Drive line Whining

[Ron Randolph]

Hi, I'm new here, I have a 99 Silverado LS 2wd that I bought from a friend a couple years ago.  The truck had about 175,000 miles on it when I got it.  It has run great up until recently when It developed a noise in the rear of the vehicle. It is a whining noise that occurs during acceleration and stops when I let off the gas. Also, lately I have noticed sometimes when I accelerate from a stop it is sluggish up until I reach about thirty five miles an hour.  I have read somewhere that it could be the fuel pump or maybe a bearing, or maybe both. I'm here in Florida and I need to drive to Virginia some time this month and I need to get this fixed. Any suggestions would be greatly appreciated.  Thanks, James Randolph

You would have better luck on a general Silverado forum. This one is specific to the Silverado SS.   Your 99 pre-dates the Silverado SS by a few years, so the information here may not be very useful.
