Yes, thank you. I posted lite grease because you should not use any of the thicker types or wheel bearing grease. I will pull the unit again after awhile and check on the bearings. I tested it before reinstall and its super quite except for the silly vacuum cleaner sound.

Nice DIY. Thanks for the instructions. I was planning on pulling apart my SAI and this DIY helped convince me it was worth the effort. I used Teflon bearing used for bicycle bearings but I may replace with Mobil in the future. Using a syringe was a great idea idea.

I also used a compressor to clear out some of the dust in the motor and it might be worth recommending. The amount of soot that blew out of the motor was pretty significant.

Great DIY write-up! Mine is whining so this is on the cards for me. How long does it take from start to finish? I already ordered the Mobil grease from Grainger, but need to find some time to work on this one.
