The rear drivers side is making noise that sounds EXACTLY like a wheel bearing has gone bad. No Biggie I figured as I've replace the front wheel bearings allready.

I know the problem isn't the brakes as the rear shoes have been replaced a couple weeks ago.

I check my service manual and it doesnt mention anything about rear wheel bearings whatsoever.

Anyone have a write up ? Or know how to replace the rear wheel bearing ? Is there even a rear wheel bearing ?

Any help would be great.

Yes there is a real wheel bearing, this is the procedure from the FSM

REAR AXLE SHAFT & BEARING
Removal

1) Raise and support vehicle. Remove rear wheel and brake
drum. Remove brake shoes from backing plate. Disconnect parking brake
cable from backing plate.

2) Disconnect and plug brakeline at wheel cylinder. Remove
backing plate-to-axle housing nuts. Remove rear axle shaft with
backing plate from axle housing. Remove "O" ring from axle housing.

3) If replacing bearing and oil seal, remove snap ring from
rear axle shaft. See Fig. 1. Using press, press rear axle shaft from
backing plate. Remove retainer from rear axle shaft.

4) Remove oil seal from backing plate. Using press, press
bearing from backing plate. Install nuts on serration bolts on backing
plate. Using soft-faced hammer, tap serration bolts from backing
plate. Remove bearing case from backing plate.

5) If replacing oil seal in axle housing, using slide hammer,
pull oil seal from end of axle housing. Remove hub bolts and oil
deflector and gasket from rear axle shaft (if necessary).

6) Using dial indicator, check rear axle shaft runout at
center of rear axle shaft. Replace rear axle shaft if runout exceeds
.079" (2.00 mm).

7) Using dial indicator, check flange runout at end of flange
near wheel lug nut stud on rear axle shaft. Replace rear axle shaft if
flange runout exceeds .008" (.20 mm).

Installation

1) Install NEW oil seal in end of axle housing (if removed).
Apply grease on lip of oil seal. Install NEW gasket, oil deflector and
hub bolts on rear axle shaft (if removed).

I have what sounds like static, not exactly high pitched, but sounds like metal on metal coming from the truck's rear. Someone mentioned maybe the diff but when I took it to Protrux they said everything in there looked clean.

I've been suspecting wheel bearings but I can't tell...

So is the rear axle seal and wheel bearings items that go out hand in hand?
It appears that my rear axle seal is good but I don't know about the bearings?
