1. Very loud squealing sound. I tried spraying WD40 on one wheel that guides/moves the belts, and it stops, but starts again within minutes. Would changing the belts fix this? I am thinking it is the belt that connects to the alternator as the battery indicator moves up and down. 2. There is a persistant ticking sound. I have heard about *lifter tick* and that it probably is not a major thing, other than the annoyance of the tick. Any input/suggestions on this would be greatly appreciated. Thanks in advance.
