The Stovebolt Site Forums The Parking Lot Big Bolts 66 gmc 2 ton 4x4 dump truck

was wondering if someone would know. the front hubs of the truck were the 4x4 axle goes in the hub the part that the wheel bolts to if that should be half full of oil or should it be dry

Hi and welcome to the site! Be sure to stop by the welcome wagon forum and introduce yourself and yell us a bit about your truck!

I am not sure on front hubs that big of a truck, on all my jeeps and my Suburban (all 1/2 ton axles though) you greased everything to keep it lubed but there was no gear oil in it.

I am sure someone will come along that is familiar with your model and year of truck.

the reason i thought it might need oil in the hub is it has a drain plug or filler plug in the hub

it very well could, I am not sure and do not want to steer you wrong! I am sure we'll hear from some of the other members in the next day or two. Happy New Year!

That 2 ton model should be the KV4000
The Wheel bearings and hub cavity should be packed with wheel bearing grease.

As well as the knuckle cavity, upper/lower king pins.

If you have oil in there you have a leaking axle tube seal and it's washed the
Grease out.

And Welcome.
