Q: How to replace the shock absorber on a 2WD with Z85 or ZQ8 specifications on Chevrolet Colorado?
A: The upper mounting nuts of an absorber/spring assembly need removal to replace the Shock Absorber on 2wd vehicles equipped with z85 or zq8 specifications. Support the vehicle at a height to gain access to the tire and wheel. Start by removing respectively the absorber/spring assembly bolt and nut after which the front stabilizer link follows. Take out the absorber/spring assembly from the vehicle while simultaneously avoiding damage to the Coil Springs' protective layer. The j 45400 strut spring compressor requires the absorber/spring assembly installation where the Shock Absorber should move without restriction while the spring remains compressed. Procedure: apply turning force to the spring compressor forcing screw to minimize coil spring height and detach the absorber upper retaining nut as well as bushings and washers before extracting the absorber from the assembly without spring disconnection from the j 45400. Place the absorber inside the j 45400 and position absorber bushings and washers next to the mounting bracket before tightening the retaining nut to 20 nm (15 lb ft). Put the absorber/spring assembly into the vehicle after removing it from j 45400 by tightening the bolt and nut assembly to 110 nm (81 lb ft). The installation process starts by putting the front stabilizer link on followed by the tire and wheel and then lowering the vehicle until you finish by screwing and tightening the upper mounting nuts of the absorber/spring assembly to 27 nm (20 lb ft).
Q: How to replace the shock absorber on a 4WD on Chevrolet S10?
A: To change the shock absorber on a 4WD vehicle, first raise and support the vehicle, remove the tire and the wheel. Now remove the shock absorber lower mounting nut and bolt then upper nut and bolt in order to remove the shock absorber. For installation, fix the shock absorber to the bracket and fit the upper and lower shock absorber bolts in the correct direction. It is imperative to tighten the shock absorber mounting nuts and bolts with the front suspension loaded and 73 Nm (54 ft.lbs) of torque achieved on the nuts for the upper and lower mounts. Finally, install the tire and wheel before lowering the machine.
Q: How to service and repair a gas charged shock absorber on Chevrolet Tahoe?
A: Proper safety needs must be established before starting any work on the gas charged shock absorber by putting on safety glasses to shield against injuries from centerpunching and drilling operations. Use a centerpunch to make an indentation which should be located 10 mm (0.4 inch) below the tube bottom. Position the shock absorber in a vise which should have its shock absorber rod completely extended horizontally. Position the drill bit at the centerpunch mark for making a 5 mm (3/16 inch) hole that allows gas or a gas/oil mixture to drain while shop towels absorb escaping oil. The second hole at the middle indentation in the tube should be drilled using the same 5 mm drill bit after creating the mark by centerpunch while protecting against oil spillage with shop towels. After removing the shock absorber from the vise position it horizontally above a drain pan while facing the holes downward to extract all oil from the tube by moving the rod through the tube.
