So looking at the rear of the car, the top of the wheels are pointing in and the bottoms pointing out. Thermo suggested this is probably worn rear bushings.
Does anyone have a link to replacing them with pics included?...or a thread with full instructions?
On a side note...I think the lower bushings on the rear shocks are bad as i can "twist" the shocks when i grip them, one shock has moved to the far right extremity of the lower mounting (if that makes sense)
Are the shocks easy to replace?....any tips?...favorite brand?

 

Or maybe these eccentric bolts on rear lower arm are not adjusted in right way

 

He's talking camber and the eccenttrics adjust rear toe. Most cars are set up with negative camber /\ ?tires look like this when viewed from the front or rear. I would get the alignment checked. You can only set front and rear toe. X types imo have poor suspension for strength and longevity. They tend to bend struts easily on potholes, shortcutting a curb in the rear bends the trailing arms aka hub carriers. The bushings as far as i know are only avail with the arms, except the front trailing arm bushing. Untilk your front or rear camber approaches -2degrees i would not spend the money and enjoy the faster cornering speed youll be able to take.
Reasons for this most often like thermo told you is bushings that are wornout. Yes the shocks in the rear are very easy and should take no more than 30 minutes on your back. The fronts are a differant story. If you have uneven camber from side to side you can loosen the subframe when doing an alignment and shift it slightly to even the camber out. But really only if there's more than .5 degree differance or more.
