Anti spin differential

[markqc]

What should I physically look at to confirm if I have the anti spin rear differential option? (2007 Quad)

Thanks,
Mark

Check your glove box on the options sticker. It should say if you have LSD.
Another way is to hammer the gas pedal if both wheels leave rubber, then you know it has LSD.

Thanks for your reply. Is the options sticker possibly located somewhere other than the glove box? (2007) I noticed in the rain when I press on the gas fairly hard that I can hear the wheel spin longer than I would have thought. My truck is supposed to have the anti spin, I would like to confirm that it does.

Thanks,
Mark

Jack up both rear tires. Spin one wheel by hand. If they both spin the same way it is limited slip, if one is backwards it is not.

Just take it out to some road out in the back woods and hammer on it...2 patches of rubber = LSD one patch of rubber = open diff.

Easiest way is look in the glovebox for the sticker. Second easiest, but, much more fun way is the back road test.
