Warn CJ AMC
20 Full Float Rear Axle Conversion
some info provided by
Warn Industries
Floating axles
eliminate the axle shaft having to support the weight of the
vehicle as well as hold the wheels on. Because of the high
yield strength of the WARN axle, you'll also find the
largest spline count possible, limited only by the
differential. The internal splined wheel hubs eliminate
bolts and are guaranteed never to loosen. Warn Industries
also includes spring loaded lipseals in the wheel hubs and
spindles. O-ring seals are used on the hub lock interface.
WARN full floater kits with internal mount wheel hubs are
now sold as a two part number system: a "foundation" kit and
then your choice of drive flanges or hublocks. Drive flanges
are designed for people who do not flat tow or who
experience excessive driveline backlash with a mechanical
locker.
The AMC 20 axle
found in most CJ's between 1976 and 1986 is a good axle once
it's major flaws are addressed. The 20 uses a
semi-floating 2 piece axleshafts. The outer hub
attaches to the inner axle through a "self made" spline/key
method. Excessive torque due to lockers and/or larger
tires can cause the key and splines to give way leaving the
vehicle un-driveable.
The Warn full
floater kit replaces the entire axle assembly with one
similar to the CJ front system. Each wheel gets two
bearings instead of one and high strength hubs or flanges
complete the outer assembly.
The warn kit is
essentially a bolt on system and can be installed by the do
it yourselfer.
