Thought this was worth sharing to hopefully save anyone who's not sure if they should put some sway bar re-inforcement plates on their Sdub.
I never considered it a high priority as all I'd ever seen was pics of cracks around the mounts.
This is what happened while I was driving around with my suspension set on stiff and good semis front and rear...
Ripped the sway bar mount right out of the chassis

 
This was the bit still attached to the sway bar, there was a chunk of metal completely missing from the chassis rail

 
Patched up the missing section

 
Patched with a knocked up replacement piece running down the left. (those welds were ground flat before the reo plates went on!!)

 
All finished and re-inforcement plates mounted

 

 

 
The drivers side mount had cracks all around it also, so it was welded up and ground back too.

 

 

Hah, good post. Ill sticky it if noone else does, or maybe get it put in the tech section as vital info

Wow!
What sway bars are you using?

Did that happen when using an aftermarket sway bar or factory??

Factory sway bar, thats one of the reasons I never got around to the reo plates, everything I've read seemed to imply it was only a major issue when upgrading sway bars!

Factory ones can't be that bad then.... :)

neither are the semi's.....!
Wow! 

Do the later models come with some sort of reinforcement from the factory or do you need the plates for all sw's? 

pretty sure the later ones are different and stronger.

Maybe a good idea to fit them to the later models anyway just in case.
They don't cost that much, so good insurance.
