Replacement Interval
Replacement is recommended every 80,000–100,000 km or when symptoms appear.
Always replace shock absorbers in pairs on the same axle — uneven wear causes the vehicle to pull to one side under braking.
Signs of Worn Shock Absorbers
- Body nose-dives under braking, bounces on bumps
- Knocking, squeaking or vague feeling through corners
- Increased stopping distance by 10–15%
- Uneven tyre wear (flat spots, cupping)
- Oil leaks visible on the shock absorber body
FAQ
Which shock absorbers should I choose for BMW 3 Series F30?
For standard use: Sachs Sachs 317 622 or Monroe Monroe 16780 — OE-level quality at a fair price. For improved handling: Bilstein Bilstein 33-189274.
Should shock absorbers always be replaced in pairs?
Yes — always replace both shock absorbers on the same axle. A difference in condition between left and right causes instability under braking and in corners.

Springs are replaced separately, only when visibly damaged (cracks, sagging, breakage). They are not replaced as routine preventive maintenance.
