I have a 2001 4x4 Blazer. Once the truck has been driven for 5 to 10 minutes, i randomly hear a squeak when coasting or while pressing on the accelerator. Any time I press on the brakes things are very quiet. I checked brake pad wear. Both pads have even wear and appear to have plenty of life left. I changed the brakes last summer and the wheel bearing was replaced by a dealer 1.5 to 2 years ago. Several friends said it was probably the bearing, but I wanted a "second" opinion before taking the time to change it. I have checked the threads about wheel bearings, none seem to have similar symptoms.

Any thoughts?

 

I have a similar problem that is probably a broken or loose engine mount... except my noise is more of a grind on hard takeoffs (merging, etc).
Check your engine mounts and make sure they are tight.

I you have a wheel bearing going out, it will likely roar insted of squeak.
