I drove across an uneven grassy area to get to the softball field at my church Thursday and heard a loud pop. Noise got louder and more frequent before I got back to the parking lot. A quick look underneath confirmed my first thought - sway bar endlink broke. Ordered MOOG Problem Solvers online from Advance Auto. Reg price is $21.39 each. By ordering online and using the discount code and a Speed Perks reward I had, I got them both for $32.03, tax included. Putting them on this morning, I found the broken one had been broken for some time, but didn't make it known until Thursday. On the driver's side, I had to jack the end of the sway bar up to get the puck on top of the sleeve in place. On the passenger's side, I had the opposite problem, and had to pry the sway bar down just to get the nut on. And when I tried to tighten the nut, the bottom (and I assume the top) puck was bulging, but the middle ones weren't even seated and I could turn the sleeve by hand. I drove about 2 miles hoping things would settle. It helped a little, and I eventually got it tightened.
