Frustrating
I had a 2001 2 wheel drive ext cab ranger, it forever had a vibration problem, everything was thrown at it, brakes, drive shaft, rearend, to no avail, now I have a 2011 ranger sport ext cab 4.0 with the same problem! It feels like an out of round tire or tires, I’ve had the tires road forced balanced, at 30 to 35 shakes in my but, then again at 51 to forever! Don’t get it??? Any help would be appreciated
Welcome to the forum
Never had that on any of my Rangers, unless it was a bad tire
You are in Florida the land of NO hills, lol, but if possible when going down hill at 65mph, shift into Neutral and let RPMs of engine drop.
See if vibration drops with engine/trans RPMs
Just to take drive train off the table
So you feel the vibration in the seat not the steering wheel?
4-wheel alignment?
Same road or any road?

I once had a vibration I couldn't find. It turned out to be the transmission tailshaft bushing. (due to the frequency though you should be able to tell if its a tire / wheel or driveline)
Also, could be a loose / worn ball joint. Sometimes they are sporadic allowing the wheel to move.

Thanks, most of the vibration is in the seat of my pants, i tried the coasting out of gear down a bridge, it still vibrated at the same speed, wondering if i dont have a wheel or axle issue, will have to dive in deeper, only 68000 miles?? Trucks in beautiful shape, cant really grasp how two trucks 10 years apart in age could have the same problems
Yes, very coincidental
Not a Ranger issue or there would be way more posts about it.
Get a clear bottle of water, drink it down 1/2 way put it in cup holder and watch for vibration.
Put it on dash when practical, highway driving, lol.
Whats the make and model of tires?
Try lowering air pressure in tires to see if there is a difference, i.e. if 32psi now lower to 28psi
Then try raising, 32 to 36psi
If you have tire pressure monitoring system (TPMS) light may come on.

Also Ive experienced on a chevette and S10: Your motor mounts and trans mount may be completely shot causing funny driveline angles/engine and trans NOT parallel to the frame acting like a bad U joint and/or sending vibrations from engine to the frame and making a shitload of racket.
Test for this is to slowly pull up to a tied down parking block, set parking brake hard and raise the hood. Now you should be able to see the top of the engine thru the windshield. Start the truck, make sure noone is in front or behind your vehicle when doing this, put it in drive or slowly let the clutch out and apply a little gas. See if the engine jumps up or not. Do the same test in reverse, see if it jumps up or not. It should NOT move more than 1". Sometimes just snapping the throttle can make it jump. That rubber gets soft and cracks and starts deteriorating - also if it got contaminated with brake fluid, coolant, gas, even some greases can cause them to break down. If you drive easy for the life of the truck you may never have to worry about motor mounts - if you jackrabbit start or dump the clutch alot then yea your gonna tear them.
the trans mount just crawl under there with a floor jack and a block o wood and LIGHTLY apply some pressure to the bottom of the trans near the mount - it should NOT move virtually at all. Sometimes a visual inspection can reveal a torn mount.
usually U joints show up at 30-40 mph and again at 55-65 if they are bad.
To eliminate any wheel issues do you have any friends/coworkers with compatable wheels you can swap and try? Maybe throw the spare on the back end and see if your vibration changes? i know its a pain in the *** to play musical tires but that way you can eliminate them completely as a problem.
