Genuine Mazda Inner Tie Rod / Steering Rack End • NE51-32-240

Genuine Mazda NE51-32-240 Inner Tie Rod / Steering Rack End

Replacement Genuine Mazda inner tie rod / steering rack end for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 / NC models with 1.8L and 2.0L petrol engines from 2005/2006 to 2015 listed in the compatibility table.

The inner tie rod attaches directly to the steering rack and connects it to the outer track rod end. It transfers steering movement from the rack while allowing the linkage to articulate as the front suspension and steering knuckle move.

Correct inner tie rod condition is essential for accurate steering response, secure steering linkage and maintaining the intended front wheel alignment.

The same component is used on the left-hand and right-hand sides of the steering rack. This listing supplies one Genuine Mazda inner tie rod for one side. Two are fitted per vehicle.

Replacement may be required where the inner ball-and-socket joint develops excessive free play, stiffness or corrosion, or where the rod or threaded section has become bent or damaged. Possible symptoms include knocking, vague steering, delayed road-wheel response, difficulty maintaining the front toe setting or uneven tyre wear.
