It all started today, I noticed a squeaky noise and I thought it was my brakes but overtime it happened intermittently while cruising but extremely faint. And then during deceleration without pressing on the brakes, about 35 mph the squeal is louder.

I researched and found out it could be the wheel bearing but I'm not exactly sure if that's the case cause my situation is a tad bit different. Not sure but it could be. I see videos that it could be the brakes.

IF it happens to be the wheel bearings, is it fine to just retorque the axle nut the 250lbs to prevent it for now? It doesn't sound like the usual rumbling noise that wheel bearing problems have.

 

That will help slow the wear process, but ultimately it will need to be replaced if that is indeed what is causing the sound.
