put some grease on both sides, and once you get the bushings started, tap the arm all the way in past where it’s suppose to go from where the ball joint goes with a rubber mallet. Then use a small pry bar on the top and bottom and work it back towards you. Depending what pan you have, the technique of inserting the bolt will be different. I have the rear frame stiffener brace and I got rid of the stock bolts and replaced the with tapered allen heads. Once you get the holes lined up, stick a long Allen wrench in and twist it in as you lightly tap with a mallet. Goes right in.
