Wierd knocking under truck. Any Help/

Hey guys im new to the site and to powerstrokes bought me one about a week ago, got a 2004 F-250 SuperDuty. Got a question, I am feeling a wierd knock coming from under the truck, more when i hit a bump from any other time, i can feel it on the gas pedal and some on the floor pan. It is lifted, has anyone else had this problem? Please let me kno a solution if yall kno of one. Thanks!

you better not have a gas pedal !


knocks can be lots of things

loose shock / loose track bar/ and a lot of other things like tranny mount /cross members etc

best to climb under and start grabbing stuff

jack up the front and do the same

99% of the time on these trucks it's the sway bar bushings on the axle, or the end links. Or both. could be anything though like stated above.

good point on the sway bar

mine spits the top isolator out of the saddle every once in a while and it bangs around

my experience, if you can truly FEEL it, start at the track bar. sit idle, with truck running and watch it while some one turns the wheel side to side
