Vibration problem(my milkshake brings all the boys to the yard)
New member, thanks for having me.
On to the questions..... 1999 Ram 1500, 5.9, 4x4. Yes, I read and searched the forum, but peoples descriptions/symptoms seem kinda vague.
I have a vibration that manifests itself quite frequently. Happens at all speeds, engine on or off(rolling down hill) Not constant, it will start small, rise to a crescendo(at which point my cup holder is bouncing up and down, spilling the morning lifeblood) and then fade away for a while, rinse, repeat, rinse, repeat...... 2WD or 4WD, same thing.
I feel it in the body of the truck, feel it through the seats, I see stuff bouncing up and down in the cab, it's not wheel balance, nor is it the dreaded DW (lotsa experience with that, also have a jeep.....)
Granted, the front end needs some work, but it's definitely not the front end. Not the brakes. It almost feels like the driveshaft is out of balance, but I checked the u-joints for play and they seem ok. It;s almost like a couple of things are syncing up and then it starts until the sync goes away. I did find a bad front hub bearing(replaced on the side of the road somewhere in SC during a road trip- did I mention I'm a semi retired mechanic-and always carry tools?) That wasn't it. Literally, I could make a milkshake in the cab when it starts. And I'm kinda tired of all these guys on my lawn.....
I'm at a loss of where else to check, This has gotta be a Ram thing. Anyone? Bueller? Bueller?.....

It does it rolling down a hill, meaning low speed. I would put the four corners on some solid blocks or ramps with block of wood on them then put it in 4x4 and drive then let the wheels roll while I was under it looking at the wheels/axle shafts/drive shafts to see if it'll show me something that ain't right. I would also put my ear to the transfer case while things are spinning.
HeyYou mentioned rear brakes, I had a blown wheel cylinder and it made that tire lock up at low speed on gravel when I breathed on the brake pedal. Brake fluid makes those pads really grabby.

You say it's not your front end but I think that's where you should start. A lot of loose components and stuff can start causing vibrations, shakes etc. Take your driveshaft out and inspect the joints. Replace with Spicer joints if they are bad.
I just went through chasing a vibration on mine and replaced a lot of stuff I knew was wore out...track bar, sway bar bushing and end links, shocks at all four corners, had the tires balanced, wheels aligned and a few other minor things and that took care of the vibration 99% (i think my 10 year old cupped tires are the other 1%).

It's a good idea to adjust the rear brakes at every oil change since the stock adjusters don't do their job very well. You don't even need to take the wheel off to adjust the brakes if you have the knock outs replaced by rubber plugs on the back of the drums, you just need two flat heads and a jack.
Which pads did you put on there? I learned my lesson to not get ceramic or Wagner Thermoquiet pads.
Since you tow a lot then helper springs or airbags would be a good investment. I have add a leafs and they make the ride pretty stiff unloaded but they're great when I load the truck down because it barely squats.
