Need to know a description of parts assembly for the wheel bearing assembly and parts as they go into place. Mine does not have a locking ring between the nuts and I think it should( part numberif possible) and how much end play there should be in the axle shaft,mine seems to move in and out a lot.

the part # is a dana spicer kit 28068x it is usually stocked anywhere dana spicer is sold. the axle will move in and out alot about 3/8 inch for when it turns left to right it can move around and not pull the axle out of the carrier

later

Thanks FoothillsGuy; couldn't find any info here about my 70 4x4 the GM places here say its too old and they have no longer got the parts books. One place had but that page was missing, just my luck. Wheel bearing torque settings?

the 1970 dana 44 you have there is a one year only unit; it has open knuckles and drum brakes. every year prior had closed knuckles and drums, and every year after had open knuckles and discs. have you considered doing an axle swap to get front discs?
I know its on my list.

I am getting along fine with the old drums and they were new not to long ago so I think I'll just keep them for now.

Mr. grumpy, what rear end do you have and what gears did your 4wd come with? I'm looking at another c20 4wd w/ 4.10s. Thanks,

I hear you on the drums, mine are doing fine also. If you ever need front wheel cyclinders goto napa and get the ones for a 69 3/4 ton.

Mine adds up to a 4.10, got to put new crown bearings in, whole lot of fun there! If you come across a blue center cap in half decent shape please send my way.
