Does anyone else have a "pop" in the rearend when taking off from a stop? It has been doing this since my purchase on 10-27-2015. When i put it it high or low or reverse and start to accelerate POP. I tried to overlook it or get use to it but honestly its very annoying. When im in rough bouncy terrain at slow speeds (you know when its difficult to maintain steady pressure on the accelerator) its pop, pop, pop. When im driving and let up off of the gas pedal to to brake or turn or whatever then get back on the gas POP. It feels like slack in the driveline. Its also very jerky or touchy in rough rocky terrain at slow speeds. Have any of you guys had or heard this noise on yours? Please let me know as im trying to find out if its normal or time to take it to the dealer. Thanks
