Whether the offside rear shock absorber has a serious fluid leak or you are noticing small symptoms, it’s important to be aware of any sign that something is wrong. Here are some ways to discover if a shock absorber is leaking oil.
1. Oil Mist Residue On Car Shocks
The piston rod carries oil from the cylinder to the seal. If the seal is dry, the oil can seep out.
2. Oil On Car Shocks
Worn piston rod seals can be caused by excessive runtime, lots of stress, and driving in dirty conditions. When oil leaks, the damping force is also reduced.
3. Underbody Sealant On Car Shocks
If you see underbody sealant on the shocks, it was likely due to a simple misapplication. Remove it so you can get a better idea of what’s happening.
4. Worn Out Chrome Coating On Piston Rod
The chrome coating can wear out because of the misaligned attachment point or distortion of the damper. Not only will there be oil loss, but you might also notice a reduction in performance.

Most damage occurs during assembly, leading to a tear in the seal.
