Expect roughly $600 to $1,200 per axle for front control arm replacement on an Audi A4, including parts and labor; replacing a single control arm typically runs about $300 to $700.
Prices vary with the specific arm, whether you use aftermarket or OEM parts, the shop's labor rate, and geographic location. Alignment is usually required after replacement and can add to the final bill.
Factors that influence price
Prices depend on the arm type (upper vs lower), whether you replace one side or both sides, and whether the parts are OEM or aftermarket. Additional costs, such as alignment, are common after suspension work.
- Front lower control arm (aftermarket): typically $60–$180 per arm
- Front lower control arm (OEM/Dealer): typically $150–$350 per arm
- Front upper control arm (aftermarket): typically $120–$260 per arm
- Front upper control arm (OEM/Dealer): typically $250–$450 per arm
- Ball joints included with the arm or replaced separately can add roughly $30–$150 per arm
Prices vary by model year and generation (B8/B9) and whether the dealer charges premium for OEM parts or advanced wear items.
Typical total costs by scenario
Below are broad estimates to help you plan, assuming a typical U.S. market where labor rates vary by region.
- One front arm replacement (parts + labor + alignment) with aftermarket parts: roughly $210–$705
- One front arm replacement (parts + labor + alignment) with OEM parts: roughly $300–$875
- Both front arms replaced on the same axle (aftermarket parts): roughly $420–$1,410
- Both front arms replaced on the same axle (OEM parts): roughly $600–$1,750
- All four front arms (both axles) with aftermarket parts: roughly $840–$2,820
- All four front arms (both axles) with OEM parts: roughly $1,200–$3,500
Note: These ranges include parts, labor, and alignment where applicable. Actual quotes can be higher if dealers or specialty shops charge premium, if there are damaged bushings, timing, or other components, or if the car requires additional work to safely re-align the suspension. Always request a written quote before authorizing work.
What to do next
To get a precise number for your specific Audi A4, contact local repair shops or Audi dealers for a diagnostic and written estimate. Have your VIN handy to confirm the correct arm part numbers, and ask whether the price includes an alignment after replacement. If you're considering OEM parts, ask about warranty coverage on the assemblies.
Summary
Replacing front control arms on an Audi A4 is a common maintenance item with costs that vary widely. Expect around $210–$705 per arm with aftermarket parts or $300–$875 per arm with OEM parts, including labor and alignment, and double those figures if you replace both arms on both sides. Always obtain multiple quotes and confirm whether alignment is included in the price.
