Hi all,
I have been going through the archives trying to find an answer to a problem I am having, but so far nothing has helped. Our LC is an '03 with 205k miles and it is primarily my wife's daily driver. The fluids have all been regularly maintained with synthetics.
Symptoms:
The noise started this summer and progressively got worse. The noise starts at very slow speeds and does vary with speed. It is best described as a "wub-wub-wub" sound. It does not change with steering input that I can tell, and at first I thought it was coming from the front, but now I am not so certain.
Diagnosis to-date:
After a month long business trip my wife picked me up at the airport. That was when I first noticed the noise. It seemed to be coming from the front of the vehicle. The next day I went around each corner to see if anything was noticeable and rotated the tires.
Not long after, a vibration developed in the steering wheel. I rotated tires again to try and eliminate out of round tires, but that didn't help. At this time I noticed some lateral play in the front passenger side wheel bearing. As I had to leave again for a trip, we took it to a shop I trust to have the wheel bearing replaced. I picked it up from the shop, talked to the tech and all seemed well with the spindle, etc. However, when I drove it home the noise and vibration persisted. I checked the bearing for preload and it is in tolerance.
Next up I looked into the front CVs. There was play in the passenger side axle CV's. As this isn't too costly I replaced the front axle. Noise still there, vibration mostly gone.
Looking at some of the other posts where folks have had similar issues I went ahead and put fresh grease in the u-joints and slip yokes. No change in the noise.
As I've started to eliminate more of the front end, what should I look at in the rear end that could cause this?
I really appreciate any leads or guidance here...
