will reevaluate toe later, but it looks good now.
Your car most likely has the one-piece jounce. They revised the rear axle during the 2006 model year. One of the TSBs I referenced summarizes the changes. It basically says to use the old parts until they are exhausted. Once all the old parts are used up then the entire rear axle needs to be replaced with the newer style if it ever needs to be serviced. The newer style has the two-piece jounce.
