Lower control arm pivot shaft 70 Challenger

[1 Wild R/T]

I will let you know when I torque it. I have to get a 5/8 NF tap for the nut to clean up the threads a little.

You don't really want to do that.... The nut is whats called a stover's nut.. It is an all steel locking nut, the last thread is slightly distorted.. I'm guessing your nut starts fine but the last thread seems to bind?  normal...

[Mopar5]

Wild R/T that is very good to know your exactly right starts fine and then really binds takes a lot of  strength to move the nut to the point I felt if I kept going I might strip some threads

[Mopar5]

Based on your advice I will nix the tap idea .The threads on the pivot shaft are good ,So I will go see if I can find a new Grade G or 8 Lock nut and see if that helps.

Slowly this dawned on me.The bushing actually moves very little in terms of twisting the outer portion of the control arm rotates around it independently for some reason I was stuck on the idea the whole bushing was twisting as the control arm went up and down

Pivot shafts torqued to 140 lbs no spinning in the sleeve

[Chryco Psycho]

did you have the weight on the wheels when you torqued them so the bushing is relaxed at normal height ?

[Mopar5]

I was just testing the ability of the pin to stay seated in the bushing . I am going to back everything off before I put it on the ground. Then final torque.

I figure I will probably have 50 -60 grand into this car by the time I'm done So I Just ordered new pivot shafts from pst just to see if the fit any better .On one hand-part  of me says it's probably good but I just want to make sure I do the best thing. If I have to start all over on the bushings now that's fine not going to skimp on 150 bucks

Following up here to everyone including myself who thinks pivot shafts diameter doesn't change it appears it can. I ordered the PST pivot shafts and they not only look better but pressed in with much more consistent pressure I am really happy with them as a plus they look better too.

Looking for some help here, I am installing the lower control arms and when I got to the passenger side  and put slight pressure on the nut just to snug it up the pivot shaft spun in the bushing sleeve. I noticed on this one when pressing the pivot shaft in it did not take much pressure.This is a brand new Moog bushing. So now I can push the pivot shaft in with only hand pressure but the fit is snug with no noticeable play. The pivot shaft appears to be clean with no damage. Can I install it like that ? Or do I need to to extract the bushing and start over? Any help would be greatly appreciated. Thanks Mike

What exactly did you mean in your first post ? That shaft looks like a rusted, pitted, piece of crap. I've never seen that area have any type of damage like yours does in that picture

Must be sitting in water. My old pivot shafts were in much better shape when I pulled it out. Did you order the greaseable shafts from PST?

I suspect someone used a center punch " a few times" in an effort to make it fit tighter.

Doesn't anyone read the entire thread? Even had a picture where he knurled it....

[Mopar5]

When I removed the originals the steel was in good shape without the slightest visible scoring or wear marks so I was puzzled why they were so loose and originally blamed it on the bushings Like John stated the picture of the old one was where I raised the metal a bit and the fit was much better but I decided to extract them although they may have been fine but why take the chance the PST Shafts are very well made  and an excellent price of 79.00 for the pair. I will definitely keep PST in mind for future suspension needs

Now that I've enlarged the picture and looked closer at it, I can see it a lot better....at first, to me it looked totally rust pitted  ....but now I see what you've done.....Certainly a strange situation
