Slip-clunk from rear on hard left launch
Greetings and Merry Christmas.
So I can feel a slip-clunk from the rear when I leave an intersection TO THE LEFT.
My 1969 Chrysler Newport Custom is stock and original with just over 100,000 miles.
I think that 46 year-old gear oil probably looks like coffee jello and should be changed.
That locker needs to be in an oil bath so torque can be transferred smoothly to the inside wheel.
I asked a local lube shop about the problem and right away he claims something is loose and the whole thing should be rebuilt.
Interested in your thoughts.
Regards, Captain Chrysler

The only reason I ask, is that I was getting a clunking sound from the rear on deceleration, and thought it was the sure-grip, the drive shaft, tranny, etc, etc. Finally did a full over haul on the suspension and the sound/clunking disappeared. Apparently, the leaf spring eyes had elongated, the sound that sounded like it was coming from the drive train, was just the springs slipping in their mounts.
Don't know what it is in your case, just sometimes with stuff that old, things ain't what they seem.

Springs and bushings look good.
So now I'm thinking The Ghost needs a 727 tune-up. I can't imagine the little old lady who drove the car for 45 years abused the transmission. I think a new filter, fresh fluid and adjust the bands, and that slipping will go away.
It's only money, Captain Chrysler

I had a long talk with my right foot, and we're going to wait till the problem gets worse.
