Default Weird Problem...

Recently I just did a major tune up on the suspension in the 1996. I replaced the rear struts with monroe sensatrac'*, I replaced the front right control arm (it was bent) and I had the whole mess aligned.

It rides great now, I have much more control, and the passenger side tire doesn't rub inside the wheel well now.

The problem is, when I make hard right turns everything is dandy...but when I make hard left turns i get what sounds like a tire squealing. Only does this on really hard left turns, and not right.

Any ideas?

Sounds to me like one of the shields is not mounted properly, or sitcking out like mine was. I had this problem but mine was hitting the tread. I found that one of the splash shields behind the tire to guard water from getting into the engine compartment needed to be pushed in toward the engine. I would say to turn the wheel to the direction that it squeals and look in the wheelwell to see what the tire may be hitting. It'* probabally not going to be really noticable (look hard for wear marks in the plastic shields) since it was worse before the alignment, and now its just a light squeal. Start with the easy stuff. Let us know what you find.
