new to this..want to know how to find front and rear gear ratios

 

Find the code letter on the door jamb sitcker and post it.

 

cannot read it faded really badd

 

Look for a tag under one of the bolts that holds the rearend cover in place. Look on the front one and the back one. Post them up and we can figure it out.

If you can't find any tags, then get a floor jack, put something on either side of the front tires so the truck will not roll, and put the jack under the rear pumpkin and jack up BOTH rear tires off the ground. Put something under the truck so it won't fall on you if the jack fails, and get some white out or a piece of chalk and crawl under the truck and make a mark on the driveshaft. Then make a mark on each tire.

Get a helper, and slowly turn BOTH tires 1 turn while counting the number of turns the driveshaft makes. See if you can make out if it turns 4 turns, 3 turns, 3 1/2 turns, etc. Report back how many turns the shaft makes. If you want more accuracy but more counting, turn BOTH of the rear tires 10 turns, and count how many turns the driveshaft makes. If you turn the rear tires 10 turns, and you get 35 turns on the driveshaft, that will be a 3.50 rearend. If you get 30 turns that will probably be a 3.07 rearend, etc. Doing it the 10 turn way it may be easier with 3 people. Report back what you get.

Sure would be easier if you could read the door jamb sticker.
