decent video. but, it would have been nice if they had done a good inspection of the bearings and races to show what defects look like. also, if you are not replacing brake pads, you can take the caliper and its retainer as a unit so you dont have to bleed the brakes. but then you need to know the tricks that go with doing that, such as removing 1/3 of the brake fluid from the resivoir first, using a wood tool to push the caliper piston back into the caliper to make it easy to reinstall. and then refilling the resivoir. this video shows another point of interest, that all 5 bolts that hold the hub to the disc must be equally tight, and not cross threaded. note he uses carb cleaner, same as brake cleaner to keep any grease off the rotor or pads, because grease there will make the brake useless. and this guy must have gone thru a box of gloves. if you do it his way with the calipers, then put a drain hose on the bleeder nipple to direct the brake fluid into a glass jar so it doesnt just splash all over the place. return used brake fluid to the place you bought it, just like oil or coolant. if they wont take it, find a mechanic who will. some states have laws about this, such as calif. some dont.
your truck has a dirt shield inboard of the hub assembly. to inspect the axel mount bolts this may have to come off. maybe not.
also check the wheel mount bolts to make sure they are tightly intalled in the hub. they can break sometimes or not be fully seated in the hub. you can put a bit of wood on the underside of the bare axel and see if it is loose by jacking it up and down a bit with a floor jack.
look up bearing failures if there are any on youtube to find out what bad bearings and failed races look like. hope you can solve this. wobbly wheels are very unsafe.
