Product Details

BBB Industries Reman Rack and Pinion line focuses on remanufactured steering gear assemblies built to match the original hydraulic layout and mounting dimensions. Part number 309-0123 is specified for Mitsubishi Diamante vehicles from 1997 through 2004 with power steering, making it a direct-fit option for steering rack replacement on this platform. This part cross-references Monroe Shocks & Struts (e.g., 19320836) for the same application.

Common Repair Applications

• Steering play or looseness in the Mitsubishi Diamante
• Hydraulic fluid leaks from the rack housing or ports
• Worn inner tie rod joints affecting steering response
• Binding, rough steering, or inconsistent wheel return
• Excessive steering effort in power steering-equipped vehicles

Installation Notes

Verify hydraulic port thread sizes, mounting-hole spacing, and input shaft dimensions before installation. This rack uses two mounting holes and is configured for hydraulic steering systems, so the vehicle must be equipped with power steering. After installation, bleed the power steering system and perform a front-end alignment.

Quality Assurance

As a remanufactured steering assembly from BBB Industries, this rack and pinion is processed for reuse in a steering application that matches the original Mitsubishi Diamante fitment profile. Confirm part number 309-0123 against the vehicle’s steering configuration before ordering.
