Q: How do you remove the Coil Springs on Pontiac G6?
A: To remove the rear wheels, start by loosening the lug nuts and blocking the front wheels to prevent the vehicle from rolling. Then, raise the rear of the vehicle and secure it on jackstands. Once the vehicle is properly supported, remove the rear wheels. Next, use a floor jack to support the lower Control Arm. Install a spring compressor tool and compress the spring until it is loose against the insulators between the body and lower control arm. Unbolt the outboard end of the lower control arm from the knuckle and lower the arm and the coil spring using the floor jack. Remove the coil spring from the control arm. If a new spring is being installed, carefully release the original spring from the compressor tool. If the spring is being reused, leave it compressed with the tool in place. To install the components, follow the reverse order of removal and tighten the lower control arm mounting fasteners to the specified torque.
Q: How to replace a strut and coil spring assembly on Pontiac G6?
A: If the struts or coil springs show signs of wear such as leaking fluid, loss of damping capability, chipped, sagging or cracked coil springs, it is important to explore all options before starting any work. The strut coil spring components cannot be serviced and must be replaced if there is a problem. However, there may be strut assemblies available that come complete with springs on an exchange basis, which can save time and effort. Before disassembling the vehicle, it is recommended to check the cost and availability of parts. To disassemble the strut and spring assembly, the strut clevis bracket portion should be mounted in a vise. A spring compressor should be installed on the spring following the manufacturer's instructions to relieve pressure from the upper spring seat. The damper shaft nut should be unscrewed while holding the damper shaft from turning. The nut and upper mount should be removed and laid out in the order they were removed. The rubber portion of the upper mount should be checked for cracking and deterioration, and replaced if necessary. The upper spring seat should be removed from the damper shaft and the rubber portion should be inspected for cracking and hardness. The bearing in the spring seat should also be checked for smooth operation. The dust boot and rubber bump stop should be slid off the damper shaft and checked for cracking and deterioration, with replacement if needed. The compressed spring should be carefully lifted from the assembly and set aside. To reassemble, the damper rod should be extended and the rubber bump stop and dust boot should be installed. The compressed coil spring should be placed onto the lower seat of the damper, with the end of the spring against the raised stop. The upper insulator and spring seat should be installed, followed by the upper mount and mounting nut, which should be tightened to the proper torque specifications. The spring compressor tool can then be removed, and the strut spring assembly can be installed.
