I've never understood our hobby/industry's fascination with red urethane, especially it's continued use for many years for transaxle mounts and steering couplers. I know I shouldn't be- it's cheap to mold and work with and adds (what some people think is) a little bit of bling, so the VW crowd being the cheap a*sed idiots that they are, we get what we deserve I guess.
As has been said, with age the material always fatigues and tears, which while being a grand pain in the petootie replacing mounts every couple of years is just downright dangerous as a steering coupler. Al
