Weird Sound when Accelerating

[floriandotti]

Hello all,

I have recently noticed a weird clicking or almost grinding sound when I accelerate. It's only at low RPMs, but if I accelerate quickly, I think I can almost feel something being torqued behind me. The sound comes almost from the boot of the car, but I'm not sure if it's IN or BELOW the car.

Then, when I brake quickly, it sounds like something is lose and gets rattled forward, but I can't find anything loose. There's nothing that could be making this sound IN my trunk, so I have no idea.

Any ideas?

Is your car equipped with drum brakes in the rear?

Could be driveshaft related, either U-joints or center support bearing or guibo.

axles, or wheel bearings
