I have a 2013 fx4 with about 85000 miles on it. I recently installed the Fox 2.0 suspension on it. Ever since I installed it I've noticed a slight vibration when coming to a stop or when I'm crawling forward at a freeway on-ramp waiting for the light. At first I thought maybe it was just the new shocks were transferring more road noise into the cab, but now I'm wondering if it's something else. It only happens at very low speeds 5mph and below. I'll be jacking it up and checking the front suspension out this weekend, but I'm hoping someone can maybe point me in the right direction. Thanks!

Had some time just now and there doesn't seem to be anything weird on the front end. Lifted the front spun the wheels with the motor on and off to rule out the 4wd actuator which is working just fine. Nothing is rubbing anything either...
My next assumption is going to be the rear U-Joints? Thoughts?

does it feel like a rumble? what are you running for tires?

Yeah, a rumble would better explain it. I have Toyo AT2's 295/70R18. They're pretty worn down and need new ones soon, but I rotate and balance every oil change.

probably your tires, rub your hand over the edges and feel if they are cupped or feathered.

That would make sense... My ball joints and struts were shot to hell.
I'll check the tires tomorrow. Thanks for the input.
