As part of my wiper regulator overhaul, I dissembled the wiper motor and when I put it back together it is noisy. I am not sure what did wrong.

I removed the motor casing for inspection. I removed the two securing tabs and pulled the cover off. As I did this the main rotor pulled free from the brushes and the main bearing at the top pulled out of the seat.






When I re-assembled, I made sure the brushes were re-installed correctly and the bearing was properly aligned when I pressed it together.


I'm sure it's got to come out but not sure what to look for. Tips appreciated.

its possible one of the thrust washers has slipped off of the shaft

Do you have an exploded view of that? I didn't see any in there

Closing out on this thread. MrMerlin, happy belated B-day, and thanks for the link the post. I used that to re-dissasseble the motor and I was able to determine the little rubber stand-offs that support board that house the magnet bushings were not properly seated in the motor cap. The result was the magnets were rubbing against the rotor coil wires. I was able to encourage the rubber posts into their holes using some Deoxit lube. I tested the motor and it was much quieter.

I also noticed the set screw on the top of the worm gear shaft can adjust where the magnet bushings are aligned on the shaft.

All better now, thank you.
