  Q: How to Replace Coil Springs with Independent Rear Suspension on Buick Terraza?

  A:

  To replace the coil spring with independent rear suspension, lift and then support the vehicle. It is removed of the wheel and tire assemblies, after that, Brake Calipers, parking brake function cable attachment and brake, and the caliper attachment. Detach the abs electrical connector and remove the mounting bracket for the connector. Use a utility jack to prop the lower Control Arm, and remove the stabilizer link on the lower Control Arm. Use the j 41820 Ball Joint/stud separator (J 41820) to separate the Ball Joint from the knuckle and then drop the lower Control Arm with the utility jack to release the coil spring tension before removing the coil spring. For the installation, it is crucial to install the coil spring without scratching or chipping the coating. Lift the arm-manufactured vehicle using the utility jack which enables loading of the suspension, and then attach the j 41820 (J 41820) in linking the Ball Joint to knuckle. Replace the stabilizer link to the lower Control Arm, lift on the lower Control Arm with the utility jack, and install abs electrical connector mounting bracket and connect the abs electrical connector. Finally, restore the brake caliper mounting bracket, parking brake cable mounting bracket, brake calipers, and wheel and tire assemblies before lowering the vehicle.

  Q: How to service and repair the front coil springs and shock absorber on Buick Terraza?

  A:

  Service and repair of suspension struts begins with removing the strut from its vehicle position. Set the strut inside the strut spring compressor (J 45400). Set the compressor's forcing screw to extend the spring until the strut displays unimpeded motion. A 45 torx(R) socket should be used to secure the strut shaft before using the strut rod nut socket (J 42991) for upper strut mount nut removal. The strut spring compressor (J 45400) allows removal of the strut after which you can loosen its forcing screw for upper strut mount and coil spring extraction. Here's how to assemble the strut spring compressor (J 45400): first place the coil spring and upper strut mount inside the compressor and compress the spring once more. Load the strut into position between the coil spring and upper strut mount before installing the strut retaining nut loosely. Hold the strut shaft in place with a 45 torx(R) socket while using the strut rod nut socket (J 42991) to tighten the upper strut mount nut to 85 n.m (63 lb ft). Finish by removing the strut from the strut spring compressor (J 45400) then reinstall it into your vehicle.
