hi.. i have a question i have a 1993 mercedes 300 se and im getting a vibration from the drivers side rear. so i jack the car up and saw the left rear wheel is shacking/vibration at about 2000 rpm only. under 2k no vibration and also i hear a clucking/clicking noise while driving. front flex disk is bad will this cause the rear end to vibrate like that. im just wondering if it might be the rear axle are cv joints are bearings please help me with this one thanks.
