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?
Yes I agree you have a problem if the pin is turning inside the bushing. :alan2cents:
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?
I mocked up everything last night only on 1 side. I'm doing the other side tonight.
I tightened the nut prior to installing the bushing if I recall correctly...
Did I do it wrong? :notsure:
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. :alan2cents:

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.
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?
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? :thankyou:
Looking forward to the responses! We're getting the front suspension parts lined up now for the duster. :popcorn:
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 :notsure:

I always use spray silicone on all my rubber items. It's rubber friendly. Just make sure to install your part quickly because the rubber soaks it up fast!!!

Right now I just want to snug up the pp so I can install the rest of the suspension and brakes. A 1/2 impact gun is too large to get to the nut. So I'll be using a 3/8 drive air ratchet to get in there. Once shes on all 4's I'll make the final adjustments.

If the air doesn't work I'll be taking this route.
1/2 inch drive air gun with universal and extension and the nut went right on, BAM. 3/8 didn't have the umph. Thanks for all the help. Now I can sleep tonight.
I'm in a similar situation right now... Firm Feel's Delrin bushings (white colored)... LCA can't be brought all the way in yet as the PP spins... and I've also installed the TBs.. will try again.. car is up in the air (no engine for a while.... next year.
Use grease when using polyurethane bushings. Like Burdar said it's a completely different set up. There is nothing to grease on OE type bushings other than using something to make them press easier. There is a trick I like to use when pressing bushings in-cased with steel sleeves. I put the new bushings and pins in the deep freeze for a couple days. That will make them shrink just a tiny amount. That will make them press in a lot easier. Then once the bushings warm up pull out the pins and press them in. This trick works great for pressing anything metal. Wheel studs, Pilot bushings and bearing races.
Critical Warning
Like people have said before. When using OE type rubber bushings you never want to tighten the pins until the proper ride height is set and car is sitting on the ground. If you tighten them up before that and then set the vehicle down. It will twist and tear the rubber bushings. You might not notice it at first but it won't be long before you start hearing squeaks and noises coming from them. Then you get to do it all over again!
I learned that freezing trick when I worked on heavy equipment. Made beating in new pins and bushing a lot easier. :rebelflag"

:iagree: I used Firm Feel's grease-able pins. I put them on the lathe and turned a grease groove so the grease goes all the way around the hole.
That groove is a damn good idea. I have the Hotchkis ones like that. Building a set LOCA's for my Cuda just like those. I think I will do that to them also. It kind of blows my mind that you did gold color. I was planning on painting mine gold as well to match the other Hotchkis stuff. Thanks for sharing! :ohyeah:
I got a nice clean pair of lowers( These are A-Body LCA's that I use with C-Body spindles) cheap that no one wanted because they didn't have sway bar tabs. Easy to make your own, stronger than stock too! ;)
I thought those tabs looked awful nice. Great work! :clapping:

Brad... could you please explain that a little better? T/Anks ahead.

Sure, on the LCA pin the big end that ends up in the bushing I drilled and tapped it for 1/4" . I then installed a short 1/4" bolt so I could use a socket to hold it from spinning while I tightened the other end in the k-frame. When it's tight on the k-frame simply unscrew the 1/4" bolt and discard, then install the torsion bar. There is enough room even when the pin is installed in the LCA.
Hope that helps? Worked for me anyhow?

Wow, glad I saw this, I need to loosen mine up before I put the engine/K-member assembly up into the car!
Thanks!
