    Ok...I jacked up my rearend and gave it the spinning tire test. When I spun the driverside tire counter clockwise, the passenger tire immeadetely spun clockwise. Now I'm supposed to have a gov-loc in my rearend, so does this mean I don't? I thought if you had a gov-loc, when you spin one tire it spins 3 times before the other tire kicked in.

    The gov-locked 14 bolt I had, when you spun one wheel [axle jacked up tires off ground] the other wheel rotated the same direction..now the axle is in a friend K5 and I watched him from behind last weekend and under low rpm/low torque one wheel would spin, when a lot of power was supplied both wheels spun..thats 4:11 gears witha 205/400 and 325 hp, running 38' SSR's

    Sounds like you either have an open diffy.....or your Gov-Loc is shot....tires should spin in the same direction when jacked up like that.....doncha hate it when stuff don't act the way ya think it should?......JD

    WellI belive the differenitial in itself is going bad. I've been getting a thumping/churning noise and it appears to be coming from my rear differential. I guess this gives me a good reason to find a cheap 14bolt.

    I had a gov-loc dismantle itself once while I was out camping.....drove from Hot Springs Ark, to Dallas...pullin' a boat.....rearend sounded like marbles in a blender.....it broke for good as I turned into my driveway.....I have 265K miles on that truck, and I will never sell it.....I drove it from Austin to Dallas once and spun a main bearing less than a block from the house......it's sorta like my old, fat girlfriend.....she's ugly, and I'm ashamed of her, but she's just too good to get rid of.......JD

    On my `90 K5 i have exactly the same, when a jacked up the rear end and spin the tire the other side spins in oppeside direction. This does not mean that your GOV-lock is broken. This is the way the GOV-locks work. It`s acts like an open diff until it locks. Try it at a slippery underground make the wheels spin after 1 rotation the GOV-lock will lock and both wheels are going to spin. Above a sudden speed a think 25 or 30 mph the GOV-lock will not lock.

    The GOV-lock is a limited slip locker, and you can`t check if it works by jacking the rearand and spin the tires.

    As already mentioned, if you do have a Gov-Lock, one tire will spin one way and the other will spin the opposite direction just like an open diff. The only sure way to see if you have a Gov-Lock is to pull the cover and take a look.

    Well we pulled the cover off to see what was wrong with the diff. ( a whole nother story). But it is an open diff. No gov-loc. The guy I bought it from said he had the ring and pinion replaced. I guess he had everything replaced and just left out the gov-loc.
