clunking noise on front wheel
Thanks for the support and the heads up on _not_ jump starting (I would have never guessed!)
While I am at this I will post a previous problem I have had with the car. It has been solved by dealer under warranty a few years ago, but if anyone has this issue, you may have the same headaches as I did...
Problem occurred at about 50k miles. A light clunking noise in the right front wheel area. Sounded like a bushing went bad on a sway bar or such. It starts clunking on some bumps in the road at low speed, or when accellarating from a red light, as if something is trying to "adjust" to the tension of the accelleration. Ofcourse the kicker was that the problem was very intermittent. Usually that means it always does it for me, but never when you bring it in to the shop.
It was brought in for repair 6 times. The dealer changes shocks, swaybars, and just about everything that holds the right wheel to the car. Nothing fixed the problem. Finally, when my warranty was coming to an end, I told the dealer to just keep the car until he fixed it. Ok, I should not have said that, because he had it for two months, and then finally found the problem.
The culprid was a loose pump and valve on the pressure system of the right wheel suspension. The noise would _only_ occur when the pump was running (the virbration caused it to clunk). This made it very difficult to find since the pump only runs on occasion when the suspension needs pressure.
Just about drove me nuts to get this fixed, but in the end it worked out. I got it fixed under warranty, and MB gave me a $2000 credit for the inconvenience of not having my car for 3 months because of this issue.
Anyway, if you have a similar clunking noise, you may want to check this...
