I was hoping this would get rid of that annoying squeak and rumble in the suspension but that wasn't the problem. Replaced along with the stock anti-roll bar. See Addco 684 1" Sway Bar. I don't know if this will extend the life of the suspension, but it's a cost effective option and will last much longer than rubber mounts. Over 10,000km/year the right hand hub is worn out of the circle despite regular lubrication .
