Got a problem with my 95 blazer. When I start up the car in the cold i hear a loud, humming sound from the rear end. I had the same problem 2 years ago and the shop replaced a compressor or pump that was supposed to level the truck with different load. I do not know the correct english word for this parts since I live i Norway (anyone who can give me the correct name for the part?)
They replaced this pump and the car has been fine since then but now the problems is back. The changed this thin on warranty and I will off course demand a new part. Just wanted to know if this is a well known problem and why this thin keeps failing!
