intermitent hum through steering column
W124 400e 62K (already had my 60K service) - I've been having this intermitent hum though my steering column. It seems like it could be the powersteering pump or the water pump. It was happening only when I'd make right turns from a stop and even at that it was only occasionally. Then I noticed it would happen after a long stint on the hwy, once I'd pull off and had to stop. Then as I would pull away I'd hear/feel the hum. It went away for almost a month, but today on my way home, I heard it again just a couple miles after getting off the fwy. My belt tensioner and power steering pump have been replaced within the last year/10K -
Any input? Am I on the verge of yet another $$$$ repair?
