BILL2232 Posted February 4, 2004 Share Posted February 4, 2004 My 99 Legacy, auto tran, developes a slight vibration after driving at highway speed for 45min or more. It happens intermittently and goes away if I slow down or stop. I have eliminated brakes, roters, front end, and tires as all are fairly new and I have rotated the tires. It only happens after driving for at least 45min on the hwy, but not always. At low speeds, no such vibration, and the front end is tight. Any suggestions?

99obw Posted February 4, 2004 Share Posted February 4, 2004 Just a WAG, but our outback has a vibration around 30 mph that I think is the front diff bearings. Try and wiggle the CV joint where it enters the transmission. How much does it move? What is the general condition of the axle assemblies?

1 Lucky Texan Posted February 6, 2004 Share Posted February 6, 2004 OK - this might be a crazy idea - but I say its a tire. Most every other item will either be cool (like the brakes/rotors) or pretty hot very quickly (like 15-20 minutes) on the freeway BUT tires might take 45 minutes to get warm. Do you feel it in the steering wheel? How is it perceived? Quote Link to comment Share on other sites More sharing options...
BlueTrain Posted February 6, 2004 Share Posted February 6, 2004 well, perhaps the wheels are out of balance. oh, and is it the same section of highway? i know this may sound dumb, but perhaps certain sections of the highway are of a different texture. i recently did a 4000 mile trip in the loyale and when going across north dakota, there were certain rougher (not torn up, but just rougher texture) sections of the highway that got the rig vibratin a bit... just a thought....
