When I built my D44 originally I had pulled the tubes out of a Chev axle and cut them down and put them into a Ford HP, one of the problems was that the cut down tubes did not have recesses for the axle shaft oil seals so my machine shop chucked the whole C into the lathe and made one, they did not do anything wrong as it fit the shoulder of the seal perfectly but it should have been deeper as the aftermarket chomoly's typically have longer splines cut.
So those of you that wheel with me know I am always leaking oil on that side and conversely always have water in that differential.
I had looked at it last year when I installed the Grizzly but still couldn't figure out how to lengthen the seating surface so when I pulled my front axle to fix it this weekend I went at it again. I could not find a hole saw the right size but with a surprisingly small amout of effort because of these great tools:
1. a deburr tool from my local welding shop $59 but worth every penny as it lasts for years so long as you don't abuse it
2. flapper wheels which are also fairly pricey but they are amazing as I can even shape weld with them.
3. Die grinders, they are as useful in building stuff as the welder and the plasma.
I was able to move the seal quite far inboard. Although it is not perfectly machined (it is a nice tight fit and sealed well) and I may consider doing this outboard to keep all the mud and dirt out of my outer tubes.
I was wondering when I was doing it that there was not much material going into the diff housing, apparently it was blowing out the end all over everything I had lying there. :banghead:
This is a pic of my mangled slinger. I have had this twice in a D30 and now twice in my D44's does anybody know what causes this?
