Make sure things are not overly torqued. Years back, I experienced tight steering that didn't want to return to center after working on the front end of my Dakota. Had replaced ball joints, etc and didn't use a torque wrench. Ended up tightened things a bit too much. Lesson learned when I had to pull it back apart and torque properly.

 

Update....Steering is perfect now. List of replaced parts has grown. Steering rack, front right hub/bearing assembly, both cv axles, sway bar links and bushings, brake pads, tire balancing and rotation. Also checked u joints on the driveshaft and everything is spinning freely and nothing is hung up.

Remaining problem is the vibration which can be felt in the steering wheel and gas pedal when driving between 70 and 80mph. Between 60 and 70 it’s very minimal and also starts to diminish above 80. This is still accompanied by a whining noise which still worsens when the wheel is slightly moved to the left. It slightly improves when the wheel is moved to the right. As I said above, the right side bearing was just replaced.

Any further thoughts on what could be next? Alamo have a whole new front wind on it but I’m stuck and out of guesses. Could it be from the rear itself or a rear wind bearing vibrating through?

 

Tire balance, or an out of round tire, can cause the vibration.
What ever repair you do to one side you should do to the other.
You could have a warped brake disk, though you usually feel that in the brake pedal.

As I stated, your 2008 should be like mine where the gas pedal is not connected to the engine at all, so the vibration you are feeling is actually through the body.

 

Had the tires rotated and balanced and it did not eliminate or change the symptoms. Would you suggest doing the DS hub assembly too? I only did the PS because it worsened when the wheel turns to the left which would usually mean the opposite side bearing is the culprit. What other items would vibrate through the gas pedal and to the steering wheel in your opinion? Tried to attach a short video so you could hear the noise but it wouldn’t allow me.

 

Bent rims can do it.

 

Yeah, replace the other hub/bearing as well. They both live in the same environment.... so, if one is bad, the other likely isn't too far behind.

Might also want to have the driveshaft balance checked. Though given your symptoms, I don't think that's it.

It IS a balance problem somewhere though....... Check wheel runout?

 

Is wheel runout related to alignment?

I got the attachment small enough to hear the whine also if it helps at all. Again, constant when driving straight between 70-80, worse to the left and better to the right.
I’ll also get the DS bearing done.

see video attachment for sound.

 

Runout is how much the wheel 'wiggles' as it turns. Put a stationary object (crayon...) a tiny distance away from the edge of the rim, then spin the rim. The gap should remain the same as the wheel turns. If it doesn't, that means the rim is bent.

 

I’ll give it a try. Also just noticed the oil pressure gauge reading somewhat high? Does this appear normal for their vehicle? Could the noise and vibration be related? Photo attached.

 

Pressure is still in the acceptable range. That isn't your problem. (that would have been too easy. )
