Singapore car repair guide

Mercedes E-Class: Knocking sound from front suspension over bumps

If you are seeing this symptom in Singapore, use this as a pre-workshop checklist. The goal is to identify the likely root cause, avoid replacing the wrong part, and know the fair repair range before approving work.

Fair SG range
$400–$600
Red-flag quote
$2,000+
Likely fix
Lower control arm bushing replacement (front)

What this usually means

This is 80% likely to be the LOWER CONTROL ARM bushings ($400-600 each side), NOT the absorber. Mercedes agent often quotes $2,000+ for the full absorber replacement. Demand visible fluid leak proof on the absorber before agreeing to replace it. Bushings wear out around 80,000 km — replacement is straightforward.

What to ask the workshop before approving repair

  • • Show the diagnostic fault codes.
  • • Show photo/video proof of the failed part.
  • • Give an itemised quote for parts and labour.
  • • Explain why cheaper common fixes were ruled out.

This is not a final diagnosis. It is a money-saving checklist before you go workshop.
