High-strength steel Outer Track Rod with precision-engineered ball joints for ISUZU NHR NKR 4JB1 - Direct OEM replacement

The Outer Track Rod (Outer Tie Rod) with OEM reference numbers 8-97107318-1 and 8971073181 is a verified direct-fit replacement for the ISUZU NHR and NKR series light-duty trucks equipped with the 4JB1 2.8L diesel engine. This critical steering component connects the steering rack to the steering knuckle on the wheels, allowing for precise movement of the wheels in response to steering input.

The track rod is an essential part of the vehicle's steering linkage system, responsible for translating rotational steering input into lateral wheel movement. A worn or damaged track rod can lead to excessive steering play, uneven tire wear, wandering on highways, clunking noises from the front suspension, and compromised vehicle control — particularly critical for commercial trucks operating under heavy loads.

This OE-spec replacement track rod is manufactured to meet or exceed original equipment standards, featuring high-strength steel construction with precision-engineered ball joints for smooth, reliable steering performance and long service life under demanding commercial operating conditions.

4. Use a ball joint separator (J-36831 or equivalent) to disconnect the outer track rod
5. Remove the old track rod from the vehicle
6. Compare the new track rod with the old unit — verify length and ball joint taper match
7. Install the new track rod — ensure correct orientation
8. Install and torque the ball joint nut to manufacturer specification
