Front Right Upper Control Arm with Ball Joint for 2006-09 E350

In this review the focus is a direct-fit replacement control arm for the front passenger side of select Mercedes-Benz E-Class models. The reviewer found this TRQ-style assembly to be a practical OE replacement for owners needing a one-for-one swap; it is especially suited to those who value a unit that arrives with bushings and a machined ball joint mount so installation matches the factory geometry. The bottom line: a competent, vehicle-specific replacement that balances fit, material quality and cost for routine suspension repairs.

Key Features

• Direct Fit: Designed as an OE replacement so it lines up with factory mounting points and reduces installation time compared with generic units.
• Aluminum Construction: The control arm material is aluminum, which lowers weight while maintaining the stiffness expected for upper control arms on E-Class chassis.
• Ball Joint Assembly: Comes with a machined ball joint mounting type that helps ensure correct steering geometry when installed.
• Includes Bushings: The assembly ships with bushings included so most installations do not require sourcing additional suspension components.
• Vehicle Specific Fitment: The listing includes check fitment details for compatibility with 2004-2009 E-Class passenger-side upper front applications to avoid ordering mistakes.

Who It's For

This control arm is aimed at Mercedes-Benz owners and independent mechanics who need a like-for-like passenger-side upper front replacement for 2004-2009 E320, E350, E500 and E550 4Matic models. It is a good choice for those repairing wear-related suspension play, replacing a failed ball joint, or restoring proper wheel alignment after a minor impact.

DIYers comfortable with front suspension work will appreciate the OE-style fit and included bushings, while shops benefit from the time saved. Those seeking an adjustable performance arm, a greaseable ball joint, or parts outside the specified model years should look for alternatives made for those specific needs.
