Just started making creaking sounds. Thought maybe the spare tire was loose. Is not. I am not a mechanic. Any thoughts so I can look and learn what might be the problem?
Thank you.

 

sounds like you busted your rear end but where is the sound coming from?

is the truck drivable ?

 

Yes. The Blazer is driveable. It sounds like something underneath needs to be cushioned b/c it makes the creaking/rubbing sounds the whole time I'm driving. I can isolate it only to the rear of the Blazer and coming from underneath.

 

I found out it is a broken spring shackle.

 

good to know you found the problem
