Drives way better! No more darting to the right then left as I hit the brakes! I got so used to it, I almost didn't notice anymore, but I sure do now. Night and day!Well, I'm stupid...not that everyone hadn't aready figuered that out based on this thread! I went to HF to buy a hydrolic portable press thing today to push the pins out on the shackles, but they were out of stock, so I went out to give it hell by hand at lunch with the torch and hammer! Turns out the shackles are not stock but are a 2 piece unit with both pins welded to one side and then a removable plate on the other. All I had to do was take off both nuts (which I didn't do yesterday) and hit it with a hammer a few times. lol! Took me 30 minutes to do both sides and I didn't even have to take the wheels/tires off. hah! Anyway, the bushings in the spring were a little crusty but the top ones were pretty decent. They likely were replaceded back in 2012 when the current overhaul took place. I sort of doubt this is the source of my noise. Either way, it has been a little shifty when I hit the brakes, so I'm guessing this should help that a little and if not, at least it's piece of mind and one less thing to worry about! Bonus is I already ordered a set of greasable shackles so I know how to put those in real quick now!
