wow! thanks for all the replies guys! sorry I haven't been back but the computer decided crap out as well. 
  
 ok, lets see. in order. 
  
 I THINK I've had the wheel berings checked (it's been looked at by 4 differnt mechanics), but I will double check that. 
  
 Morgan: it seems to be pretty much even now, slightly more on the left side I think (my wife thinks it's more on the right side) 
  
 millage is in the mid 90's 
  
 I'll try the figure 8 thing Ranger., thanks 
  
 there is a VERY clear "click" when stationary and shifting from first to reverse, just as it's hitting or comeing out of reverse. 
  
 Urabus: they have pulled off all 4 wheels, rotated them, did the wiggle thing. all seemed solid. the dealer seems to be leaning twards replaceing the Viscus coupling. $800-$1000 bucks. (so far they have "fixed" my breaks three times and they still squeel and the car had $1200.00 worth of repairs within 30 days of me buying it, I DON'T trust the dealer) 
  
 I had the tires checked, all same size. 
  
 I'll try that figure 8 thing, and see about getting the rear end diconected ptrbilt 
  
 thanks much guys, now at least I have some ideas.
