Yeah don't trust a local shop.. Parents blazer had tires put on about 4 months ago or so.. Before putting new tires on I replaced the balljoints, shocks, idler arm, wheel bearings. The guy at Merchants said I needed new shocks, and upper & lower joints. I asked him to show me the play in the front end and if he noticed those shocks were absolutely clean. Obviously he was trying just to make a few extra bucks or something. They think when your rig is on the lift, you can be taken advantage of.. Don't let that happen to you.
