Hello - new to the list. I've been on v8sho.com for a few years now - I had an AX4N blow up on me a few years back and they helped me out.
Anyway - now I'm hearing (and feeling) a low, repetitive rubbing noise/vibration that varies with vehicle speed from somewhere in the suspension that feels like it might be coming from the front end. I have ruled out tires (replaced each one with the spare and drove it after each one was replaced) and warped rotors (replaced each front and rear with a new one and drove it after each one was replaced), and I am still getting this noise/vibration. Searching other posts makes me wonder if I have a halfshaft going bad.
The noise starts at about 20 mph, and continues noticeably up to 70, with it being almost unbearable from 40-50 mph. Braking has no effect on making the sound louder or quieter or changing the vibration. It does however seem to get quieter when I turn slightly to the left, and get louder when turning to the right. Its all aligned, and doesn't pull any direction, braking or not. I just replaced the inner tie rod ends earlier this summer, and this noise has only started in the past month or so.
The only other thing Ive noticed (and this may be normal), is that there seems like a lot of play in the halfshafts. When in park, if I lift one front wheel off the ground (and the other side is on the ground), I can spin the free wheel about 10 to 15 degrees. Is there supposed to be that much slack in the halfshafts? Lots of miles on this car and never replaced halfshafts.
Any insights would be appreciated!
