Edit: I was going on a generic image of the MT64 series so we need to confirm with an actual 200-series application picture. /edit
In short the lack of an outer sleeve in the bushing around the post for support means forces are applied in ways Toyota didn’t intend, so the mount post welded to the axle housing is bending significantly. Rear shock guards seem to exacerbate the issue to a large extent.. but the same thing doesn’t happen to any shocks that retain the sleeve. Ultimately it’s a poor design choice.
Otherwise these shocks look like a really nice option.. especially when you consider ARB’s policies around rebuilding BP51s or the fact that they often end up being non-adjustable anyway due to frozen valving adjusters.
Moving this topic from the LCDC9 thread to its own thread to get better visibility. @elkeye posted his damage (shown below) and then last night I was taking my shocks off and noticed similar damage. Not sure of the cause or how best to fix it but some speculation below...
