Relay
Before looking at replacing the compressor I would check the simple stuff first. The Mag Clutch relay is where I would look first. I had to replace mine. Does the A/C light flash on the temp controls? Then I would check the fuse as well.
To see if it's the relay, pop the box under...
Have you seen the driveshaft clunk issue on here before? Doesn't quite match up with what you are experiencing, but worth greasing the driveshaft, either way, to see if it helps.
For sale is a ARB CKMTA12 dual air compressor with manifold and 4th Gen bracket. I'm trying to remember who made the bracket, I think it was Bandi? I installed this in the vehicle but never wired it up. Looking to free up some cash right now. I still have all the original wiring, button, and...
Springs
I have run both springs in mine. I was planning to get an aftermarket front bumper with winch. I have the V8 with a full skid package. Even without the front bumper and winch, I thought they were a little too stiff. So basically unless you have a lot of weight like others have said...
Broomfield
I'm in Broomfield, but it sounds like you have the issue most likely diagnosed. I use Toycrawlers here in Broomfield, but they are pretty popular shop so they might not have time to work on it. The owner is from Boulder Toyota so he knows his stuff.
Sticky caliper
Seized caliper pistons are very common on these trucks, and even very common on the 5th Gens since the design is very similar. There are a lot of threads out there on reasons why, and how to prevent future seizes.
Seems like most of the aftermarket calipers will last 2 years...
Ac
I would try replacing that relay. Mine went bad and the light started blinking. I know yours isn't doing that, but they are known to fail so it might be worth replacing before going down any other roads. You could jump the power so that the clutch always has power, but I wouldn't rec'd...
Fuse
I would use a multimeter to see if that circuit has any continuity to chassis ground. Basically, put one lead on a grounded bolt and the other on the circuit. If you DO have continuity then you have a short in your wire.
Lean
I have the OME yellow spacer that is 10mm. I think it helped, but with the front coilovers at the same height, the rear is still a little lower. I would go for the 15mm if I were you. You will probably still have to crank the driver side more to keep everything flat.
Mechanic
You might have to wait to get an appointment, but Toycrawlers in Broomfield should be able to take care of you. He told me recently that he has a welder come and do the work.
Video of engine noise
I was hoping it was an idler pulley or tensioner, but after listening more closely I'm thinking water pump? I'm going to take off the serpentine belt Sunday and spin everything by had to see if I can find the culprit.
