I’d have to agree… being that the vehicle is RWD and everything in the rear end has been replaced and is now brand new, the handling of the vehicle will greatly improve since theirs no room for “play” in any of the hardware.
Since the wheel bearings are also brand new you might even notice a tiny increase in fuel milage as the bearings will spin easier/quicker so the car should roll easier/smoother.
Glad to hear that you are pleased with the outcome/finish thou Nick and I was shocked to see that you’ve already got it back together and everything pressed in since you only picked it up thursday, you must have been pretty busy
