I had the passenger side idler pulley start grinding on me a couple days ago. When I removed the pulley, the bearings fell out into my hand. Knowing that the idler pulleys on the 1GR-FE are suspect, I changed all three. This was my 3rd complete set of pulleys in 115K miles.

I don't know if they were posted but here are the NAPA part numbers.

The upper pulley: NBH36173
The lower puller: NBH36174
The passenger side pulley is the same as the upper: NBH36173

Wow! Wish I would have looked into the forum before going to the dealership! :mecry:

I went mudding through a few decent creeks recently, had a great time, rinsed the FJ down along with a light rinse on the engine. Guess what? It had that diesel sound for the next week! :flame:

My friend and I came to the conclusion the it might be the pulley. My FJ is under warranty so I took it to toyota. I went to the dealership who decided they wanted to replace the water pump, the pulleys, and the belt. Guess they wanted to squeeze every bit out of that warranty!

My baby is used with 71,000 miles so I couldnt say no to free parts and install! Got it all for only $50. :rocker:

They put stock pulleys though, so I will definitely be buying the aftermarkets for next time!!! :bigthumb:

sounds like i've got this exact problem (THANK GOD ITS NOT TRANS PROBLEMS :| ) went wheeling with the local jeep club (no fj club in my town) and we were puddle jumping for atleast 30 min straight.. constant whine in park rev and driive, and follows rpms, will replace with napa ones asap, hopefully part numbers at napa are the same in Canada

Part numbers are very similar... just off by one of the letters I believe. If you have a good counter person they should be able to figure it out.

07 with 120K miles on stock pulleys, no noise. wondering if I should do this when I change my belt or wait until they get noisy?

I would wait if no symptoms, or damage to belt. I had the same idea as you (except I had lots of squeaks), and went to replace pullies, and ended up replacing all the pullies, belt, and belt tensioner where if I just left it alone, it would have continued on with a few squeaks. Don't fix what ain't broke in this case. If your belt starts going, you'll have plenty of warning IMO if you monitor it visually on a regular basis.

On the other hand, a belt is cheap and simple to replace, so if you are DIY, do it. The lack of current issues should make it more straightforward than my situation.

I would recommend an OEM belt after going with Gates myself.

G'day,
I actually carry a spare belt with the FJ permanently, just incase .... :lol:
but having only 60k miles on the FJ, it should be good for a while yet.....

just swapped it with a new Tacoma belt. fit just fine, and now I got a spare (my old belt looked surprisingly good for having that many miles on it)

Hello to all as this is my first post. I have read the multiple threads on this and you are all very helpful. So I purchased all the pulleys and the belt and was ready to replace them all. Then I remembered one member mentioning that WD-40 got rid of the sound when the belt was sprayed. It didn't make much sense to me but I thought that maybe some of the WD-40 got on to the thread bolt which holds the pulleys and got rid of the noise. So I tried it, directly spraying onto the 4 bolts securing on the pulleys without getting any on the belt. Guess what? The noise is gone!! I don't know how long it will last but it may buy some time for some of you with milder issues. Just my 2 cents.

Back in the day when I had a rusty old Chevy pickup... one of the pulleys squealed like a SOB.... I pushed a bit of grease into it each day/week for a while and it eventually stopped... for good! :lol:
(a bit more room to work on that motor than the FJ though )

Bumping an old thread here mainly because it was so useful. I replaced all the pulleys in my 2007 last night using the Gates pulleys. I installed the 36174 on the tensioner and am wondering if the 36173 would have been a better fit. Comparing the old pulleys, the backspacing on the 36173 looks like it might match better than the 36174. I suppose time will tell. The belt goes right up to the inside edge of the pulley. I felt around and it doesn't go over the edge but is pretty close. I noticed the upper left pulley does the same. I installed the tensioner pulley without the insert that came with it. I also learned that my torque wrench doesn't torque turning counter clockwise. I'm lucky I didn't snap the bolt off.

I'm glad this post helps. I have to point out one thing I did not mention in my original post... Take note of the bearing insert in the photo above the bearing:

When squeezing your arms around the fan and hoses, it is possible for you to screw the bolt in and the insert comes out, rides on the bolt and you think the bolt is tight. Be sure to visually inspect that the insert is inside the bearing before you tighten it down or you will damage the bearing. I almost made that mistake and caught it at the last moment.

At the angle you are working it is very easy for this to happen and that would spell disaster if you started the engine.

Just an FYI.

Enjoy.

Bushing insert goes on back side or front side of the pulley?

So...... did everybody decide the Gates replacements were actually sealed? Or did Toyota start using better bearings? Mine is an 09 and still good but would like to get ready!

Old thread, I know, but I've got a 2013 TT with whine from the engine bay. Is it likely that it's these same pulleys? Easy fix? The Toyota dealer I just bought from said it's a normal sound and the drivetrain is perfectly sound.

 

[DEWFPO]

The alternator could also be a source of whining on these engines.

 

[norm356]

PAKraig, first find the source of the noise. Use either a mechanic's stethoscope, or a long wooden rod you hold one end against the housing or fastener near where the bearing is and the other end to your ear. A loud bearing will show up pretty easily with this test.

As DEWFPO pointed out, don't forget to also check for noise from your alternator bearings, etc.
