single piece driveshaft swap

You may want to look into why it's failing. U-joints failing at 100k is not normal. I have 290k on my '93 and all the u-joints/bearing have never been touched (next to the lube). When I inspected it last week, everything was tight.

I have an 85 toyota and went to a toyota only wrecking yard and they told me the 87 88 4x4 single piece will work for me don't know if it will work for yours or not but can ask in a day or two when i go to pick mine up.

I have the same truck with no mods. Have you been greasing all 5 main prop shaft fittings every 15k miles per the manual? Absence of that alone could cause them to fail. I lube the front-drive (4WD) zerks less often. What sort of punishment are you giving the truck off-road, etc.?

Yea I have been greasing all the zirks generaly every other oil change. I bought the truck used, and judging by the reciver hitch and the 7 pin trailer wiring jack, it probably spent a bunch of time in front of a trailer, and not a small one either. You know the little things that you over look when you are going ooooh, its got a sunroof. The center carrier bearing is pretty free to move. I can push it easly

if the bearing does not make noise and the shaft does not vibrate and the u joints are good it is ok
