[polaris man 4]

hello i have a 1999 zl and i have huge vibrations at 70 mph and up. i heard from a lot of people that this vibration can be caused by the jack shaft being bent i brought it to a machine shop and it was off by 1 thow but my disk brake was off by 20 thow, so i changed it and i still have vibrations. all so there is a brand new drive shaft and bearings. all though i did not change the bearings in the jack shaft i am not sure if it is that.

if u have any ideas please tell me thanks

did you by chance get it stuck sometime right before this started ? if you did i bet you have a bad spot on your belt.

Why did you replace the drive shaft? I would be looking a little closer at that especially at higher speeds it will give you a noticeable vibration if bent slightly.

any chance your clutches are out of alignment,,, if you took them apart and didnt get them back together right, that could cause your problems also,,,
