unless we really had to, since it is a tremendous pain. We got it out with the exhaust attached, but I see now why one really should take it off.)
After a few minutes of head scratching, raising and lowering the jack and pushing and pulling the engine, Ludwig's drivetrain came right out.
The engine is what's mainly on the jack above. The more narrow hunk of metal on the front, just under Ludwig's tail, is the transmission. Although it looks as though the transmission is resting on the ground in the pictures, rest assured that it is not.
How heavy is Ludwig's drivetrain? Well, I was able to pull it into the garage with the jack completely unassisted, so it wasn't SO heavy.
And now my dear Ludwig waits, but we'll try not to keep him waiting too long.
Somewhere during the beginning of this event, Mitch was describing the process of engine removal to me with analogies, to help me better understand what was going to happen. He explained that removing an engine in most cars is like a moth emerging from a cocoon. Removing an engine from an air-cooled Volkswagen, or "dropping an engine" (because the engine is removed underneath), is more like the VW is giving birth. I just thought I'd share that.
(She skipped a few minor steps, but that's basically how it went.)

The Origin of Ludwig
Ludwig is a 1974 Volkswagen Campmobile, which means VW built most of him and another German company, Westfalia, outfitted him to be a camper (kind of like what Winnebago does to Chevys and Fords in this country). He was built in October of 1973 and left the VW factory in Hanover "Western" Germany on the 24th, which fell on a Wednesday that year. We take this to be a good omen, as Wednesday cars are reputed to be of the best construction.
After some research we believe Ludwig was shipped to San Diego (or possibly San Francisco), probably to be sold at a dealership somewhere in the American southwest. We think he must have spent a great deal of his early life in that part of the country because he is not nearly as rusty as are many, or most VWs of his style and vintage. If he had spent many of his early winters plowing through midwest snow and, worse yet, plying salted roads, he would be in much worse shape than he is today. In fact we were told by a lifelong southern California VW mechanic that he is a pretty nice example, even by SoCal standards. (But don't get us wrong--Ludwig is by no means rust-free. Yet.)After fifteen or so years of now-lost adventures, Ludwig ended up in Nebraska. He spent enough time at Ecco Motors in Bellevue to be tagged with a dealer sticker there, which he retains. At some point in the late 80s or early 90s, he became a resident of Norfolk, Nebraska.
In the spring of 1991, Mitch's friend McDonald, looking for a VW bus of some sort, discovered that Ludwig was for sale with an asking price of $650. In May of that year, McDonald decided to buy him, and he and Mitch went to complete the purchase. The plan did not go off without a hitch. First, McDonald misunderstood that the price was $650 and had only brought $600. The price was firm, so Mitch extended McDonald the extra capital. Second, the true owner was unavailable to sign over the title, so his wife (a notary public, no less) forged his signature there and on the bill of sale. Lastly, as McDonald did not trust Mitch to drive his mother's car home, he insisted that Mitch would helm the VW. To his great embarassment, Mitch could not manage to find the gears in proper sequence or with any skill, and had to drive the McDonald mother's car back to Stanton. During the time Ludwig was McDonald's, Mitch didn't drive him once.
Under McDonald's ownership Ludwig (though he wasn't known as Ludwig then) had a part in many of the expected teenage (mis)adventures. On the several occasions when McDonald was thrown out of the house, being perfectly suited to such service, Ludwig acted as his home-away-from-home. He was the site of not a little partying but save for one cigarette burn on a seat, his interior did not noticeably suffer.
One cold winter day in 1991, years before Mitch and Melissa were to meet, McDonald and Mitch were driving the bus to a trailer court north of Norfolk, Nebraska on Highway 81 to check out a VW Beetle McDonald was thinking about buying. Standing near the highway towered a billboard for the new Bud Dry beer, a picture of a Bud Dry bottle layed on its side with the text "Try Bud Dry" written sideways next to the image. Like a couple of dorks, they both tilted their heads 90 degrees in order to read it. Upon straightening their necks, they noticed that the forward motion of the bus didn't match the centerline of the vehicle--they were sliding a bit sideways. Mitch helplessly watched McDonald try to compensate, turning the oversized horizontal steering wheel for all it was worth (remember: no power steering!). The bus slid back the other direction, and directly into the lane of oncoming traffic. After slipping back and forth across the lanes a couple more times, the bus turned sideways with the passenger-side leading and slid off the opposite shoulder. As the bus slowed down it felt as though it might just slowly come to a halt, but instead it kind of stopped and fell over at the same time. Mitch looked up to see McDonald clutching the door pull in an attempt to keep from falling on top of him; neither of them were wearing seatbelts. They climbed up out of the bus through the driver's side door and surveyed the scene. They'd nearly clipped a road sign, not to mention oncoming traffic. Some guy from Minnesota who'd watched the whole event pulled up to see if they were alright. He gave them a ride to McDonald's Grandpa's house where they tried to hire a towtruck, a difficult and time-consuming ordeal given that it was early Sunday evening. About three hours of phone calls later, they finally pulled up to the scene of the accident in the towtruck, but the vehicle had vanished. The impressions from the tipped bus were clearly marked in the snow, but the bright orange Volkswagen was nowhere to be seen. McDonald called the Pierce county sheriff (they were about 200 yards within the Pierce county line) and was immediately read the riot act for leaving the scene of an accident. Apparently the local police department, fire deptartment and even an ambulance had arrived at the scene not long after they'd gone for help. Since no people were found at the scene the camper was impounded. McDonald had to wait an entire week before he could get it out of hock. The only evidence of the crime was a fresh crease on the sliding door and some minor scrapes, but otherwise it was fine. McDonald noticed it ran better than ever when he drove it away, speculating that lying sideways had allowed gasoline to soak and clean the cylinder walls.
A few months later, now freshman in college, McDonald and his then-girlfriend were driving the bus near 27th and Cornhusker in Lincoln, Nebraska when the engine gave out. The bus was towed over 100 miles to our friend Mark's farm, and put in a big metal barn to wait. Lacking some combination of money, time, and desire to repair it, the old bus just sat in that barn for over ten years, from circa August 1993 until March 2004.
Sometime during the early 2000s, McDonald commented that anyone who put a new engine in the bus could have it. A few people had considered investing their effort into it, but nothing ever came of it. Sometimes, while Mitch helped moved equipment or one of the other cars that were in the barn nearby, he would glance its way and give it another thought. It always stayed in the back of his head that the bus was there, waiting.
During the weekend of Mark's wedding in October 2003, Mitch took Melissa out to Mark's farm to show her where he'd spent so many late nights and weekends, and had so many adventures (especially with old Volkswagens). Since she'd never seen the camper (but had heard plenty of stories), he took her up to the barn to see it, and told her about McDonald's deal. In spite of all the dust and the almost overpowering stench of mouse urine that permeated it, Mitch could see that Melissa kind of fell in love with it then and there. Before we'd left the farm she made him vow that we could (and would) get that camper. In short order, Mitch kept his promise, the deal was struck with McDonald (Mitch insisted on paying McDonald for it despite his admonitions) and Mitch began work on Ludwig in March of 2004.
Mice had destroyed much of the interior, not by chewing it, but with the sheer volume and pugency of their urine. Mouse-piss had eroded away the canvas poptop, part of the upper bunk matress, and most of the carpeting. During strip down and cleaning, Mitch threw away no fewer than five mouse carcasses. (The mice had rendered their environment unlivable; there was no evidence that any had actually lived in the bus for a number of years.) Luckily, they had not only left the wiring untouched (mice often chew on car wires), but also had ignored the extremely hard-to-find and expensive seats and seat padding.
With help from Mark, McDonald, Groaner, and (eventually) a couple VW mechanics, the bus was fitted with a fresh 1800cc engine with a single Weber carb. We also redid the brakes. With much help from Melissa's parents, we redid the interior; new canvas top, carpeting leftover from a living room renovation, and (with Much Help from Melissa's Dad) refurbishing the pee-soaked cabinetry.
We loaded Ludwig (he was Ludwig by now) with various odds and ends and two bikes on a bikerack off the tail, and moved to California just days after getting him road-ready in late July 2004. Like dumbasses, we didn't think twice about driving 1700-plus miles on tires that had been partially or totally flat for more than a decade; they performed admirably, but we lost the front driver's tire on I-15 just west of Mesquite, Nevada, and the front passenger's tire--in fast-moving traffic--on the San Bernardino Freeway just north of Los Angeles. (The rear tires never gave any indication of trouble, and remained on the vehicle until winter 2005.)
Melissa first VW was Ludwig, and Gertrude is her second.
Ludwig and Gertie are Mitch's sixth and seventh VWs, respectively.
Prior VWs in Mitch's possession:
1973 Type III Fastback "Gretchen", d. 1991, contact (1990 Chrysler)
1970 Type III Squareback "Anne", d. 1996, mechanical (engine)
1967 Type III Squareback "Freida", d. 1997, contact (wildlife)
1971 Beetle (Type I) "Margaret", d. 2000, mechanical (engine)
1984 Rabbit "Loretta", d. 2002, mechanical (driveshaft)
M Codes
I think the "M" stands for "manufacturing". For a long time (and up to present day for all I know) every Type 2 had a plate rivetted to it and this plate is covered with a bunch of letters and numbers. It encoded information about the vehicle's final configuration so it got the proper equipment as it moved down the assembly line. Some ACVW freaks have gone to great lengths figuring out what information the codes encode. It is kind of interesting. Here are Ludwig's M Codes, decoded:
42 050 077
227 507
922690 D55 P22 O27
43 3 7685 UF 2319 41
4=1974 model year. 2=bus. 050 077=50,077th built that model year (out of 224,993 total).
227=detachable headrests. 507=vent wings in doors.
9226="brilliant orange" paint. 90=cloth interior. D55=US specifications. P22=Westfalia interior set up. O27=emissions compliant
43=built in the 43rd week of 1973... 3=...on a Wednesday. 7685=unknown. UF=shipped to San Francisco (though another source says this is San Diego). 231=left-hand drive. 9=Campmobile. 41=50hp engine w/ manual transmission.
