I'm in the process of rebuilding my front suspension and I think I'm having a problem with the LCA pivot pin. When I try to tighten the pp nut the pp spins. Is this ok? Shouldn't  the pin be held tight enough by the bushing in order to tighten the nut?

[anlauto]

Yes I agree you have a problem if the pin is turning inside the bushing.

I guess those Delrin bushings I'm using are junk huh?

Most likely this one is junk, but you're probably best to remove and replace.

Is it happening on both sides?

[61K T/A]

I mocked up everything last night only on 1 side. I'm doing the other side  tonight.

[Bullitt-]

I tightened the nut prior to installing the bushing if I recall correctly...
Did I do it wrong?   

[fc7cuda]

Hmm, there are several different tricks for installing the bushing. Generally tightening the nut is the last thing.  After the car is on the ground and the height is set, then final nut tightening. 

I usually press the bushing into the LCA first.  Then I screw the nut on the pin far enough to be flush with the top on the threads to create a nice flat surface.  Press it in the bushing.

Do you have the factory service manual?  It has pics along with detailed instructions that would be useful.  Some of the "special tools" in the book are avaialbe, but you can instal without if creative.

Thats the way I did mine. The pin was very tight when pressed in. Bushings from Y1, yes I know they bring them in from other sources, Just a FYI

The bushing and pin are already pressed in the lca. It's when I mount the pp to the K frame and try to tighten the nut the pp spins in the bushing.

[RUNCHARGER]

Hmm: No it shouldn't spin. I don't think it's a terrible thing though, just hit it with an impact after your ride height is set. Are the torsion bars in, set to ride height and sitting on it's wheels?

[Brads70]

If your using anything other than stock rubber bushings that can happen. I'm using urethane and it happened to mine also. I drilled and tapped for a 1/4 or 5/16 bolt so I would have something to hang onto to prevent it from spinning. When it was tight I simply removed the bolt and installed the torsion bars.

It depends on what kind of bushing you are using.  If you are using a stock rubber bushing, you need to tighten the nut AFTER the car is on it's wheels and AFTER the ride height is set.  The rubber is bonded to the inner/outer metal sleeves.  The bushing needs to be in a neutral position when the car is at rest/at ride height.

If you are using a poly bushing, the pin is just free to spin inside the bushing.  The bushing material isn't bonded to an inner/outer metal sleeve.  I've heard of people installing the pin into the K-member and THEN installing the LCA on the pin.

What you are describing is completely normal if you aren't using a stock rubber bushing.

I'm using rubber Moog bushing to completely rebuild my front and rear suspension. Do you need to lube any of the bushings prior to installation? Any other hints/tricks when rebuilding the suspension? 

[Rev-It-Up]

Looking forward to the responses!  We're getting the front suspension parts lined up now for the duster.

Pretty sure polyurethane bushings need to be greased before installing them to keep it from squeaking.  I don't use them, but people love them and they get good reviews.

If you lube the factory rubber ones make sure it's with a rubber safe and not a petroleum based grease.  I think the stock rubber ones can run dry and be okay.  But not 100% sure
