Default Rear spoiler noise: It's not the bearing!


I bought the bearing (all of 6 Sfr), did the full routine, dismantle, clean, change, grease and glue.
Refit everything and triumphantly activate the switch: SCREEEEECH!

Oh crap! It is the electric motor that odes that godawful noise. Makes me want to torch the thing and block the spoiler in the open position.

Seriously, anyone have a solution for the noisy *motor*??

George can a person of your talents not rebuild the motor or is it all sealed up?

I have not looked at it yet, and I wish someone has gone this way before. The motor is over 400$...

If you disconnect the motor from the cable shaft, and operate the motor. Does it make a noise? Trying to isolate where the source of the noise is.

Good idea. However, I cleaned/changed/greased everything but the motor, and when putting my palm on the motor as it works, the whirring seems to come from it.

I've been looking at opening the motor up for a while but have been trying to find a broken one to play with first just in case...

I'd be interested if anyone has cut the motor in 2 as I'm guessing there is a bearing in there which has gone the same was as the drive

The motor halves need to be cut apart at the seams. Be careful about cutting and damaging the unshielded inductors at the far end of the motor. I rewound the lower one because I cut into it - it's 20 AWG mag. wire but I only had 23 AWG and went with that.

The motor is a RS-545RH and the one bearing is a SKF 625

Ok I'm having a go at this but can not remove the brass worm gear from the spline on the old motor, any ideas?
