I've got a 99' maxima 5 speed, with just over 110k. It has been on Eibach springs since the beginning. I've got this gradually worsening noise/vibration. Think of the sound a bowling ball makes on a lane as it rolls. Now take that rolling noise and pulsate it. The pulse increase with vehicle speed, and it will come and go, it isn't constant. The problem is more noticeable at low speeds and when I first start driving. I can't detect anything over 50mph. It increases with vehicle speed - which makes me think it is either a CV joint, diff output bearing, or wheel bearing. Upon first looking into it, I found grease slathered all over my pass wheel well. DING DING DING - bad pass. CV. So I take this past Saturday and replace it (total PITA btw). Wasn't fun replacing heavy, greasy parts with one arm in a cast. Get it all back together and the noise is still there. WTF? Jack it up again and check the FR brakes and bearings. The hubs spin freely with no odd noises when the calipers are off. Then I find that the driver side slider pins are seized. That HAS to be it right? It took a torch to get one unstuck, but I get that fixed. Still making noise -So, what are your guesses? The driver side CV is an 8 month old rebuilt unit. I noticed a pin hole in the boot and grease spread in a concentric circle. Could that be toast already? -Could be the diff bearings (common problem on maximas) - however the trans doesn't leak a drop. -Wheel bearings? 110k seems a little early for that right? Hubs seem to spin nicely.
