Question about 2009 Jeep Grand Cherokee
A whining/humming noise is heard when foot is removed fromt the gas. The sound is more audible at 65 mph decelerating to about 40 mph. The sound is audible at lower velocity around 20-40 mph, but has a less noticable tone. I took it to the dealer and they ran tests and concluded that nothing was wrong and that it may be a computer programing glitch with the gear ratios when downshifting automatically. I have a liftetime powertrain warranty. What should I do?
I would tell the dealer you want your rear differential opened up, checked, and more fluid added. There really is no test they can do other than to pop the cover off the differential.
