Rear Spindle Bearing Spanner

What is the correct spanner to get and where to get it to disassemble and assemble the rear brake drum? I have searched but, I am unable to find the information.

Which truck?

TM 9-2320-289-20, Section 8-5, page 8-10.

CTA Tool # 4177 spanner Wheel bearing lock nut socket $34.95.

Mine came off with just ah flat head screw driver. You mite try that first before shelling out the $35.00..

How did you properly set the bearing preload with your screwdriver?

Pound head of torque of course. You didn't know?

50 foot pounds, then loosen to align the key, that 50 foot pounds is to clear thick grease. If you know what you are doing, it isn't hard with improvised tools. I made my own wrench for the axles, took just a few minutes.

So, it's like foot pounds, but with a hammer... Ah...

What is the conversion from ft/lbs to ham/lbs?

Pound head. Pound the head of the screw device.

I bought the spanner from NAPA. Thanks for the input.

Well for starters it wasn't that tight to begin with. Which is why I was able to easily tap it out with the screw driver in the first place. Secondly I've always done bearing preload by feel rather then a torque wrench. A torque wrench can't feel if the wheel is too loose or too tight. Just my opinion...

And you are absolutely correct. Feel is far more important than torque, for one the bearings and their races are hardened steel, the threads on the nut and axle housing have **** near ZERO deflection from 50 foot pounds, considering area of thread engagement and cross sectional areas.
Now, the belt and suspender crowd that have lost feeling in their extremities feel the joy of using a $500 digital torque wrench because it covers up their lack of knowledge about what they are doing. Cargo cultism.

That 50 pound feet of torque assures the roller elements have displaced the layer of grease applied to the races and what is properly mashed into the cages, assuring a line contact of each roller to the mating races. Backing off to the next index slot means there is now space for grease with minimal slop. These are NOT spring preload bearings (like kingpin bushings in the upper knuckle of the Dana 60 axle).
