I couldn't find any information about lubricating the bearings on my
1999 Intrepid. Is there anything I should do for maintenance or are they "permanently" lubricated? Also while I'm at it, is there anything on the car that needs attention from a grease gun from time to time?I've noticed a slight sound from the left side that is only noticeable inside the car when the window is open. It is almost like a cricket sound and is proportional to the vehicle speed. I notice it above about
15-20 mph until road and wind noise overpower it at around 30-35 mph. Anything to be concerned about? I was even thinking that it could be the wind through the alloy wheels, but I don't seem to notice it on the right side, and I don't really recall it during the first years I had the car.
