Husqvarna 587738904 Steering Shaft Kit

What It Is

The Husqvarna 587738904 Steering Shaft Kit is an OEM replacement assembly that connects the steering wheel to the front axle on zero-turn and lawn tractors. It’s designed for Husqvarna models with a worn or broken steering shaft, restoring precise turning and eliminating play.

Fitment & Compatibility

• Check your model number: This kit fits select Husqvarna zero-turn mowers (e.g., Z242F, Z254, Z4218, Z4623) and some lawn tractors (e.g., TS138, TS248). Verify your machine’s model number on the frame tag or owner’s manual.
• Deck size not relevant: Compatibility is based on chassis/steering column design, not cutting deck width. Measure the existing shaft length and diameter (typically 5/8” or 3/4”) to confirm.
• OEM only: This is a genuine Husqvarna part. Aftermarket alternatives may require modifications—stick with OEM for guaranteed fit.
• Measure before ordering: The kit includes the shaft, bushings, and hardware. If your old shaft is bent or sheared, compare total length (approx. 12-14 inches) to ensure match.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, sockets, possibly a puller) and a few hours. Some models require removing the dash or fuel tank for access.
• Common gotcha: The steering wheel nut can be stubborn—use penetrating oil and a puller to avoid stripping. Also, note the shaft orientation (keyway or spline alignment) before removal.
• Quality: OEM construction is steel with corrosion-resistant coating. Expect tight tolerances and no slop if installed correctly.
• Warranty: Typically includes a 90-day Husqvarna warranty. Keep your receipt and packaging.

Should You Buy It

If your Husqvarna mower has loose, stiff, or unresponsive steering and you’ve confirmed model fit, this kit is the right fix. It’s a direct OEM replacement with strong reviews, and it’s cheaper than replacing the entire steering column. Best for DIYers comfortable with moderate mechanical work.
