ive noticed a lot of u say to park on a hill when filling your differentials. In my owners manual and on the amsoil website it says do not fill differentials above a certain level, either a 1/4" or 3/4" below fill hole. Is it hard on my diff's to overfill them?

Shes a 2002 dodge ram 2500 slt 4x4

 

2002's still used the DANA's and did not convert over to the AAM's untill 03 for the 2/3500's. with the dana axels it is full when the oil starts comeing out the hole, AAM's actualy have a mark on the cover to show where the fill line is, about 1/4 inch below the opening of the fill hole.

it isnt too hard on components when you over fill by a small amount, however if you fill'er to the brim on a decline you will run the risk of frothing the oil. this is a bad thing to do since you are introduceing alot of air into the oil and the oil cannot pretect properly.

 

thnx drew

 

hey drew one more thing. on the thread for cummins quickservice? i was trying to find my engine # and cant find it. there is a sticker on the drivers side of the valve cover but it has only 5 digits. any ideas where the number might be? thanks again

 

it is going to be the engine serial number. this number is on that sticker. it will be a rather long number.

 

it must be rubbed off or something, just two 5 figit numbers is all i see. stickers all cleaned off

 

there is a 7 digit number on the bootom right hand corner but it says it the label part number?

 

hmm. . .I might have to take a pic of mine and point it out
