My Griff pulls slightly to the right, had the allignment checked out but it still pulls slightly when it has to go straight. I was wondering if the steering rack has a dead centre which could explain the slight pull to the right (2 degrees). It feels the steering wheel wants to return to this position when driving straight. Thanks Bas

May be a silly question but have you carefully checked the tyre pressures ?

Did the person who checked the geo know what they were doing, the front can be bang on but if the rear toe is incorrect they can rear end steer. Had this on mine where the toe adjuster lock not came ( or was left) loose. If you went to slow fit or the like they would have probably never seen an adjustable rear end. Fairly easy to check with a bit of string, two axle stands a steel rule and a level.

Easy???? I'm still trying to get a straight piece of string hehe

Rear Toe can be set correctly, its the relationship to the c/line of the car that is often misaligned (thrust angle). I think thats what you were saying wink

Worn Diff lsd can pull, I think thats mainly when you apply power rather than coasting.

And my 'silly' question is: do you have the same make/type/size of tyre on each 'axle'. Is the wear even?

Hi, we don't have many tvr's driving in northern holland so I'm not 100% sure if the guys who did the allignment knew how to set it up properly. Gave them the steve Heath book for guidance plus his recommended settings. They didn't change the camber but only the front wheel toe-in. They mentioned the rear was still ok. What settings do you use on your car? Might have it done again. Tyre pressure was spot on a week ago, will check it again to make sure. Thanks bas

The exact settings are really a matter of preference so you will probably find no two cars are the same, but the key thing is that both sides are set the same. Worn bushes are a fairly common problem that can allow the suspension to move about and “self adjust” Another obvious one would be a sticking brake calliper on the side it is pulling towards. You should be able to check this by lifting both wheels off the ground. Applying and releasing the breaks and checking that both wheels are free to turn.

Check the tyre size, condition, pressures are the same left/right. Check the rear geometry is symmetrical and you have equal camber at the front. If the corner weights are out you can get a similar effect, it can also happen if you have worn suspension bushes. There is no internal self-centering within the rack.
