6 all the inside has been redone carpet seats dash etc..

So finally im geting ready to drive this truck i notice the back axel is moving up and down when the truck starts moving does anyone have any idea y and how i can fix this. I dont have sway bar in the back or dont even know if that will or should i get a ladder bar insteed this truck will be used on the street and mud as well.

Any help would be great thank you

 

not a single person know what im talking about or just chose not to help

 

Are the u bolts tight

 

Yeah that would be my guess as well. Maybe the u bolts aren't tight enough or are too big for the axle.

 

Its not that, first of all, you posted this in the wrong section. This is an area to introduce yourself.
Second, if you would have read the forum rules you would have found out about the first one, and that you must wait 24 hours of getting no response to your thread before bumping it.
