Ah, got it! A picture may be worth a thousand words, but a video tells the whole story.

It was lubed on both sides. But perhaps just lubing the cage side, with easier access, will be sufficient and is worth a try before tackling a bigger job.

Thanks as always!

 

Worth a try!! I just dont like repairing things for the second time. Might have tried this if I had known what a pain it was going to be though!! When I installed the new motor I added a couple small drops of ZZDP (High Zinc oil additive)... This helps protect the bronze bushings as it gets into the pores of the bronze. Just a couple drops, let sit for a hour or so then spin the motor by hand and add a couple more drops spinning it after that. There was a noticable difference in the effort it took to turn the motor after the second application of the ZZDP. Zinc is amazing stuff for protecting bronze bushings. I add ZZDP to every vehicle during EVERY oil change. In the Rover I run Rotella T6 5w40. In my Infiniti I run Motul 5W30. Off topic but I figured that I would share!

 

@ThorInc Did you get to this project yet? I am planning to do it this weekend.

I found another video that shows how to remove the wipers and cowling:

 

Yes I did. You will need a long straw to apply the grease into the hole you drill. You can MacGyver one. Easy job.

 

MacGyver? LOL! https://www.dailymail.co.uk/tvshowbi...eaks-down.html

 

I never got around to lubricating the blower motor bearing. But I did figure out that the noise only happens during the colder months like right now (40's - 50's F). It was quiet during the rest of the year.

 

Five years later ... I'm finally getting around to this! Buying an extra long drill bit today. Stay tuned.

 

It may not be the bearing. You may be missing the retaining screw on the motor side, which would allow the hamster wheel to move slightly and rub against the cage. In my case, a mechanic had left it out and the fan only made noise when i made left turns (shades of NASCAR).

 

I have to remove the cowling to diagnose a problem with my engine cooling fan (not getting a PWM signal at the fan module harness connector, so I need to do a continuity test from the ECU for the PWM control wire). While I have the cowling off anyway, now is a good time to try this potential solution for the blower fan noise.

 

Are you sure the PWM is generated before the fan module, and not by the fan module itself?
