REMOVAL OF STOCK TRAILING ARMS
1. Place the car on level surface and place tire chocks in front of and behind front tires.
2. Support rear of the car 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 car off the jack stands.

Do not remove both trailing arms at the same time or the axle will rotate and the trailing arm installation will be much more difficult.

5. Remove the front trailing arm bolt.
6. Remove the trailing arm.
7. Clean frame at trailing arm pivot area with a wire brush.
