my '02 400ex for the past 2 months or so has been giving me trouble with the whole rear end. i ended up having to buy a new rear bearring carrier, where the axle goes through the rear swingarm. and latly either the axle nut keeps loosening up *fixed that i THINK* but once again, the rear end itself is loose, but i've only ridden it like 5-6x since everything went in brand new.. any help on, anything to check and make sure is tight etc. etc. PLEASE HELP!
thanks

 

Did you remember to reinstall the spacer that goes between the bearings,are you tightening the axle nut tight enough, jam nut,howare your swingarm bearings?

 

basicly all of that is good .. i checked most of that last night.. i'l double check it again when i go out today... in like an hr.

 

are you sure you didn't over tighten the axle nut. If overtightened it will eat the bearings fast.

 

how do i know if it is too tight? and how do i tighten it to the right "tightness" ??

 

Call the dealer. I just hand tighten mine then snug it with a pipe wrench but i have tappered bearings. I have a rad bearing carrier. I had one in my suzuki for 5 years with no problems so when I put my 400 together I bought one.$230 Complete

 

sweet.. thanks
