Not trying to add to your problems and I'm sure someone was trying to eliminate the squeal... but that white lithium grease sprayed all over the rack will cause problems down the road as it attracts dust and dirt. Clean that off and use a good 'dry' spray with PTFE. Something like **THIS**
I have used a "dry" lube for years on my RV's. And what you linked is exactly what I use on my slides and my garage door. Being an old farmer here, I know the problems that good ole grease creates. It attracts dirt like a magnet! The Lithium grease was there when I purchased new. In fact I pointed it out in our PDI. Of course there were all kinds of excuses and reasons and on and on...now I know why it was there, to quiet the noise.
You are right on enlarging the hole, that is my next step as stated in another reply.
The slide seals well, so next option is follow the "travel" of the actuator back to "retracted" and see how much room I have to enlarge the hole in the plate.
I will drop the enclosure on the belly and make sure I will not start a fire inside and start my grinding and see if I can get a little clearance. I hope it will not take much.
Searching the web, I have found others with this problem and most went back to a broken or twisted mount on the back end of the actuator. The actuator was actually over extending the length of the slide. I will look at that also.
I want to thank everyone for their comments and thoughts. I welcome more if they come to mind.
