Common Use Case or Symptoms:

Use when the front axle has developed play or rock at its pivot, there's a knocking from the front end over bumps, or the front axle no longer oscillates smoothly — a worn axle case bushing lets the front axle shift on its pivot, which throws off steering feel and accelerates wear on the pivot pin and the axle case itself.

Why Choose Broken Tractor:

✅ Low-Cost Fix for Front-End Knock – a worn pivot bushing is a common and inexpensive cause of front axle play, far cheaper than the axle parts it protects
✅ Wide L, MX, and M-Series Coverage – one bushing spans the L4240 through M8200 4WD lineup
✅ Fast Shipping from a U.S.-Based Team – ready to ship from our U.S. warehouses
