Bad roads are not the only culprit in suspension failure. Why stabiliser links and shock absorbers wear out and how to extend their life.
Chassis repairs are usually not expensive, but MSG Equipment notes that poor roads are not the only cause. A modern suspension consists of arms, bushes, ball joints, shock absorbers, stabilisers and springs, each wearing at a different rate.
- Stabiliser links wear fastest; the article says replacement may be needed roughly every 20,000–40,000 km. Rough roads, sand and parking on slopes shorten their life.
- Shock absorbers suffer most in hot weather under heavy load on bad roads; the oil degrades over time and dirt build-up hampers heat dissipation and damages seals.
The article names road dirt and deep potholes as the dampers’ worst enemies, adding that careful driving and cleanliness extend their life.
