2006 V6 Grand Cherokee Laredo Rear Differential Noise
I bought my Jeep brand new from a dealership here in CT in February of this year... with less than 100 miles on. My work destination changed so I ended up putting on about 9k miles up until two weeks ago... at which time, I let my brother (a mechanic) take my 'baby' on a road trip to Florida and N. Carolina.
Well, my brother gets into Florida and calls me to say there's some rather noisey 'clunks' coming from under the car and that he's going to take it to the dealership to have them look at it (its got about 10,000 and change miles on it now). The dealership says it's the rear differential and that it needs work/replacement and that they will do it under warranty, but since the cars still drivable, my brother decides to bring it to the dealership when we get back instead.
Now, he's brought it back to TWO dealerships up here in CT and they says its "normal". I just drove the car last night, and it only made the noises for maybe 2 minutes total out of my 30+ minute driving. I tried it around town and also on the Highway and it only did it briefly around town.
The transmission/drivetrain/whatever (i'm not a mechanic) made NO NOISE when I bought it, and it definitely doesn't sound normal when the noises occur. To me, it sounds like a 'clicking'... almost like a CV joint that's gone bad, but it comes from the rear of the vehicle.
Should I press the issue with my dealership? It's been only about 5 mo. since I bought the G.C. and it's got 12,000miles. I would HOPE this type of noises won't become the standard on my baby.
Thoughts / Suggestions?
Any and all would be appreciated.
