welcome to the forums. jack the rear end up, put the motor in gear, try turning the rear wheels, if they move ?, then your ring gear splines are bad, as well as your axle splines, and hub splines, one ?..or all of these will stop power from getting to the rear end, and ground .

and check the out put shaft of the motor, u-joint splines, as well as rear drive shaft and splines .

Thank you, I believe the ring gear splines and axle splines are the problem, 10 years old and just worn out. almost no splines in the ring gear and axle splines
very worn out as well. I'm replacing the complete rear diff with a new unit and a new axle. It was actually cheaper than buying the complete differential versus buying the individual parts. I sure appreciate the help!

your welcome . I had to replace the ring gear, and pinion gear, all bearings, all seals, and one right rear brake side hub, on this '05 trx500fm project I am restoring, the PO had a lift kit on it, aggressive tires, they pretty much ruined the drive line for the rear end..lol. ring gear and pinion gear alone was over 200 bucks.

I just bought a harbor freight 20 ton shop press, walked out the door with it for 149 bucks !!, best money I ever spent lately...lol.

That's a good price, way more than that over here.

very good price, I've used it a few times, not sure how I got by all these years without one ??!!. very good for the cash, even if it is a harbor freight ?, it still works very well !, love it !.
