HD Switch Front Wheel Bushing-to-Bearing Conversion Kit — 3/4" Axle, Sealed Bearings for Husqvarna/Craftsman

HD Switch front wheel bushing-to-bearing conversion kit replaces worn bushing steering spindles with sealed bearings to reduce axle wear and eliminate routine greasing. This conversion kit is engineered by HD Switch to upgrade RH/LH front axle steering spindles—turning bushing-style hubs into durable bearing assemblies compatible with many Husqvarna, Craftsman, Poulan, Jonsered and RedMax lawn tractor models. The complete kit includes sealed bearings with steel trash seals, synthetic-formula grease, and all necessary wheel hardware to rebuild the spindle and restore smooth, low-maintenance front-wheel operation.

How does the conversion improve steering spindle longevity?

Replacing soft bushings with precision sealed bearings reduces metal-on-metal wear and keeps contaminants out of the bearing race. The included steel trash seals and synthetic grease resist grit and moisture so the spindle runs cooler and lasts longer under load.

• Sealed bearings block dirt and water from entering the bearing cavity.
• Steel trash seals provide an extra barrier for rough mowing conditions.
• Synthetic grease with wear-resistant additives maintains lubrication without frequent re-greasing.

What comes in the kit and what will I need to install it?

The package contains the bushing-to-bearing conversion components plus all wheel mounting hardware required to rebuild the steering spindle. Basic hand tools and a press or suitable driver for bearing installation are recommended for a secure, correct fit.

• Sealed bearings sized for 3/4" axles and 1 3/8" rim openings.
• Complete wheel hardware set to replace original fasteners.
• Installation requires common shop tools; a bearing press or driver is recommended.

Which mower models and part numbers does this kit fit?

This kit fits a wide range of Husqvarna, Craftsman, Poulan Pro and related models that originally used part numbers 596873701, 596873601 and equivalent OEM numbers listed. Confirm fit by comparing your axle and rim dimensions: 3/4" axle diameter and 1 3/8" rim hole size.

• Verify measurement: axle 3/4" and rim 1 3/8" before purchase.

Will this conversion reduce maintenance needs?

Yes—sealed bearings are pre-lubricated and eliminate the need for routine bushing greasing, lowering downtime and service frequency. While bearings are long-lasting, periodic inspection is still recommended to check for play or damage after heavy use.

• Pre-lubricated sealed bearings remove regular grease points.
• Reduces axle wear that occurs with traditional bushings.
• Inspect bearings annually or after severe operating conditions.

This conversion kit is for hobbyists, lawn care professionals, and DIY mechanics who want a durable, lower-maintenance steering spindle rebuild. Choose this HD Switch kit if you need a direct-fit upgrade for affected Husqvarna, Craftsman, Poulan and related models, prefer sealed-bearing reliability, and want a complete hardware set that replaces worn bushings and restores front-wheel performance.
