Obviously you ain't got a clue what ya doing To remove the screw bar you don't need WD40 or any other rubbish you said just take up the slack on the wheel and it comes straight out with a couple of taps. Same thing for getting it back in take up the slack and it goes back super easy I'd be ashamed to post this video with how long it took to remove it when it should of taken 20 - 30 Seconds
