The last few rides out feels like while under load climbing or when the suspension compresses hard hitting a jump the track is ratcheting. Any ideas? Only thing I looked at so far is the belt drive system no lugs missing off of that. Thanks
Help: Track rachet on 14' pro rmk and Speedo quit.

If the track started ratcheting and the speedo quit I would check the drive shaft bearing on the pto side. The problems may not be related, it could be just a loose track. The speedometer problem may be something totally different but most likely they are related.
You are supposed to run the PRO track TIGHT. With 10 lbs behind the rear arm the spec is 3/8"-1/2". There is no way the track can ratchet on the drivers if tensioned properly.
I would look closely at all of the driveline bearings. The PRO failure mode is for the shaft to spin inside the bearing race. This grinds the shaft down and causes play in the system. My buddy lost a jackshaft, it was moving around so much on the brake end the QD belt was skipping, he also thought the track was ratcheting.

Yeah track is right in spec if not a bit to tight. So now that you say it I'm thinking it might be the bearings. So if I rode it 150 miles like this I'm guessing ill need a new shaft too.?
Simple enough to check your driveshaft. Pull the 2ndary clutch, if the shaft has spun inside the bearing on that side it will be easy to see. On the Mag side check for a loose quickdrive belt. If the belt is loose that is a sign of the bearing being spun. Pull the drive and check it out. It is not all that uncommon to see this happen. My 2013 has spun a drive shaft and jackshaft. Warranty will pick it up! One thing to also keep in mind, track ratcheting has to be the no. 1 cause of quick drive belt failure!
If either shaft is spinning in the bearing, the shaft is out of spec. You can replace it or repair it. My buddy had his jackshaft welded and then turned down to spec. He has a had a few rides on it and it seems to work fine. Jackshafts were reportedly on backorder recently.
The bearings themselves rarely fail. It is poor machining tolerances from whoever makes the shafts for Polaris. The press fit is not tight enough to keep the shaft from turning in the race.
