Bad day for me. I have a '85 K30 with a th350/np203 I just put in. Trying to sell it to finance another truck. Long story but two trannys later it's been running fine. Was about to put a for sale sign on it and take out an ad locally. About 1/2 mile from the house start hearing sound like u-joint going out. Kinda grinding and pinging. I slow and it gets worse with much louder grinding and some crunching sounds. I stop and crawl under. All u-joints okay along with front axle to stub axle joints. Get back in and it acts like I have the parking brake on. Give it a little more and much more crunching and grinding. CRAP! So I slip in 4low and grind and cruch to the curb so I'm not in the middle of the street. I'm about to go pull my driveshafts and tow it home. This really sucks, was wanting to get this sold. It's a great truck, but tranny and now t-case make me want to burn it down. Anyway, got an ad for a np203 in the 'wanted' forum. Anybody with experience in these?? Is it worth trying to rebuild it or just easier to replace??? thanks.
