How Long Do Car Shock Absorbers Last?
2 Answers
Shock absorbers do not have a specific replacement cycle and should be replaced when they are damaged. Shock absorbers need to be replaced promptly if they show signs of oil leakage or physical damage. Damaged or leaking shock absorbers can become stiff, affecting driving comfort. Before replacing shock absorbers: Wheel alignment must be performed when replacing shock absorbers because if only the left shock absorber is replaced and the right one remains unchanged, the spring force of the two shock absorbers will be relatively uneven. Method for removing shock absorbers: First, remove the four screws and take off the mudguard. You can see the repaired AB glue on the mudguard. Loosen the two screws fixing the brake caliper and remove the caliper. Remove the plastic cover at the top of the shock absorber, slightly loosen the screw with a hex key, remove the two hex screws fixing the shock absorber, and take off the shock absorber.
As a veteran driver with over 20 years of experience, I'd say it's hard to pinpoint exactly how long shock absorbers last, but generally they're good for about 60,000 to 80,000 kilometers. My previous car, which was mainly driven on highways and city roads, didn't show noticeable bouncing over speed bumps until around 100,000 kilometers—after replacement, the ride became significantly more stable. However, if you frequently drive on rough roads or mountain paths, they might wear out severely by 40,000 to 50,000 kilometers; if you often take long-distance trips, their lifespan could be extended. The key is to watch for abnormal noises or noticeable body sagging, as these indicate aging shocks. During regular maintenance, technicians will inspect the suspension system—it's best not to delay replacements too long, as worn shocks can affect braking and handling safety, leading to costlier and more troublesome repairs later. Early prevention saves a lot of hassle.
