Sometimes when I am driving I hear a strange sound almost like a low moaning sound, especially when I turn my steering wheel. I have a 92 400E (114k) and the maint records show the steering pump was resealed once prior to my purchase. I have had the vehicle for a year and I had the auto shop check the steering pump they saw no leaks but they resealed the pump for free since it was still under warranty from the last reseal. There are no leaks that I know of and the steering fluid level is fine. This noise comes and goes? HELP...
Second question, I was wondering if I kept this 92 400E with 114k miles well maintained how many more miles does this car possibly have?
I enjoy driving this automobile, I truly love her...
