Suspension
I'm looking into installing a 4" suspension lift on my 07 Jeep JK 4 door and I was curious to know if anyone who has done so already had to replace their existing drive shaft... While looking into lifts they all say the existing drive shaft may rub and need to be replaced with a drive shaft with a smaller diameter. Let me know if you had this problem or if that is just a precaution.
Also if you installed your lift on your own and if it is worth saving the installation money do it yourself.

Questions every newbie has
Q: Are new driveshafts needed after installing a lift?
A: You really should consider installing a new rear double cardin U-joint style drive shaft if you have lifted your Jeep JK Wrangler 3" or more and have a 2-door. This is needed because the short rear drive shaft of the 2-doors will be at a steep enough angle that the CV boots will wear out prematurely. However, in order to do this, you will need to buy a set of rear adjustable upper control arms so that you can properly set your pinion angle. 4-Door Unlimited models do not have this problem as their rear drive shafts are very long and a lift will not effect the angle of it too much. As far as the front goes, if you have an automatic transmission, you will need to replace the drive shaft with a double cardin U-joint style unit as well as the diameter of aftermarket shafts will be considerably narrower and will not come into contact with the transmission and/or skid plate. Failure to do this will result in the tearing of the factory drive shaft boot as it makes contact with the transmission. Manual transmissions will not have this problem and keeping the factory front drive shaft will not be a problem.
