Tow bar noise

[SnakeDoctor]

Back to OP's query, I have noticed that the WK2 is very noisy towing. I have 3 trailers and they are all noisy on the wk2. Race car trailer, 6x12 tandem & 8x5 single axle. Lots of rattling and clunking. Put the same on the rubicon- silent!

Dealership went down the path of tightening the bolt, already FT. Tried new tow ball too. No explanation apparent.

Dunno what the problem is. Possibly noise transmitting throughout the chassis?

Funny - I was searching for something else but yeah i've noticed that the Grand Cherokee really does transmit lots of towing "noise" into the cabin compared to my Wrangler and presumably other chassis/body cars.

That's so coincidental.
I have the exact same experience with my Grand & Rubicon.

Had my mechanic look right over the towbar set up and all is good.

Are your towballs the same size between the two vehicles?

Yep, balls are the same size

I know you didn't ask me, but mine are the same yeah, first thing I checked (calipers), it's much less noise when i'm using a McHitch/DO35 style setup where there isn't any slop at all in the connection but even a trailer I know that bounces and rattles all over the place sends very little noise into my Wranglers cabin but it's proper annoying in my Grand.

I reckon a little extra trailer noise is transmitted through the WK chassis compared to my old WJ for sure. The WK shares chassis technology with Merc ML, going back to the Chrysler-Daimler partnership and it is a much stiffer chassis than previous Grand Cherokees.

I reckon you will get a bit more noise in a monocoque, but in my case, most of the noise was the tow hitch rattling in the receiver. I simply packed it with either metal shims or even thick cable tie ends to stop it.
