Also feeling a little ''lumpiness'' on coasting to a stop from 50 MPH. I hope that's just the new differential breaking in. Diff shop said to run 15 - 20 mile hops til 500 miles elapse, then flush rear gear oil.
I must be rounding the squareness off new parts.

I've never heard of this before, do the gears howl, clunk or whine on decel ........

Nothing audible. It's more a feeling. I think before I got the handbrake cables put on, the shop guy set my rear brakes a little tight.
After a 10 mile run to the shop downtown, he noted the drums were hot. When the left one came off, some black dust fluttered down. He said after a 10 mile run, the heat was normal. [It's also Summer in Tucson.]
Now after the new rear brake cables are on, it seems to glide better. But, after I change out the fuel sender float, I should do another 20 mile break-in run, and listen for anomalies.

If you're talkin rearend gears, transmission/transfer case gears they should never make noise. Now if you are running a coarse tread set of tires they will make noise. Now, I have heard some pretty noisy camshaft gear drive gears make noise like crazy. Especially if they didnt get the idler gears installed right. lol

One exception would be the Muncie M-22, which sported spur-cut gears instead of the usual helical-cut gears. This was done to enable the transmission to handle greater amounts of torque. Noisy, so it was called the "Rock Crusher".

Tires are highway treads
I took a solid hit in April. Dead center on the right rear wheel. KO'ed my old 12-Bolt 3.73 Eaton posi I had been running since Mid '80s. Made a boomerang of the old Panhard bar. I wasn't sure about the Trailing Arms, so I replaced them for GP. Got new bushings pressed in them and the replacement Panhard bar. A brother Board member helped me out with a lot of stock parts he still had. Only charged me for postage. He lowered his Stepside, so they were surplus to his needs.
So far, I've had the 12-Bolt rear replaced with an open 3.73, new bearings, shims ring gears, axles, etc. The Diff is to be broken in with 15 - 20 mile hops thru to 500 miles. Then I change the gear oil.
I got a new rim on my right rear now. Tire was good. I haven't had the other wheels balanced after the fact. Either the truck wants to pull left, or the steering wheel is cocked 2 points right. I did let go of the wheel for a straight run at about 45 MPH -- it seemed to track straight. But an alignment would not hurt.
Some body panels got jostled. And that's what I might be hearing. Realigned body tin, that hasn't self-adjusted yet. I need to R&R the right rear step fender. I have another '68 fender. Paint is the issue. It's Gold. It needs to become 516 Orange.
One step at a time.

What I did today was R&R the brass float in the in-cab-tank Fuel Sender.
A friend sent me his not-so-old Fuel Sender. He went LS and has an in-tank pump, so the old school part was surplus.
When I pulled the Sender, I immediately found the gripe: the brass floatball was full of gas. That was why it read Empty at a half-tank.
I used a brass drift rod [so as not to spark] and drove off the lockring, pulled out the Sender and decided, the fastest thing would just be to swap float balls.
After the install, the original gripe was fixed. The needle pointed to half-tank again.
However, I was not off that easy. While whacking at the lockring, I must have hit the brass terminal stud and ruined its seal on the sending unit base.
When I did not get a long hiss on unscrewing the gas cap, I suspected trouble.
While it's supposed to be self-venting that gas cap has always been a Non-Venter.
Strong gas fumes in the cab are present.
Having just filled up, it will be another 200 - 250 miles before fuel level is low enough that I can work on the Sender.
I also want to get the Jeep part plastic float. AutoZone was unable to find it. Summit has them for $5.99, but add $13 for S+H and $1.30 for state sales tax and it got expensive.
Anything like RTV that would be fuel-proof and hold up to pressure?

Maybe I missed it, but have you had the frame checked for damage? It sounds like it may bent - ??

Not yet. I intend to get it checked.
