Yes, the Mevotech Original Grade GS20335 is a complete Suspension Control Arm and Ball Joint Assembly. The ball joint is permanently integrated into the control arm, so you receive a ready-to-install unit that eliminates the need to press or rivet in a separate ball joint, saving installation time and labor compared to replacing the ball joint alone.

Yes, a professional wheel alignment is strongly recommended after replacing any control arm or ball joint assembly. Removing and reinstalling suspension components alters camber, caster, and toe angles, and skipping alignment can lead to rapid, uneven tire wear and poor handling, even if the new part installs in the same location as the old one.

This Mevotech GS20335 is designed for the Front Right Lower position. It is a single control arm assembly for the passenger side (right side) front lower suspension on select Buick, Cadillac, and Chevrolet vehicles, and you will need a separate left-side part if replacing both sides.

While you can replace only the failed side, many technicians recommend replacing both front lower control arms in pairs if both have similar mileage and wear. Control arms on the same axle experience the same road conditions and stress, so if one has worn bushings or a failed ball joint, the opposite side is often close behind, and replacing both avoids a second alignment and labor charge soon after.

Common failure symptoms include clunking or knocking sounds over bumps or when turning, steering wheel wander or loose steering feel, uneven or accelerated tire wear (especially on inner edges), and visible play when rocking the tire by hand. These signs indicate worn ball joints or deteriorated control arm bushings that compromise suspension geometry and safety.
