    I have one of highangle drivelines 1 ton shafts in my rig (Nice unit, thanks Jesse), and with it came a new yoke for the NP205 output which houses the u-joints with "u-bolts" that go through the yoke and have nuts on the end. My question(s) is/are, on the other end (connected to the 14 FF) the u-joint is held on with those straps (not as strong in my opinion). I was wondering if anybody has done or heard of somebody enlarging the existing holes and using a "u-bolt" set-up. I know they make a 1410 yoke for the 14FF with u-bolts but the only way they make the 1350 yoke for the 14FF is with those straps (or does somebody make them and I don't know it).

    Oddly enough my U-joint's have more issues than my 'straps'. I know it doesn't look as strong but I haven't had any problems at all with them.

    You could always have some caps made up at a machine shop out of some 4340 and get em hardened...kinda like main bearing caps.[​IMG] J/K! I think the straps are fine IMHO.

    I haven't had any problems YET *keeping fingers crossed*, but I don't want to either. It's like the 10 bolt axle, it may be strong enough but if you are going to abuse it, you may be better getting a D60. I was just wondering what options (besides a hybrid joint and 1410 yoke) I had to make the straps stronger.

    not likely to cause you grief. my 1410 dana 70 yoke uses them. cheap to replace and the spicer replacement includes new bolts with thread lock already on them. the bolts arent as cool as the factory stuff that have that impossible to crossthread tip

    Believe me, those straps are the least of your worries. The load isn't on the straps, it's on the yoke--the straps just ensure that the u-joint doesn't come out of the yoke. Most of the load is on the yoke anyway.
