Went in and pestered the dealer ...
Well, I went in and talked to a service adviser at the local MB dealership today and I'm not really sure what to make of it. He was very nice, even though I think he thought I was a moron, I didn't do a very good job of explaining my situation. He said they would be glad to do an alignment, but that he doubted that was the issue and that he would recommend experimenting with the tires before spending money on a second alignment (i.e., try rotating them and see if it does anything different, spin each and check for defects, etc.). I showed him a printout of your 124, gxsr, and asked him about the total toe and steer ahead, but he didn't think that was likely the problem, and that the independent shop probably would have noticed those issues (he did know of the shop and said he thought they were very good, the second-best option for a MB alignment, with the dealer being first). Of course, all he had to go by was my description of what the car does. To be honest I have a hard time imaging the tracking would be that affected by the tires, even though now both my indy and this dealer adviser have said that. Or at least, I'm not confident enough to go out and buy $600 worth of tires to replace brand new tires. The alignment is only $90 if I decide to do that first instead.
He did reiterate what my indy and others have said in that he doubted it was my work that caused the problem ... if the new frame were bent or something installed wrong, it would have been very obvious during the first alignment. He also asked about wheel bearings, front suspension, steering linkage and so forth, which was nice, he took his time to help me think of other things to check first. So ... for the heck of it I'm going to switch tires front to rear, and I'll check each for inconsistencies or uneven running. Other than that I'll think about it ($90 isn't very much ...). It's very drivable. It's amazingly comfortable and smooth and sometimes I think "wow, I'm nuts, this car tracks perfectly" ... but if it's windy/breezing or I'm on a truck rut ... then the flakiness starts again.

I forgot to replay earlier about the steering shock, but I did replace that about a year and a half ago. Wouldn't be too hard to check it, though. I did check the wheel bearings a couple nights ago and don't feel any play, and did a visual inspection of linkage, ball joints, control arm bushings and all look healthy. Would front swaybar bushings make a difference in wandering? They look pretty good, but that's the one part of the suspension I don't have a record of being replaced, so it popped into my mind.

... rear swaybar or front?
the rear swaybar bushings really hold the suspension in line... front does very little to keep the car straight.

If you want to really lose sleep and create self-doubt, take it over the grating on the South Market St. bridge. Due to my worn bushings and resulant tire wear, it redefines the word "squirrelly"

to really appreciate this test, you need to do it in the rain on bald tires!

Sorry to chip in again - and I'm doing so without reading the entire thread - but has anyone suggested to check the friction allowance on the steering?
And X2 on the wheel bearings - simple check.

From GSXR: With used tires, definitely. With new tires, very unlikely, but possible. I've had used tires cause problems before, but never new ones. (I usually just have balance / wobble issues with new tires, lol!) I had a brand new set of tires with a bad belt in one that caused handling concerns on a FWD car. The retailer blamed the car, the local Firestone shop diagnosed the bad tire as a "radial pull" caused by a broken/misaligned belt. Armed with that info the retailer simply provided me a brand new tire. Problem solved. Good discussion of what to check for when swapping tires here: http://www.aa1car.com/library/tires2.htm |

The wheel bearings I replaced 4,000 miles ago and set the play with a dial indicator to spec. Then I checked it obsessive-compulsively over and over. I even did a recheck after a couple hundred miles. As for the other parts: Tie rods have about 27,000 miles on them, OE. Drag link has less than 3,000. Steering damper about 8,200. Idler arm bushings 8,300. All OE. The only thing that looks questionable are the LCA bushings, which have about 80,000 miles on them. They don't look alarmingly bad, but I see some cracks starting in the ones at the front of the wishbone. Geez, looking back at my records, I sure have done a lot in the past year! But at least solved a lot ... no vibrations, no shooting sideways in the rear, no awful clunks and squeaks. Yak, I'll check out that tire site, looks like very helpful stuff, thanks! Army, forgive my ignorance, but is friction allowance the same as the steering play? If not, how can I check it? I will say I don't get the sense from the wheel that there's a play problem ... i.e., it's ultra responsive to my input at the wheel. But I guess there could still be play in the box?

Almost forgot, here's a nice big photo gallery from my project. Before and after. I wish I'd gotten some better pics of before but I guess I was a little antsy about getting started and not focused on pictures.
http://www.flickr.com/photos/31264961@N02/sets/72157626151862442/ I do have the old wheel bearings and carrier bearings, which I'll add pictures of when I get around to it. Pretty spooky stuff, those are.

From what I can see (via a Google search) the W124 is of a similar breed to the W123: On the W123 you have a limit on the steering box for the amount of friction that is required to turn the Pitman arm. I understand that this limit can be measured at the steering wheel or at the steering box (either end of the shaft). I think it is worth while looking at chapters 46-0120 and 4650 (It may not be worth your while carrying out the procedures though! But I'm guessing you are running out of options)
