Driveshaft rattles

I don't have a part number for the new thing they're offering. Let us know once you get it.

I've got a rattle that I thought was the front floor. I didin't look too carefully. Are all the rtvs needing them?

I've been trying to find out if it's a problem in a certain range of serial #'s.

Whoodle,

You'll know if it's your driveshaft by putting your foot on the shaft and apply pressure while it's in neutral. If the noise and vibration stops it's you shaft. /forums/images/graemlins/grin.gif

Here is my temporary solution for the drive shaft rattle on my RTV. Shoved two lenghts of heavy-wall vinyl tubing on each side of the u/joint cross. The tubes don't even come close to touching the u-joint seals. Works great! /forums/images/graemlins/cool.gif Can hardly wait to see what new design Kubota comes up with to fix this problem. Oh, the tubing is 1/2 inch ID.

I checked my machine today and the yoke that goes over the splined output shaft certainly wiggles a fair amount. It doesn't seem to rattle, but I only have about 35 hours. The deep snow this winter really put a damper on my use. The tolerances on my other machines with such splines are certainly tighter. Should I just plan on replacement? I can't really see how those pipes are alieviating the problem.

I'd get ready to make the trip. I believe Kubota will come out with a product recall. Too many people are starting to have this problem. I may be wrong but I believe it will come to that. Just my $.02 /forums/images/graemlins/grin.gif

I checked mine the other day. The rear U joint is somwwhat loose where it connects to the tranny. A replacement has been ordered (I'm going off warrantee within 30 days).

Although I don't know/think it would really be an issue over the long haul, I did apply pressure to the shaft and there was "noise" so I guess it doesn't hurt to replace.

BTW, has anyone replaced this themselves? If so, what did you do to get the driveshaft off?

Brian,

I looked in the Service Manual and there isn't any procedure listed to remove the U joint per se.

I did find a procedure to remove the shaft in order to work on the front differential - I've included an attachment - maybe this is the way to remove.

Thanks George,

That approach looks like it should do it. I need to replace the rear universal/yoke. It looks like I just need to reverse the direction of sliding in step 2.
