Q: How to replace the rear coil springs on GMC Envoy?
A: Vehicle owners should start by supporting the vehicle while raising it then install the rear axle support. Proceed by eliminating the shock absorber lower mounting bolts while keeping the rear axle from reaching the frame contact point to prevent damage on the upper control arms. Handle the Coil Springs with extreme caution when lowering the rear axle because rough handling will result in coating damage which causes early component failure. Proceed by taking out the rear Coil Springs next. Place the new rear Coil Springs into position and lift the rear axle. Fasten the shock absorber lower mounting bolts to 85 n.m (63 lb ft) of torque. The final step involves taking the rear axle support off and then lowering the vehicle.
