Iv got some Lonestar Racing A-arms on my quad. Maybe 20 hrs on them max. From the beginning, my upper arms had slop, like the bushings were too big for the pivot tube causing play in the upper a arms. I figure now that it is winter, I have time to get this issue fixed for good. I am waiting on new bushings from Lonestar, but I am doubting that this will fix my problem based on the fact that the bushings never fit right from the beginning, new bushings shouldn't fix the problem unless i was sent the wrong ones when I bought the arms. I am wondering if I should be using the stock dust caps to hold the upper bolt snug to prevent the play that I have. I feel like the slop would be fixed, but only because the load would be held by the dust cover holes and not the bushings. Im not sure if the covers are designed to hold a load in place. Any insight would be great or if someone is running these arms, if they can tell me if they are using the stock dust covers. I cant find the original installation instructions to verify if they are used or not. Thanks!
