On my mojave I have noticed that the front right suspension keeps making a loud knocking noise on the rebound. Like if I go over a log it knocks when the wheel is going back down. Any ideas of what this could be or how to fix it? Also the front shock lower mount is wallowed out and looks like an oval. I tightened the mounting bolt down so I can ride up and down the gravel road but am afraid it will cause more damage. When I re-weld this, how key is it to get the hole exactly where the old one was at? Thanks in advance...
