Hello. I'm new here, first post and all.
So I'm driving a 2003 King Ranch 5.4L w/6" lift on 35's all wheel drive and 4 wheel drive.

Last night I noticed my ride has changed. It feels like I'm going over little speed bumps or hitting shallow pot holes. I noticed it all speeds. I don't feel it in the steering wheel, but the pedal and in the ride. I also noticed my trucm seems to accelerate kind of slowly now.
I'm not a "car guy". Just trying to figure it out or see if I need to take it in. I appreciate any help I can get.


P.S. I noticed this wasn't attached on my rear axle.
