Thank you to everyone for suggestions about PM on my new car.
I forgot about front wheel bearings. They were replaced (?) less than 10,000 miles ago. I looked at the receipt from the previous owner. He went to the dealer complaining about an overheating right brake. You should see the list of parts they put on it - including calipers, brake hoses, assorted brackets, and front wheel bearings. Why would the wheel bearings have to be replaced? Isn't that unusual? >From all the suggestions - I did figure out a few things I need to do. Replace ALL FUSES and service rear diff. There is a guy on ebay selling complete fuse packs for Mercedes. He says his fuses are all brass rather than aluminum. Is this a bogus claim of superiority. I haven't looked at my fuses in a while, but I thought they about half of them were copper. What gives? Donald H. Snook 1990 300SEL
