Buick 14073610 Front Chassis Springs

Jack up the rear of the vehicle and support both sides on jackstands at the frame, in front of the rear axle, while also supporting the rear axle with an adjustable lifting device. Disconnect the shock absorber and detach the upper control arm at the differential. If equipped, disconnect the stabilizer bar and remove any brake hose supports, disconnecting the brake hose only if necessary. Carefully lower the axle until the tension is released from the coil spring, ensuring not to stretch the brake hose, and then remove the spring, noting the direction in which the end of the last coil is pointing for reinstallation. When starting a new coil spring, ensure that the bottom of the coil is properly inserted into the socket in the frame and into the form plate on the trailing arm. Jack the axle into place and reinstall the control arm bolt, tightening the bolts with the vehicle's weight on the springs.

Use a ball joint removal tool to separate the stud from the steering knuckle. Once it is loose, raise the jack against the control arm, remove the nut, and separate the steering knuckle from the tapered stud.

The brake lines, shock absorbers, and upper control arms need to be disconnected.

Use the tool to compress the spring as done during removal, install it on the control arm, and then reverse the removal instructions, ensuring all fasteners are tightened to the proper torque.
