2 questions (1) weird vibration around 30mph (2) front leaf question
 

ok to start off for (1) when i am driving and accelerate to about 30mph, the entire truck starts to rattle and vibrate and stops after 35mph. i was thinking the universal is shot from it happening to a friend of mine but its the universal from the tail shaft on the transfer case. any ideas?
(2) i heard if i flip my front springs over (all except for main leaf) that it will lift my front end 2 inches due to the opposite arch. is this true?

About the shake at 30. Make sure your tires are balanced. It happened to me lost a few weights on the trail, shook like crazy after that

the tires have never been balanced but havent given me that shake but i found out it is most likely the ujoint and will let you know saturday if it was because im doing a new one

Hahaha Funny there not arched backwards they are sagging backwards if you lift the truck on the frame with the diff removed they would arc back the proper way. You either need new springs (Best option), custom front airbag kit( My personal favorite), add a leaf or re-arc the current leafs but that doesn't last more then a couple years.

You can buy a set of 3 inch gas springs they have one less leaf than diesel and they will settle at 2 inch. I put a set from rancho on mine 17 years ago and have had no problems running 33x14.50 swampers
