just wanted to introduce myself and ask a couple of questions. well, i sold my 03 land rover discoveryII and ended up with a 99 land cruiser. man, its kind of relief to get rid of my rover as much as i loved it, it was too often in the shop for something. anyway, i got a very clean 2 owner river rock grey with cdl. 112k on the clock, all scheduled maint. performed. i also own an 04 tacoma dbl cab 4x4. i love the cruiser so far, but have a concern. right at 70 mph it starts making a noise that feels like its coming from the drivers side front. it goes, mmm...mmm........mmm...mmm . i know that doesnt describe it well, but i will tell you that the tire is worn funny to the inside of the tire. i had toyota give it an overall inspection and the found nothing threatening. i plan on having tires rotated and balanced soon, but could it be something else like bearings wearing out? just give me your thoughts. thanks, -david.
