    is there a diiference between gov locks and limited slips? sorry, probably a no-brainer for most of you. I dont know so i figured i'd ask. One way to learn ometimes....just ask the right people! Thanks.

    same thing, though gov-locks lock a little better then some LSD's but are also notorious for grenading.

    It's not a dumb question or a waste of space... I didn't know the answer and the only way to learn is to ask. Anything that informs you or others is a good thing and not a waste....

    How can I miss you if you won't go away? [​IMG]

    There is a pretty big difference. Basically, limited slip diffs in most companies eyes (aftermarket especially) are clutch plates assemblies with springs that keep the axles locked together, except in turns and extreme traction differences between the two tires. The gov-lock uses centrifugal force to lock the axles together WITH clutch plates. So its an open diff (good street manners) when not locked, but when there are traction differences between tires, it locks up. A decent limited slip has just as good road manners as a Gov-Lock, which is supposed to be "transparent" during normal driving

    Thanks Scooby, ChevyCaGal, dyeager. Now i understand more about what i was looking at last night when i pulled my diff cover off last night. Code off the glove box says LS, but now with the info i have, i know it's actually a gov lock. guess GM doesn't distinguish the difference in thier codes. I can understand why the gov locks explode so much just by looking how it's setup. cool design but pretty wimpy. kinda like the whole axle i guess. anyway, found out my spiders are pretty wooped and giving me too much play. banging around in there which my ujoints aren't liking very much. axle shafts are worn also where the c-clip rests so...time to go 12b or 14b i guess. another 10b to the junks. o'well. thanks again.
