okay, im pretty much a noob so any help would be awesome. Couple of questions, how can i tell what my truck has in it for axles. Its an 88 W100. I think they may be dana 44's but not sure. And can i get anyhelp tuning my 318.

 

If the truck is stock take your VIN to your local Dodge dealer and ask for a build sheet. There may be a tag attached to the bolts on the pumpkin. Otherwise answer these questions.

1. Does it have a cover or is the pumpkin removable from the driveshaft side?
2. How many bolts are in the cover?
3. What shape is the cover? (round, oval, or triangular)
4. How is the front axle engaged? (vacuum, manual hubs, or automatic hubs)
5. What is the outside diameter of the of the axle tubes?

Block the wheels, raise one of the rear tires, truck in neutral, and parking brake off. Use chalk to mark the bottom of the tire and the yoke on the pinion. Rotate the tire one revolution while counting the number of turns of the yoke. (4 1/2 turns = 4.56, 3 1/4 turns =3.23 gears and so on)

Raise the other tire and place the truck in gear. Turn one tire forward and watch the opposite tire. If it turns forward you have some form of posi-traction, and if it rotates backward it is not posi.

 

okay to answer question one, there are covers(pictures of down below) and for number 4 they are manual hubs. I would raise the truck, but I dont have any jacks that go high enough haha.

the tag on this says it has 3.23s in it

I cant make out what the tag says on this one.

 

So we know it is a 3.23 gear ratio. The 12 symmetrical bolts on the cover lead me to believe it is a Chrysler 9 1/4" rear differential. The front cover looks like a 10 bolt and the shape of the cover looks like a Dana 44 on the front.

 

Thanks, I appreciate the help.

 

okay another question anyone know where I can ID my tranny by the numbers on the side pk4431561 9643 1158

 

It is a 727 that was made Dec. 21, 1987 .

 

These had lock-up torque converter right (mines a 3 speed)? And thanks again man, you sure know alot about these things.

 

Lock-up converters started in 78 as an option but I don't know if you have one or not.

 

any way to tell without ripping **** apart
