Front Passenger Lower Rearward Control Arm for BMW 525i/528i/530i

In this review of the TRQ front passenger lower rearward control arm, the bottom line is simple: this part is aimed at BMW owners who need a direct-fit replacement that closely matches the original equipment. It is best for DIY mechanics and professional installers seeking a pre-assembled aluminum control arm with an integrated ball joint that simplifies swap-outs on 1997-2003 BMW 5 series passenger sides. The single biggest reason to buy is the ready-to-install design that saves time and avoids modifications while maintaining proper suspension geometry.

Key Features

• Direct-fit replacement: Pre-assembled to match OE mounting points so installers do not have to modify the chassis or control linkage.
• Aluminum construction: Lightweight material reduces unsprung mass while preserving structural strength for the lower control arm position.
• Machined ball joint mount: Ensures accurate alignment of the ball joint for predictable steering and suspension behavior after installation.
• Included bushings: Comes with bushings installed to restore correct suspension compliance and reduce additional part sourcing.
• Wide compatibility: Lists multiple reference numbers to simplify identification for 1997-2000 528i and 2001-2003 525i and 530i passenger side replacements.

Who It's For

This control arm is for vehicle owners and mechanics working on BMW E39-era 5 series models who prefer a pre-assembled, direct-fit unit to speed up a lower control arm replacement. It is especially useful for those who value an aluminum arm that matches original mounting geometry and includes bushings so fewer parts are needed during the job.

Those who should look elsewhere are owners seeking an adjustable performance arm for alignment tuning or a version with a greaseable ball joint; this TRQ unit is not adjustable and the ball joint is not specified as greaseable. Also, if you need a left-side or upper arm, this passenger-side lower rearward arm will not fit.

Pros & Cons

Pros

• Direct-fit, pre-assembled design reduces installation time and potential fitment errors.
• Aluminum construction keeps weight down while maintaining strength for suspension mounting.
• Includes bushings and a machined ball joint mount to help restore correct handling and function.

Cons

• Ball joint durability has occasional complaints, so buyers should inspect joint condition on receipt and during installation.
