few weeks ago the Blazer started making a kind of droning sound.
Not a gear to gear type of sound, but a kind of a deep pitched droning sound I can hear from inside the Truck. It starts at around 35-40 mph and continues until I drop below around the same speed range. The pitch does not climb
( like going up the scales on a piano), but stays pretty much a one note.

Was kind of thinking possibly the same thing that happened down a couple of threads on snuffy's Blazer maybe?

thanks in advance.

Blazer is 2004 and has 125K on the clock. 4X4 4.6 and has never given me a lick of trouble.
Always keep maintenance up on it and such.

 

you can spend the money if you want to that is up to you, but remember the basic teaching of noises, just turn up your radio.

It's the best thing to do.

 

yeah, got that right for sure.

Now, just need a good Clarion unit for sounds.

 

found the problem

hub bearings were fine

it was the front end alignment,
caster was way out causing the right front tire to start whining above 35 mph.

 

Glad that I could help. Sometimes when you have no idea what to say you have to say something useless. I am sure you will agree.
