240z crabbing from right hand rear toe in!

[JamesP]

hey guys the 240z i bought has possibly had a hit at some point and the rear right hand side wheel has 5mm toe in. The result is making the car crab to the left! :-\

 

I have had the car wheel alignment done and all the other wheels are straight. Ive had it on a hoist at Adelaide z cars, and it all seems to be straight underneath and the body is all straight, the wheel doesn't buckle or wobble either so the hub isn't bent at all! I was speaking to a friend who races a 240z and he said he had the same problem and had to re slot the bolt hols on the torsion bar that runs behind the diff to square it up.

Has anyone had this problem, or any idea how to fix it.

 

Kind regards

James

Cheers lurch, how do they work?

I had the same problem.  My rear right was closer to 10mm toe in. Everything looked straight underneath. 

 

I just got TTT rear adjustable control arms to solve the problem.

My first 260Z I had used to crab crawl; problem I traced to the two bits of "L" shaped brackets that come from the floor behind the diff and support the rear A arms bushes towards the rear and that straight part that runs right across the rear of the diff. One of those brackets was bent by about 4-5mm. If you remove them and put them back to back, you can easily see which one is bent. It's a pretty easy fix if that's what it is.

ahh yes,

that is why this part of the design is flawed & subsequently phased out to the modular cradle type....

keeping the control arm mounts square to the car, is imperative, even utilising the slop in the bolt holes to chassis can cause above.

so can backing into gutters mind you....

Hmm, I might check out that on mine. I have those offset bushes already and although they are set for maximum toe out, I still have both rear tyres with a few mm of toe in???

Yep, even a decent hit of the wheel from behind by backing into a gutter can bend those brackets. I eventually found a pair that were straight and that solved the crab crawl.

Also, make sure the bolts that clamp the control arms are tight, mine used give me rear steering because they were loose, but would crab walk on straights after the corner.  Once they were done up really tight, they have been good since, so maybe check that too.

Thanks guys all very helpful information!! should be able to sort it out now
