Rack/pinion issues

Pontiac grand prix 2007…ok o broke mount bracket on pass side and so I replaced it…It laster abt 2 months then broke at same place the right mount bracket …I replaced it then again along with shock and spring and it has broken…why is it breaking please.

:dizzy_face:

Do you have a question?

Possibly as said in one of your other threads that another mount is broken or you have some part of the suspension that is weak . Now you know why the vehicle was gifted to you . Someone just wanted it gone.

I think if I had that problem I’d loosen all the engine and transmission mounts and run the engine to see if that would cause everything to move into the proper orientation, then re-tighten the mounts.

I expect you already know OP that driving a car very hard, like it is a race car, can quickly damage engine/transmission mounts and various suspension components. Are you doing this?

@Bob_Burnett If you keep posting the same question, you likely will get the same answer.

Something is not right. The car is bent, a weld is broken, something in the suspension is loading up the rack mount so it breaks. That can’t be diagnosed over the internet. The car needs a thorough inspection from underneath, preferably with a large pry-bar and a mallet to find the root cause. If that doesn’t happen, expect to keep replacing steering racks.

the rack is mounted to the subframe. the lower suspension strut/control arm is mounted to the subframe. you do verify the rack is centered by turning the input shaft left/right before you install it? so, steering is even? 2 turns left and 2 turns right when done?
rack is square. it is bolted to body properly at 4 corners?

I’ve gotten 3 different ones so far…lol

Thx. I’ll keep that in mind

Yep…thank you very much.

That’s a good idea thank you
