    Hey Guys,
    I need to pull the rear shaft on my 89 sub to replace the u-joints.I have the 241 t-case.Is it okay to just unbolt from the rear axle and just pull the slipshaft end out of the t-case.What will come out besides atf? and will the seal need to be replaced?T-case and trans were rebuilt last april.I still have a vibration after doing 14sf swap and getting my angles figured out.I know I need new ujoints but I thouhgt I might have a drive shaft shop balance it while it is out of the Truck as well.

    Just pull it and replace the joints. Atf will come out but it should'nt be too much. You will have to to off afterwords.
    I always replace teh seal when i remove the shaft. It is only $6.00

    Thanks,
    so just a knew seal and some atf.Does anyone think a driveshaft balance is necessary.I was thinking it might have someting to do with running the combo u-jointon on the 14blt.

    At the speeds the rear shaft turns, and how often it's in use (compared to the front) I'd consider balancing mandatory.

    Check your motor/trans mounts too, make sure everything else is tight.
