Rear sway bar bushings - just get the actual Ford part.
I have a 99 Explorer, my suspension was so bad I felt like a bobble-head while driving.
Finally got warm enough, I had a chance to replace my shocks/sway bars. I'm going to start a thread about the whole process, but I wanted to post on this thread. I tried to replace the rear sway bar bushings with aftermarket parts from Energy - part # 9.5106G which is the non-greaseable universal 19 mm bushing.
THIS PART DOES NOT FIT!!!!!!!
The bolt holes do NOT line up with the bolts for the rear sway bar.
I ended up talking to the guys at the local Ford dealership, they ordered me a pair of genuine ford rear sway bar bushings.
Part # F57Z-5493-BD they only cost me $15 for the pair.
I was afraid that these were going to be hard to install, because they don't have a break in them, its a solid bushing. It actually was not that bad. I added a bit of extra lube to the bar, just pushed/twisted the bushing into position. Took me less than a minute to get each one into position
