I've been battling this issue for YEARS. I've replaced the bezel several times, repaired them, reinforced them, tried climbing in/out of the truck ninja style, and no matter what those two long tab thingys would break off. As Rick Latimer once said, "NO MORE!"
I had the drivers seat apart to fix some other things and got to thinking - instead of two dinky phillips screws, why not some all thread? So I bored out the dinky screw holes and used all thread. I think I used (2) 4" lengths of 3/8" all thread with nuts,/washers/lockwashers on each side and then I grinded down the excess on the outside. I don't know if I'll do anything to make it look better but to be honest I don't give a crap how it looks, anything is better then having the controller and lumbar thingy dangling around down there.
Now what could be the root cause? Someone said that the padding from the ass part of the cushion is what keeps pressure off of the bezel which does make sense but I've seen some broken bezels with seats that had pretty decent padding. I thought that my big ass (240) was causing it since I did have to weld the lifter brackets that broke but some of the owners that had broke bezels weighed half of what I do so that kinda rules that out. I'm thinking crappy design since they did change the bezels in the later years but then again I've seen some of those broken as well. Regardless of the root cause, this is what I did to try to keep it from happening again. If it breaks again I'll update this thread. Also, the lean back function of the controller still works, there is enough clearance between the recline switch and the nut.
