those are a really common(especially with newer cars) inner joint.I am not sure if they are superior to a CV or not, but they dont seem to like high angles like a CV joint does...my neon uses that style joint, and they are for sure easier to service(but when they fail they really fail!) although there is little warning before they go boom(no clicking for a while to tell you something is wrong like a CV will)glad to see you figured it out, and hopefully you will be back on the road for a long time before you break down again.-Owen
Man this thing is nothing but problems eh Arb? It sucks because it happens, but its good because it happens to someone it is not going to be a crippling blow to lol. you know? Hope you get it all solved out and running tip-top-shape
Couldn't have happened to a better person! Every time I see an old Caravan, I kinda laugh to myself and wonder if it has axle problems. Then I think of how cool a diesel caravan is You redefine MINI-VAN and make it cool. lol
...BTW your Bieber avatar is awesome.-Malone
Reading at the head port, 10 psi per 1,000 rpms is great oil pressure. It sounds like you're doing even better than that. No need to rebuild based on those pressure.
