I have this problem. Massive wear between the toolhead and the carbon rods.
There is about 0.3mm slop in all axes.
My question, to which I need some guidance, is what to replace. I suspect the wear is the toolhead rather than the carbon rods but I guess it could be both. 
Anyone been here before?
Thanks,
Gerard
To answer your question, the first stop I would visit is the wiki page on repairing the rods. This is chock full of video links and suggestions.
However, that is an alarming amount of wear. It suggests an alignment problem, either with the carbon rods or the housing itself. I’ve experienced issues with my toolhead cover on my P1 that eventually led me to remove most of the screws to eliminate stress on the housing, which was causing false “cover fell off” error messages—but nothing like what you’re seeing.
I can no longer find it on the web, but there is a alignment tool/procedure that someone came up with that ensures that the rods are square and plumb. The bookmark I had for it has been removed so it may be somewhere else on the web. It was an elaborate set of acrylic squares one could purchase online and then use to square off the rod alignment. Perhaps someone here remembers this, it was posted sometime in late 2023/2024. I would look at diagnosing the alignment before considering a replacement.
How many hours are on this machine?

Yeah, there is. I remember reading it.
I’m also getting a Lidar lens dirty message which is probably related.
