Spacer Installation
TOOLS REQUIRED^ KM-900 Rear Toe Adjusting Tool
^ SA9140E Torque Angle Gauge
CAUTION:
MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON THE HOIST. TO HELP AVOID PERSONAL INJURY WHEN A VEHICLE IS ON A HOIST, PROVIDE ADDITIONAL SUPPORT FOR THE VEHICLE ON THE OPPOSITE END FROM WHICH COMPONENTS ARE BEING REMOVED.
1. Raise vehicle on hoist.
2. Remove rear wheel and tire assemblies.
IMPORTANT:
Inspect for aftermarket shims between rear hubs and rear suspension trailing arms and remove if present.
3. Remove rear suspension lower control arm to rear axle control arm attachment bolts, discard bolts and nuts.
CAUTION:
SUPPORT THE FRONT OF THE VEHICLE TO ENSURE THAT THE VEHICLE WILL NOT BECOME UNBALANCED AND TIP FORWARD, OFF THE HOIST, ONCE THE REAR SUSPENSION SUPPORT IS REMOVED (DUE TO DECREASED PROPORTION OF REAR VEHICLE MASS). FAILURE TO SUPPORT FRONT OF VEHICLE COULD CAUSE VEHICLE TO FALL OFF THE HOIST.
4. Support rear suspension support with a suitable support stand.
5. Remove the four rear suspension support to body bolts and discard bolts.
6. Lower rear suspension support.
7. Transfer washers from old bolts to new 137 mm (5.39 in.) longer bolts (10 mm longer than the original bolts). Insert bolt with washer from bottom of rear suspension support and place spacer between the top of support bushing and vehicle body. Hand start all 4 bolts before torquing any of the bolts.
Torque:
Rear Suspension Support-to-Body
Bolts: 90 N.m (66 ft-lbs) + 90° to 105°
8. Using a die grinder (or equivalent), remove material from the lower control arm-to-knuckle location to make a slot. Remove material from the inboard side of the hole to make camber more positive.
IMPORTANT:
The minimum distance between the inside of the slot and the adjacent hole is 9.5 mm.
IMPORTANT:
Paint exposed metal with primer after making slot.
IMPORTANT:
Do not use the control arm nut retainers since they will prevent adjustment of rear Camber.
9. Using new bolts and new nuts, install lower rear suspension lower control arm to knuckle. Tighten but do not torque at this time.
NOTICE:
Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors. Failure to do so can cause wheel bolts to loosen in service.
10. Position wheel onto hub.
11. Install wheel bolts and tighten in a star pattern.
11.1 Hand tighten all five wheel bolts.
11.2 Use a torque wrench to tighten wheel bolts using a star pattern.
Torque:
Wheel Bolts (Initial Torque): 63 N.m (46 ft-lbs)
11.3 Use a torque wrench to final tighten wheel bolts using a star pattern.
Torque:
Wheel Bolts (Final Torque): 125 N.m (92 ft-lbs)
12. Lower vehicle from hoist.
13. Perform vehicle alignment as specified in the applicable model year L-Series Chassis Service manual using the new steps and specifications outlined in this bulletin.
