Moog leaf spring bushing, '90 F350

[irhunter]

I bought Moog SB349 bushings for the front leaf springs. I was thinking they'd take 9/16" bolts (.567"). But the ID of the bushings is .581" which means I'd have .0185" of slop between the bushing and the new bolt. That seems like too much.

The OEM bushings were about ID = .552" and the bolt was about .543" for .009" of slop.

Anyone use these bushings? What bolt did you use?

The tightening action of the bolt on the edges of the bushing is what holds it.

Interesting.

I tell you what, however, that 9/16" bolt in the new bushing just "feels" way loose.

Don't snug it. Tighten UP!!
Been there. Grease up the inside of the shackle tube.

Right. Ford calls for 120 to 150 ft #.
