The car's shock absorber needs to be replaced if it is leaking oil. The replacement method is as follows: 1. Loosen the wheel nuts in a diagonal sequence; 2. Lift the car with a jack; 3. Remove all the wheel nuts in a diagonal sequence and take off the wheel; 4. Disassemble the brake caliper; 5. Remove the control arm fixing bolts and loosen the fixing nuts of the spring strut arm; 6. Open the engine hood, loosen the fixing nuts of the shock absorber on the car body, and remove the shock absorber for replacement. The shock absorber is used to suppress the oscillation when the spring rebounds after absorbing shocks and the impact from the road surface, to accelerate the attenuation of the frame and body vibration, and to improve the driving smoothness of the car.

















Last time my car's shock absorber was leaking oil, and it really worried me! The main reasons for oil leakage are aging oil seals or internal damage to the shock absorber. The most obvious symptoms are excessive bouncing when driving over bumps and sometimes severe body roll during turns. Don’t delay in such cases—oil leakage will worsen the damping effect, increase braking distance, and accelerate tire wear. I recommend first checking the severity of the leak: if it's just minor seepage, you can monitor it for two weeks; but if you see oil droplets or a large oil stain, head straight to the repair shop. When replacing shock absorbers, always change them in pairs, and remember to get a wheel alignment afterward. Never skimp on quality by using cheap parts—my neighbor installed a no-name brand, and it started leaking again in just three months.

Having worked in auto repair for over a decade, I've handled countless cases of shock absorber oil leakage. Common causes include aging and cracking of oil seals, piston rod wear, or deformation caused by strong impacts. When a shock absorber leaks and hydraulic oil decreases, the damping effect is directly compromised. Drivers may notice unstable vehicle body movement and excessive bumpiness when passing speed bumps. During inspection, focus on checking for oil stains on the shock absorber cylinder and observe the rebound when pressing down on the vehicle body. Minor seepage can be temporarily ignored, but severe leakage requires immediate replacement. Remember to always replace shock absorbers in pairs (left and right) to maintain consistent damping, otherwise uneven performance may cause vehicle drift. After replacement, it's recommended to inspect other suspension components to prevent chain-reaction damage.

Discovering that your car's shock absorber is leaking oil can be quite frustrating. Most leaks are caused by aging oil seals, which lose their sealing performance over time. The symptoms are particularly noticeable when driving, especially over speed bumps where the ride becomes excessively bumpy, and during turns where body roll is more pronounced. It's advisable to first assess the extent of the leak: if you can feel significant oil residue with your fingers, it's time to take action. Repair costs vary widely depending on the vehicle model, ranging from a few hundred yuan for economy cars to potentially over a thousand for luxury vehicles. I recommend replacing the entire shock absorber assembly outright, as simply replacing the oil seal often leads to recurring leaks. After replacement, be sure to check for uneven tire wear, as the leaking period may have caused misalignment. Regular checks on the shock absorber's condition can help avoid such unexpected issues.

Shock absorber oil leakage is no trivial matter, as I've personally experienced. I once noticed oil stains splattered on the inner side of the wheel rim, accompanied by clunking noises when going over speed bumps. A professional mechanic explained that oil leakage reduces the body's support force, leading not only to a bumpy ride but also potentially causing abnormal tire wear and suspension deformation. Minor seepage may allow for continued use for some time, but severe leakage necessitates immediate replacement. When replacing, it's advisable to opt for original equipment manufacturer (OEM) parts for better reliability. After replacement, remember to perform wheel balancing and four-wheel alignment; otherwise, steering wheel vibration or pulling may occur. In daily use, try to avoid large potholes and high-speed crossings over speed bumps to prolong the shock absorber's lifespan.

During last week's , the technician said my car's shock absorbers were leaking oil. He explained that oil leakage is mainly caused by aging internal oil seals, and long-term driving on rough roads accelerates the damage. The symptoms are quite obvious: increased body roll during cornering, more severe nose-diving when braking, and uneven tire wear. The treatment depends on the severity of the leakage—minor seepage can just be monitored, but severe leakage requires replacement. When replacing shock absorbers, it's recommended to replace them in pairs on the same axle, as replacing just one can affect balance. Nowadays, there are two types of new shock absorbers: hydraulic and electromagnetic. When replacing them, you can consult which model is suitable for your vehicle. For daily maintenance, remember to regularly inspect the shock absorbers—generally, checking every 50,000 kilometers is a safe bet.
