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

agree with Don , plus I’ll add housing is a big issue , it gets “ divots” in it where the balls rode for 100 k miles , so how do set like .001” fit along ball travel ? impossible. If not perfect tight and centered ( not easy to do press fits etc) it then vibrates at 70 mph or so . Denny’s is way to go all new shaft balanced perfectly

The back joint is a joke too early on , you may have to buy a new larger pinion yoke for current dana U joint .when used on early 83/4 . Denny can help , That piece is $

The front piece adapts 4 bolt E brake drum to Dana joint , used in Winnebago , then Denny outs a slip spline in shaft itself like you see in big trucks

The original thing is a real DOG , vibration bs etc . Gave up 20 years ago .Go all through rebuilding it and it vibrates . It is 1930- 1940 flat six obsolete design . Period

Do the aftermarket kits have a different identifying part number from the original NOS?
That would help to be able to stay away from the non-original parts.

I would stick to NOS on the kits. From what I have seen, the aftermarket kits do not fit. Also the balls are harder than the housing, so it usually wears first.

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
