1500 vibration or buzz

Postby dingdong » Mon Apr 23, 2012 5:20 pm



Out for a ride today and developed a vibration or maybe a better description is a buzz felt through the grips. It happens at idle in neutral or in any gear at any speed. More noticeable when revving or accelerating. In tracing it's location I noticed it is coming from the right side and when using a stethoscope I hear a noise under the valve cover that is louder at the rear #5 cylinder. At least louder that the others. Not really a ticking just louder. I'm thinking I might have a sticky lifter but I really have no idea. Any ideas will be appreciated. Thanks!

I've not felt that on mine,however another guy did have a vibration coming from his alternator bearings or bushings.I know it's on the other side,but it's worth checking.
Another thought is something at the timing belt area.There are two of them and one could have a noisy bearing in the idler pulley.You might hear it better when probing the front covers,behind the plastic.

Turned out to be the alternator. Rear bearing is gone. Seems a stethoscope isn't very good for locating vibrations. The old, long screwdriver in the ear, worked well for finding the vibration.

Take it to a repair shop and have a new bearing and brushes put in.Cheaper than a $200 replacement.
