into the ring end (bushing first, then tube, with white grease works best). You will install them to the Jeep
in a similar manner as the originals using the original upper nut and lower bolt/nut. They key difference
is that in most cases (even with aftermarket wheels), you must reverse the mounting and place the links
on the inboard side of the bar-ends and axle tabs as shown in figure 20-2 rather than the original
orientation shown in figure 20-1 to allow the links to clear the tires.
For 3.5” systems attach the bottom of the links to the original hole in the tabs on the axle. For
4.5” systems using the optional bar-pin-spacers (included with all 4.5” systems), you must drill a new
hole 1.0” above the original. Failure to do this when using the shock spacers will result in bar/link
‘reversal’ and could damage several components!

Step 21: Reroute Rear Axle Vent Hose. To compensate for the added distance between the frame and
axle due to the new ‘lift height’, the hose can be rerouted to avoid overextending it. Pull the hose out of
its clip on the frame and pull it off from above the spring seat on the frame by pulling on it from outboard
of the passenger frame rail. Now run the hose through the small gap in the corner of the right-rear shock
bracket and back down to the fitting on the axle. Your new routing should look like figure 21-1

The rear (and overall) suspension installation is now complete except for final adjustments and torques.
You may now reinstall the new rear wheels/tires and if not using a vehicle lift, you may remove the
jackstands and let the Jeep rest on all four tires.
