2nd Gen Non-Engine/Transmission Installing Locker in Dana 80...

[wildmanben]

So I got the parts and going to put it in. Its too tight, needs to be shimmed. Order a shim kit and it comes with the shims that go between the bearings and the carrier. Is that the only way to shim these? I was hoping for shims that go between the bearing cups and the case. So how do I set this up without wrecking a bunch of bearings? Or can you buy the larger shims somewhere? I cant even get both of the cast selective shims in, so will it be ok if the bearing cups go right to the housing without them? #@$%!

Dana 70/80 carrier bearings are set with shims between the carrier and bearing. You can buy what are called dummy bearings which are a bearing that is a few thousanths oversized to slip on and off the carrier to ease in shimming. What I have done is take a set of good used bearings and use a die grinder with a flapper wheel and grind out the inside race of the bearing until you get a slip fit.

This is typical with Dana axles. To set it up right you need to make a set of "setup bearings" by grinding the I. D. so it sildes on/off the carrier so you can set up the correct backlash. Do a search for Yukon gear install this will have all the info you need.

I did a search and read about using slip bearing to get it set right, but will a used bearing require more shims that a new bearing set?

If you use a "Good Set" of bearings you might see . 001"-. 003" difference. Its not going to be enough to throw off your setting. You can leave out a real thin shim If I remember right the thinnest shims in the kit are . 003".

Got it together. Using the old bearings works really good. Only took 7 trys... . Oh well. Its in and works.
