How did this go for you Chris? Did you end up having the subframe replaced and was It a big job?
I recently came across the same issue with my lexus rx300, 2004 rear subframe corrosion, so will just have it replaced but also looking to get a full Dextron underseal and cavity seal carried out, I know technically the corrosion has started but if done right should slow it down considerably, I want another five years out of mine if possible as its a lovely car otherwise and plan to run it until it dies.
