NP 231 Problems

I have a 97 Ram 1500 w/ np-231. I started noticing a grinding then a clunk when hitting the gas. I pulled the transfer case and first noticed the snap ring after the bearing in the tail case broken. Can I stop and just replace the snap ring? Will a broken snap ring cause these sounds.
Thanks.
Thanks.

I have the same problem that you described, when I took my t case apart I had the same retainer ring broke, so I bought a new ring, replaced it, and thought all would be good. I thought wrong, when I put it all back together and tried it out, the same thing happed immediately. I thought maybe there could be something else wrong. So before I look at replacing my t case I wouldn't mind trying a that "transfer case saver" you mentioned. Where did you order it from? I tried looking at the Sonex site but couldn't find it. I think I'll change out the chain as well this time. Thanks for any info

I know this thread is a little old now, but I have the exact problem, and in searching around, I think the T-case saver has moved locations (old links I found were dead).

What is required to replace this part, do you have to pull the entire transfer case, or can you just remove the tail shaft? They have some good diagrams for the install on that site, just curious if anyone had actually done it, and what results you had.
Thanks!

Snap ring can be replaced by removing tail piece only. But the noise heard is the edge of the gear grinding in side the transfer case, when ring snaps the shaft can move, usually under acceleration. This will usually make small metal
shavings in the case. At least drain case and refill, or better to pull cover and inspect/clean out. Also check u joints on drive shafts if bad can cause extra load on snap ring, shaft splines should be lubed good too.
