1999 Pontiac firebird v6 rear diff
Hey guys I have a quick question...I have a 1999
Pontiac firebird v6 (base model) and it’s about my
rear diff. I had it in the shop on the lift and spun one
wheel foward or backwards (does that matter in this
case?) and the other wheel spun in the opposite
direction. Now my teacher said it’s either an open
diff or a messed lsd. Here’s the confusing part....my
door label gave some detail and looked up the
numbers&letters on the label and printed out a list
of what the car came with, and it said my gear ratio
(I forgot what that was) and it also said I have a
torsen rear. My question is that everyone in the
articles/forums were talking about lsd diffs and
open as well. I can do a burnout with the car rear
end swinging out as I’m going foward (it’s fun)
and when I take off from a sharp turn the car goes
and then slightly shakes and both rear wheels
scrape the ground. I tried to smell the diff oil, and I
don’t know what the friction modifier is supposed to
smell like, but it just smelt like oil. So my question
is, is it a torsen diff, open diff or lsd diff or posi
diff??? My door label comes up with torsen, and all
data doesn’t have any info on that except open diff.
This all has me confused up the a** and I need
answers. I’m still going to pull the cover off to put a
new cover on, new seal and a pinion seal. Thank
you!
