Been considering a leaf check too. They're all intact and my mechanic says they're good but my nechanic isn't a spring specialist. Good and intact but does't mean they may not have tilted.
I was so hoping to see a video of a columbia drifting haha false title to thread hahaha one day I will grease my back tires and find a parking lot and do some drifting while bob tailing lol that would get hits on youtube. lol
Check springs by measuring from ground to frame from spring to frame. Check spring bushings check for bent rim try switching steers side to side maybe just what’s called tire pull. Common problem with steers . Usually just swapping sides if not break down tire and turn around on rim. Maybe shake is in driveline or loose wheel bearing or bent spindle Good start is where you bought steers have them flipped should be free if fixed problem. Check tires for out of round and ofcourse tr check balance Probably all it is needs balanced and flipped around to fix pull
Or a major miscalculation. In 25 years around the trucking industry I've never seen a truck put a quarter of a million miles on a set of steer tires
That’s pretty cool wonder how long rear ends last doing that! Reminds me of the time I spun like a top bobtailing on ice. It was much more exciting.
