Some of you might remember me posting a few times about my wheel falling off in heavy traffic?

http://www.prettyfar.com/?p=239

Info:
1988 Integra.
Auto
1.6

Situation:

New mechanic investigating noise takes wheels off.
Thinks driveshaft is bent as it has no movement between it and the gearbox, that it is pushing against the gearbox.
Not movement as in rotation, as in horizintal, in and out.

Investigates more, concludes it is the wrong one.

Suggests it is a prelude, not a integra shaft.

Question: Does this make sense?

It's possible, although I've seen (once) a Vigor suffer the same fate as the shaft was so worn that it eventually let go. IIRC the car I'm referencing had almost 300K.

So someone replaced the shaft with one from another car that isn't quite the right length?

I guess it's entirely possible, but could be very hard to notice if there's not much difference between them. Also, it may be that it's ok most of the time, and only causes an issue with the suspension at full droop or full compression, which makes it an arse to confirm.

If your mechanic is correct, it sounds believable - lack of plunge depth meaning the shaft was putting a hell of a lot of strain on the ball joint, until it failed.

Is the inner joint a CV/Birfield type (two fat rings with ball bearings between) or a tripod type (three big roller bearings that go into machined slots)? If it's the latter, maybe bits of roller bearing have broken off and jammed the plunge movement. Did you mechanic say anything about finding lots of bits of metal in the oil?

That is what the new mechanic is suggesting, yes. That it is too long and jammed up, pushing against the gearbox.

With both wheels off, we said one side was ok and showed me one shaft could be pushed in, the other not. Also when rotating the "bad" one by hand the car noticeably moves.

I intend to have him measure the driveshaft once removed, just for peice of mind.
At that point though I'll have spent $240 for the shaft + labor point of the thread is really to see if anyone will call bullshit.

Its not currently broken. Does this help?

A bowl in hand is better than two on the bush.

I would have to check at work, but I think that the Prelude axles have a different spline count. You might have an axle from a 94-00 Integra. You can get the compressed lengths of both axles from Autozone to be sure.

Yep, fuckers sure did put the wrong drive arm in. Sude by side the correct one is shorter.

I can't imagine the wonderful effects that had on your alignment...
