Default Rear Toe Adjustment

Does anyone have any idea what the tool for adjusting the rear wheel alignment looks like. I assume it fits between the to raised grooves in the knuckle bracket.

The local place used something similar to a tuning fork but with shorter legs when they did mine. They fitted it to the holes in the trailing arm.

Autodata show an illustration of a tool 64.021 which looks like an elliptical tube.


Sorry I couldn't find any further reference, other than an expired eBay advert in Germany.

I see you've been on the forum quite a while so I guess you know about the ---How-To----section.--

Lots of questions about wheel adjustment and the answer you seek might be in there.--

I believe there are other 'unofficial' tools that are used. I've used a rubber mallet.

Looking at the photograph, I'd say the one of the bolts where the two raised grooved are located on the plate, is removed and replaced with a stud, the tool located over that, and then with the other bolts slackened, the plate can be moved in a controlled fashion with a t bar or similar turning the cam of the tool.

Slacken the adjuster plate bolts, lube the plate with a spray and tap the trailing arm near the front bush. I would only do this to 'tune' them following a tracking station session. Only gentle taps. I use the Gunson Trakrite for tuning.

Default Rear Toe Adjustment

Thanks for the photo of the official tool. I asked because I have all the suspension off for a rebuild with new links and wondered if I could make a tool. Whenever I have had the alignment done in the past I think they use the 'hammer' method which I guess makes it difficult to get the adjustment spot on.

Get a Gunson Trakrite shear gauge and you'll get it better than the local depot. The primary issue with DIY tracking is to have the Thrust Angle in spec first. I can't see a reliable DIY method of doing that - I suppose sombody will tell us how? So it needs a professional setup before you do the final tweek. This 'tune' as I call it is the difference between the toes being within spec and hitting the sweet spot for your particular car.
