304 Stainless Steel Front Wheel Axle and Bearing Rebuild Kit 00278500 05400726 07145400 Exact Compatible with Ar-iens Ikon X XD Gravely ZT XL Zoom Zero Turn Mowers with Tough Steel Seals

What It Is

This is a complete front wheel axle and bearing rebuild kit for zero-turn mowers, specifically designed to replace worn or failed axles and bearings on Ar-iens Ikon, Ikon X, XD, Gravely ZT XL, and Zoom models. It uses 304 stainless steel for corrosion resistance and includes tough steel seals to keep debris out.

Fitment & Compatibility

Before buying, confirm your mower model and deck size: this kit fits Ar-iens Ikon (42" and 52"), Ikon X (42", 52", 60"), Ikon XD (52", 60"), Gravely ZT XL (42", 48", 52", 60"), and Zoom (all deck sizes). The OEM part numbers cross-reference to 00278500, 05400726, and 07145400. Measure your existing axle diameter and bearing bore—these are not universal for all zero-turn brands. If your mower uses a different spindle design (e.g., stamped steel vs. cast iron), this kit won’t fit. Aftermarket replacement; verify your mower’s year and serial number with the manufacturer if uncertain.

Key Things to Know

• Quality upgrade: 304 stainless steel resists rust far better than standard carbon steel axles, which is critical for front wheels exposed to moisture and grass clippings.
• Installation difficulty: Moderate—requires removing front wheels, pressing out old bearings, and pressing in new ones. A bearing puller and press (or bench vise) are recommended. Not a quick swap.
• Common gotcha: The steel seals are tough but can be damaged if you hammer them in crooked. Use a socket or bearing driver to seat them evenly.
• Only 2 reviews: The 5.0 rating is from a tiny sample—no long-term durability data is available yet. The stainless steel construction is a plus, but check for any fitment issues specific to your mower’s front axle bracket.

Should You Buy It

This kit is a solid choice if your Ar-iens or Gravely zero-turn’s front axle has rusted or the bearings are noisy, and you want a corrosion-resistant upgrade. It’s best for DIYers comfortable with bearing replacement and who prioritize longevity over a quick fix. If you need a drop-in replacement with no pressing required, look for a pre-assembled hub assembly instead.
