I have bought a 07 Honda Rancher 420 4x4 and when i bought it alot of stuff was wrong with it and didn't know it. Joints... Gears .... Bearings. My very first ride the rear end started to pop really bad and i was in a rush to make it home but didnt even get half way and the rear end went out so i had to ride home in front wheel drive. So i tore it apart to find out it was the pinon gear was gone. replaced that but i didn't changed none of the seals i know stupid. i put it all back together added fluid and everything was good, One of my hubs was gone last week i fixed that and went up the road i started to hear popping didnt know what it was so took it home check everything, everything looked good, so i said its gotta be the rear end, tried to drain the rear end nothing but nasty crap came out of it, tore it all back down the gears looks good, found out the front seal was leaking and didnt know it, I guess it pays off to check all fluids. Anywas now i need the housing where the pinon gear goes in at, because mine where the bearing goes in at where the pinon gear slids into is broke off, Thats why it was popping. Trying to find a rear end and not having to buy a bread new one or if i can buy a housing. Thanks for reading.
