maybe coil compressors
What about people with Avalanches or Tahoe/Suburban with rear coils?
My burb has rear coils and I get the yoke clunk every so often. I just grease the shit out of my slip yoke when it starts clunking, and then it stops for about 6 months or so then the clunk comes back.
Then I believe your only options are to either grease it like you already do or ge the updated part from GM.
