Randy I agree with John and Dave, slip spline is a better option. If you are set on original set up, I did find a new trunion casting

Hi Randy,

Just ordered a slip-yoke modern custom driveshaft from Denny’s Driveshafts. If you need help ordering, they could easily reference this one (order #159403) . John Grady did the legwork years ago to supply dimensions, and I verified those dimensions prior to ordering. If you need help let us know.

Lol, my lapses in judgements, at least where old cars are concerned, generally consist of dumping too much money into repairing/restoring them!🤦‍♂️😉

The evidence with this car, tho, is that previous owners definitely indulged in plenty of those kinds of shenanigans🤷‍♂️😄

Long ago in the misspent years of my youth, I always kept a spare driveshaft with rebuilt ball and trunion waiting to be swapped in after too many hole shots or wide open throttle upshifts catching second gear rubber. Frequent application of nearly 500 ft-lbs of torque can and will lead to premature failure.
In recent decades I've mellowed a bit and just enjoy the occasional little 'chirp' going into second gear, and I haven't had to swap in a driveshaft this century. YMMV.
If you're still misbehaving like I used to, a more modern slip spline conversion is probably a more permanent solution. ;-) ?

Hi all,

After checking the u-joints on my F, per a recommendation from Gloria, it appears the ball & trunnion u-joint is getting loose.

I did a quick Google search and found a few sources for rebuild kits, but wanted to see if anyone had a recommendation on any particular source over another?

I did check the club tech page and saw Bob's video on replacing the boot, as well as John's instructions on replacing the driveline with a modern slip spline driveshaft. Any insights/advice on doing this repair, or replacing with the updated driveshaft, would be much appreciated👍

Thank you,
Randy
