Re: OUCH! My rear end hurts
gov posi.. never heard of them. the pic did seem weird though. This is all that i've ever seen of a reg posi.
Only reason i ask is i've seen 2 or 3 guys stumble across a posi on here. I'm going to crack mine tonight to check the ratio #s on the gear and maybe get lucky. LOL... Any advantage to having a gov posi in a 4wd?? Does it stay locked untill a higher RPM or does it stay unlocked unitll a higher RPM??

Re: OUCH! My rear end hurts
jayharrell,
I never does "lock" that's an optimistic marketing type name. It is a clutch-type unit that has "variable" pressure applied to them. It is supposed to act like an "open" differential until one wheel spins a certain amout faster than the other. Then the pressure is applied to the clutches. The little teeth on the gear (bottom arrow) spin the shaft (upper arrow) which makes all of that happen. I have heard that they are not too bad in the big 14bolt Full-Floater axles, but in the 10 and 12 they just won't last with any performance up-grades. More power and/or bigger tires can kill them pretty quickly. |
