Dry Steering Judder

[400BHP]

When I dry steer without moving ie. when manouvering, the steering wheel judders, someone told me this is because the tyres have got such enormous grip, as the grip is overcome by the hydraulics it sort of snatches and releases (best way to describe it) my tyres are nearly brand new and it only does it on some surfaces. Anyone else had this?

Also, when I grip my steering wheel and move it up and down at top and bottom (as if i was checking a wheel bearing) there is a small amount of play, none side to side just top to bottom. anyone else got this??

I get it in multi story carparks where the surface is smooth. Hardly ever get it on any other kind of surface though.

As for the steering wheel play: The Supra wheel is height adjustable, isn't it? Is yours locked properly?

Yeah its a spring loaded lever, i think its the adjustment mechanism, not the column bushes that are moving.

Your not alone I get this too but I try not to turn the steering without the car moving as it puts great stress on the rack mounts. Unavoidable at times though.

You should NEVER EVER turn a power assisted wheel without moving the car either backwards or forwards. Period.

Yes its juddering cause its having to over come the friction between the tyre and road.

I actually get this when there is poor friction, like on gravel or grass. I put it down to me being able to turn the wheel too fast for the power steering due to the low friction.
