GW 427

Frequently Asked Questions

Q: What are the equivalent part numbers for the GW 427 steer wheel axle?
A: The GW 427 is also sold as GW427, GP 427, and GP427. These designations represent the same precision-fit axle for standard steer wheel and bearing hub configurations. Cross-reference your parts list or equipment manual to confirm GW 427 compatibility before ordering a replacement. Different manufacturers may use GW or GP prefix; verify the trailing 427 specification matches your axle.

Q: How does the GW 427 differ from other steer wheel axles like the GW 426 or GW 430?
A: Each axle model (GW 426, GW 427, GW 428, GW 429, GW 430) has a different diameter, length, or bearing interface to fit specific pallet jack models. The GW 427 is precision-ground for standard steer wheel and bearing configurations; it is not interchangeable with the others. Fitting the wrong axle model will result in loose or binding wheels and unsafe steering. Always confirm your jack is designed for GW 427 before installation.

Q: What is the installation process for the GW 427 axle, and is it plug-and-play?
A: The GW 427 is plug-and-play if the steer wheel hubs and bearing assemblies are undamaged. Remove the old axle (cotter pin, washer, nut), slide out the wheel assembly, insert the new GW 427 axle fully into the bearing hubs, and reinstall the nut and cotter pin hand-tight first. Spin the wheel to ensure free rotation without binding. If resistance is felt, the axle may not be fully seated or the bearing hub may be worn. Do not force the wheel on; contact the bearing assembly. Tighten the nut only enough to prevent axial play while allowing smooth rotation.

Q: What symptoms indicate the GW 427 axle needs replacement?
A: Watch for hard steering or unresponsive turning, grinding or clicking sounds from the steer wheel assembly, visible lateral or vertical play in the wheel when the jack is lifted, or flat spots on the wheel that suggest the axle was bent and locked the wheel. A bent axle cannot be straightened. If steering effort increases or the wheel locks temporarily during turns, stop using the jack immediately; continued use risks load tipping. Replace the GW 427 axle and inspect the steer wheel hub for damage.

Q: Does the GW 427 require lubrication, and how often?
A: The GW 427 itself does not require lubrication; the axle is hardened steel and does not wear appreciably. However, the bearing hubs on either end of the axle must be kept clean and lightly lubricated to prevent corrosion and binding. Apply a light oil or lithium grease to the bearing hub every 3 to 6 months, depending on environmental moisture and use frequency. Do not over-grease; excess lubricant attracts dirt and accelerates wear. Wipe away any dirt buildup around the bearing hubs before lubrication.
