Hey guys well i've got a 02 trailblazer that used to be a posi. you see i take it off road and do donuts and spray mud everywhere and when it's wet out (cause it's a chevy and doesn't have enough power to do it when it's dry) i'll whip donuts in the street with it (when there's no cars on the road i've done a donut on route 1 at like 12 at night it was fun it was one of those hold my beer and watch this thingies) but anyway when i go down my driveway (long and twisty) and i don't have my foot on the gas at all or the brake you can hear a noise coming from the rear (right?) like click click click click kinda like the splines on the axel are slipping the splines in the center section. and i was doing a brake stand the other day in the rain and i looked in my right mirror and smoke was pouring off my right tire and nothing comming off the left tire, so i stopped. i was wondering can i hurt the rear anymore than i already have by doing burnouts and donuts and crap? and what do you think is wrong with it? i think the posi is burnt out on it but i'm not sure i havn't pulled the cover cause it's a daily driver and i don't know what kinda rear it is so i don't have a gasket it runs fine when i'm not doing something stupid. can i just put in a fully locked unit?
