Hello. Im new to the forums as far as just registering but I've been reading over different things here for along time. I have just recently started fixing up my 1998 honda 300 fourtrax 4x4. I replaced all the seals and bearings on the rear end, put a 2 inch lift on it and 27" tires. I felt that everything went well so I tested it a couple of days ago and had no problems. I went thrue several decent mud holes but nothing serious. After the ride I checked it over and found that the left side axle nuts near the final drive were both loose. I went and checked the rear diff fluid and found that it was bad murky brown so I must have not placed a seal right or something i guess. I stuck my finger down in there and found metal shavings. I will tear it down tom morning and see how much damage ive done. Could the axle nuts being loose cause the shavings? Any help would be great. Thanks

Hello and welcome to the forums ..... if the axle housing nuts are loose it could cause the bearings to wear and thus the ring gear and pinion could wear

Welcome to the forums. I agree with Submarine. When you fix it back again and tighten the axle nuts, I would put locktite on them.

It may have let the axle move back and forth and let the water in.

Welp im 600$ broker but i feal it was a good choice. Took everything apart and found my pinion was a little toor up. Bearings were out in it and the bushing at the back was completly demolished. I priced the parts at the honda shop and they started to rack up. A guy that I've been dealing with for the past few weeks helped me out on the price of the whole rear end complete assembly new. So I ended up replacing the whole rear end for $602 bux.

Glad you got it fixed. You should be good for a long time, now, with a new final drive. Just keep your eye on the axle bearings. When they wear a little, they let the axle move back and forth and that's what causes the ring and pinion to wear. It's best to replace the axle bearings as soon as you see any play in them. It's a lot cheaper than replacing the whole final drive.

Yeh the old final drive lasted 12 years lol so yeh I hope this one holds up for a while. My next question is about the front axle and cv joints. I put a 2 inch lift and a set of vamp EDLs. Now with the added flex on the front axle I hear it make a poping sound every once in a while when turning sharp. One thing is I beleive I need to re-grease the boots but Ive never done it before. Is it difficult to do? What kind of grease do I get? and how do i remove the bands from the boots? If someone has some instructions or mabye some pictured steps that would be great.

after you get the front wheels and hubs off..remove the knuckle from the a-arms...now would be a good time to repack both ends of the cv joints...with a sharp tug/pull...pull the axle out of the front differental..it might take a few pulls..but it will just pop out..you may loose some front differental oil...soo..remember to re-fill it after your done..once you pull the axle out...with a small screwdriver..bend the metal tabs up and out of the keeper thats around the band..it's just crimped down around the band..< it's best just to remove just one band < the big end >..slide the boot back far enough to inspect the cv joint..repack..slide it back on if the cv joint is good..most times..if you hear a poping sound when turning..the cv joints are bad...this will require a complete tear down of them..this can get alittle tricky..lol..one end of the cv joint is held together with a snap ring that sits down inside the cv joint..remove it..then it should just pull out..sorry..i don't remember which end won't come out of the cv joint..i do know one end does..oh..make sure that you don't take both sides out..and put them in on the wrong side !

I agree with that. I hate messing with the CV joints. I had just about rather buy new axles than to repack them. LOL.

Thanks for the replies. I prices front axles and they are quite expensive. Like 270$ a piece. Right now I've invested over a grand in the old 300 in the last 3 weeks so I'm not looking forward to buying axles. I'm going to tear the front end down Tom morning in hopes of just replacing parts. I've never don't this before so any help would be great. I know I will have questions tomorrow :happy: I have the Honda 300 service Manuel so that should help.

Yeah, those axles are expensive.

If you have the service manual, you should be fine. That's the messiest grease I've ever seen.
