Detailed Description

This Dorman suspension control arm is made for BMW rear suspension service where the rear right upper forward arm needs replacement. It uses a stamped steel body with a coated black finish and a press-in end 2 type, helping restore the original suspension geometry on vehicles such as the BMW 320i, BMW 328i, BMW 430i, and BMW 440i. The 520-176 is also cross-referenced to MOOG Chassis Products RK643544 for the same application.

Built with one rubber bushing already included, this control arm is a practical OE-style replacement for worn or damaged rear suspension components. The welded ball joint mounting type and threaded stud design match the intended service layout for the listed BMW fitments, including rear right upper forward applications across multiple 2 Series, 3 Series, and 4 Series models.

• Rear suspension clunking or knocking from worn control arm bushings
• Uneven tire wear caused by loose rear suspension geometry
• Excessive rear-end play or instability during cornering
• Suspension noise from a fatigued or bent control arm
• Alignment issues after rear suspension wear or component failure
