I'm on a roadtrip in Alaska and the Yukon. Looks like I have a failed U-joint just in front of the rear diff. I can't tell if the joint is replaceable or not. Looks like I have to replace at least the rear part of the two piece shaft? Or both parts? Truck is a 1990 extended cab pickup with 22re. Is the V6 shaft different from the 22re? Also, can I pull the rear shaft and run only the front wheel drive? Issues with that? I will be in Juneau on July 14th/15th. Are there any mudders who would know about parts options in Juneau? I will be in and out of cell/internet access from now until July 24th or so. Phone or text is 778 554 5383.
