Excessive play in x-axis linear module bracket

The mounting bracket on the linear module on the x-axis on my A350 is loose. The toolhead is tight to the bracket but the bracket itself now rocks up and down a millimeter or two. I couldn’t tell if there is a way to tighten up something inside. I tried opening the end like they suggest to look for the silicone pad, but they warn about messing up the limit switches so I didn’t want to go any further. I put in a support ticket, but would love to solve it myself. I could probably just swap out …
