D44 case spreader?

I have a D44 that I am putting into the rear of my '92 XJ. The D44 has a blown (really blown, the case had little bearing cylinders inside when I opened it and the pinion can be turned without turning the ring gear) pinion bearing. I need to remove and replace the carrier. I've searched NAXJA forums and there seems to be two opinions about case spreaders: they are necessary, and that they aren't necessary and may actually warp the case. Which is correct?

Also, I can build a case spreader if I can figure out how to attach it to the case. It appears that the best way is, at each side, to use two of the bolts that hold the rear cover to bolt the spreader arm. There is also a drilled hole in the cover sealing surface, directly in line with the axle and between the bolts. Is this hole designed to receive a pin from the spreader? How do spreaders attach to the D44?

Thanks!
 
I've built several axles (30s, 44s, 60s) and have never a case spreader. I usually just pry the carrier out with a prybar or come-along.

You see those 2 large holes at the sides of the pumpkin? Here you put in the "noses! from the housing spreader. Be careful not to spread it too much because this will destroy the housing. First try to remove it without a spreader.

Usually from 44s and up you need to use a housing spreader to set the correct bearing preload on the carrier bearings. This is really essential the bigger the axles get and the more power they receive from a strong engine and/or low gearing.
 
I will second the need for a case spreader. while I do have one, I use it on a weekly basis.I even needed it on a TJ this weekend. you might be able to cheat on a front axle and . but not on a rear. and when i say cheat, I mean that you have no choice.
 
just get two pry bars out and a BFF (big fawkin friend) and pry it out
 
The only time I've used a spreader was for installing ARB's where the shims go on the outside of the bearings. If you're wanting the spreader for pulling the case out then try a couple of faster and easier methods. Place a rag between the pinion and ring gear and turn the pinion, it'll pop right out. You can also put a box end wrench on one of the ring gear bolts, turn the pinion 'til the wrench contacts the housing,prys itself out. Be careful either way, the case can be heavy and akward if you're laying under the vehicle. TC
