Rear Ends - Educate Me

The ford rear axles will loose the axle and wheel also if the bearing goes out. I've seen several along the road that way. A 454 and a 10 bolt with big tires is perfect for dissaster. Anything can be broke if you try hard enough.
 
I did not have to try very hard...:D
The 91 was stock with a 135hp 6.2 with stock tires and rims. I put the lift and big tires on after the rear blew as part of the 8 lug swap. If only the NBS trucks could be changed out so easily.

Actually I never had that problem, mostly with the Fords the tiny little 5 studs that held the tire on broke. Atleast GM used 6 lug abd bigger wheel studs. My 79 Bronco held up real good except I broke the rfont wheel studs a few times. finally drilled them out and used bigger ones. Had to drill the wheels too. What a PIA.
 
And none of that helps you when the jerk neighbor kid loosens all your lug nuts or removes them and you take off down the road. Probably a scenario that happens more often than wheel falling off from mechanical failure.

I have blown apart many g80s. They will not take much abuse at all and when they blow the pieces fall into the spiders and self destrcut and the wheel , axle and all, fall off. No thanks. Been there , done that.

Are the G8o's in you guys trucks the same as in the duramax equipped trucks?

Cause we put these things through hell at the drag strip with big HP ...and too many 1/4 mi. passes to count and they hold up pretty dang good.
 
Well, I am more referring to the 1/2 ton versions. I have no experience with the 3/4 or 1 ton. The 1/2 ones blow apart with ease, gimme a Detroit Locker anyday...
 
Just my two pieces of copper but the 9.5" 14SF in my '83 has over 500k miles on it, nothing major done to it. It's open (no G80), which sucks, but it spent most of it's time on the farm just working away, with regular maintenance.
 
Our old 84 plow truck lost a c clip with about 150k on the clock put in an auburn posi and never had anymore trouble.
 
I personally have heard that only the 10 bolt G80s grenanded, havent heard anything bad about the g80 in the 10.5" FF 14 bolt, but then again there isnt much wheeling going on here either.

also, I may be wrong, but I always understood the gov-lock as the g-80.
 
The G80 is a gov-lok. The flyweight system is refferred to as a governor arrangement, thus how it got the name gov-lok. The main failure point in ALL of the G80's is teh teeth on the engagement cross shaft as it carries all of the load to ramp in the lcutches and if you put to much power to them it can strip the teeth off of the cross shaft. In the 10.5" 14 bolt, it can crack the housing if your carrier bearings are loose as the Gov-lok in a 10.5" splits and is held together by through bolts. The 9.5" 14 bolt GOV-lok is pretty weak as well as it is just a bloated 10 bolt gov-lok basically.
