Hey guys, this might be a stupid question but I was wondering if my 87 lx 5.0 came with a posi rear? Because only one tire spins ( passenger side). If they did come with a posi then is there any possible way its not working because im low on diff fluid? Thanks:bigthumbsup

I know in 89 they came with limited slip and low fluid can definitely cause it not to work. If you're low on fluid top it off immediately since the limited slip is only a small part of your worries.... those bearings and gears need oil too.

i've never seen definitively either way, but it is my understanding that "traction-lok" came in the svo and the 89-93 gt for the fox bodies... i'd imagine the cobra too.

Your 8.8 rear has a trac lok which is a limited slip. Now you are doing a one wheel peel then it most likely needs to be rebuilt and that requires open the diff to remove the carrier for a rebuild and it's not to costly.

do i need a rebuild when- i do a burn out i get the one wheel spin but if i just floor it i get both to spin or leave black marks?

Yes you have limited slip and it will need to be rebuilt. You may as well install gears while ur at it. I know the new clutches are only 100 bucks

alright so it looks like I need to rebuild it. Thanks guys!

so while we've got this going... it came out as early as the svo correct? what year did it start in the 5.0? all models?

Traction-Lok was required/included with the turbo and 5-liter engines starting in '82. Model/trim level (LX, GT, SVO, etc.) makes no difference.

well im not sure about all that, but i can tell you for a fact that the LX 5.0 from at least 1990+ have the limited slip (positive traction) rear end.
