The OTC 4247 rear suspension bushing tool for Heavy Duty vehicles makes Pivot and D-pin bushing removal and installation easier tasks. Because the patented design allows the tool to be mounted to the suspension piece, the weight of the tool does not need to be held in place during operation. It also includes centering adapters that align the tool and reduce the likelihood of bushing damage or improper installation. With the included OTC 4106A 25-ton cylinder, even bushings covered in road dirt and salt are easy to replace. This master kit version of the tool includes an OTC Stinger Series 2510A Air/Hydraulic Pump and the needed hose and couplers to make it ready for use right out of the box.
