Thanks guys. For some reason notifications go into my spam and don't show up on my phone. Jage, thank you again for the e-mail. Yes, stock Ford works. Its a bear to change one out in the parking lot of an Auto Zone with crappy Auto Zone tools. Took several hours, all total, but got it switched out with a cheap-e one from Auto Zone. Got me home and its like a whole different rig. Smooth vs. the feeling of continually driving on rumble strips. Got home at 3:00am. 2200+ plus miles in two days -solo. I'm on a different planet right now. Think I'll stay out of the SMB for a couple of days. Gonna order up all new u-joints and replace them all with good Spicer ones. Would have likely lost my fuel tank and a bank of batts, in addition to the drive shaft) had the u-joint let loose. Like I said, they are a pain to replace on the road, but they are fairly cheap. Words of wisdom today: Change out your u-joints now and avoid the hassle. Interestingly, the E-350 u-joint is only about half the mass of the F-350 ones. Given the greater articulation over stock, weight and towing cap of our rigs, a mod might be in order. If I'm gonna have a weak link, don't want it to be one that will dynamite the undercarriage when it goes. Can't imagine it would be too hard to switch out the yoke from the transfer case to a F-350 compatible one. The rear end yoke will be easy (just four bolts). Drive shaft shouldn't be too hard to come by, I would think.
It takes a village to raise an idiot.
