Looking for some insight on a noise in my 8.8. Some history on the 8.8. Its from 87 or 88. It was in a 86 that I had that was changed to 5 lug. Previous owner put new axles, drums, brakes, axle bearings and seals. Still had the original 2.? gears. I had new 3.73 gears put in it. Was a FMS kit with shims, bearings etc. I put about 3K miles on it. Sold the 86 with a different rear end in the car. I pulled the axles and drums from the rear end to convert the other rear end to a 5 lug. Over the winter I put it in another car that is a 4 lug. I bought new 4 lug axles, and drums. Install went fine. Now I am hearing a noise when off the gas and in neutral cruising say 30-55mph. The noise it most likely there all the time but I can't hear it above the exhaust noise. It's between a low drone and a humming noise. Not to loud. When I touch the brakes it goes away. So I thought maybe the brakes may be dragging a little. So I backed them way off, but still hear the noise. I can't imagine it was there before so it must be related to something I changed. Sorry for the long post. Thanks.
