Now let me preface this with- I know how to install blocks, as any monkey can do it. The squealing didnt start immediately after I installed the blocks, but I feel the sound is associated (how? I have no idea.) It seems to really squeal and squeak from a roll to a few miles and hour, and usually from an incline or decline at initial start up. My driveway is sloped as is my daughters day care and it sounds horrible. I'll try to get a video now, but don't hold me to it.

Thanks in advance

Work? The clunk is my releasing the parking brake

 

I can't make the video play. Upload it to youtube.

 

Sounds like a pad/rotor issue.

This work?
I really can't comprehend how it could be the block, as its stationary (or I sure as hell hope it is)

 

I'm sure the monkey used new u bolts when you installed the blocks, and made sure the locating pins are lined up? Squealing is probably from the leaf springs, or u joint. Since the block have changed the angle from stock. Check if there is any rubbing on the leaves, by the forward poly pin on the lower leaf. If so try some graphite to see if that stops it.

Worse case your u joint is binding and causing noise, check for rubbing and hit with lube, if that stops it then you have a problem.

I went though all this when I lifted my jeep. If stumped have a friend slowly drive your truck forward while you are close to the area of concern. Please don't get run over.

Also do you engage your parking brake every time you park? Since you have a sloped driveway?

Also I noticed it looks like you have red brake calipers "sp" were these installed or painted at the same time the blocks were installed?

Good luck

 

brake pad wear indicator ? Look at the back inside pads.

 

Have you tried jacking the rear end up, and relieving the suspension, then try to recreate the sound? Just an idea to isolate the possible issues.

 

I painted the calipers with a kit (brush) while on the truck. Yes new ubolts and the pins are lined up. It's at the dealership now for my new evap core and they are taking a look. Thanks thus far. The truck has 22k miles so I sure as hell hope the rear pads aren't hitting the wear indicators. We shall see

 

Some that drive hard in corners ( say heavy traffic and lights along with icy conditions ) wear the rear brakes especially hard due to traction control. They don't have near the pad size the fronts have if they are used a lot more. I have seen some early than you would expect from past experiences. With traction control those rears energize anytime there is handling. Everytime you jump over a lane or swerve slightly they will assist.
