14 Bolts FF Detroit locker install

[78blazaer]

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.

I am pretty sure you can use the same detroit since it doesn't replace the carrier just the spider gears. As of torque spec's.....I don't know but if you have a haynes manual it might be in there?

i believe the caps are 150ft/lbs, check the 14b bible over on pirate

Thanks guys.. 135lbs of torque for the bearing caps according to 4x4pirate website.

I'll second the 135lbs spec. I just finished setting up my 5.13's- 135lbs according to the precision gear install book thingy.

It's much easier to find thicker 4.56 or 4.88 gears that will work on your existing carrier than it is to find the thin ones that fit the more-rare 4.56 carrier. The Detroit will fit into either carrier, but you'll most likely end up keeping the carrier that you have anyway.
