Anyone know for sure the correct sway bar bushing, like a Moog or Energy Suspension part number?? Here's why I ask...I measured the sway bar at the bushing and it's right about 29mm. Seems simple enough, right? Well, you can look at the bushing and tell it's the one that sorta triangle shaped. There are bushing available in 25, 27, 29, 30 mm, and a few others. BUT, the pictures of the 29mm in both Moog and Energy do not look like the correct one. Odd.

And when you read the parts description for all these, it says the 29mm is for a RWD drive truck. It list 27mm for 4WD. I have a 4WD with a 29mm bar.

Any thoughts?

 

Front to frame bushing: Triangle shaped.
Ford # F75Z5484 FA.
MEVOTECH MK 80074.
So say ROCK AUTO.

 

I believe all the supercrew had 29. That sticks in my head for some reason

 

RockAuto and everyone else calls for a 27mm for 4WD. I measured the bar, it's 29mm. BUT, the 29mm bushing is not the triangle shapes is on the truck. So, I got the 27 and put it on. It did look a tiny bit too small (about 2mm, LOL) and the two ends didn't touch once wrapped around the bar. But, it was minimal and they went on and the bracket went back on just fine. Is it possible to clamp down on the bar too much? What's the worse than could happen? It drives completely great, so I'll watch it for a while.
