Zeus, allow me to introduce myself, my mechanical experience is very limited except for oil and brake changes and I tend to keep my vehicles as stock as possible except for small performance improvements
now, with that said, my VX is about as stock as you can get, the only thing I've done is replace the speakers, replace the brakes/rotors and brown-beaded the cargo hold
I will most definitely NOT be fiddling with doing differential work myself, we want to keep VX's on the road not on a flatbed en route to the dealer, haha
I understand based on my prior comment how you might have thought I was going to do it myself and I appreciate the head's up on other work to be done at the same time, but no, this is definitely something a professional will look at
