How do I know if my inner tie rod needs replacing?

Troubleshooting
Vehicle steering feels loose after replacement
Verify that the jam nut is torqued to manufacturer specifications and ensure the steering rack is not showing signs of internal play.
Steering wheel is off-center
This indicates the vehicle has not been professionally aligned. Schedule an alignment service immediately.
Clunking noise during turns
Check that the tie rod joint is properly seated and the locking nut is secure; also inspect the outer tie rod end for matching wear.

Setup, Compatibility & Care
To ensure safety and performance, installation should be performed by a qualified mechanic. Because this part dictates the wheel geometry, a full four-wheel alignment is mandatory immediately following the replacement to prevent premature tire degradation.
Compatibility Note: The QR3998S is engineered for specific Citroen, Peugeot, DS, and Vauxhall platforms. Always cross-reference the part number with your vehicle’s VIN before beginning the installation. Care should be taken to ensure the gaiter (steering rack boot) is inspected for tears during installation; a damaged boot can allow debris to enter the new joint and lead to premature failure.
