2WD front u-joint
I noticed that my front joint is on its way out last weekend when I was working on the exhaust. I grabbed a pair of u-joints at the local parts store but when I got home I noticed that they only had outside lock rings and I was pretty sure my front joint had inside lock rings on the trans yoke. I searched on JeepForum but there was no clear answer I could find. The cup was marked p161 and with a little help from google and some measuring it looks like the correct part is a 2-3100 or 5-353X. I bought one today and it sure looks right. Going to put it in tomorrow. Just adding this thread to the knowledge base in case someone else (or me in five years) needs the info.
