front diff binding?

I have a 03 grand cherokee 4.7 H.O. with quadra drive anyway when in tight turns on drive pavement front wheels will hop and sounds like some binding going on. I recently changed both diffs with mopar 75w140 synthetic with additive and changed the t-case fluid with 247 mopar fluid. I have a limited powertrain warranty that will expire in a few thousand miles. I don't believe that this is normal and that it happened when it was brand new. Anybody have any ideas of what i should do?

Have the transfercase checked, The 249 were bad for binding when the vicious coupling failed, Not sure if the 247 have the same issues.
