How to install upper ball joint spacers in offroad car?

To properly install upper ball joint spacers in an offroad car, you should follow these steps:

  • Make sure the car is properly positioned and securely supported. You may use a jack or jack stands to stabilize the car and prevent it from moving during the spacer installation.
  • Remove the wheel.
  • Disconnect the upper ball joint by unscrewing the bolts or nuts that secure to the control arm and wheel knuckle. This may require using special tools.
  • Instal the upper ball joint spacer and new ball joint (recommended). Make sure the new spacer is tightened down securely and is firmly mounted on the ball joint. The spacer is very precisely designed so that both the spacer and the ball joint have the largest possible support surfaces, therefore the mating parts must be thoroughly cleaned before installation to ensure proper surface adhesion. If the edges do not adhere properly (depends on the manufacturer of the control arm or pin), they should be filed down to obtain the correct contact surfaces.
  • Reinstal the upper ball joint to the wheel knuckle. Make sure the ball joint is securely fastened and stable.
  • Reinstall the wheel onto the axle, using the same lug nuts or bolts that were removed during the disassembly process. Make sure the wheel is tightened down securely and the nuts are tightened to the proper torque specification.
  • Repeat the process for the other side of the car. Once you have finished installing the spacers on both sides of the car, it is a good idea to test the suspension by bouncing the car up and down and checking for any issues or abnormalities.

Depending on the design of the vehicle, in some cases the angle of the wheel is also adjusted using eccentric bolts, e.g. on the Pajero III, IV
