Idler arm support bracket shaft moves front to back like the bearing inside support bracket is bad. It is brand new . Literature said it was pre lubed and I pumped more grease into it. This movement allows a small amout of play and truck goes left or right constantly. New mevotech ball joints, tie rod ends, center link, pittman arm, idler arm, rotors, bearings, calipers. What is inside the support bracket ?

If it is new and has play, send it back and get another. It shouldn't have play at all unless it is all worn out.

Thank you

Did it have the zerk?
Should be solid.
