[DeTomaso] Wheel Bearings GT5-S

[Asa Jay Laughton]

Charlie,

Something else I don't know if anyone else mentioned... a-arm bushings. 
If they are getting worn a little, you'll see it as a motion in the 12-6 
position. However, in your case, I'd bet things are just fine and you're 
probably seeing normal play.
