Chevy TrailBlazer Front Differential Problem
I have an 03 TB, LT, with 413,000 km (256,600 miles) on it. 3 days ago heard a bang from underneath, then a loud clanging sound from the front. No vibration or driveability issues, took to dealer, couldn't diagnose, drove home, sound diminished. Took to dealer, reprog the front diff actuator. Works fine in all settings: 2WD, A4WD, 4HI, but is noisy (grinding?) in A4wd or 4HI, but quiet in 2WD. I am suspecting the front diff is gone.
Any insights?

I ask because our TB has a strange resonance in the interior when someone opens one of the windows on the rear passengers door when both of the front windows are closed. It makes the kind of noise you describe.
It's done it since new (2002) and since we rarely open the windows I don't think of it much.
Gear noise rear diff.: common and nothing really reparable or adjustable. Did not ask about heavier gear lube to quiet it down.
"Turn up the radio" is the last laugh so...............................T or whole new rear pumpkin! And it may still reoccur.
Another thread follows.
Thanks for allowing my posts.
