Detailed Description

This Dorman suspension control arm is precision-engineered and tested to replace the original equipment arm on the rear lower rearward position of select BMW X3 and BMW X4 vehicles. The steel, boxed design helps maintain structural integrity, while the straight shape and standard replacement grade support proper suspension alignment and rear-wheel control. Part number 526-561 is a direct-fit solution for BMW X3 and BMW X4 rear suspension service where the original arm has worn bushings or mounting wear.

This part cross-references Beck/Arnley 102-8126 for the same application.

Common Problems This Part Can Help Address

• Rear suspension clunking from worn control arm bushings
• Excessive rear wheel movement caused by a fatigued arm
• Uneven tire wear related to rear suspension looseness
• Alignment instability after suspension wear
• Noise or vibration from deteriorated rear lower rearward mounting points

Installation Notes and Tips

Install this control arm in the rear lower rearward position only on the listed BMW X3 and BMW X4 applications. Verify bushing and mounting-hole dimensions before installation, and inspect adjacent suspension components for wear that could affect alignment. Because the ball joint is not included, confirm the vehicle’s original suspension design before ordering. Professional alignment is recommended after replacement.
