Guys looking for some advice. I have an 07' with 26000kms on it. When I get to 120km's (70mph) per hour I start to hear a significant humming noise coming from the read end area. The frequency of the rhythmic high/low humming is kinda like a wooow woooow. Forgive my description but I can't describe it any other way......lol It only takes place in while I'm in 5th gear in the 120kph region. If I pull the clutch in at that speed it stops immediately. I can't feel any vibration. If I downshift to 4th I can't hear it. SO I'm assuming that it's something it's not tire related. I've had the issue for awhile and I'm starting to avoid the 120kph region while I'm on the highway. Any thoughts would be great.
Dave
