I had loud squeaking coming from my front bushings also, and I was able to remove the bushing bolts one at a time and grease the bolt and bushing. By removing them one at a time, you can get them back in prettly easily. My 300ex rear axle bearings just went out and destroyed my bearing carrier, rear disk hub, and a few other parts, so I wouldn't put off replacing them (I thought just one more ride would be OK). There are a lot of parts in the rear axle/carrier/bearing assembly, and the way it's put together is not obvious. I wouldn't even try to change the bearings without a manual of some kind (Haynes, or Chilton's or whatever). The axle lock nuts on the right side of the brake hub are left hand threaded, and you need a LARGE wrench (45mm or 1-3/4", and a 56 mm)to get them loose. It took me two weeks to even find a place I could buy a wrench that large (I tried a torch, and a pipe wrench first), and then I had to cut the axle lock nut off with a hacksaw anyway. www.servicehonda.com sells the larger wrench/tool for around $60 . By the way, you can see exploded diagrams in the parts sections of the web site at www.servicehonda.com also, they help a lot.

Good luck,

Do some research in the files, this has been talked about and answered many times in the past.
the major tools that you will need just to get the axle out is a 1 1/8 or 1 1/16 socket to get the hub nut off. A big pipe wrench or a hammer and chisel(this for someone with no big tools) for the axle nut. And the hardest part is a large pair of snap ring pliers for the brake backing plate. After that you can get the bearing carrier out. The trick that I learned about 2 years ago was to heat the carrier up and then the old bearing will come out very easy.
When you put the new bearing in, pop out the seals and fill them with water proof grease.
If you have never done trhis find help the first time. Best of luck.

go to the atv connection home page click on product reviews or sport zone. You will find an article on installing a durablue axle on a 400ex. It will be the same process for your 300ex except loosen the carrier bolts like you would for a chain adjustment after the axle is out. When they are eal loose you'll be able to wiggle and slide the carrier out. The bearings may ned to be pressed in and out. Any questions let me know
