Re: U Joint question.
 
Your yoke is now damaged from the last loose one.

I have 'never' seen a successful fix, the yoke needs replacing.

I had the exact thing happen to my CJ7 and tried to keep using it
'loose' like you have hoping the new straps would hold it. I got away
with it for quite a while too, but...

When it let got again, it grenaded the yoke so the driveshaft turned
into a propeller taking out my exhaust, my gas line and my brake line
while punching holes in the floor of the Jeep.

Re: U Joint question.
 
How in heck do you thing grease can handle the stress of a spinning
driveshaft?????

'If' it was a hydraulically sealed system, then the hydraulic pressure
might allow the u-joint to 'float' between the ear caps, but this is not
even close to that.

Have 'any' slop in a u-joint 'will' lead to failure, usually sooner than
later.
