I'm leaning toward the 3.92 I still do about 60% highway driving. but the city driving I do is very hilly. I'm still looking for the answers to my questions in my original post if anyone can help. I'm still searching the forums but no luck yet.

 

To answer your questions:
1. Parts you need would be new ring and pinion, master install kit, and a new carrier like a DTT or auburn if you don't already have a limited slip rear. You don't need limited slip, but I think it's a good idea. You can reuse the dodge open carrier if you don't want an LSD and that will cut about $400-500 from the cost.
2. Cost is $1100 and up including labor for the install. The most important thing is finding an experienced shop that does ring and pinion work regularly b/c it's not something anyone can do.
3. The best place to buy parts to avoid conflicts if there is a problem is through the shop doing the work.
4. No, it's a tough job and judging from the above questions it's not something you want to try on your own.

 

Chrysler needs to stop putting the 3.23 gears in theses trucks knowing darn well the fav and best opt is 3.55 or 3.92 LSD's...shame on them! They use it as an upgrade opt for more $ and it's down right dishonest. As far as yours or any junk yard gears...there's a tag on the inspection plate at the bottom right that tells you the gear size...check it on yours for the experience of it. There are also identification codes on the bottom left and right of the housing and some on the axles. The correct way to do this is once you pick the co to get your gears from...ask them for shop recommendation in your area for guaranteed warranty purposes, one that they will work with if a problem occurs from install. I saw that Moes Performance has them but their price was high IMO. I also found numerous shops that had the posi units, limited slip, and lockers at good prices but all you need is the posi or limited slip carrier...not the locker but it is said to be the best. However...I wouldn't recommend lockers in a truck with traction control...the system would probably go koo koo trying to stop the spinning wheel (imo), he he! I saw posi units for 9.25 (that's what you should have) starting around 300+ and gears from 300 to 500 by Goolge Search "Dana 70". You can also google "Dana 60 because all of these sites sell both. Names like Eaton, Richmond and Detroit Lockers are the feild to stay in. Get your tags and codes off of your rear end, have them ready to be safe when you place your order. Most important...deal with one who can recommend a shop in your area for warranty purposes! And last....a junk yard use to be the way to go, but not any more...they rape you. A complete rear end for my 95 chevy was 1000+ every where I went...so can you imagine what this one would cost? Not to mention the unexperienced install of a new type of suspension and what excuse they will use to over charge you. If you need some exrta help finding the right stuff you can PM me and I will help you. I'd like to for once... see someone come out on the happy end of the stick for a change in here with these rear end swaps! Good luck! EDIT: You can get a whole set for 800 at Moes...gear set and carrier with your choice of gears. The carrier is a Detroit True Track that uses a worm drive instead of clutches (stronger than stock) and it's limited slip. Or you could get the Auburn limited slip which looks to have spring loaded clutches and cheaper than the Detroits at 435$. After second thoughts maybe it would probably be better to go with Moes. And they also have Detroit lockers probably the best imo and they do allow wheel speed differentiation while turning. I wish they had 4.30' gears for mine cause that's my choice for when I go up in tire size. Have fun, lol!

 

Or you can get one brand new for a little more, if you want to go this route- http://www.trademotion.com/partlocat...layCatalogid=0

Thats the full assembly, with limited slip, they also have just the gears if you want to do it that way.
