Rear axle assembly remove reinstall for honda trx300ex atv.?
Yes I can do it. What is your question?
It's usually polite to go back to your question and click the Edit button, so you can provide additional information as requested by the nice folks listed above me. There are often differences between model years that can cause a significant difference in the disassembly and reassembly of most any component. Now I'm going to take a wild guess on this one. I'm betting that you've got a damaged or missing seal on the left side of the axle housing, which has allowed water to get into the axle housing, which has caused rust and corrosion on the axle shaft, and now the splines on the axle shaft where it fits into the differential housing are now worn smooth, and the quad won't go anywhere when you hit the gas. Sound like your bike? You'll have to replace the axle shaft and the seal using the directions listed in Guardrail Jim's answer, unless you're too cheap to buy new parts, or you don't believe in repair shops or dealerships, in which case you can weld the axle to the differential gear. I don't recommend this, but I've done it more than once and they're still running just fine. Remove the axle shaft as listed in previous answer, remove differential housing from drive shaft, split differential housing, remove gear and install on shaft EXACTLY in the center of the damaged splines, weld in place, chuck into lathe to turn welds down so they don't rub against bearing, reassemble axle shaft and gear combination into the axle housing and differential housing at the same time, reattach to drive shaft, reattach right side brake assembly, use silicone around brand new seal on left end of axle housing (if you didn't get the axle exactly in the center of the splines and the seal won't install correctly).
