Mopar 4782643AD Shock-Suspension

You can Select Your Vehicle to check if 4782643AD fits your vehicle.

These vehicle models are equipped with shock absorber/coil spring assemblies. It is possible to replace the shocks or springs individually but the unit will have to be disassembled by a qualified repair shop with the proper equipment. This will add considerable cost to the project. You can compare the cost of replacing the complete assemblies yourself to the cost of replacing individual components (with the help of a shop). Removal: Remove the cap on the shock tower and remove the fasteners that attach the upper end of the shock to the frame. Loosen the front wheel lug nuts. Raise the front of the vehicle and support it securely on jackstands. Remove the front wheels. Disconnect the stabilizer bar link from the shock assembly. Remove the fasteners attaching the lower end of the shock absorber to the lower control arm. Pull down on the lower control arm and remove the shock absorber towards the rear of the vehicle. Inspect the shock absorber for leaking fluid, dents, cracks and other damage. Inspect the coil spring for chips and cracks which could cause premature failure. Inspect the spring seats for hardness and general deterioration. If any of the components of the assembly are worn or damaged, have the unit serviced by a qualified repair shop or replace it. Installation: Installation is the reverse of removal. Tighten the mounting fasteners. Note: Raise the lower control arm with a floor jack to simulate normal ride height before lightening lower shock absorber mounting fasteners. Tighten the wheel lug nuts.

The steering linkage and suspension components should be checked periodically. Worn or damaged suspension and steering linkage components can result in excessive and abnormal tire wear, poor ride quality and vehicle handling, and reduced fuel economy. To check the shock absorbers, park the vehicle on level ground, turn off the engine, and set the parking brake. Push down at one corner of the vehicle and release it, noting the movement of the body. It should stop moving and come to rest in a level position within one or two bounces. If the vehicle continues to move up and down or fails to return to its original position, a worn or weak shock absorber is likely the reason. Repeat this check at each of the three remaining corners of the vehicle. Raise the vehicle and support it securely on jack stands to check the shock absorbers for evidence of fluid leakage. A light film of fluid is not a cause for concern, but if leakage is noted, the shocks should be replaced as a set. Also, check the shocks to ensure they are securely mounted and undamaged, and inspect the upper mounts for damage and wear. For the steering and suspension check, visually inspect the components for damage and distortion, including seals, boots, bushings, and leaks. Examine the bushings where the control arms meet the chassis, the tie-rod ends, the ball joints, and the steering gear boots. Clean the lower end of the steering knuckle and have an assistant move the wheel in and out while checking for movement at the steering knuckle-to-control arm balljoint. If there is any movement, the suspension balljoint(s) must be replaced. Grasp each front tire at the front and rear edges, push in at the front, pull out at the rear, and feel for play in the steering system components. If any free play is noted, check the idler arm and the tie-rod ends for looseness. Lastly, for the CV Boot check, inspect the boots for tears, cracks, and loose clamps. If there is any evidence of cracks or leaking lubricant, the boots must be replaced.

Start by raising the rear of the vehicle and supporting it securely on jackstands. Remove the wheel and support the spring link with a floor jack. Remove the fasteners attaching the upper end of the shock absorber to the frame and then remove the fasteners at the lower end.
