Getting ready for a new locker here is the case spreader i built.Flat bar is 2"x1" with 1 1/4" tubing weld to the ends and 1" acme thread. .

I have literally rebuild hundreds of Danas and only tried the case spreader 1 time just to try it and threw it back in the tool heap at the truck shop, never saw the benefit of using a spreader on Danas, neither did the full time gear builders.

YH, can you give some pics on your install? would be interesting..

I used one once as well, and next time I will try without it. I had put an indicator on the case to see if it moved, and it moved about .01thou and I still had to tap hammer the set in the case. I was also worried about breaking the bolts that held it to the case.

Looks good. My 1955 dana case spreader fits from 27 to 70 series. I always use it. How else are you going to get carrier bearing preload?

give it as many shims as you can and still stuff it in there, that's how
