The fan pulley bracket has bearings in it that go bad. Mine did, almost taking out the radiator. Replaced the fan clutch at the same time as a precaution.
I'm at 203k miles. It's not a bad idea to switch them out pre-emptively, especially if you're planning to replace the belt and tensioner. I strongly believe this is what pushed mine over the edge and when it fails it may do the same if not more damage than what happened to mine.Hey, just curious. Approximately what mileage did your fan clutch and bearings wear out? Is it smart to replace these parts pre-emptively?
Yes! Buy OEM, the Gates one I bought loosened up after 20 miles! Replaced it today with one I picked from a salvage yard. Also avoid the Gates belt tensioner!Forgot to mention.
Don't buy the autozone bracket/bearing assembly. My roadside repair lasted 11 months and probably < 10,000 miles before it started making noise again.
Buy the Nissan one, or at least a reputable substitute.
Update on this: I've now had my 3rd bearing bracket fail. 1st was original. Second was Gates, 3rd was a salvage OEM. Not sure what is causing it. But it's getting expensive because every time it fails it breaks the ac condenser fan and the radiator fan.Yes! Buy OEM, the Gates one I bought loosened up after 20 miles!

Yes, it is the same clutch. I replaced that about 10 months ago. It appears to be engaging normally. I made a more detailed post a few minutes ago about the situation. Harmonic Balancer failed, bad aftermarket steering...Is it the same fan clutch on all the failed bearings?
Is the bearing pulling out or the bolts backing out?
No the problem started after I replaced my power steering pump (same evening on the test drive, then again three weeks later). My other post provides more detail about the problem. The power steering pump pulley is out of alignment with the idler pulley and the crank shaft. This evening I put my old power steering pump back in to check the alignment on that and it appears that it's off too so I'm stumped still. Wondering if the power steering pump bracket is out of alignment somehow.Problem started after installing a new clutch. Good chance the new clutch has an issue. Out of balance, wobble, etc. That would also explain the pull out issues.
New bearing and a new clutch (from a different source). Should fix it.
