Buyer's checklist
What to check before buying a used control arm
- Inspect the arm for subtle bends, hairline cracks, or deep rust scale, comparing geometry carefully against your original unit.
- Examine the rubber bushings for dry rot, tearing, or separation from the metal casing, as worn bushings require pressing out before installation.
- Check integrated ball joints for boot tears and axial play; if non-replaceable, factor in the cost of a unit with a fresh ball joint.
- Verify material type (cast iron, stamped steel, or aluminum) and sway bar link mounting location, which can vary across sub-models and suspension packages.
