MERCEDES BENZ A-Klasse — What to know
The modern A-Class (W176, W177) is built on a front-wheel-drive platform shared with the CLA and B-Class. It is less expensive to repair than larger Mercedes-Benz models and has growing independent specialist coverage. The 4MATIC all-wheel-drive variant adds a Haldex rear coupling requiring periodic fluid service.
What is this repair?
Plain-English overview
Coil springs support the vehicle's weight and absorb road impacts; a broken or sagging spring causes one corner of the car to sit lower, affects handling and can cause the tyre to contact the body. Springs are typically replaced in pairs per axle.
