Hi, sorry to start another thread on this but this noise is really getting on my nerves. I have an 02 Sierra 5.3 ECSB btw. Every time I accelerate or decelerate suddenly it will give a quick loud chirp or a series of chirps. I hear the odd chirp when I hit a pothole, but its mostly at start and stop. I have been searching around the forums and it seems that the most common cause is either the leafs or the shocks.

Any advice on how to pinpoint the problem and permanently fix it?

 

Do you have side steps, my squeaks come from there and im going to the dealer to see if they can do nthing about it.

 

I do have side steps, never thought to check there. Ill take a look at them this weekend.

Thanks 5.3

 

You may want to check your shackles. They squeak a bit when the bushings get dry.
