Frequently Asked Questions

What is included in a Case 580M front differential rebuild kit?

Our Case 4WD front differential carrier rebuild kits are assembled to service the differential carrier assembly. Contents vary by kit, so match the part number to your axle before ordering. If you are unsure which kit fits your 580M, our parts team can help confirm.

Does the ring and pinion kit fit both 580L and 580M backhoes?

The front axle ring and pinion kit covers 580L, 580L II, 580 SL, 580SL II, 580M, 580M II, 580M III, 580SM, 580SM II, and 580SM III, along with 570LXT and 570MXT. Because gear ratios differ, confirm your axle and part number before ordering.

What are the signs of a worn front differential on a Case backhoe?

Common symptoms include whining or howling from the front axle, play in the driveline, and leaking around the pinion seal. Worn pinion bearings, seals, or gears are typical causes. We carry the bearings, seals, gear kits, and hardware to service these issues.

Do you sell individual differential parts or only full kits?

Broken Tractor offers both. You can buy individual pieces like pinion bearings, seals, O-rings, thrust washers, lock washers, and spacers, or complete carrier rebuild and gear kits. Call (800) 909-7060 if you need help matching the right parts.
