not to cast aspersions, but it's also the case that not everyone who goes on a guided off-road trip is a wrencher. some people have money and they believe what they're told about stuff they don't have expertise in.I considered the comment on the 2 replacements, too. But like @trinydex mentioned, the author is clearly an ARB believer, so he could be lying or fed bad info from the Harrop rig owner. It could even be the installer is totally inept and keeps screwing up the installs.
all these are just data points. I'm just trying to get the best picture I can get before I spend my money.
