Position cutout in hub towards rear parking brake shoe. Remove rear shoe spring cup washer, spring and inner cup washer. Remove upper parking brake shoe adjuster and connecting spring. Remove lower parking brake shoe connecting spring.
Remove fulcrum shaft nut. Remove cotter pin, hub nut and washer from end of axle shaft. Place thread protector on end of axle shaft. Mount hub puller on hub. Disconnect hub and carrier from axle shaft. Remove fulcrum shaft. Remove hub carrier.

Clean and inspect all parts. Replace parts as needed. Reverse disassembly procedure while noting the following: when installing inner bearing to hub carrier, install shim between bearing and hub.
Mount dial indicator on hub carrier with pointer resting on end of hub. Use 2 levers between hub and hub carrier, press hub outward. Note reading on dial indicator.
The difference between dial indicator readings, is preload of hub bearings. Adjust shim thickness to obtain preload.
Bearing Replacement (Fulcrum Pivot)
Place hub carrier in a vise. Using a drift, remove fulcrum shaft components. See Fig. 7. Fit extractor behind bearing race. Install slide hammer to extractor and remove bearing race. Loosen, but DO NOT remove, extractor cross bolt. Remove remaining bearing race in same manner.
Clean and inspect all parts. Replace parts as needed. Pack bearings with axle bearing grease. Install bearing and fully seat bearing races using handle and race installer.
Using equal thickness shims, obtain bearing preload. To reassemble, reverse disassembly procedure.
Installation
To install, reverse removal procedure. Tighten all bolts to specification.
