WARNING:
- Do not re-use any fasteners that are worn or deformed in normal use.
- Some fasteners are designed to be used only once and are unreliable and may fail if used a second time. This includes, but is not limited to, nuts, bolts) washers, circlips and cotter pins. Always follow the recommendations in this repair information replace these fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.
CAUTION:
- Do not attempt to weld or straighten the load-bearing components or parts of the suspension.
- Do not attempt to move a vehicle from which the drive axle has been removed. Otherwise, wheel bearing damage will result. If the vehicle does have to be moved, install an outer CV joint in place of the drive axle and tighten to 50 Nm (37 ft. lbs.).
- The bonded rubber bushings can only be turned to a limited extent The bolted connections on the suspension links should therefore only be tightened when the vehicle is standing on the ground.
