FAQ

How do I know my RZR 800 rear differential bearings are bad?

A whine or growl that rises with speed, play in the input or output shafts, or gear oil leaking around the seals are the usual signs. Metal in the drained gear oil is another warning.

What comes in the kit?

All Balls lists one O-ring, three seals, four tapered bearings and 12 washers per kit.

Which models does it fit?

All Balls lists Polaris RZR 4 800 (2010-2014); Polaris RZR 800 (2008-2014); Polaris RZR S 800 (2009-2014).

Is installation difficult?

The differential comes out of the machine and is split so the bearings can be pressed and the seals driven in. This is a shop-level job; follow your service manual and refill with the correct gear oil. All Balls does not publish an install sheet for this kit.

Which position does it fit?

All Balls lists this kit for the rear differential on the machines it covers.

Should I buy the full kit or just seals?

If the differential only leaks and the bearings are quiet and tight, the All Balls seal-only kit may be enough. If there is noise or play, the bearings need replacing and this full kit covers both.
