Would be interested to hear your comments on how difficult it would be to replace the rear axles on a TRX 300 (2WD). I own one that I only drive about a week or two out of the year that the previous owner neglected and ran with loose hubs. I have since replaced the hubs with new ones and tightened the nuts with an impact wrench so that they are good and tight. However if the job isn't that bad or requires special Honda tools, it would be a nice way to spend some time with my Dad who lives out of state.

Thanks.

 

First off, being a dad, I think it is a great way to spend time with your father. When I was young, I spent a lot of time with my father working on cars. Now I am doing the same with my 6 year old. Of course at that age, I spend more time watching him, than getting work done.

But I recently had my rear axle out of my 250r. It was not that bad, and I did not require special tools, at least from Honda.

Once you have the hubs off, everything just unbolts off. The two hardest part where taking out the bearings and putting them back in. Search the forums here for tips, because some people have used a torch, oven and the freezer for easier time.

But if you come across a problem, use it to have you and your dad try and solve it together. Of course the first time I heard my father swear, was working on a car.

 

Mike,

Thanks for the reply. I replaced the axle bearing on the right or brake side with little difficulty. Of course Murphy's Law always says if one side is easy the other will be hell. In any case, will I need to break open the differential pumpkin in order to remove either of the axles?

Again, thanks for the input.

Sorry, I have only done straight axle quads. I am not sure if you need to crack the pumpkin or not.

My GUESS would be no, but better check the manual.

 

David-

Your 300 has a single, solid rear axle, not two half-axles. To replace it, it is not necessary to split or even remove the rear gear case. Simply remove both rear wheels and hubs. Loosen and remove the two axle retaining nuts (and o-ring) at the left side of the rear gear case and the two at the right side of the rear brake drum. Remove the rear brake cover (and o-ring), brake drum and brake panel, then slide the axle out from left to right. Carefully note the orientation of the original axle as it was installed . . . it is NOT symmetrical. If I remember correctly, the rings in the center of the axle that thrust against the bearings are of slightly different widths. Grease splines on new axle, slide in place, with proper orientation, from right to left, reinstall brake panel, brake drum and brake cover. Don’t forget o-rings. Apply Loctite to threads and reinstall axle retaining nuts. Finally reinstall hubs and wheels. Good Luck.

Thanks guys. Doesn't sound like the job will be bad at all. I can order a new axle for just over 100 bucks and will replace the left side bearing too since the right side was done a little over a year ago.

One final question if I might. Can we follow a rule of thumb when tightening the axle bearing nuts or should I use a torque wrench?

Again, thanks for the very useful tips.

 

Don't know what the specified torque is for those axle retaining nuts, but they need to be good and tight. I use a 15" crescent wrench and get them just as tight as I can with it.

its actually impossible to replace an axle. When an axle is worn badly you must discard the complete atv, and purchase a new one. Send your atv to me, i will dispose of it properly.

 

hay there this is wired i just replaced my axl of my 86 4rx 250r i used a torque wrench just to have it all the same but i tightined them as i plased rides 86 4trx and 86 250r atc
