GOV-lock to Detroit Locker upgrade

[domator]

I have CUCV with GM Corp. 10 bolt rear axle. This axle has gov-lock. I would like to change it for DetroitLocker. Am I going to have any problems with it ? I mean - should I find open differential instead of gov-locked for that installation ?

You need a open not gov-lock to install the detroit. I don't think you can install the detroit in place of gov-lock.

Why? I think Detroit comes with new carrier and whole differential. I think from my old axle I have to leave just axle shafts (case of course), bearings and that's all. Am I wrong ??

The 10-bolt rear axles are the weakest axle option out there. I personally would be worried about it breaking WITHOUT a locker. Adding a detroit is a bad idea, in my opinion.
Option 1: Wheel it gingerly until it breaks (it will) and be glad you didn't spend any money on it. Then, get a stronger axle.
Option 2: Ditch the axle now and install a stronger axle.

Yes, this opens up a can of worms such as not wanting to buy 8-lug wheels ($50 each, not a huge concern unless you want pretty wheels.) Also, have to use adaptor ujoint OR buy new driveshafts. It's worth it. Don't invest mnoney in 1/2 ton axles as you will regret it.

Just noticed you are in Poland. I have no ideas about how available bigger axles are.
If they are not available, be forewarned that your rear axle is very much so your weak link. Adding a locker will only decrease it's TTE (time to explode.)

I disagree, the the weekest point of the 10B is the gov-loc. If he replaces it w/ an aftermarket case it will be stronger. He still may break a shaft w/ 35s but the Detroit will be fine.

joker, that is only for a 14B, w/ a 10B and just about every other axle, except a 2 1/2 ton Rockwell, the whole case is replaced.

Dominator, you need to decide now if you are going to keep the 35s and 1/2 ton parts. If you will be staying w/ the 35" tires I would recomend the Detroit and maybe some new axle shafts. If you plan on going bigger I would not put any money into the 10B axle, you would be better off using a stronger assembly.

Looks like your right. It's the 14 bolt that does not interchange. Sorry about that. Do you think the detroit would handle ok on ice and snow ?

It will work great in snow. Ice will be a problem, though. When the locker locks, it causes the tires to turn at the same speed, possibly causing you to loose control. You will definately have to be more careful.

The gov-lock on all axles is replaced by the detroit locker except the 14bFF because it uses the existing carrier (that's why it's cheaper for the 14bFF /forums/images/graemlins/smile.gif)so yes you can replace it and you will get better/stronger performance, and if you only run 35"tires you should be fine.
