    I read the article on grinding a dana 60 to fit 15" 8 lug rims. Would the same grinding be required on a dana 44 3/4 ton?
    I scored a gm14 bolt and dana 44 off a 76 chevy to swap in my 91 k5. I pulled the rear cover on the 14 bolt. I think it has a limited slip?? its kind of a cone shape coming thru the ring? would that be a factory limited slip? and does it require special gear oil?
    Thank

    Yes you still have to grind the 3/4 ton D44 or 10 bolt. It is not as extensive as the D60 though. It depends on your backspacing. 4.25 you have to grind a bit. 3.75 some and 2.75 many people dont have to grind at all:D

    That depends. I like the 4.25 beause it's less stress on the ball joints, and wheel bearings, but you have to grind more. The 2.75 you don't have to grind at all I believe, but that is more stress just hanging off the end of your axle. With 33's it's prolly not that big of a deal. If you are like anybody here the 33's will only be a stepping stone:D The 3.75 would be a happy medium. Give it a little wider stance, and you should only have to grind a little bit.

    This is a 3.75 BS 15x10 rim and a 12.5 wide tire. I have 4.25 BS rims now and they sit in just a hair more about .5" to be exact:D

    I'll 2nd what Brian said. Here is a pic of what and where I had to grind to fit 15 X10's with 4.25" BS on my 8-lug D44.

    I had to grind on the caliper and grind/reshape the caliper bracket.
