Re-assembling 4x4 Sierra rear hubs
Could someone help me please:
Using a hub puller I've split my 4x4 Sierra rear disk hubs so as to get them out from the sub frame and put them in the upright.
My problem now is getting the three parts back together again. I was experimenting so I haven't put new bearings in (yet) but they only way I
can press the three parts back together again is to put the back of the hub on the table and bash it as it's so stiff 
I can't believe this is the right way to go about it- especially as one will now not spin.
Can anyone tell me what I'm doing wrong please! When I've bought new bearings I don't want to risk knackering them!
Thanks,
James

James, you should have basically three parts - the part that the cv joint from the drive shaft bolt to and has a long spined section on it followed by
a thread, the middle section of upright, hub and within that bearings and seals on either side, and finally what I'll call the drive flange, god
knows whether that's the right term, which has a machined section with the corresponding internal splines to those on the first section and a
plain machine exterior section with two steps. The first narrower step goes through the bearings, and the second wider section goes into the oil seal.
All that's left then is to put the first section into the splines in the assembly you just created and press the two together using whatever
method you please (rubber hammer worked for me!) until you have enough thread exposed on the wheel side of the assembly to put the hub nut on and use
that to pull the whole thing tight (really tight) together. A bit of a clean and some grease would probably ease the whole process.
Hope this helps.

In the absence of a press, you could always put the stub axles in the freezer, and put the bearings in a really warm place, though not hot enough to
melt any seals (if they have seals). When the components are suitably cold/warm, they'll simply push together.
It worked on my motorcrosser when I was 9, and has worked dozens of times since.
Cheers, Rorty.

It's a while since I took mine apart but it sounds as if you are having trouble fitting the hub into the bearing carrier. Have you removed the
inner seal and bearing from the carrier ? The outer bearing inner race should be quite a tight fit onto the hub shaft. As said before cooling the
shaft and warming the bearing will ease fitting. You could also use a suitably sized tube to tap down the inner race. With the bearing outer races,
the outer bearing rollers and outer bearing seal in the carrier fit the hub. Now fit the inner bearing rollers and inner race and seal. Hope all these
inners and outers make sense, do a dry run with the old bearings. The only time I used a puller on my rear hubs was to extract them from the
driveshaft.
