What coz the vibration when driving from 20 mph all the way to 100 mph .
I've put new wheels and it's balanced.

 

Did the vib come after u did the wheels
Or later and if it has been awhile u might have thrown a weight and causing it

 

new wheels or new tires?

 

It could many many many things, more details on what type vibration, when it started, etc. Also give this chart a read.

No it's there for almost 2yr , but now it's getting stronger.

Tires

The vib started almost 2yrs ago and it was so little but now it's vibrating so bad , it's like mobile phon vibration but stronger . The vibration increased and decreased by speed and It also had a continuous bass like sound

 

Can you jack up the front of the vehicle? If so grab the top of the tire (12 o'clock) and wiggle it. If you can you could have a bad bearing(s).

 

Put blocks on front tires and then put the rear up on jack stands (so the rear tires aren't touching the ground).
Start the vehicle and put it in drive.
Now get out and drop down to your knees and look at the driveshaft from the side.
If you see ANY type of wobble or jump rope effect in your driveshaft, then THAT is your problem. You need to get driveshaft replaced / balanced /straightened.

I just went through this little nightmare myself.

Oh yeah, if your truck is 4WD, make sure you don't have the front axle engaged when you do this!

Just a thought.

It's 4wd and I've replaced the 2 front hub assemblies and replaced the hub locks with mile marker .

 

driveshaft

 

Yep my driveshaft is vibrating, what can I do to fix this or where can i get one with good price and quality online.

 

You need to check the U joints in the shaft first, pull the drive shaft out (12 point 12 mm socket) be sure to block your wheels before you do this and see if both U joints move freely. You cannot check a U joint without removing the drive shaft so you can full articulate the joints in both directions.

Whens the last time it had new U joints at the front and back of the rear drive shaft?

 

^^^^
This...first....

If U joints are good, PM me and I will give you the info for the place that built mine for me. They are awesome, friendly and professional. My new driveshaft from them turned my Ex's driving experience into a whole new world.

call me @602 997 0906 350 with exchange maestro muffler and driveline ron thats me 20 yrs exp

 

actually I never replaced them , it's the same U joints came from ford 13y ago .

But I did check all the driveshaft front to back and it is clean not damaged at all .

 

Then before you do anything else you need to pull that shaft off and check/replace those U joints. You cannot tell if a U joint is bad by looking, you have to take the shaft off the truck. This isn't an expensive fix, so it's worth the time to do this and change the joints before you lighten your wallet on more expensive causes.
