Judder and Knocks

[cg084]

All,

 

I have a 94 N/A Supra. In the mornings if i am reversing with the sterring wheel turned all the way clockwise. On reversing I get a nocking noise and one hell of a judder. Its like driving over a deep pot hole.

 

As far as i can tell this only seems to be bad when it is cold. For the most part i tend not to do anything with full sterring lock on but it is unavoidable at the car park for work.

 

I have tried the same when i have driven the car for a while and it is warmed up.

 

Does anyone have any ideas as i believe this is not anthing with the subframe bolts. Tyres and wheels are totally standard and are not oversized or wider. Are all inflated to 2.6Bar tyre pressure as per stickers on door piller.

 

Does anyone have any ideas of what else to look for.

 

Cheers cg084

All,

 

Still no response here. Does anyone have any ideas at all about this. Have noticed that there is more turn to the steering if applying full lock to the right than there is full lock to the left when the wheel is in dead centre.

 

Not much in it but possibly a cause.

 

Any ideas???

Yes this is a common problem as far as I know. Do a search cos I know there is more about it somewhere.......

It's the wheel offset and castor angle dragging the tyre sideways as well as the road turing it. Wrong offset wheels make it worse, although stock ones, with certain tyre combinations will exhibit this, too, on certain surfaces. Nothing you can do unless you have none stock, incorrect wheels on it. I wouldn't worry about it if it drives OK and it has the right offset rims (50mm)
