To replace the rear carrier bearings and rear u-joints on a Mid-Size Polaris Ranger, first, start by knocking out the roll pin on the front prop shaft and take the front bumper off. Take the right front tire off and take apart the hub assembly where you can remove the CV axle, doing the same on the driver's side. Next, move the differential to the side and loosen the two bolts on the carrier. Pull the shaft out the front and the rear part with the carrier will come out the bottom. Don't waste your money on the pillar-block style bearing carrier, just get a factory style. Pick up some 338 greaseable u-joints and simply complete the above instructions in reverse. You don’t have to mark the shaft, as Rangers have a master spline. This may sound a bit daunting for novice mechanics, but it's not as bad as it sounds. All you need is a 15mm and a big enough socket to go over the u-joint caps. A small sledge hammer is useful to have as well. You can replace the carrier bearing with the stock Polaris part, but we suggest the MOOG u-joints. They’re a bit of a pain to install but definitely worth it. While your Mid-Size is apart, you may as well replace the roll pin on the front diff input shaft with a bolt to make future replacements much easier. And when it comes to replacement parts for the driveline, we would advise avoiding anything stock. Companies like Sandcraft make front and rear driveline components for the Mid-Size Ranger that are at least three times stronger. If you have any fitment questions or need advice on the best replacement parts for the rear driveline of your Mid-Size ranger, don’t hesitate to give us a call or shoot us an email!
