9040H Front Wheel Bushing to Bearing Conversion Kit Compatible with Craftsman, Poulan, Husqvarna, Jonsered, Murray Lawn Mower Fits 532009040, 532124959, 91334, 491334MA, 5920H, 9040HR, 9040N

What It Is

This conversion kit replaces your lawn mower’s stock front wheel bushings with sealed ball bearings, reducing wheel wobble and friction. Designed for residential riding mowers and lawn tractors from Craftsman, Poulan, Husqvarna, Jonsered, and Murray.

Fitment & Compatibility

Before buying, confirm these three things:

• Original part numbers: Fits OEM replacements 532009040, 532124959, 91334, 491334MA, 5920H, 9040HR, 9040N. Cross-check your mower’s manual or old part.
• Axle diameter: Kit is for 5/8" axles (common on most Craftsman & Husqvarna tractors). Measure your front axle with a caliper – if it’s 1/2" or 3/4", this won’t fit.
• Wheel bore depth: The bearings are 1" wide. Ensure your wheel hub has at least 1" of depth to seat the bearing flush. Shallow hubs may require spacers (not included).

Model notes: Works on most 42" and 46" deck tractors from these brands, but always verify by axle size, not deck size.

Key Things to Know

• Installation difficulty: Moderate. Requires removing wheels, pressing out old bushings (or cutting them out), and pressing in the new bearings. A bench vise or bearing press tool helps – a hammer and socket can work but risks damaging the bearing.
• Durability: Sealed bearings last far longer than plastic bushings, especially on rough terrain. Expect 2-3 seasons before replacement.
• Common gotcha: The kit includes two bearings and two metal sleeves. Do not skip the sleeves – they protect the bearing inner race from axle wear. If your axle is rusty, clean it with sandpaper first.
• No grease needed: Bearings are pre-lubricated and sealed. Adding grease can blow out the seals.

Should You Buy It

If your mower’s front wheels wobble, squeak, or feel rough when spinning, this kit is a cheap, effective upgrade. Best for owners of 5/8" axle tractors who want smoother steering and longer wheel life. Avoid if you’re not comfortable pressing bearings – or budget for a shop to install it.
