Curing a possible On-Demand 4WD headache By Nick Nelson
UPGRADE 2015 RZR XP 1000
FRONT DIFF CARRIER
The 2015 model of the Polaris RZR XP 1000 comes with a plastic bearing carrier in the front differential that is proving to be
its weak link in racing and extreme-driving situations. The 2014 model year 1000s and even
the previous 900s came with metal carriers
that were pretty much worry-free. If the plastic
bearing carrier breaks, you will experience intermittent functioning four-wheel drive, as well as
an unpleasant, grumbling front-end noise. The
stock front carrier can be replaced for about
60 bucks, but we would highly recommend
upgrading to a hardened aluminum piece, like
the one from Black Rhino Performance, or you
can even order a billet OE Polaris one that is
used in the High Lifter Mud Edition XP 1000.
Black Rhino Performance’s aluminum carrier
is hardened for even further durability, and it
costs about $180. It can be installed with simple hand tools in about an hour and a half, and
it will be the last time you worry about your front
diff. Call them at (619) 561-5000 or check them
out at www.blackrhinoperformance.com.
Tools needed: Side cutters, ratchet or
impact, flat-blade screwdriver, 27mm, 19mm,
15mm sockets, 15mm wrench, zip-ties, floor
jack and jack stands. Starting with a clean machine, chock the rear wheels, jack the front end up off the ground
and safely secure with jack stands. Remove the front wheels with a 19mm socket.
Remove the outer front-axle cotter keys with a pair of side cutters, remove the
27mm castle nuts, the spring washer and the brake calipers. Tie the calipers
out of the way with zip-ties.
Remove the hub/rotor assembly from the spindle, then remove the upper ball-
joint retaining bolt, releasing the spindle from the ball joint.
