REMOVAL OF STOCK TRAILING ARMS
1.
Place vehicle on a level surface and place tire chocks in front
of and behind the front tires.
2.
Support the rear frame of the vehicle on jack stands and
remove the rear wheels.
3.
Place a floor jack under the differential and lift up slightly to
remove tension from the trailing arm bolts. Make sure not to
lift the vehicle off the jack stands.
Figure 1
Note: Keep floor jack under vehicle during the complete removal
and installation procedure. Remove only one arm at a time.
Removing both could cause the axle to rotate making
installation difficult.
4.
Start with either trailing arm and remove the rear bolt. Replace the bolts in same direction as original.
5.
Remove the front trailing arm bolt.
6.
If you are having difficulty removing the trailing arm bolts, remove the lower shock bolts and the rear springs to aid
bolt removal.
7.
Clean the frame at trailing arm pivot area with a wire brush.
8.
Remove the pressed-in factory rubber bushing from axle housing. Note the direction of bushing in the axle housing. Be
careful not to damage the axle housing.
