In search of help I have a 1995 trx 300 just noticed that only the front wheels are driving machine. after jacking it up rear wheels will move on there owne with no load on them. Is this the pinion and gear or could it be something else. I replaced the gear abought a year ago. My swing arm barrings have lots of play in them could this have something to do with it. Please help, Thanks alot:icon_question::icon_question:

Welcome to the forums.. It's possible you may have damaged the shaft drive or broke a U-joint

I got the Fill cover off on the diff: and I could see that the gear is not moving it does have a little viberation when I spin the tires. also not realy any noise I'm in the process of taking apart is their a way i can check the shaft drive and the U joint before I drop the rear end. Thanks to everyone who helps.

Thats what I said pooping noise. LOL

I was going to plow my driveway, I only made a couple of passes when I noticed that the rear end stoped working

 

[jrowe06]

almost sounds like the pinion gear might be stripped.

 

[batpro]

If it is the pinion gear whaut could be making it go? I put a new one in about a year ago. I know the swingarm barrings are shot could this have something to do with it. How hard is it to change those barrings?

 

[jrowe06]

I D K i've never changed swingarm bearings,sorry,some one on here will know.

 

[TRX2fiveO]

the swingarm bearing are not that bad just time consuming. a little drive train 101.......simple steps to follow engine turns the inputshaft which turns the gears in the tranny, as you shift the forks in the tranny slide the gears back and forth on the main shaft and intermediate shaft. the drive shaft is connected by U-joints to the tranny and the rear differential which consist of a ring gear and a pinion gear carrier bearings and a pinion bearing. kind of like an auto. well these were designed to have a weak point for a purpose..... that weak point being??? Class......ok i'll tell you. THE UNIVERSAL JOINTS.
But since these quads produce so much power to weight and torque you have the occasional input shaft spline strip or a ring and pinion chipping off teeth. Start with the obvious... listen to your machine know where the sound is coming from and not what is transferring sounds. and you will most likely find the culprit.
Check www.bikebandit in the OEM parts section for a break down of the rear-end.

Can I check if universal joint without removing the whole rear end

 

[TRX2fiveO]

Um Im not real sure but I doubt it some of these utility guys may know.

 

[batpro]

More help wanted?

 

[mud99]

I think you can loosen the clamp on the axle near engine and slide the boot back and see the universal.

 

[TRX2fiveO]

Yeah I think you are correct mud, and while the boot is off spin the rear wheels and see what happens, it the shaft dosen't turn you know to go to the rear or a bad U-joint. If it does turn the you probably have a bigger issue in the tranny.
