confused about the rear end

[fadetoblack188]

so my build sheet says nothing about lsd. The part number on rear comes up non lsd..

but if i do a burn out, i leave two lines.

Did you buy it new? I always assumed my 01 ORE still had factory 4.10's in it from info on build sheet but discovered 4.56's when I tore it open to rebuild it so previous owner could have replaced stock w/ LSD. Only way to tell without pulling cover is jack up rear (both sides) and turn one wheel by hand and see what other wheel does...

If both wheels are on the same type of surface, and you can easily break traction, there's no reason why it shouldn't even if you have an open diff.

The most reliable way to check is to pop the diff cover.

Can't use that trick on newer trucks that have a helical gear lsd, as it will behave like an open diff with both wheels off the ground.

I did not know that, good call and thanks for the correction. Fadetoblack, very sorry to waste your time

So if you have one wheel in the air, and need power on the other side... apply your brakes LOL. Anyone know what the bias ratio is on these?

It think cracking the cover is the only option lol.

not 100% true.....if both tires are on the same type of surface AND have equal traction AND equal torque to each side....then yes, you can leave 2 marks with an open diff, but that is rare to be able to do

chances are, you have an lsd that has been added.

And agree on the 2nd part......pop it open to be sure.
