164 front end twitch or wander

["Daegrigg (Don)" <daegrigg@domain.elided>]

'Trying to sort out a problem on a recently acquired 91 L.  The PO install 225/15 tires that require wheel spaces.    (Plan to return car to stock or may one oversize).  Tire wear appears even on all four corners. Mileage is 144K; car was in accident to rear.  Repair appear OK.  

The problem:

The car experiences a pull/lurch to the right when you let off the accelerator to change gears or slow down - doesn't happen always but most of the time.  When turning left in a moderate to hard turn, the car will also lurch left and then return to previous attitude.  Sometimes during straight a level driving, the car will experience a dead spot in the center and seem to wander - similar to feeling when the toe in/out is wrong.  All these machinations seem to come from the passenger side suspension.  

Suspects:  Strut bearing - no clunks or other usual symptoms.

Alignment:  

Suspension parts:  A arm busing allowing castor change under power or braking?


Suggestions/experience welcome.
Thanks,

Don
