Like know cost replace upper mount(top plate) for front suspensions, and do guys know how much labor would cost? I don't have Oem suspensions, there tein.
a seasoned mechanic with a lift can probably do each side in 30 minutes but most places charge by the hour so you'll get charged for 3 hours plus whatever extra charges they like to tack on for latex gloves and band-aids. then they'll probably charge you oem price for aftermarket parts from who know's were. not to mention your going to have to get an alignment when your done. or you could grow a pair and do it yourself considering how easy it actually is to do. http://gametrax.net/springs/index.html
