what do i have to adjust to fix this problem?

[blueb8llz]

ok after adjusting the links again. its pretty straight now. gosh i had to bring that wrench out there with me and do very minimal adjustments to make it go straight.
but the thing with the reverse going to the right is still a problem. i noticed the rod end on one rear tire is loose. what i mean by loose is hollow ball that goes in the rod end, its has alot of play. so much where i even see a gap/opening between the rodend and hollow ball. so im guessing this might be the problem with my reverse. when i grab my tire and wiggle it, it has alot of play where as the other rear tire barely moves.
DOES ANYONE HAVE TWO SPARE ONES THEY WANNA SELL ME, ALL I NEED IS THE ROD ENDS. BUT IF YOU HAVE THE HOLLOW BALLS THATLL BE GREAT TOO. PM ME WITH PRICE. heres the link if you dont know what im talking about.
