In addition to installing aftermarket differentials or diffs from other RZR models in your machine, in many cases, a faulty component or constituent differential part is the culprit. Replacing the front differential Sprague with an aluminum one from a company like SATV, putting in new differential bearings, swapping out the diff seals, and exchanging the armature plate for a new one are all ways to save an old differential from the junkyard and extend its life -- and thereby saving you money. Regardless if you do the work or you take your rig to a dealer, it is important to use Locktite when installing the four front differential bolts that attach the diff to the cage of the RZR. And because most mechanics use air drivers, it’s not uncommon for them to strip the bolt threads when working on the front diff. You can check this by looking at the first half of the threads. If they appear kind of melted, they are likely stripped. Poor dealer service is always a challenge. However, if they don’t already, make sure your dealer records the mileage, hours, and other applicable stats on your RZR when you take it in to get work done. That way, you have a defensible argument should there be issues in the future.
