About 200 miles ago I started hearing a squeak when I turned hard. Squeak has gotten louder, but I have not noticed any difference in drive-ability, just in sound.
It appears to be passenger side only. When I jacked up the front axle and rotate the tire by hand, I can still hear the squeak. Also, passenger side wheel is getting much dirtier than my other wheels, so this issue is causing something to wear.
Truck has 129k miles on it, 4x4 2500 with Hemi.

Here is video of the problem. I have the vehicle jacked up and i am going to do more investigation today.

Thanks for reading/helping!

 

That sounds a LOT like a dry U-joint. (the two-tone squeak kinda gives it away.) If you turn the wheels, is it better/worse?

 

HeyYou, not 100% sure what you mean by "turn the wheels" so I will give some examples.

Right now the front axle is off the ground and the tires are removed.
Starting with the wheels (now jut rotors) pointing straight ahead, I can rotate them no problem, no sound (good)
As I turn the wheel from inside the cab (as in making a turn) I DO hear the squeak.
As I turn the wheel the other direction (going from far right to far left) it will squeak, then be quiet as the rotors are straightened out, then squeak again as I go far left.
Leaving the rotor turned left, If I grab it and rotate it forward or backwards, I DO get a squeak.
As I continue to rotate the rotor, the squeak continues. Throughout one complete rotation of the rotor there is a squeak - a quiet period - a squeak - and another quiet period. So I hear two squeaks per rotation of rotor.

I am thinking U-joint or Wheel bearing - as those are really the only things moving that are specific to the passenger side of the front axle (please correct me if I am wrong)
Any idea how I can determine which part is bad?

 

Ah, wheels/tires on, rolling slowly either direction, turn the steering wheel a bit. My bet is, the squeak gets worse.

Given your description though, yeah, that's a dry u-joint. If they aren't greaseable, time for replacement.

 

Yes, with wheels on, as you turn the squeak gets worse.

My U-joints are stock - not greasable.
I am planning on buying this part tomorrow - Spicer 5006813 U-Joint

Would there be any other parts needed along with that?
I've got PB blaster sitting on the nuts right now in hopes of making it easier tomorrow.

Here is video of me testing it with no tire on:

Any input is appreciated.

 

Well, you have to basically disassemble the whole thing to get the axle out. So, brakes, if they are getting thin, maybe hub/bearings, if they are getting old, ball joints? You are going to be RIGHT THERE for all of it. Check it all out, and have the parts ready to rock when you actually do the job.

 

6 hours in. have the hub removed. Gonna need to get a u joint press tomorrow. cannot get those suckers out.

 

 

 

Noise is wrong for a ball joint.
