Rear tire tilted Inward, Rear strut rod bushings??

Hi All,

I'm having a problem with my rear tire. The top of the tire is tiltled inward. I initially thought that this was a result of the chassis being rotten in the spot where the trailing arm connects to it.

So I brought the car into a local mechanic who repaired the bad spot in the chassis and he said that wasn't the problem. He said that the most likely cause is the rear strut rod bushing. I just had a look at this when I was out to inspect the chassis repair and the bushing it dry rotted and cracked and look like it is not sitting correctly on the end of the strut rod.

Do you think that this could cause the tire to be noticably tilted inward?

Any thoughts would be greated appreciated before I give the mechanic the green light to go ahead and replace it.

Also if this is the case would you recomment just replacing the bushings or replacing the whole rod.

Thanks!

It could be the cause. Are you hearing any metal noises as you drive? It could also be simply far out of adjustment.

Since you have one like that, there may be more, so I'd say replace all the suspension bushings. There a number of aftermarket companys that supply nice full kits.

Actually I have only driven it about 20kms since I bought it 4 years ago. So I haven't had the luxury of being able to listen for squeaks yet

My main concern was getting the chassis repaired and that tire straight before I even attempted to make it road worthy.

I just found out that I have a blown rubber in the wheel cylinder and a "burnt valve". Oh my the list goes on and on....

In any case I told the mechanic to go ahead and fix the wheel cylinder (obviously) and also to "fix" the valve (God I hope he knows what he is doing) he said that it would take him about 6 hours labor @ $30.00/hour + the cost of the new valve kit. Does that sound reasonable?

Thanks!

There is a bushing at either end of the rod. On the rear end end there is the adjustment for wheel alignment. If it has slipped then the bottom of the wheel moves outward. Since the tire toes in then the problem is misadjustment. May have been done to correct for worn bushings.
If one side has aged chances are so has the other. The only problem I ran into was removing the shock mounts. Both were rusted to the pont that the sleeve on the bushing and the mount were fused.
After the mechanic replaces them make sure you have the rear wheels aligned.

You may consider instead:

There is yet another possibility, and that is that your "stub axles" are worn on the ends. The half shafts and stub axles serve as both a suspension and driveline component.

Think of the half shafts and stub axles as the "upper A Frame" of your rear suspension. Think of the camber rods as the "lower A Frame".

If the ends of the stub axles wear within the differential, and they can and do wear to the point where the "C" clips fall off, you "shorten" the upper A Frame, and cannot compensate for the negative camber by adjusting the camber rods.

That's why you'll see so many Corvettes with bent camber rods...it was done in an attempt to adjust the camber to specs when there was no more real "adjustment" left in the eccentric adjuster.

SO....could be bushings in the strut rods, but might also be excessive wear on the stub axle ends. If it is, the cure is to replace the stub axles, and maybe rebuild the rear end. Hope this helps. Chuck
