I saw a thread saying its good to have a grease fitting in your rear axle so you can grease your bearings, its a benifit so you dont have to tear the rear end apart all the time.

All I did was take the rear end apart, then drill a hole for the fitting(right near the brake) then screw it in, then cleaned the housing out so no metal shavings are in there to mess up the bearings, then put everything back together and then greased it up!

Its very easy to do.

 

I once owned a used 93 Blaster that someone had done that to.I took it apart once to check out how it was working,plenty of grease,no mud.I usually rode it in some serious mud/water.

 

Well thats good, at least I'll know I will have grease in there 100% of the time.
