Today I have been trying to get the rear differential for an modern IRS in with my helper. Good grief Charlie Brown!!! I kid you not, I am bleeding from 6 different places after this battle. Looks like I lost a fight and I am not sure I did not.
I never seem to learn as I just kept hitting my head on the underside of the frame. Maybe each subsequent shot to the head just made it tougher to remember, not sure. The most memorable experience would be when I dropped the dif on my face. Real smooth like. Don't worry, I have never made a cent off my looks and I was not expecting to start anytime soon.
Eventually we got it up there but then had a heck of a time getting everything lined up. I currently have the two front bolts in and the rear passenger side bolt in. The rear driver side just does not seem to line up and I am not sure what I can possibly do with three bolts in. I think the mount may just be an 8th inch off or so. Not sure what to do at this point. Really don't want to bring the differential back down as I had such a hard time getting it up there to begin with.
Where the bolt goes into the differential is threaded. For now, I have another bolt, which is slightly narrower threaded in. The narrower bolt fit okay with the 1/8th inch misaligned gap and did thread in, however, it is not the right size bolt and it slightly undersized.
What do you guys think? I know I read that others found it to be a tight fit as well and EdwardB used the tapered bolts. I am worried that the mounts are about 1/8th inch too close together and no maneuvering is going to get all four holes aligned. I did try losing the three bolts that were in to get any play I could. No mater how I seem to arrange it, I can't seem to get both rear bolts in at the same time.
Should I got back to war or use the smaller bolt I have in there now and add on a good amount of Locktight. The narrower bolt is snug and does need to be screwed in and out in case that matters.
