When I reverse my sierra on full lock I get what feels like a wobble from the near side front wheel, it then wobbles when I straighten up and I'm not sure but I may get wobble when I drive now. I've changed the TCA's (both sides), the anti roll bar bushes are poly's. I've had the tracking done. It's not the wheels as I tried my old set on it and it still does it and there's no play in wheel bearings.

Can anybody offer any advise?

maybe the top strut mounts?

 

When you say top strut mount, do you mean the lower cup that the sits on top of the spring mount? I have poly top bushes and the top nut is torque up correctly.
