Hello everyone,

I've been driving my 2015 G550 daily for about a month now. When I first picked up the car, I noticed a little squeak and clanking from the front end when going over bumps or cruising down the highway if the road wasn't perfectly smooth. I had my mechanic check it out, and he said there was no looseness or play in any of the front end components. The dealer replaced the right front shock before I took delivery because it was leaking, but the left one is still original. The noise seems to be getting louder, but I assumed it might be the left shock going bad or some bushings causing the noise.

However, today after grocery shopping, I started the car in the parking lot, and the dash displayed a "differential lock malfunction" warning. I turned off the car and restarted it, and the warning didn't come back. I drove for about 30 minutes in stop-and-go traffic without any issues. When I got home, I tried engaging the center diff lock, and it worked fine. I didn't test the front and rear diff locks.


I should add that I don't believe it's the hood squeak that others have mentioned, as every time it squeaks, there's a very slight feel in the steering wheel. The steering fluid is full, and there's no leaking from any components. However, whenever the squeak or clank happens, I can feel a very slight "unsmooth" sensation in the steering for a split second.


I'm wondering if anyone has had a similar experience. I can't seem to link the squeaking front end to the differential malfunction warning; they seem unrelated. My regular mechanic, who isn't a G wagon expert, said the front end is tight from his perspective.

Any input would be great. Thanks, everyone!

Mike
