Rear end play

[Trex]

Its a 02 ls 90k... I just had new Bridgestone Protenza tire put on it about 300 mile and got an all wheel allignment. The car handles fine on non grooved road, however on rain grooved roads it feels like the rear passenger wheel is loose. This is not a constant thing and not a shake, its more of a wobble. Honestly it feels like the hole axle is moving in and out and when it does it get the car rocking side to side a bit as if the car is dog tracking and its trying to correct itself. I have no wheel noise. Raised the rear end and no tire play, so i wouldn't think it would be the wheel bearing. I have taken it back to the tire shop 3 time and nothing has changed. They say everything looks fine and there are no rain grooved roads never by for them to drive on, so that I can have them feel what I am talking about. It is driving me crazy and honestly at times doesn't feel safe at all. I am going to take it to the dealer but was just looking for some possible insight on what this could be. The rear wheel did make a big clunk sound one time since the new tires were put on but I think that was the traction control because even with the new tires it seems to want to hydroplane. Any help would be appreciated

If the toe links are not properly aligned, you will have rear tracking - especially when getting on the gas. Are you sure they are aligning it properly? Also I would check to see if there is any play in the rear toe-links whatsoever. Though I am sure a reputable shop would find this type of problem...

Thought this was a link to a video.

Check for directional tires mounted wrong, not sure on your tires if applicable.

Ditto on the rear toe links.

If this is a new problem since tire purchase, alignment was done wrong or tires are effed. Change to the best alignment shop in town to resolve and have original shop refund their alignment. Prove it with a printout, if necessary.

+1 on the printout. Get before and after on the printout. Did they tighten the toe link after 'adjusting' it (if they actually did align it). I work at a shop (and do alignments) and there is one guy I work with that alters the alignment heads to show its in spec instead of actually adjusting it

Good advice. I had my left rear toe link loose. I still haven't had an alignment done though.

What a a$$ hole. I'd be pissed and tell me manger. If that didn't work I'd try to find another place to work.
