The rear drive shaft went bad, worn out. Couldn't find a match, had to use a Pathfinder shaft to work with the trucks old shaft. It's hard to find parts for these trucks.
The truck itself is very reliable and yes the body's are made of tinfoil, but the engine and the running gears are good.
My truck had the Z-24 in it and I pulled it out and put the 3.0 in, what a difference! The 4 banger is so underpowered.
Would like to get in touch with the author regarding replacing my 2.4L with the 3.0L.
I had an 89 that the rear U-joint went out in as well... couldn't fix it because they're staked in. Couldn't find one in a junkyard because they only used those for a couple years and Nissans won't die!!! I'm upset though because after waiting 2 months to have someone fabricate a new drive-shaft for it, I got T-boned at an intersection and totaled the truck! Oh well, now somebody else will be able to get my nice new drive-shaft from the bone yard (I still visit it sometimes...).
I too have had to replace my drive shafts 3 times, I found a place in Gardena Ca, fixed it for $35.00 plus they inserted a zerk fitting into it.
