    Hey, are you still looking for a case spreader? I made one that I can lend it to you, no rush. Is on the heavy side, for the shipping, but the offer is on the table. Let me know if you want pics.

    A trac Lok is really not worth the effort.

    Thank's for your opinion ????? I got a Brand new , Never installed unit from a fellow member for ~ $200. I know it will serve the purpose.

    I've heard of diff. case spreader need. And, I like what jackdog posted. I simply don't understand the origin of this design. Why were differentials ever designed this way? Why didn't engineers simply design an adequate space (maybe only 1/4 inch bigger?) for removal/replacement without that need? Is a spreader tool only required for certain applications? Certainly not to discourage some enterprising parking lot thief (like a catalytic converter theft). Was it to force the average Joe to spend more money at the dealership?

    I also made one for my first rebuild of my D30. I needed up not needing it. The case and bearings will go in and out and the spreader tool didn't seem to make it any easier.

    After I built mine, I found easier to do it the way metalshaper does it: a couple of long pry bars and... voila! Fortunately, it only costed me time to build the spreader, otherwise I would have been :banghead:

    Thanks, Gent's ! ...... I think I'll be fine with my pry bars . It was an OEM option for my '75.

    Should I delete this 'WTB' ????

    Its for the preload on the bearings.

    I can usually pop them out with a long prybar but putting them back in usually requires some sort of spreading device.

    Thanks all. I've never done this before, so I looked at metalshapers video, .... I hadn't thought about the preload reason for a spreader. I actually thought the case and bearings simply wouldn't fit in or out of that big, giant hole, once the cover was removed! Haha, ... always learnin'.
    But, going back in requires a spreader? I thought metalshaper just eased it in without a spreader, with some persuading hammer taps. Hmmm, Well, I wanted to rebuild front and rear axles for my '56 '5' ... But, ... I am starting to get a bit gun shy with my limited tools and experience in an ill-equipped basement. Oh well, I figured it'd be a couple yrs before I'd be cruisin.

    I've never used a case spreader. I've always managed by setting the bearing races over the rollers, than canting them slightly as they enter the housing. I'm sure a spreader would make it easier, but it can be done without.

    Forgetting the shims are under the case bearings. Newer Dana's have the shim between race and housing. Makes it a little harder to get in. Easier to setup, but harder to get shim in...
