Yep. Not a fan of the pretty aluminum covers because of this. Like I said earlier...remember that magazine article in 4-Wheel & Off-Road in 2003 or so where they took all the popular covers of the time and mistreated the hell out of them? ALL the aluminum covers failed badly.
The aluminum covers have their place. I plan to use those T/A covers when I get some spare coin. I'm not going to run my sand drag blazer against rocks.
However, if I were to build a rock crawler blazer, I go with one of these.
It has the strength of the fabricated steel covers and load bolts for the bearing caps.
