I was doin a job on my mates st and he asked me to look at his steering. When the wheels are straight ahead and I rock the steering from left to right there is a heavy knock. Go from lock to lock its fine. Steering is smooth apart from in the centre.

Any ideas? Are they known for steering rack issues?

 

track rod end could be rack itself or bottom ball joint

 

Track rod ends and ball joints are good. Its had a steering arm fitted to the drivers side also. All tight and good. Must be the rack?

 

would it do it jacked up i know of racks knocking when turning with engine off get somene to put there hand on rack feel if its coming from there and check the rest youll be amazed

 

Only does it when the weight is on it and engine running. Ill need to try it running on all 4s on a 4 post ramp I recon
