I am thinking of installing a detriot locker on my rear diff GM 10.5 14 bolts FF. Currently It has 4:10 gear ratio. Two questions: 1. Can I use the same detriot locker when I upgrade to lower gear ratio (i.e., 4:56 or 4:88). 2. How much should I torque the two bearing caps. I have been reading this article http://www.off-road.com/chevy/tech/detroit/ and It looks simple enough, I think I can do it. The only thing missing on the article is how much to torque the two bearing caps. Thanks in advance.
