I had my 5100s installed last week and had the front set to .85, unfortunately I noticed the dreaded diff vibration right away on my way to have it aligned. I hoped that aligning would help, it did not. So now my truck is at a friend's shop (getting Thorley headers insalled) and I am having him take the level back to stock (man I hope it goes back to normal).
So my question is: Should I, must I have it aligned again? This has been a very expensive "small lift experiment".
Thanks for any help.
