Last Saturday while pulling a bay boat in my '04 EX, I was noticing increased road noise when I wasn't in the accelerator. Anytime I was coasting there was road noise similar to when you are driving on a grooved road. I took the boat home and did a test run with no load and the same noise. I've checked all the tires, Trans temp is 161, and it doesn't sound like exhaust. Has anyone had this happen to them? I have about 8000 miles on Michelin M/S II's E.

My thought/hope is that I have a tire that is separating, but I've never had this happen before. Another thought/(hope not) is rear end trouble. My wife thinks the sound is coming from rear half of vehicle, but I cannot tell.

 

Does your drive shaft by chance had the center support bearing?
If it does You may want to have a look at it. While you under there check
the diff oil level and color after a drive around the block to mis it up.
Milky or silver are bad without even looking hard. If you find it low top it
off with the correct oil for your diff.
