hey i was just wondering if there is a sticker somewhere to tell you what gears your truck came with, i checked inside the drivers door and under the hood and i didnt see anything, im guessing theyre 3.55 if the PO didnt change them, i was wondering more if there is a way to tell if theyre LSD, or open ended

 

you can request a build sheet....and there should be a sticker on the undeside of the hood near the latch

 

yea i just went out and looked and i didnt see anything about gears

 

The sticker may be in the glove box or check the carrier itself.

 

my sticker faded away under my hood (may be what happened in your case)....thats how i couldnt tell, but then i caled PO, and he showed me recipts of 4.10s in the front and rear

 

my 01 has a faded sticker in the glove box that says 3.55 it has a mopar part number sticker on the rear axle tube, drivers side that says 3.55 OPEN

 

you can tell by your rpms at certian speeds with certain tires too...

 

Very easy way to tell if you have an open or LSD.

Jack the rear end of the truck up so that both tires are off the ground. Roll one tire back and forth (it'll spin just a little without much resistance). If the other tire spins in the opposite direction, you have an open. If not, you have a LSD.

Thats how I figured out mine was an open before I even acquired my build sheet.

 

While you have it jacked up for the above test, make a mark on the drive shaft. Turn the tires one full rotation, and count how many times your mark on the driveshaft goes around. That will tell your gear ratio.

 

Besides the under hood sticker on mine,my original rear(long gone) had a metal tag on one of the cover bolts that simply read, 35 on it. Meaning it had open 3.55 gearing. I was told if it was a LSD it would have read,35L.
