This thread is definitely an embarrassment for T4R

As have been a few lately...
Instead of a noob 15 reply wait to post I think maybe there aught to be a max of 3000 posts period. After that, forum regulars almost always turn into trolls. (Here and everywhere else)
As for /exactly/ what might happen when it breaks catastrophically I don't think anyone really knows as I've not read of anyone having that happen. Though several people have had a cylinder fail (leak) and had to have it replaced for 3-4 grand.
But to hazard a guess, I doubt it would strand you any where. At worst, may just be like not running with sway bars at all. In the end though To sell or be safe in the long term I think you would have to fix it. Driving with no sway bars is not really safe at all. (Wind, high speed cornering, dodging an accident etc. can throw you out of control a LOT faster than with it)
