Hi, I need some help! I am trying to remove a brake drum from my Class A
motorhome. I have a Chevrolet 454 engine, so I assume the rear end is GM.
There are (8) 1" nuts holding the tires (750 R16)on. There are 8 more
bolts (size 3/4") on the end of the shaft (about 6" from the drum). Brake
Drum is stamped Max Dia. 13.09. How do I get this drum off? It looks like
there is a spacer of somekind on the face of the drum. I tried a 10"
puller on BOTH sides of the motorhome and I cannot get the spacer or drum
to move? The thing I am calling a spacer is almost 2" deep and the wheel
studs pass right through it. It sits flush up against the Brake Drum and
the wheel studs stick out the other side appx. 2 1/2". I removed the (8)
3/4" bolts on the end and it appears that this is the axle. I only slid it
out a 1/2" and stopped. It looked like this had nothing to do with
removing the brake drum. So I replaced the (8) 3/4 bolts on the end plate.
Anybody have any ideas? Thanks, Rick
Hi, thanks for the quick response. I have a couple of other question,
before I remove the axle, is there any kind of differential shims or
spacers that I have to worry about when I pull the axle out? Also are
there any C-clips at the end of the axle? Should I go ahead and pull the
differential cover to or will it be ok just to remove and replace the
shafts? Thanks, Rick
You are working on a "full floating" rear axle. All you need
to do on this one is pull the axle shaft right out. Then you
should see a large nut on the threaded spindle that actually
holds the bearings, hub, and drum in place. There should be
a flat circular clip that is holding a small square piece of metal
in a groove in the spindle. You will also note that "that" square
piece fits in a groove that is formed by both the nut and the
spindle. This is what keeps the nut from backing out. Remove
the retaining clip, remove the square insert, and then you can
back off the nut. You are supposed to use a special socket
for that nut, but I always just use a round punch, fit the end
in one of the indentations in the outer rim of the nut, and then
use the reliefs on the inside of the hub to catch the shaft of the
punch and turn the whole drum assembly in order to back off
the nut. Once it's a couple of turns loose, you can back it off
by hand. Then just pull the drum and hub assembly right off.
