I think this might be the source of my problems, well at least the clanking during accelerating, vibrations at high speed, etc...

How do I fix this? This is on the passenger side, front spring, rear mount.

i cant see a pic if you posted it. ive broken the exact one off except mine was completely shattered. i welded a new one back on

[Crazy_Jeepman]

I have broken quite a few of them. Knock the rivets out and put bolts in.

[youngjeeper]

ok i see now, yea just put bolts in or weld it on. those lift springs put stress on the spring mounts

[gwinn]

Yup done it twice! (different springs) I took off the springs, cleaned up the joints with a grinder, lowered the bracket onto a jack stand so it compressed tight against the frame and welded it down. Did your front shackle fold forward and lock in anytime before this happened?

Looks like it was repaired once before. :cool:

Gwinn, How did you know!?!? That just happened a few weeks ago... I was quail hunting in bulldog canyon and my shackle got stuck folded in the forward position during some articulation. I didn't realize anything broke though... What happened?

This must also mean my clanking and vibration is caused by something else...that sucks!

[JeepsAndGuns]

The top pic. That looks like a broken weld.

[SJ]

I guess I need to inspect the otherside better but I thought they were welded on the inner side from the factory. But that aside, some have suggested using bolts in place of the the rivets. How is this done, the frame is closed at that spot. Also, would a weld be a better and longer lasting fix?

[Poley]

welder' up!!!

yep.. this is common to alot of folks here.. I found mine cracked and then RBY's was really bad...

mine was just a reweld under full weight on the stand...

RBY's was a little harder... had to remove it and patch the brittle frame under it, then orient it back into position and fully weld her up...

My pass side hanger broke clean across the full inside bend. I welded it back together across the bend but not the frame since I knew I would be replacing it. When I did replace it I noticed the replacement hanger was not parallel to the front hanger/shackle by 3 degrees. That’s why I think the original broke clean across the full inside bend of the hanger. Eyeballing the hanger to the axis of the rear axle housing confirmed that the hanger needed to be shimmed in order to hang straight and parallel or else more load would be applied to one side of the hanger. Removing the hanger was very easy by torching the broken side off where I welded in order to get access to the rivets with a grinder.

Hanger was broken clear across the inside bend.

When I removed the springs from the driver’s side hanger I found that it also was not parallel and that’s when I realized that my frame had been slightly over-formed during manufacturing resulting in anything mounted from the side or bottom would not be parallel with the rest of the truck. All these years the load was not distributed evenly across the hangers. I had to hammer the bolts and springs out of the hangers because they were in such a bind. I C-clamped the replacement hangers in place and attempted to run a ˝” steel rod through all four 9/16” spring holes, but the alignment was so far off the steel rod missed by 2” vertically from one side to the other. I also noticed that because the hangers were angled inward to each other the center distance was 31 ˝”, not 32”. After shimming both replacement hangers with steel shims making them parallel to the axis of the rear axle housing I ran the ˝” rod through all four holes with ease. Then eyeballing the rod clear across the frame to the rear axle housing I found that it was nice and parallel. The center distance was back to 32”, too. When I installed the springs back on the hangers and shackles I found the springs slipped into the hangers and shackles very easily and I could install all the bolts with two fingers. I am sure this will allow the spring bushings to flex easier since they’re not bound up to begin with. :cool:

Original hanger out of parallel.

What would you all think about drilling through the top of the frame and using long bolts to fasten the mount to the frame? It seems to me that you would have to open up the frame if you used normal length bolts.

I have no welding skills, not to mention no welder...

I am really thinking I will have to take it to a shop to get it fixed.

ripped both mine out, found out what was making most/all the sqeaking nioses...

made a drawing, took to machine shop and had them make these

STILL need to have them welded on but bolted up still holds ok for now

http://www.fullsizejeeps.com/jeeps/files/Misc-Pictures/shackles.jpgThose look really nice, but i must say, they aren't shackles, they are spring mounts ;)

[SJ]

Phil, those look great! You wouldn't still happen to have those drawings around, would ya??
Do they hold the springs in the exact same position as before?

[JeepsAndGuns]

Wow, those are bling! I know what to do if mine ever break off.

[flatbackdragon]

yeah yeah mounts not shackles, what can i say.....i'm old, i broke em, ok? geez...

SJ---may still have the drawings will look, they drop the eyelet just about 1" lower than what it was, i spose

mine din't exactly 'break' off, they RIPPED out of frame, old MOUNT was still usable just wanted something bigger, should have welded the frame back together before putting these on too, still could, just take bolts out and remove mounts, some day maybe

[Merc69]

Phil...please share your drawings :D

Thanks

[River Beast]

VERY NICE WORK!!! Those are definitely AWESOME!!!

[Tad]

Oh My, those are very nice.
Our body mounts & that bracket move around a bit thru the years and styles but that's a trivial problem.

[flatbackdragon]

merc69--your drawings

all 1/4" steel
pretty simple, cutout on outer plate and angled in rear to slip between body mount bracket on outside, slipped right in, bolted it and put spring in, no problems

[Merc69]

Thnaks Phil. I'll be adding it to my list of things just in case. They look great.

Thanks

[scotty]

hmmmm,mine are still atached to the frame,guess maybe i better but out the welder before that changes :D
