Mechanic's Checklist
Good parts need good installation. To make sure our heavy-duty leaf springs work their best, our chassis engineers offer these expert tips.
Always Replace U-Bolts: When putting on new leaf springs, always use new heavy-duty U-Bolts. Never reuse old ones, as metal tiredness can cause them to become loose.
Correct Torque Control: Please follow the car manual for the right torque. Only tighten the nuts fully when the vehicle’s weight is fully resting on the ground.
Bushing Grease: If you are using polyurethane (PU) bushings, always use the right grease to stop annoying noises later.
