While the car was still on the lift, we moved on to replace the bushings for the front subframe. The PST front subframe bushing kit comes with six all-new polyurethane bushings, washers, and bolts. The trick here is to separate the body from the frame just enough to remove the bushings. We did one side at a time. For the body bushing supporting the firewall, we used a 15/16-inch socket and an impact gun to loosen and remove the old rubber bushing.
