i was finally able to install my new/used springs this weekend (thanks theferg for the springs) now i have got this vibration that comes on about 30mph and either goes away or is not as noticeable around 60mph. it only seems to do it when the drivetrain is in gear it will go away when i put it in neutral and coast. my thoughts are that when i lifed it the 2 or 3 inches it changed my driveline angle and my ujoint may be bad. have anyone else experinced this with a lift kit? can someone point me in the right direction? any thoughts would help thanks.
