Scott and list. May I suggest John Cash's "I Walk The Line" to check and see if the hum is in tune. Also need to see what key the hum is in, as this maybe related to the "whine" of the tires (depending on type, size and if the original rims are used or not) on various pavements, which could be affected by the height of the car (original shocks vs. lowering kits) in relation to the cross wind speed. Every once in a while you get the chance to have a little fun with a post. To the original poster, hope the others have more important input than mine. I just couldn't let this post die without having a stab at humor. Bruce Battles Vin# 6569 [Non-text portions of this message have been removed]
