Description
Product Overview
Service your Polaris 35mm rear wheel bearings the professional way — without removing the hub assembly. This purpose-built bearing greaser tool injects fresh grease directly into the bearing cavity through a standard zerk fitting, pushing old, contaminated grease out the opposite side in a complete flush. Designed for Polaris RZR, Ranger, Sportsman, and General models with 35mm rear bearings. A single bearing replacement costs $80-150 in parts plus 2-3 hours of labor. This tool pays for itself the first time you use it.
Key Features
-
35mm Precision Fit — CNC-machined for an exact, leak-free seal on Polaris 35mm rear wheel bearing hubs. Won't slip or spray grease during the injection process.
-
No Hub Removal Required — Jack up, remove the wheel and axle nut, slide the greaser over the bearing hub, and pump. No hub disassembly, no press work, no bearing removal. Complete service in 5-10 minutes per side.
-
Complete Grease Flush — The tool forces fresh grease through the bearing from one side while pushing old, contaminated grease (with water, mud, and metal particles) out the other side. True flush, not just a top-off.
-
CNC-Machined 6061-T6 Aluminum — Anodized for corrosion resistance and built to withstand repeated shop use. Includes O-ring seals and a standard grease gun zerk fitting.
-
Broad Polaris Compatibility — Fits all Polaris models using 35mm rear wheel bearings: RZR 800/900/1000/XP/Turbo/Pro (2008+), Ranger 500-1000 (2013+), Sportsman 500-1000 (2009+), General 1000 (2016+).

Why Choose This
Polaris rear wheel bearings are exposed to water, mud, sand, and extreme loads — and they're not cheap to replace. A single OEM bearing assembly costs $80-150, and installation requires a hydraulic press and 2-3 hours of labor. Regular greasing with this tool flushes out contaminants before they cause pitting and failure, easily doubling bearing service life. At $40, it pays for itself on the first bearing you save. Trail riders especially benefit — a quick grease job before a multi-day ride prevents the dreaded "bearing howl" 50 miles from the truck.

Frequently Asked Questions
Q: Will this work on my Polaris RZR 1000 XP?
A: Yes. The RZR 1000 XP and all RZR 1000 variants (including Turbo and Pro XP) use 35mm rear wheel bearings. This greaser fits all RZR 1000 models from 2014 to present.
Q: How often should I grease my rear wheel bearings?
A: Every 500 miles under normal riding conditions. After any significant water crossing or mud riding. Before and after multi-day trail rides. More frequent greasing = longer bearing life — grease is cheap, bearings are not.
Q: Does this work on front wheel bearings too?
A: No — this is specifically designed for 35mm rear wheel bearings. Front hubs on Polaris models use different bearing sizes and configurations that require a different greaser tool.
Q: Can I over-grease and damage the bearing seals?
A: No — the tool design allows excess grease to exit the opposite side of the bearing, flushing old grease out rather than building pressure. The bearing seals are designed to allow this controlled grease exit path.
Q: What type of grease should I use?
A: Use a high-quality NLGI #2 lithium-complex or synthetic grease rated for wheel bearings. Marine-grade grease is recommended if you frequently ride through water or in wet conditions. Avoid mixing grease types — if unsure, flush completely and start fresh.
Q: How do I know if my bearings are already too far gone?
A: If you hear grinding, feel roughness when rotating the hub by hand, or see rust-colored grease leaking from the seal, the bearing is already damaged. Greasing can't reverse existing pitting or spalling — but it can prevent it in healthy bearings.
