How do you know if you have an LSD rear end???

Thanks,
Jake

 

Open your hood. On the underside of it right by the grill there will be some info on the options you truck has, including gears and diff options.

 

Or, do a burnout, and count the stripes![sm=gears.gif]

 

lol my truck sucks at burning out, so i bet its not an LSD but i'll check, thanks!

 

i want to know this also. i found the numbers XCRXT05.95B1 and XCRXEO174GDH what do these mean?

 

assuming your LSD is in good working condition...

you can jack the back of the truck up and try to turn one wheel. one tire will turn the opposite direction of the one you're turning if you have an open differential. they will both turn the same way if its an LSD.

 

If you do have an lsd and dont want one, you can always give it to me.

 

or me...

 

alright i did a burn out and i only had one solid black line..... lol but does anyone know what those letters and #'s mean on the inside of your hood?..... like what indianaman said.... I want a posi-differential... i want both wheels to spin when i burn out. What is so great about LSD rearends?

 

posi and LSD are the same thing. posi is GM's name for a limited slip differential. for the ram its a trac-loc or somethin. they're all the same function.

you most likely have an open differential (or a wrecked LSD).

limited slip helps alot in offroading situations where one tire might sit and spin and leave you stuck.
