okay that tells me that your front drive shaft constant velosity joint is worn out

new ones are available on ebay for around $55.00 dollars

On the way to work this morning at 40 miles an hour shift into neutral the front end or the steering wheel itself is just totally shaking cannot figure this out

is the u-joint you replaced or the constant velosity joint

the constant velosity joint is what required replacement , if that is what you replaced

then remove the front drive shaft and try to wiggle the front output shaft on the transfer case

if there is a lot play ( looseness ) then the play in the transfer case output shaft is what is causing the vibration

also check for play on the front drive shaft pinion flange ( what the front drive shaft u-joint bolts to )

Since you have already chased a lot of possibilities without resolving your problem, I am gong to throw something out there that has a very slim chance of being your problem but a possibility non-the-less.

I had a problem in my 89 STX in the rear. I would get a vibration only under hard acceleration. Smooth as could be coasting or decelerating. Everything in the drive-train checked out good as inspected without disassembly. I suspected something in the differential was wrong and took it to a drivetrain specialist for an in-depth inspection. They took the differential out, inspected it and could find nothing wrong with it.

I then took it to a Ford dealer to see if the could figure out the problem. They put it on a dyno and got the vibration but could not figure out the cause. They continued to run it on the dyno for a couple days on and off, trying different things to chase down the problem.

I got a call a couple days later and they told me they found the problem. While on the dyno the rear differential blew up. It seems the carrier had a crack on one side and under hard acceleration is would open up a little causing everything in there to run out of true with an imbalance. The Ford dealer ran it long and hard enough to make the crack grow to failure. This of course destroyed everything in there. They did find the problem and saved me from being stranded somewhere but it ended up being a very expensive repair.

The front differential on the Ranger is not an overly strong unit. You could have a crack in the carrier that is bad enough it opens easily resulting in a dynamic imbalance with a vibration. Again, this is a long shot but a real possibility.

out of balance drive shaft would vibrate on coast and acceleration

my jeep years ago spit a balance weight , i thought my drive shaft was ready to self destruct

That's the only thing that I can think of because the rear companion flange at the differential was replaced because it had arrested u joint in it and the drive shaft was not balanced after that new coupling was put on so I'm kind of at a loss

Cheese_man I just checked rear axle bearings and they seem to have a very serious amount of play on both sides,what do you think about that causin all this vibration ,both up and down and side to side, thanks man

i would have those rear axle bearings and oil seals replaced as soon as possible , before you lose all of your rear axle lubricant , and suffer carrier bearing seizure

serious play in rear axle bearings would in fact cause some driveline vibration

Just putting in my two cents, but I had the same problem and just recently resolved it. I also had the vibration that was much worse when I let off the gas i changed all the rear brakes suspension all around the truck i swapped both axles changed wheel bearings and that brought me to the transmission so i took it to a shop and they told me after test driving it seemed like the torque converter was slipping and that i had a random misfire on the engine but it wasn't throwing any codes. So I got a new coil as i had the original and put in a new torque converter and it seems to have gotten rid of the large vibration i was getting when letting off the gas. So my advice would be take it to a trans shop like AAMCO if you have one around you they test drove my car for free two separate times

Had it up on floor jack and drive shaft had a good amount of let's call it vibration, going to tranny shop on Monday, this guy I know there says he would be very surprised if he can't find the problem, if not it will be for sale,love the truck had five rangers but if you drove this you would scatch your your head,thank you

Cheese_man it's at tranny shop now they think slip joint may be worn ,going to check balance today, he also brought up the front hubs because the vibration can be felt in wheel, so when I get it back I will do new hub assemblys but can't think of anything else when I first lubed slip joint, truck had 129k and it was bone dry so we will see what happens, thanks for all your input

although they are expensive in many ways

do not buy the cheap bearing , purchase the timken or SKF wheel bearings

slip joints in drive shafts can be tricky , in order for the slip joint to work properly , the drive shaft itself must have a small beather hole ( slip joint moving in and out displaces air or creates vacuum )

so a breather hole is a must , if the drive shaft does not have a breather hole , then 1 should be drilled into it .

a transmission man i dealt with several years ago , always drilled breather holes in drive shafts to alleviate drive shaft vibrations even when the shaft is already balanced

Had driveshaft on machine and he was not able to balance the shaft due to excessive play in the slip joint,could not be balanced at all, all over the place,sent another shaft that was in perfect balance to the shop and will go in fist thing in am, what do you think,I'm hoping this is it,was on gas it takes up the slack but when you let off is when it vibrates so I'm hoping that it will be fixed

slip joints in drive shafts should be lubricated every engine oil change

the worn out slip joint could very well be the problem
