Location: New York | Just started road testing my 58 Plymouth and noticed a clicking sound that varies while only moving forward in drive. Doesnt do it in reverse. So i raised the rear wheels and put it in drive and the clicking stopped, completely silent and nice. So i inspected all around the driveshaft and drums and found nothing obvious. Lowered the car and still the driveshaft is clear all around. Jacked up the front tires and spun them with no sound.
Drove it again and still makes a click once every wheel rotation only while driving and it varies in intensity. With the car not running and pushing it forward in nuetral it makes no click. Applying the brakes makes no change to the click while its happening either. Only when the suspension travels a bit from a road bump did the clicking die down, so Im guessing my leaf springs are sagging a bit, and possibly the u-joints are the culprit. They seem to clang a bit when the car stutters in reverse a bit. Autozone seems to carry them so thats next!
Anyone else ever have this issue?

Location: New York | Just adding that it seems to happen only when there is load on the driveshaft with the car moving forward. I noticed how weak the springs and rear end mounting seems to be. I think the rear shifts position while under driveshaft load and that puts the ujoints in their worn out spot. Never done it before but maybe releafing is on the horizon too. |

| how old are your ujoints? A ujoint can make this noise, it can feel tight but be dry of grease and will only get worse. |

Location: New York | Thanks. Yes it's old and dry looking. Its the ball and trunion at front and the boot is cracking. I hope to remove the driveshaft today or tomorrow to further inspect. Going with this double Spicer u-joint conversion.

Location: New York | Just ordered the new driveshaft. Ten days or so until arrival.
When I was taking off the old driveshaft a little bit of trans fluid leaked out when i loosened the flange bolts. Just a little, like it was accumulating there behind the driveshaft flange. Is that normal or is it time to look into a rear seal replacement? |

Location: northern germany | Big mistake, search this site B&T vs slip yoke. Don't replace it if it isn't bad, if it is (rarely the case), rebuild it. Cheaper and better in ANY way in the long run. The Mopar B&T is nearly indestructible and needs very little service. One of the great features of these wonderful cars. Keep it FL.
IIrc the fsm mentions clicking/ticking sound under E-brake.
