How can I find out what running gear I have under my truck? I came up with trans and transfer case but am having trouble with the axles. Door sticker just says "H9" for axle and VIN decoder doesn't give up this info. Not sure if rear is standard or controlled slip either?

 

So I overlooked the 44 stamp in the front axle Still notta on the rear though.

 

If its 4X4 the rear and front gears must be the same. So use the numbers off the front tag to see what you have.

 

H9 is a 3.55 limited slip

 

Thanks, I really needed to know if I should add some additive for the slip when I change it.

On the gearing aspect, I understand that front/rear are the same. I just need to know what AXLE I have. 44 is the front but I can't find any info on the rear axle. What is usually in the rear when there's a 44 in the front?

 

USUALLY an dana 88. Thats what most of our trucks have. I believe you can tell by how many bolts there are.

 

Are you kidding me? wtf...........

 

What is so funny?

 

These are the available axles on the model truck I have.
BTW, there is no dana 88. And if you have an 80, you have a monster truck!
