Fitment and Application Details
Compatible with 1989-1995 BMW 525i, front left upper; 1994-1995 BMW 530i, front left upper; 1994-1995 BMW 540i, front left upper; 1993 BMW 525iT, front left upper; 1989-1993 BMW 535i, front left upper; and 1991-1993 BMW M5, front left upper. This part number is 31121141097, and it cross-references Beck/Arnley 102-5103 for the same application.
The URO 31121141097 control arm is built to match OE control arm geometry, helping maintain proper wheel alignment and directional control after suspension service. The included ball joint uses a metal bearing and high-strength steel housing, while the black neoprene boot helps protect the joint from dust and water intrusion. This makes it a practical replacement for worn BMW front suspension components on E34 platform vehicles.
What This Part Helps Correct
- Front-end looseness or wandering steering
- Uneven tire wear caused by worn suspension geometry
- Clunking or play from a worn upper control arm
- Reduced braking stability during suspension load transfer
- Alignment issues after replacing front suspension parts
Installation Notes and Tips
Install in the front left upper position only. Verify the ball joint orientation during installation; the fitment notes specify that the ball joint faces down on listed applications. Because this arm is not adjustable, final alignment should be checked after installation to confirm proper suspension settings.
Quality Assurance
URO supplies this control arm with guaranteed fitment and a 24 month unlimited mileage warranty. The design uses high-strength alloy metal construction and OE-style geometry to support consistent suspension performance on BMW 525i, 530i, 540i, 525iT, 535i, and M5 models.
