I replaced the passenger side guide rod mount on mine. You state that you've replaced both "guide rod assemblies" I would think you've replaced the guide rod mount?

At any rate - the mount is no doubt collapsed from the impact of the tires on the curb. If you didn't replace the mounts, you should. It was quite obvious the one I replaced was no longer functioning once I had it out of the vehicle and compared to the new one.

Not much fun to replace. You must know that from the guide rod work you've already done.
