I recently bought a 1988 300 fourtrax and need to rebuild the rearend. Can anybody help?

 

I rebuilt the rearend in mine, What exactly is wrong with yours? Does it need a new ring and pinion or just bearings?

 

I have it tore down and it needs bearings and ring and pinion. The pinion gear has teeth broke off. I'm having a problem getting the pinion gear out of the housing. I can't break the nut loose. How did you get yours off?

 

put something against the pinion and use air on it then ull need a special tool to remove retainer ring .The big problem is removeing rear pinion bearing i cut them out they dont make a puller for it!!! Sometimes id have to put alittle heat to the houseing to remove retainer nut.

 

Appreciate it I'm going to try it this afternoon. Where did you buy your parts?
