hmm, seems I have a different problem than a noise issue, my rear spoiler is now not raising at all at 80km/h, only when it gets to about 115km/h thanks to the backup sensor.
It also wont open using the remote switch.

I would check the basics, when you engage the remove switch, to you get power at the electric motor? Are your fuses good? If you have power at the motor, then I would suspect your electric motor is faulty. You can test that by applying power directly. If no power at the motor, then you may have a faulty controller or broken wire.

ok so I checked the fuse, OK, then started on the spoiler motor, unplugged the wire, plugged it back in, checked spoiler operation and it works now.
Maybe the wire was loose or something. I did discover from looking at the spoiler curtain and other pix on what its supposed to look like, that its lost the top bit at some stage...

I replaced my crunchy bearing over the weekend with :
Nice quiet and smooth operation now. All I can hear when the car is off is the electric motor and can't hear it at all when the car is running.
Prying apart the plastic was a little scary. I thought for sure the plastic was going to crack, but it worked out. Just tried to be patient with it.
I used some Loctite 60 second universal glue and trigger clamped it shut. We will see how the glue stands up to the heat/cold over time.
Thanks for the DIY write-ups! Very helpful.

Great news.
Super glue will probably not last. I would recommend using two-component epoxy glue.

Replaced the bearing on a previous 964 a few years ago. Bit fiddly. Found the bearing details (a pretty common bearing) and picked a few up from an engineering store. Think I only paid a couple of pounds £ for them and got a few, kept one and gave the rest away. Image below identifies the bearing.
Agree with Tore - superglue doesn't hold the housing halfs together for long. Proper epoxy glue the right choice.

I use slow-curing epoxy glue with very good results, none have failed. It is very important to degrease the housing halves before glueing. I let it cure for 24 hours under pressure, and use several spring-loaded clamps along the edge.

For an application like this I would PC Auto bond.
That stuff is slightly flexible after curing, can handle extreme heat and frankly is the best I've used on cars for any kind of gluing repair. Of course it is still required to do proper prep - I would say that is the most important thing for a good result.
