So… related to my last post, here’s yet another issue that’s come out of the 60K mile check-up (of my 2005 VW Passat Wagon GLX). The technicians noticed a “wobble” from the rear of the vehicle at 15-25 mph (that, mind you, I have never noticed). Their inspection of the tires noted that the left rear tire’s inner tread was “showing steel.” After performing some suspension work, they did an alignment check. They adjusted the front axle (since they can do that), which is in alignment now. The rear axle, however, is out of whack. The left individual toe is at +0.50 degrees (shown in red on my diagnostic) and the right individual toe is at +0.10 degrees (shown in green), for a “total toe” of +0.60 degrees.
Their suggestion – mind you, this is from an independent mechanic – was to either re-shim the rear axle (which cannot be done at this particular mechanic’s shop), or to replace the axle in full. Either way, they’re telling me this is not an inexpensive repair, and that I should call my insurance company to get them to cover the amount past my deductible.
What do you guys think? Is re-shimming workable? How much would I expect to pay for that? Can it be done at any body shop? How serious is the problem? Better to just replace the axle in full?
