Vibration from 55+
I need the vast knowledge base here to help me please.
In my 2006 Ranger XLT, 4.0L V6, 2WD Manual;
I am getting vibration from what appears to be the passenger front. I have so far replaced the front wheel bearings (both sides), replaced front shocks and checked rear shocks, rotated tires (to see if it changed) and had front tires balanced. I've also had a friend follow me on the freeway and check the wheel to see if is bouncing, wheel appears to be glued to the road. I have done all the front suspension checks I can and find no indications it is the lower ball joints or tie-rod ends.
This vibration is very in consistant, in different lanes it is better/worse. At times I feel it more in the steering wheel, others my seat and at times the gear shift. I don't believe it to be the engine mount(s) cause when it is vibrating I can shift into netural and the vibration does not change, I have also performed the 5K rev (FORD maitn. manual) and the engine is smooth (along with my expierence with bad mounts in my '94).
ANy suggestions are greatly appreciated.

How are you concluding in is the pass front? I know you had the wheels rotated and all that. You said you had the front tires balanced but why only the front? Where I work I have the luxury of a road force balancer. Alot of wheels and tires can balance just fine but still cause a vibration due to high spots or heavy spots in a tire or a bent wheel. This machine is able to measure that and force match the wheel and tire to get the lowest road force possible, meaning a mark is made on the wheel and one on the tire. The tire gets dismounted and the 2 marks aligned and the re-checked. This usually corrects the problem. A few years back these machines were hard to find in shops, you might have to call around to a few places to find one, and have all 4 tires checked. How is the condition of your tires? If they are badly cupped or chopped they would need replacement.

2 Furyus1 - checked passenger rotor (driver to follow today) it's running out 0.005" on both sides of rotor, turns smooth by hand.
2 Phinxter - feel it's the passenger side front by what my truck is telling me, more vibration in my right foot/hip than my left (I admit my truck could be foolig me).
Alsohe rearend off the ground to check the drive shaft (weights, damage, bent), shaft is straight, original weights are still present (no evidence any are missing) and no damage to the shaft. Both U-joints are still solid. I did set up an indicator on the rims to check axel end play, driver side is approx 7/16" and passenger side is approx 3/8". Talked to the local rear axel shop and was assured this was "normal" and to quote "if your rear axel/differential had a problem you would KNOW it".
I'm going to have the front suspension checked by a shop that can do all the checks I cannot do alone. Could this be the control arm bushings? How 'often' do these were out?
Thanks for the guidence n please keep the suggestions coming.

I'm still pushing for a road force balance, I just did one today because the lady felt a vibration, they balanced ok but they had 35-37lbs of road force and the upper limit is 20. I couldn't even fix it by force matching, she needed new tires even though they looked ok and balanced.

You replaced the front wheel bearings so I'm going to assume that you packed them with grease before you put them on. Put the front end back up in the air and check to see if they are loose now that they have become seated. @ Phinxter, interesting info on road force balance, something new to me. And btw those little 'EEKS' were darn good cars. Had one the same year and it had 155,000mi when I sold it.

Yeah I bought it new, and drive it 60 miles a day. It wont win any drag races but does the job and other than a head gasket and the usual wear out items it hasn't given me a problem. The paint is another story.

I hadn't ever heard of a "road force balancer" before. Sounds interesting.
Years ago a local tire chain (Four Day Tire Store) had machines that would grind tires to make them round while under load. I had it done once and the results were very nice. I haven't heard of anyone using these machines lately. Are they still in use?
If the tires aren't the culprit, then my vote goes for worn front suspension components, along with out of spec alignment. It's amazing what a little bit too much of toe-in/out can do, especially if you have large tires.

Reply after fix!?
Hey guys I have had many things replaced and would love to see your answers after vibration cause FOUND. I have taken all suggestions, done them and still have vibration at 55mph. Done, joints, *****, aligned, shocked, repacked bearings. Will balance tires at wallyworld for 8 bucks a tire today, but otherwise, my rotor should be fine as five hundred people have looked at it but I'll keep it in mind, the hubs are automatic but I wonder if anyone here has thought that to be issue, tie rods would have been noticed by tech at ujoint install right?

cause of it in my '94 is a warped rim. searching for a good replacement
vibes above 35 to 45 then 60-75 which is fastest I've run it.
experienced front end/tire man found it right away.
