Detailed Description

This Dorman suspension control arm is designed for the rear upper suspension location on the 2001-2008 Jaguar X-Type. The arm uses a bent steel design with a press-in ball joint mounting type and rubber bushings to restore the original suspension geometry at the rear upper position. Dorman 524-978 is a practical replacement choice when servicing worn suspension components on the Jaguar X-Type, especially when the original arm shows play, corrosion, or bushing deterioration.

The powder-coated finish helps protect the arm surface, while the forged/cast construction supports the demands of everyday suspension movement. This part cross-references Delphi TC6822 for the same application.

What It Helps Address

• Rear suspension looseness or excess movement
• Clunking or knocking from worn bushings
• Uneven tire wear related to rear suspension wear
• Loss of rear alignment stability
• Corrosion or fatigue in the original control arm

Installation Notes and Tips

Install this control arm in the rear upper suspension position on the specified Jaguar X-Type applications. Because the ball joint is not installed and the mounting hardware is not included, verify all related service parts before beginning the repair. After installation, a professional wheel alignment is recommended to confirm suspension geometry and tire wear performance. Use the part number 524-978 to confirm application details before ordering.

Quality Assurance

Dorman states that this control arm is precision-engineered and rigorously tested to serve as a reliable replacement for the original equipment on specific vehicles. The design and material selection are focused on consistent fit and serviceable suspension performance for Jaguar X-Type applications.
