GENERAL NOTES:

These instructions are also available on our website; www.synergymfg.com. Check the website before
you begin for any updated instructions and additional photos for your reference.

The installation of the inner axle sleeves requires removal of wheels, brakes, axle shafts and axle
housing assembly.
 Installation of the sleeves requires drilling ½” holes at various places on the axle housing.

A competent welder is needed for completing the plug welds and circular welds around the axle housing
tube for proper installation.

It is recommended to remove the axle housing completely; this will make drilling and welding much
easier.

It is not necessary to remove the differential and gears or even drain the oil. Just be careful to not let
metal chips in the differential housing when drilling the holes for the plug welds. Be careful to keep the
housing level so gear oil does not leak out.
