Product Overview

Loose steering, front-tire wander, clunking over rough ground, or uneven tread wear can come from worn tie-rod joints. Jack and support the axle safely, then check every joint, kingpin, wheel bearing, steering cylinder, and axle pivot before ordering.

Each tie rod transfers steering-cylinder movement to the wheel knuckle. The listed overall length is approximately 13.03 inches; compare thread direction, taper, stud size, grease provision, and length to the removed parts before installation.

Frequently Asked Questions

Q: Should both tie rods be replaced together? A: The set contains two. If one is worn, inspect both sides; replacing the pair can make final alignment and steering response more consistent.

Q: Will new tie rods fix every loose-steering complaint? A: No. Cylinder pins, kingpins, wheel bearings, axle pivots, and steering valves can also create play.

Q: How do I confirm this is the correct part? A: Match 128-4128, machine serial number, approximately 13.03-inch length, taper, stud diameter, thread size and direction, grease fitting, and axle arrangement.

Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
