Replacing 1997 extended cab S-10 split shaft to solid shaft

    Ok, need some help. I know some have replaced the S-10 split shaft with a solid driveshaft. I have a driveshaft company that will make me a one piece drive shaft, new U-joints, and use my existing ends for $250. I have replaced the carrier bearing, and the vibration has lessened, but still a little there around 60mph. I want to know and hear from some that have done this, how well did it work out for you? Problems, suggestions, best parts? I know there is a reason that GM made this truck with a split shaft, but I cannot find one problem with the one I have. I know, I know, may be your U-joints, but at $25 each and my truck uses 5, if that doesn't fix it, what next? Is there something else I may want to look at? I own a 1997 S-10 extended cab 2 wheel drive with a 4.3, auto. Thanks for any help.....:great:

    Also, I pull a 8x6 enclosed trailer all the time and the truck has 153k. Even without the trailer, it's still there.

    The U-joints wiggle fine, not too loose. The carrier bearing rubber was worn out, and there is no clunking or play from the rear-end when put into gear or wear on the pinion. I change all the fluids with Mobil 1, rear-end every 60k, trans ever 45k and oil every 6k. The play does not feel from the rear-end as much as middle of the truck. I check the gears closely every time I open the pumpkin, and haven't seen any wear or cupped teeth. The pinion from the rear-end is tight. If it is the U-joints, I would still like to change it to a solid metal shaft, but would like to know from someone who has done this, what were the long term effects? MPG, ride, towing capacity, ect ect.

    Have you had the balance of the shaft checked? Even a small ding on the D/S can cause a vibration.
    Removing the carrier bearing and going to a 1 piece shaft isnt a big issue, like you point out you get rid of a couple sets of U-joints this way, make note of the D/S angle you may need to shim the r/r axle to get the right angle back, this can cause vibration too.

    Thanks, that gives me something to take care to notice. We have a drive-shaft shop here, Huntsville Drive Shaft, that does nothing but build and balance shafts. I am also just considering taking them this shaft, have it balanced, and put it back. The biggest draw to a one piece is the fewer u-joints and a brand new shaft, which I think would be stronger. I really want to know why Chevrolet when to a two piece shaft, then back to a one piece in the last year of the S-10, 2004. I am a little timid to spent the $250 without research then hate it or go backwards. Every little bit helps.

    I don't think they would go to 2 piece shaft if there wasn't a very good reason, it costs a lot more
