I have an 06 ram 1500 quad cab 4.7 and the front differential is bad. Can i use a differential from an 04? Are they interchangeable?

Well, after looking through Star Parts at the different part numbers it appears that the part numbers are different between the 2004 and 2006.

Ok. I found one from an 04 for $225, i was told they were the same so i got it but when i got home i found they look different. The 06 is an electronic actuator and the 04 is a vacuum. They are almost identical. Now i wonder if i can use it and just figure out how to hook up the vacuum actuator?

I can send you a copy of the 2006 model wiring diagram if you want to wire up your own switch to engage the front axle.

Why don't you swap all of the parts from the 2006 axle to your 2004?

The end that the actuator is bolted to is what is different and that is what is bad on my diff. It's bad where the passenger side half shaft goes in at the diff and i figure a lot of metal shavings have probably gotten into the gears. I dont think that section is removable from the gear housing, I'll have to look.

Provided all the mount points, etc, are the same between the two, and the axle ratio is the same, I'd swap it, change fluid, wire up an axle lock toggle, and call it done. Don't forget to cap off the vac. lines, truck-side
