I purchased an indepenent warranty once, never again, they put you in a tough situation. It is like dealing with a sub standard insurance company on body work. Starmark or nothing, all suspension work requires an alignment, balljoints, bushings,(except steering damper).
The lower bushings are hydraulic, which require a special tool, the springs need to be compressed to do this work.
The control arm bushings are $ 81 ea the shock is $ 69 labor is at least 6 hrs, my dealer is pretty honest.
