Product Details

The Atlantic Automotive Enterprises Remanufactured Electronic Rack and Pinion Complete is processed through inspection, disassembly, cleaning, shot-peening, and replacement of wear components before testing. The remanufacturing process also includes fault clearing, repeated cycling, and vehicle simulation testing to verify function and restore OE performance characteristics. For Ram 1500 Classic steering repair, ER5121 provides a practical replacement path when the original electric rack shows wear, noise, or inconsistent assist.

This part cross-references Monroe Shocks & Struts (e.g., 68230030AA, 68230030AB) for the same application.

Common Uses

• Steering play or looseness caused by rack wear
• Electric assist irregularities or loss of assist
• Internal steering noise from worn rack components
• Replacement after contamination or internal fault
• Restoration of steering response in Ram 1500 Classic service work

Installation Notes

Verify fitment by year, make, model, and steering configuration before installation. Transfer or replace related steering components as needed during service, and follow factory procedures for alignment and system calibration after installation. ER5121 is supplied without mounting hardware.
