Okay guys. My '99 Cherokee has been having a howling noise as I drive it since last summer. The noise gets louder almost in unison with my speed as it goes up. However, I happened to notice recently that the howling is deeper and more pronounce when I turn right. So my guess is left wheel bearing?? Anyone else had similar issues? Also, I have a coolant leak somewhere by the left side of the radiator. I have noticed it seems to leak faster during the colder months. The radiator was replaced at 100,000 miles and it currently has 143,000 miles now I usually top off the holding tank about once a week. Neither one of these is a major issue right now to me. I am hoping to address them when the weather warms up as it's pretty much too damn cold to work on anything up here in Iowa! lol Any help on pinpointing the cause of either issue would be greatly appreciated.
