Re: {Chrysler 300} Ball & trunnion u-joint for F?

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
