Chasing down a rattle/ chirp/ squeal noise

Any ideas? Sounds like it's coming from the driver's side when I let the windows down but that could be because I am sitting on that side.
Around 1700 rpm, sometimes right before idle slowing down. Makes no difference if I shift to neutral or whatever. I am thinking idler pulley? Brakes seem to have enough pad left.

 

grease the whole chassy

 

Good luck with this. I have a similar squeak as well, sometimes it sounds like it is on the passenger side, but then it sounds like it's on both sides, sometimes it's louder if I roll the windows down sometimes it doesn't.

I'm starting to wonder if my issue is the body mounts being dry. It is possible I have some metal to metal action going on at the grill though so I don't know.

As for you, it may be something else. It would be best to state what sort of chirp noise it is and whether or not it sounds like it's metal on metal or not.

 

Pull the belt off and spin and feel each rotating pulley.
2011 could be all idlers and tensioner , AC comp, alt, PS or not.
Or simply quess away or just wait and it will get louder and more obvious.

 

If it sounds behind you Check your carrier bearing. I started getting one recently and yep that sucker is toast. A common failure on 2nd gens too. If it's the front then yah pulleys and such. I'm with @muddog321

 

Mine was a bad alternator at 125k

 

Narrowed it down I think, the reason it was so odd is it was 2 noises. A faint squeal coming from the front turned out to be an idler pulley and a chirp coming from the rear I can prob assume it's the carrier bearing.
I ordered a carrier bearing and it hit the doorstep today, what's everyones thoughts on replacing the u-joints at the same time? Should I do all 3 or just the rear or wait for them to go later? Truck has 120,000 miles now.

 

I only want to pull the driveshaft once.
I would do a 3 at the same time. If one is bad, the others are probably not far behind.

 

Is it rotational? Is it RPM or speed based? Greased U joints regularly?

 

Factory u-joints are non greasable

 

I need to replace my carrier bearing and u joints. Is there a brand i should go for?

 

I bought Spicer

 

If you are doing the carrier spend the 100 or so on 3 greaseble spicer joints and replace them all considering you will have the tools to take apart one joint to do the carrier

 

I have always liked spicer.

 

worn exhuast doughnut to muffler makes some squeek chirp noises when slowing down that not fun to pin point, go shake your muffler input under the cab

 

What about the carrier bearing, what brand should I get.

 

Spicer for sure
