I have an '08 and the new pulleys were the right size (no adjustments needed). It was a very straight-forward process following his directions. The only real pain (for me) was getting to the bolts on the AC compressor.

Hi
thanks for that is good to know ,my bearings went bad a long way from home so i found one bearing and the other two i cleaned up and put grease inside by pulling back the cover and pushing the grease with a pin ,put them back and got 1500km back to home .mybe good to know too .

the way is the other way !

Re: Idler Pulley/Bearing Failure, what to do:

Are the compressor and alternator removed to allow access to the bottom pulley? Great thread! I am going to be replacing mine soon, i was not sure if it is possible to get to the bottom without removing the compressor/alternator. I was curious as to why the alternator/compressor needed to be removed. Mine is making a very faint sound so, I will try to determine which pulley it is, I suspect it may be one of the top pulleys, those look to be easy enough to change.

Yeah. The compressor is literally bolted against the idler assembly. You HAVE to remove the compressor BOLTS and then you can leave the compressor dangling (off to the side) to replace the idler assembly. The compressor bolts are a MAJOR PITA!
Got it thanks! I'm going to start with the three pulleys and go from there. What is odd is that mine do not make noise often, once in a while. After reading this thread, I figure I may as well replace the pulleys to be on the safe side.

Thanks again for the response!

Re: Idler Pulley/Bearing Failure, what to do:

Alright, I have all the parts from RockAuto listed above. Removing the belt tensioner assembly seems like a PITA. My question is, can I just swap the pulley from the Gates #38411 onto the oem belt tensioner assembly?

Yes, you only needed the pulley, not the mounting bracket.

Do you drive thru very deep water or mud?

If you don't have any of the typical squealing noises, then I would just replace the belt. When you have the belt off, check each of the pulleys including the water pump and alternator for smooth movement, no wobble or any unusual noises. If all is well, install the new belt and be on your way. If one of the pulleys is going bad, replace all 4. I wouldn't touch the water pump or alternator unless you are having obvious problems. They are not typical maintenance items.

Just change the belt, but don't buy the new one from Toyota. They charge like $90 plus shipping for an FJ belt. You can get an excellent Gates belt which is as good or better than the Toyota one at the amazon link below for 1/3 the money or check your local parts store.
