Here is a step by step 'how-to' for Lippert bearing repacking and drum brake adjustment. This is based on the Lippert Bearing Inspection and Maintenance manual and Brake Maintenance and Inspection Manual.
Figure 1-2 hours per wheel.
To get started, you'll need a set of seals (Lippert 122088- for 5200, 6k and 7k axles) I'd figure four cans of brake cleaner and 2-3 rolls of paper towels, a 16 oz tub of high quality lithium wheel bearing grease, as well as everything else in the picture
A stool and a couple fury helpers is optional
Jack a wheel up under the axle
and remove the wheel. Pry the dust cap loose. Push the tab down on the lock washer and remove the king nut, tab washer and bearing washer. Give the drum a couple pulls to help the outer bearing come out. Be careful not to let it drop. Wipe of excess grease and set in a cup of solvent.
Now pull the drum off the spindle. Use a seal puller or channel locks remove the old seal being careful not to pry on the bearings. This was a little tricky and took a few minutes of prying and wiggling to get it off. Wipe the old grease off the bearings and place in a cup of solvent.
While the bearings are soaking, use brake cleaner and paper towels to remove all the old grease, brake dust and grime from the drum, bearing cups and dust cover. Try to keep any grease off the brake pad contact area of the drum. An old toothbrush is helpful.
