O.k. so the jeep just got a reman engine,because the old one had so much blow by my driveway is now a moat (still ran fine though)Anyway with a new motor time to take care of all the annoying noises. alls well until around 60 if I let off the gas noise goes away. Already replaced both u-joints in the rear drive shaft and am about to do the front.My thought was that it may be the crappy pepboys 31's(bought w/american racing rims in want ad $150)but they were on before noise..maybe there out of balance.Also I didnt want to balance them because next week 3.5"susp and 33's .I need to fix this problem before the lift as not to mask it further any help would be appreciated
