[T3] Alignment

[Daniel K. Du Vall]

How long did it take to wear the tire out on the inner edge?

I would still say that there is a fair amount of toe out on that side assuming its only one side.

Toe out causes a tire to scuff as it roles on the inner side of a tire and toe in is the opposite.

All our AC VW have a some amount of negative camber but if lowered, which I assume not in your case, increases the amount of negative camber.

The more toe in combined with negative camber would cause that sort of wear in your picture.


Far as the bushings assuming they are the OEM rubber ones Jim's right in that its more than likely not the cause.

The Red urethane ones would state some one has replaced them and doubtful that they have worn enough to cause this also.

The red ones should be visible without any disassembly but maybe a bit of cleaning.

Here is a link that show both types:

The spring plate bushings are intended to "squirm" internally. If
they slip, either inside or outside, they will wear and fail. The
squeak you're hearing could be from slipping, or it could be from
metal to metal contact somewhere.

As Keith mentioned, the OE bushings are a real bear to install,
because they are so tight. I suspect that the polyurethane
replacements are made slightly smaller, so they will be easy to
install, but that makes them likely to slip and wear, so I'm
skeptical about their long term reliability.

In 45 years, the ONLY diagonal arm bushings I've ever replaced were
on one side of a '71 squareback where someone had removed the pivot
bolt and neglected to put it back. Left unconstrained for years, the
bushings ran into something else and got distorted to the point where
a replacement pivot bolt would not go in. I had to remove the old
bushings and install new ones to restore the rear suspension
geometry. The owner admitted that this quieted down the ride
significantly, now that the diagonal arm was no longer banging around
back there.

In other words, I doubt if there's any problem with your diagonal arm
bushings, assuming the pivot bolt is in place.
