Hi;

Have a 1994 4Runner that needs one front sway bar bushing replaced.  

There are "upgrade" kits that make this claim:  "Polyurethane bushings are
made to last a lifetime."   They (MAKO) claim rubber bushings don't last.
This I have found to be true, especially if you drive 1 out of ever 5
miles in the dirt, as do I.  
Polyurethane is a plastic.   So my question is, has anyone had experience
with this aftermarket "upgrade"?

Thanks,
