I just went thru this myself, fighting for months. if you bought the Bulck Kit 6" A-arm. (which is a direct Chinese knock off of the American made All Sports A-Arm design), they chinese screwed it up. Because the drag arm isn't placed correctly, they needed to supply a "heim joint" that corrects the problem-( it replaces the ball joint in the drag arm with one with extended screw threads of about two inches) It's a problem that the All Sports superior design doesn't have. Problem is, I found out after hours of research, and by finally talking to great all around guy Dirty South who owns All Sports and the Buggies U. owner), is that the chinese neglected to box the part up that corrects the design flaw. Your easiest solution is to ask the seller for the part, and if its Buggies Unlimited, they'll supply it free of charge- but if you got it on the net, you may be screwed and have to buy it at Buggies UNlimited. I got mine from somebody calling themselves Gulf Coast Golf Carts and they REFUSED to supply it, even after an EBAY dispute.. I'll never buy there again. The part at Buggies Un is about $60 bucks--- "Heim Joint." My kit even included some doctored directions on which someone simply whited out the mention of the fix part. The seller swore up and down there was no problem with the kit and wouldn't budge. Only problem was, someone mistakenly included a second, correct set of directions (in my extremely battered box which I also had to chase down as it was shipped nearly two weeks after I bought and paid for it) on which I found, after the fact, that you could clearly see where the fix part was simply "whited out" by someone? Wonder who? Lesson learned, buy from All Sports or other reputable sellers who are responsible for their own designs. Now you know why yours, like mine, was cheaper. Good Luck Hittman
