Re: grinding ring gear teeth for locker install?
There was an article in 4WD & Sport Utility by Randy Lyman (Randy's Ring & Pinion) on the very subject. He said not only is it OK, but sometimes it is needed and won't affect the performance. I think I remember the cross shaft clearance being one time it could be needed, but the grinding was not across the whole tooth. However, if by removing the carrier, and removing the ring gear you can get the cross shaft in, by all means, that is what you need to do.
I'll look to see if I still have it, but I don't have scanner. Anyone with the article and a scanner?
I had a wrangler that the cross shaft on the Dana 30 wouldn't come out without removing it all. It was a pain, but grinding the ring gear would NOT have been the way to get it to work. I think you are up against the same thing. Just remember to put all shims back the same way. Mark the bearing caps to get them in the same way. Use lock tite on the ring gear bolts.
