Ok I told you guys the problem of grease streaks on rims and what mechanic says about being brake dust or tire cleanser. Took to the dealer and they checked it out. Says both front upper arm controls need replacing at $1040. Both front lower ball joints need replacing at $516 Drive belt needs replacing at $275 and realignment at $129. This is a 2005 Jeep Liberty. Do these prices sound right? Oh and says one of cv boot is cracking ( forgot which one) Cost me $129 to find all this out. Can this be done by a drive to home mechanic? He doesn't charge so much.
