Metal Shavings in rear end

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

Thanks for the quick reply. I drove it around 20 mins. Hope I havnt caused to much damage... Could that be the cause of water in my diff oil?
ok I will tear it apart tomarrow and give an update. Thanks for the info.
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 $602 bux.
Yeh the old final drive lasted 12 years lol so yeh I hope this one holds up for a while. My next question is about the front axle and cv joints. I put a 2 inch lift and a set of vamp EDLs. Now with the added flex on the front axle I hear it make a poping sound every once in a while when turning sharp. One thing is I beleive I need to re-grease the boots but Ive never done it before. Is it difficult to do? What kind of grease do I get? and how do i remove the bands from the boots? If someone has some instructions or mabye some pictured steps that would be great.
Thanks for the replies. I prices front axles and they are quite expensive. Like 270$ 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.
Haha yeh it seems any work I do to this four wheeler at the end of the day I turn out black. I think I'll be alright lol.
lol ok i have both front shafts out. Im not sure how you tell wether or not the cv joints are bad or not but they both move fine without and hangups or anything. Before I pulled anything off I grabbed the shaft and pulled it in every direction and there was no play on either side. I took a few pictures. I did find some bearings that were completly shot. Im hoping this is what is causing my poping type sound.

Ok i toor into the front differential and it is perfect. We had the axles replaced by the honda shop mabye a lil over a year back so Im guessing the bearing and everything were replaced also because they look brand new. I dont feel like the cv joints are bad but i need to fix that boot. Ill replace the nuckle bareings and see if that stops the noise.
Well everything is put back together and the locker is in place. Y'all had me worried lol but it turned out not bad at all. Only time I feel it's hard to turn Is when I'm in reverse but even still it's not bad. I replaced the nuckel bearings and seals and the piping sound I had is gone. Every once in a while when I turn as sharp as it will go I hear a very light pop but it doesn't sound like I need to worry about it. As far as the boot I took one clamp off and tried to get it to pop back out but it wouldn't. The Honda shop said sometimes that happens? I went ahead and regreased them anyways. I'm rdy to take it out now. Thanks for all the help. I appreciate it.

The boots had probably been like that too long to spring back to shape.

My Grizzly has the pushbutton locker and when I lock it, it's pretty hard to steer, but I guess it's a lot heavier than the 300. Glad it worked out for you.
Yeh that's what I figure on heavy atvs it would prolly make it a lot harder.
