groaning sound in suspension

[JGordon]

My brand new Crosstour has a "groaning" sound originating
from the suspension system. My dealer ordered some "knuckles"
to install to correct the problem. Anyone else had this problem
and received this "fix"?

I have the same problem. The sound started at around 27000 miles. Dealer said is my tires. That the CT need alignment. I'm not so sure. But I do not want to buy new tires just to find out is something else.

My suspension groans, pops, cracks and squeeks all the time. OH!! but then your talking about the car.......

Could be the rear differntial, I had the same noise, thought is was the rear sway bar links. It was the rear dif, it needed a service, was covered under warranty

Yup, I had the same groaning sound. My Honda Dealer put my Crosstour on a rack, placed mini microphones all over the undercarriage. They pinpointed the groaning noise to my LR wheel bearing. They replaced the bearing, this took care of the groaning and increase my gas mileage 25 miles per tank.

Please tell me that they are not replacing a knuckle! It's just a piece of cast iron with a machined seat for a hub bearing and machined ball joint perches.

The issue seems to be a wheel bearing, although I can't be sure. To change a bearing, they need to free the knuckle from steering or suspension restrictions (ball joints, etc) and pull the brake caliper, brake bracket, rotor, drive shaft spline and move the knuckle to a press where the hub, old bearing and clip are pushed out and a new bearing, hub and clip are pressed into the knuckle. The knuckle is then re-installed, drive and brake components re-installed an then aligned. 90-120 minutes for each wheel and an alignment.
