Brand New Differential Bearing and Seal Kit. You will receive one differential kit to replace the rear differential kit on the following: 2001 2002 2003 2004 Honda Foreman Rubicon 500 TRX500FA 4x4, 2004 Honda Foreman Rubicon 500 TRX500FGA 4x4 GPScape. A repair sleeve for the needle bearing surface of the input shaft is included. A needle bearing failure in Honda differentials often causes damage to the input shaft. In those instances, the ring and pinion often need to be replaced. It is now possible to repair the worn input shaft bearing surface with our repair sleeve. The shaft must be machined to allow the repair sleeve to press fit onto the shaft. The machining operation should be handled by a competent machine shop only. We work in conjunction with manufacturers and distributors to acquire the best products at the best prices, which we pass on to you, our customers. All items are new and in usable condition and the most affordable aftermarket parts you will find online.
