Okay. My question is do I replace my hub assembly? I have ruled out the tires, brakes, and alignment.all are new and balanced. I hear a slight humming when I am rolling slowly. A few people have said it is my barrings that are going, but I have to replace the whole Hub Assembly. Has anyone had this problem with the LS 430? This is my first luxury car. It is a 2002. I am beginning to think I should stick with Ford Expeditions.

 

Heh, Ford Expedition? for reliability? They have way worse wheel bearing problems, as well as ball joint issues, rear lower control arms that rust completely through, etc....

Most newer vehicles don't have separable wheel bearings... They are much easier to replace as a unit and tend to have fewer problems over the long run...

Your car is 12 years old now, I think it is realistic to expect some issues from time to time...

 

Yes your are correct.

 

I have replaced the HUB Assembly and I can still feel the vibration a little. My mechanic seems to think it's the cheap rotors i bought.

 

When do you get the vibration? What speed, road surface, etc? Does it happen more or less when the car is cold?

 

It vibrates before I reach 50 - 60 miles. It happens I can say when the car is normal. I just can't figure this out. I am suppose to change the rotors to the factory ones.
