Is my driveshaft worn?

[Byam]

Update on these 2 TCats (Both have 280 Tunes in them since day 1 and lots of long studs):
Dealer (in southern MN) is going to warranty everything for both sleds (new track shafts, new bearings both sides, new seals both sides). Get this, he said he's never heard of this problem!! Really?!!
Shows you what a sheltered life they lead. All I can do is shake my head.

Could you flip the rotor over and find the right shim to put on spline right inside the outer snap ring? Just curious.

I laid next to my sled and was able to push my driveshaft up and down while everything was still together. That's how much my shaft was worn. I also had to split my caliper and use a puller to get my rotor off. The shaft wore so bad there was a metal ring wedged into the splines of the rotor. My original bearing was ok after 10000kms, but was repacked yearly. I'm sure it wore the race from the shaft spinning inside. I went with a japanese bearing to replace the OEM china one.

I just can't believe I didnt have any vibration.

How did you use a puller with this hollow shaft, what did you press off of?

I had a small piece of aluminum I put on the end of the shaft. Then I used a 3 claw puller, put some pressure on it and the rotor popped off.

three jaw puller , with the right size socket to fit o.d of the shaft.
I did it last night ill post a pic later

That's what I figured that you had to put something of correct size over the hole to press off of.

Here’s what I’m trying this time instead of buying a new axle.
My buddy is a great machinist so he turned down the worn part of the axle and made a sleeve to fit. He put it on hot and it shrank on nice when it cooled.
We made it a slight press fit instead of the loose slip fit of the stock factory shaft.
only problem is that while installing the brake caliber assembly I will need to drive the bearing on the shaft but that should not be an issue.

I’m hoping this is the fix.

That will work but keep in mind that you'll need a puller to get it off.
I faced the same issue when (long before Travis invented his wedgey thing) I dimpled the shaft and had to press bearing on. Also, used green loctite at same time so had to apply some heat to soften that while pulling housing off. Good news is - it worked! Bearing was tight, and shaft not spinning in bearing so that's the important part.

IMO, not quite as easy as using the BOP solution where you can take off an put back on as desired.
