Detailed Description

It is engineered to match OE control arm geometry, helping maintain proper wheel alignment, steering response, and braking stability after wear in the original suspension components. This part cross-references Dorman OE Solutions 520-734 for the same application.

What It Helps Resolve
- Loose or wandering steering feel
- Uneven tire wear from incorrect front suspension geometry
- Clunking or play from a worn lower control arm or ball joint
- Reduced braking stability under load
- Front-end alignment issues after suspension wear
Installation Notes and Tips
Verify the front right lower position before installation and compare the original arm geometry, ball joint style, and bushing layout. This control arm is not adjustable and uses a bolt-in ball joint with a threaded stud. Because the part is pre-greased and greaseable fittings are not included, no additional greasing point is provided. Always perform a professional wheel alignment after replacement.
Quality Assurance
URO backs this control arm with a 24 month unlimited mileage warranty. The design uses high-strength steel ball joint housing, metal bearing material, and a neoprene dust boot to support long-term service in BMW suspension applications.
