i recently put a skyjacker ifs 4' lift on my truck, was just wondering if i should run stock ball joints or if there is a better ball joint that i should run? Also after i installed the lift i noticed a vibration while i was accelerating but then when i stopped or pushed in the clutch it went away. I talked to skyjacker and they said that i could use my original driveshaft. Would i need to rebalance my shaft or is it possible that my pinion angle is off? I KNOW IFS SUCKS but the lift i paid 600 for with new leafsprings.
