clunking noise in rear- differential?

i have noticed the last couple of days, when i am stopped and accelerate from a stop, there is a clunking noise coming from the rear wheels of my car...im pretty sure its not motor mounts, and have a feeling that its my differential slowly going...what are some symptoms of problems to look out for?
could it be something else?

FAR888 had a similar problem with his left rear wheel and it turned out to be the RIGHT side motor mount./ Maybe this could also be your problem. You should have them all checked out.

You might also want to look at the torsion bars, as they have plastic inserts between the metal, which do crack.

That's correct ml3addict - I could have sworn it was coming from the rear wheels and it turned out to be my motor mounts - Have them checked out.

Best of luck!

Do you have some proof to back this up? Not trying to be a dick but, clarify please. Just give something more than what you think - what causes you to think this? Don't get me wrong...you could be right - even a blind squirrel trips over a nut in the woods sometimes.

BTW, welcome to the forum!

I'm thinking these guys are right OP...check the mounts and torsion bars. WORST case scenario...ckohli is right...diff could be going (lets hope not).

I am interested in this discussion also. My 98 ML320 with 190,000+ miles just started doing the same thing. There are no codes and it only happens when I accelerate hard from a dead stop. It sounds like the rear differential is slipping. It is pretty loud and something I want to get addressed. Sounds like a job for an indy? Thanks.

Keep in mind a loud rattling could be the cat heat sheild...also, if your ball joints are bad...another thing it could be. Just my .02

Have someone rev the engine while in park, and see if the engine moves to one side or the other. If the mount is bad, the engine will move quite a bit when you rev. I had the same problem, a thunk when I accelerated from a standstill. It felt like someone was kicking the seat. I think the right (driver side) mount is the one that goes first in a lot of ML's.

Hi guys, this link might be useful for you

My ML had a similar noise, i thought it was the rear axle, but it was the transfer case.

Good Luck

It's certainly the one that 'went' first in mine!
