I have a 99 Tahoe, its on the way to being mechanically finished, Ive noticed a noise kind of a clicking or grinding sound that comes from underneath , cant tell for sure but sounds like its under the front or middle. Ive changed the U joints and fixed that issue, it went away somewhat after doing that, but now is doing it alot. Im kind of new to Tahoe ownership, so any help would be greatly appreciated, Im hopeful it is an easy fix. Thanks, in advance.
