one-wheel burnout

ok this may sound stupid... but my car is burnin out with one wheel, its never done this before... whats wrong?

your posi is worn out. a positraction rear end is just an open rear with conical clutch packs to limit the spin of one tire under acceleration. so when the clutches wear out, you got a one legger. time for a rebuild. or better yet, upgrade to a torsen :)

wow, u answered faster than i hit 'back'... thanks. ironic... i was makin fun of my friends camaro a while back for burnin out w/ 1 wheel.. i hate when that happens.

wait.. does that mean my car is runnin on one wheel, or does it only do that when i burn out?

lol, what can i say, im quiiiick :) and yeah, irony is great, but under acceleration with the tires not breaking loose, both tires are putting down power, but when you accelerate enough for the tires to break traction, the one tire will get all the power, and the other tire just kinda drags.

A little off topic here, but perhaps a little on topic as well.

I thought the differencial should to that job. At least is does that on my regular car.

EDIT:
Forgot to mention that there is no clutch in my rear end, just hard gears. If something slips there.... :banghead: The whole rear end must be rebuilt, or changed.... But they only slip if they run low on oil or the oil is worn out.

lol, your rear end wont slip, it'l break. usually spiders

Hehe.. Yeah I know. I was just trying to make a point with using the word slip :rolleyes:

depends on what rear end you have, open rears are a loose connection of the axles at best, and both axles turning opposite directions at worst. (spinning one tire while rolling backwards down a hill) posi is a step up, torsen is a torque biasing gear driven rear, and a locker solidly links the two axles together. so there really is no one stop answer for it all ;)

i have a home made posi unit laying around, the spiders were welded in, i was gonna put it in my camaro but i went with a torsen i got off ebay,still havent gotten the rear together :banghead: god d*mn shims

just a tip,
Shouldnt use lockers or welded axles on street or daily drivers.. They were meant for straight line racing.. Going around corners, your L and R rear tires turn at different speeds.. A locker will prevent this.. It'l chew up your tires, car will corner like shit, and eventually wreck your rear end as well..

yup, thats exactly y im not using it

is torsen tougher than a posi? does it use a clutch too?

I think a posi is older technology and an LSD is newer

Lsd????

Not Acid... Limited Slip Differential

GM's "Posi" Rear end actually was a limited slip

Lsd????
Limited Slip Differencial.

This is what I have in my daily driver. (75%)

I thought there is a difference between Posi, and LSD?

to my knowledge there is no diff between posi and LSD, they are interchangeable to my knowledge.

as far as torsen, no there are no clutches, its a gear driven, torque biasing differential, that actually takes power away from a slipping wheel and sends it to the wheel with traction, so you never loose power to the ground. and it is much tougher.

I have a welded rear, and it only chews shit up when I go around a hard corner faster than I should anyway. Other than that I havn't had much of a problem.

I thought there is a difference between Posi, and LSD?

There is a difference between a Real posi, and LSD.. But the posi rear end GM used wasnt an actual posi rear end.. It was a limited slip..
A true posi rear is more like a locker, or welded axles.. Theres always power being transfered to both rear tires..

Thanx for clearing that up.. question for everyone, is the Torsen a superior unit to the Auburn?

i would say so, but thats my personal opinion, because the main difference in the torsen to all other rear differential carriers is that its not only eleminates one wheel spin, but can actually send different levels of power to each wheel, say for instance your driving up a hill with power at 50/50 and as you go up you hit a patch of oil lets say with the right rear tire, normally that tire would start spinning, and power would stop going to the other wheel, with posi, or a locker, that tire would be pretty useless but youd still only have 50% power goin to the tire with traction, even if the right tire wasnt spinning. with a torsen rear, it can actually bias the torque, sending say 80% of the power to the left tire with traction, while still giving the right tire the 20% power it can handle without slipping. thats the style diff they use in hummers, ever notice that when a hummer is off roading, and say the right tire is lifted up into the air, it stops turning, that is because 100% of the power is being sent to the tire on the ground. im not sure exactly how it all works, i do know that its all gear driven, and it senses tire spin, and takes power away from the freewheeling tire. you can try the website for more info, i think its...

nope i was wrong.... its actually

note - the fourth gen F bodies used the T-2 style torsen i believe. could be wrong but i think thats right.
