    I must be hard on ORD shackle bushings.
    After the first greasable set failed, I tried the new, harder compound bushing set. They lasted longer than the originals but I have somehow ripped and mangled those as well.

    Do you guys have anything other than the HD black bushings to try?
    Should I call and just order a new HD black set?

    Thanks,
    todd

    What are you torqueing the bolts too? Should only be 45 ft lbs.

    A buddy of mine has cracked his before, I think its because the bigger bolt doesn't leave enough material for the bushing to withstand given forces.

    Just a thought, might be totally wrong :o

    Are you running a hardpan bar? You might need one.

    im not really sure what a hardpan bar is, maybe a sway bar, but i have gone through several sets of the bushings myself, im on my 4th set, but i have noticed that when i do more street driving, they seem to last longer, so maybe it is a lack of bushing area and maybe have something to do with how much flex the trucks have, i dunno....

    I have always had prob's in the past with front end bushings untill I started running a panhard bar. A sway bar will not do as effectively as such.
    The panhard should connect to one side of the frame and drop across to the opposing side of the same axle. You may need to fabricate the set up. I do belive ORD supplies these bar's. Make sure you keep a line as level as possible across the front end for flex up and down. I used a panhard from the rear of a TJ Jeep. I can send you a pic if you want to your personal e-mail, I cant post pics here.

    Aren't the shackles supposed to be able to move within the frame?? Or am I more than 1/2 a bubble off??

    If so are bolts too tight on frame?? :dunno:

    There's just not much space to work in with either factory eye. I have some ideas on how to improve the bushings a little but we're still dealing with a small hole that has a big job to do. I hate to say this but at this point, they're a replacement item from time to time.
    The bolt and sleeve size are set to leave as much bushing as possible while leaving some strength in both. In fact, we went to a 4130 chromoly for the tube to help keep them from crushing and to get some more consistent material in that area. The real answer is new bushing mounts for the top and new main eyes on the leaf spring along with a longer shackle to make it all fit under the frame rail but that's a lot of modifying.
    It is a matter of twist, under more "normal" conditions, the bushings will last for years, some hard trail riding with lots of twisting on the front springs and they'll split.

    Anyone tried rubber bushings? The springs that twist hardest on my truck are the 57" rears, and the factory rubber bushings are holding up better than any poly bushings I've had...

    :dunno: :dunno: :dunno:

    Hmmm.

    I know the OEM and Aftermarket springs are gonna use diff size spring eye bushings.
    Anyone have a part # or application for rubber bushings that will work in aftermarket springs using 1/2" bolts?

    Hell, at this point, I'll give them a try if I can find them!

    The problem with rubber is the rotation, it can't rotate without tearing since all the parts are bonded together.
