Both the ‘04 & ‘05 are 4wd.
Howls under load. My understanding is that the front end is the same for all the 3rd gen’s.
They can’t be.
Then you need to swap both front and rear. Otherwise, you will have different drive ratios in the front and rear. If you put the vehicle in 4WD with different ratios things break. Usually not cheap things. Usually it's the t/case as it can't take the difference of one turning faster than the other.
then you need both F&R diff from the donor. you cant have mismatching ratios.
That’s a lot of work.
right but you cant run 373 and 355 in the same truck. if not you can disconnect the driveshaft and essentially get rid of 4x4.
Getting a junk yard 3.73 rear would cut the work in half.
Are these 3.73 all limited slip on the 3rd gen’s?
No, there's also open. Axle code 46 is 3.73 open and for the limited slip the 1st digit will be a letter, D3 or D6 I believe.
If 46 is the open, as 45 is the 3.55, then D4 must be the limited slip. I have a D4, but I didn’t know that would say limited or not, thought it only meant 3.73.
I was able to locate one locally(only one in Atlanta) for $200. Only has 139,000 miles on it.
Worth the money for them to pull it for you.
