Sway Bar Linkage help

Hey yall, now I haven't really navigated thru this entire forum yet, so idk if this is a question that has already been answered. I have an issue I'm looking at getting some input on a possible resolve. When driving my jeep at 60mph or less it handles great (for a lifted jeep anyway) but once I hit anything over, especially 70mph, it feels like I'm fighting 80mph wind the whole time. It just wanders in the lane like crazy. The wheel itself is tight and really touchy, but one small movement and it wants to shoot across the lane. My next door neighbor actually has a lifted jeep and told me to check the sway bar linkage as a big possibility. So I did, here's where I need input: It seems like when the lift was put on, they put the frame spacer in perfect, but now the sway bar linkage is no longer straight up and down but at an angle and putting stress on the bolt. Could this be the issue?
