So just bought a new jeep and im curious how to fix this front driveshaft yoke, do i need a whole new yoke or just the bearing, its loose and im able to pull it back and forth slightly, can someone point me to a video to fix it? All my differential fluid has leaked out from it too, is their a seal and a bearing there? do i have to drop the axle?

 

You basically need to pull the axle apart and put new bearings, shims, and seals in to fix it right. Search videos on that subject and you'll find a ton.
