Tom - tried to pm you & your box was full. Tried to email you but it was rejected.

Ryan - since your vibration started after you lifted, I'm guessing that your best be will be to do the diff drop soon (you'll be wanting to do that anyway to save your CVs). Try shooting some grease in the U-Joints as well. If the vibration continues after that, move on to the next likely culprits.

BTW - have your wheels balanced - you may have thrown a weight. Sometimes it's the simplest of things that cause the biggest problems.
