single piece driveshaft swap

I have 1996 Toyota Tacoma extra cab with 3RZ and a 5 speed. I am just over 100k miles and will soon be needing to replace all the U-joints on the rear driveshaft again AND the center carrier bearing, again. Soooooo. With all that work to do, It might be simpler to just swap out to a single piece driveshaft. There is an article on 4x4 wire about this,

But it wason a truck with 2 inches of lift where as I am stuck with stocksprings. (Yea I know, why havent lifted it yet). So I know that I knowthat I can have a shaft made. I am curious about clearance at thecenter cross member where the Center bearing used to live. Anyone elseout there done this? Any Ideas? Anybody got ideas about measuring whatthe clearance on a one peice shaft would be without removing the oldone and stacking a ton of bricks in the bed? Any Ideas would be appreciated

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 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

3/8" in all dirrections. Is this normal? Is for off road punishment it nothing that unusual, 75- 80mph to work and back, the random slog through a muddy construction site. I have yet to see if this one flys.

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