does anyone like there gov-lock? is there a way to rebuild it a little better? does it ever really lock up? mine is a 14bff and the gov-lock isnt working, I was going to weld it up but if the gov-lock can be made to lock then I'll just rebuild it
 
I have a Gov-Lock in my 14 bolt. In the mud or on the street where the truck is on a level surface it works great. But if it leans a lot to one side it will only work half the time. When it locks in though it seems solid from one side to the other.
 
i love it in my dd truck for traction and easy tire wear for street . but yes if hard core all the time full locker would be in it.
 
mine works, and its better than an open diff. id throw it out if i had something else besides an open, or weld it if it wasn't my DD.
 
i had one in my blazer- key word is HAD. while it was bone stock i left a red light and heard a loud boom and i felt it through the floor, my rear diff. was officially open after that. After looking at the axle- i discovered a crack on top the 10b housing the gov lock literally exploded and broke the housing in the process. over the years i have seen quiet a few gov locks go wrong so i would try something else if possible
 
My gov lok works fine when I'm on even ground where traction is nearly the same on both sides. It is probably worn out. I would definantly consider a brand new gov lok for my 14BFF if I was going to rebuild my rear end for some reason.

Short sub,

The gov lok in your 10B is weak like you mentioned, it's the same with a 12B also but they are much stouter in a 14BFF.
 
I've heard the 1 ton versions are pretty strong. I blew up my gov-lock in my 12 bolt this winter doing some high RPM wheel spin in snow. My diff is just open now. I'm switching in a 14 bolt this spring with a gov-lock. I really notice the difference now without the locker. When I spin, I spin in a straight line.... its not as fun.
 
Do you understand how they actually work?

I've not heard of a 14FF gov-lock blowing up. Of all three common GM diff sizes, the 14FF is the only one that doesn't seem to have problems.
 
The gov-lock works by "sensing" difference of wheel speed between the two axles. When the difference is great enough some sort of ratchet or something locks up the axles. This is a problem because the inertia of the tires creates alot of stress on parts by shockloading. 1/2 ton diffs just aren't up to the task generally if you get any wheelspeed going on.

They don't seem to grenade, but when I took mine apart it was no longer functional. The governor mechanism which has these gears n teeth n whatnot seem to strip out rather easily. Once the governor no longer works neither does the gov-lock, leaving you with an open diff. Mine is now welded, no more problems :D

Is the governor lock what is in my 2001 Yukon XL 4WD? If so, it doesn't work well. The wife got it stuck today in my grass lawn.

lol


I killed one from a 1 ton 14 bolt..but that can be exspected if I was behind the wheel:dunno:

:D


mine went BOOM

I had to drive home on the front shaft, in 2wd I could put it in gear and get out and watch my rear drivehaft spin:crazy:
 
I like mine... My daily driver (97 Z71 w/ 4" & 33's) has a gov in the rear, and I like well enough. Now, when I got the 14 & 60 for my K5, then yeah, no doubt a DL was going in the 14... I ended up getting a DL for the front too. But, for my DD, the gov gets it done.

My 14bff Gov-Loc came to me with the teeth stripped off. From looking at the design I can see where some wheel speed b4 engagement could easily kill those tiny little parts. Excellent concept, flawed execution.
 
I guess I just hadn't heard of the 14FF problems.

I can vouch for the 14SF being the same way...the small teeth just aren't a strong part, and never can be. Even a chip of metal running through those gears could very possibly strip a few teeth off, rendering it less than 100% effective.

It is certainly an excellent idea, just too bad they couldn't beef up the operating parts of it better. I have never had the chance to look at a 14FF, I just assumed that since they *seemed* to hold up better, that the design (due to the carrier) was different and thus stronger. Well, stronger being relative apparently. :)
 
I've blown up 2 14blt gov locks - 1 sf 1 ff. Same technique, lots of tire spin + sudden traction = grenaded gov lock
