1970 K10 front hub question

[old fart]

I have a bad thump in my front hub. I need to remove it for a visual inspection. Can anyone send or post me a picture of the front hub exploded? Or mabe tell me how to remove it. I have tools and am mechanically inclined but I just started to take it apart and have reached a point that I can't figure out what to remove next to get the thing to come off. Thanks in advance for any and all help!

Is this disk or drum?

did you take the lockouts off?

if so then you need to go to autozone and get a chevy spindle nut socket (pic below). $10 to buy or you can return it when done..

There are two of these nuts with a collar in between them. Once that's off your outer bearing comes off and the hub as well (if the brake caliper is off)

lockouts are off and calliper is off. I took the outer ring off and the c clip on the center of hub. I will get a socket tomorrow. Thanks

no problem, I had to do mine, pay attention to setting the bearing pre-load and locking the spindle nuts back down.

This is the other option for the spindle nuts but runs about $150, I passed on that one...

Well I got it off and everything looks ok. My problem is I get a thumping, banging noise when I am in 4WD under load. I had a 72 GMC 4X4 and this happened to it. It has been years but I thought it was the hub that stripped. I am guessing that if the hub is ok then it must be deeper. Do you think it could be something in the axel itself? Do I have to remove the spindle and yoke ? remove the cover and remove the short front axle? Could this problem be in that shaft, or could it just be bad UJOINTS? I guess when I take the spindle off I will see if the ujoints are bad before going farther.

remove the 6 nuts holding the spindle, there are needle bearings inside the spindle as well.

U-joints are cheap and you can pull the axle out after removing the spindle... no C-clips like in the rear axle. Could be u-joints or something in the carrier (bearings, etc.) or dirveshaft / TC I guess... hard to tell...

The spindle may not come off easily, I had to take a BFH and a piece of wood to it, then some assist with an air chisel....be careful on the bearings surfaces and the threads... It's a tight fit in the knuckle...

thanks I will tear into it in the morning.

Well I finally got around to pulling the front axle on the passenger side. That is the side that was making all the noise while in 4 wheel drive. It sounded like it was slipping in and out of 4 wheel drive while under load. This caused a loud continuous banging noise while under load. The splines on the axel look fine and the u-joints look new. I remember when I bought the truck last year the guy said he had put allot of money into the front and rear axles. Almost $2000. It also came with heavy duty drive shafts from a 4X4 shop. At this point I have it all apart and I hate to put it back together without fixing the problem. The issue is I do not know what to look at next. Could it be the warn lockout hub? Maybe it was not screwed in all the way? I am grabbing for straws here. I still have to put a clutch in it after I fix this problem. I need to get er done before the snow flies. I plow my driveway and my shop driveway with this beast.
Thanks for any help
