CASTER OFFSET
FRONT LOWER CONTROL ARM REAR BUSH
UNIVERSAL FITTING INSTRUCTION Code: Z5101
Caster bush kits are designed to improve handling performance, vehicle straight line stability as well
as cornering grip through increased static caster and dynamic negative camber gain. Polyurethane
bushings also improve steering response and feedback.
We recommend that all work be carried out by a qualified technician. Sound motor vehicle mechanical knowledge is
expected. In some countries and states, fitment may only be legally performed by a licenced mechanic. Check the
regulations in your area.
Caster Kit components will vary depending on the individual product and application.
Caster Kit fitment and adjustment.
1. Measure wheel alignment settings prior to commencing any work.
2. Raise front of vehicle, support on safety chassis stands or hoist, and remove front wheels.
3. Remove lower control arm from vehicle. In some cases, it may be necessary to remove other suspension
components.
4. Remove original rear bush from lower control arm or housing using suitable tools. In some cases, workshop press
may be required.
5. Clean any flaking paint, rubber and dirt from bush housing, smear grease supplied only onto the bore and flanges
of the bushes and fit to control arm or housing.
Note: While some Caster Kit types are pre-set for extra caster (not adjustable) and some types are
adjustable, all are designed to improve handling performance by increasing and maximizing caster
settings on one or both sides of the vehicle. For correct fitment and alignment of bushes and crush
tubes, refer to Fig. 1 for vertical pivot bush, or Fig. 2 for horizontal pivot bush.
6. Refit lower control arm, and lightly tighten all fittings.
7. Refit wheels, lower the vehicle and settle suspension. DO NOT drive at this stage.
8. With the suspension settled, and the vehicle at normal ride height, tighten all fittings to original manufacturers
torque specifications.
9. Test drive the vehicle, and re-check all fittings.
10. Measure new wheel alignment settings, and adjust as required.
Post installation check and maintenance.
- Re-tension all fittings after a settling-in period, but not later than 100kms (60miles) after installation.
- For noise and friction free operation, carry out periodic inspections and maintain proper bush lubrication.
