What causes front struts to leak?

Leaking front struts are usually caused by old parts. With time, the seals on the struts can become brittle, preventing them from keeping fluid within the system. So inspect the struts for any broken seals or deterioration.

Can a strut on a car leak oil?

Sometimes struts will show signs of leaking a very small amount, but will be OK for many more thousands of miles without replacement. Struts have a seal where the strut rod runs though and can leak minimal amounts of oil around the seal without being dangerous. My guess would be 75%+ of the cars on the road will show some signs of leakage.

Why is oil leaking from my shock strut?

Every strut and shock contains oil. Over time the shock’s piston seal can wear slightly, allowing some oil to “weep” past the piston seal. This leaking strut or shock will have a small moist area on the exterior of the unit down from the piston seal area.
