Low air leaf bushings

There are some videos on you-tube that you can get an idea of what's involved.

 

Watching....... got the parts waiting on the time and confidense as well

 

Pretty sure my truck is just low air, and different from what you have, however same principles apply. Pretty much guaranteed to need the fire wrench to cut the nut or bolt head off one side. When doing this the rubber bushing will likely start on fire, don't put it out. Let it burn a bit and the rubber will start melting out, then you should be able to use a big punch and hammer to drive out the bolt and the rest of the rubber.

That's how I do it on mine. Fire is your friend. And sadly for being a peterbilt undies wearing kinds guy I don't know all the suspensions very well

 

I've got a 1999 Pete 379 with the low air leaf. Did the rear suspension bushings last year in the driveway. We didn't do anything special but remove the bolts (1 corner at a time), drove out the old sleeve & bushing, cleaned up the holes, put the new bushings in place, tapped in the sleeve, put the rest of the hardware on & tightened down. Nothing to it! Using a light coat of engine oil will help the sleeve go in easier.
