Yes sir it's a shitty job. Hopefully neither of us will ever have to do it again
It makes a huge difference to how the car feels though hey?
I did the ones at the front of the rear diff at the same time. It feels alot better now, my old ones weren't as bad as that though. You would of had a good thump?
As you said is how I was always told what it does. It just feels so smooth when giving it some. All I know is one good thing I did, even though it was the biggest pain in the arse on jack stands.
