Yeah, your hub is stripped and your axle will be too. Either weld it on or replace the axle and hub.
If you weld the right hub, you can still change the brake shoes. You can slide the brake drum back enough to get to the brake shoes. You just can't remove the brake drum all the way off the axle.down side..you won't be able to remove your brake drum once you weld the hub on..sooo..keep this in mind for later brake work..if it was on your left side..you would not be able to remove and fix your rear differental once you welded the left hub on.OK -thanks guys. Welding the hub on the axle sounds like the easiest and cheapest fix. Any downside to this approach?
As long as you don't have trouble removing the brake drum, it isn't that hard. Most of the time the brake drum will be seized to the axle or the brake shoes will be hung inside the drum and it will be hard to get off.How difficult is it to remove the hubs and axle?
Check your axle bearings and seals in both sides of the diff and the axle bearing and seal in the brake backing plate (aluminum piece). Those bearings are a common problem with a Fourtrax 300. It's best to check them before removing the axle. Grab the ATV by the back cargo rack and shake it side to side and up and down and back and forth, anyway you can, while watching for any movement where the axle comes through the diff and the brake drum cover. If the bearings are bad, you will be able to see the axle move when you shake it. When you shake it up and down, pick it up off the ground and sit it back down while watching the axle. It's a lot easier if you have someone else do the lifting and shaking while you watch closely.OK - thanks. Any other parts besides the axle and hubs that I should replace while I have it all taken apart?
Yeah, the two in the diff, you will have to unbolt the diff and knock the bearing and seals out but it's easy. The pinion bearings are the ones that's hard to change. You have to have a special tool to remove the pinion shaft and it's hard to get the needle bearing out. Just changing the two bearings in each side of the diff is easy. That's why it's a good idea to replace the axle bearings at the first sign of movement, so it don't wear your gears and cause the pinion bearings to go out.Do I have disassembly the Diff to replace the axle bearings?
Yeah, the length of the splines and hubs are the only thing they changed on the axle. As long as the right hubs come with the axle, everything else is the same and will work.It looks like Honda changed the axle and hubs in '93 (made the splines longer?). Will everything else match up if I use this axle and hubs?
Yeah, that would me my guess.Do the longer splines of the 93-00 make it stronger (less likely to strip out)?
Yes, put grease on the splines, probably doesn't really matter what kind.OK - got the new parts and plan to put it back together this weekend. Just a few questions.
Should I grease the splines on the new axle? If so, do I just use axle grease, molybdenum, or something else?
That's great, glad you got it fixed!!Just got it back together Sat. Much improved acceleration and handling. Thanks for the help on this guys.
