C. INSTALL THE TIRE CARRIER SPINDLE HOUSING —
MOST JEEP FRAMES WILL REQUIRE THE USE
OF SHIMS BETWEEN THE FRAME AND THE SPINDLE HOUSING FOR PROPER OPERATION
1. Install the Zerk Fitting into the Spindle Housing so that the Zerk is facing DOWN.
2. Temporarily install the spindle mount to the right rear frame rail using the two ½” bolts, washers,
flange nuts and backing plate provided. HAND TIGHTEN ONLY for now, making sure that everything is
snug but still loose enough to adjust the Spindle Housing.
3. Install the Spiral Cut Bronze Bushings into the Spindle Housing at this time. They are designed to
have a slight interference fit. Tapping them in with a block of wood is OK if necessary, BE SURE THEY
ARE SEATED FULLY. NEVER USE A METAL HAMMER.
4. Install a Bronze Washer all the way onto the Tire Carrier Spindle.
5. Insert the Tire Carrier into the Spindle Housing
6. On the bottom of the Spindle install the other Bronze Washer, steel Retention Disc and use the fine
thread 1/2x1” bolt and washer to firmly attach the Tire Carrier into the Spindle Housing. There is no
need to add grease or to install the O-rings at this time.
