Default np231 transfer case

I need some help and advice on what I need to do. Here is what I have going on. I have a lifted truck and I had a small transfer case leak from the rear extension housing. It wasn't that bad so I wasn't to worried about it. I went to the store the other day and when I came out there was a puddle of fluid on the ground. when I got under the truck I realized that the extension house bushing came out and pushed the rear seal out. when I got the truck back to the house I pressed the bushing back in and re-installed the rear seal. The next day it was still leakingbut this time it wasfrom the extension housing. When I took the extension housing off I realized that 2 of the 4 bolt ears were broken off and that is where it was leaking from. I need help finding where to get the stock parts or what upgrades to do. I was looking into the slip yoke eliminator kit for it but I don't know how well they work or if they are worth the trouble.

The best thing to do at this point is to install "slip yoke eliminator kit".
You will however need a new drive shaft but the expanding part of your driveshaft is moved from the transfer case to the driveshaft itself and you'll never encounter the problem you are having now.
Most of the kits you'll see are for the Wranglers. This is done to lenghten rear drive shaft on short wheel based vehicles to accomodate for the lift and elimination of driveline vaibration.
In your case (if you install the kit) driveshaft will never move out of the T-case causing issues.
Same Wrangler kit will fit your Ram.
