Question About Shackle Mount Area Frame Repair
Ok - so my frame is swiss cheese right around the rear shackle mount on the passenger side. Totally normal for these Jeeps as I understand. I also understand that this is not a frame repair for the novice welder and I CERTAINLY fit that category. Hence I took it to a reputable local welding shop and was quoted a price of $200 to fix it. DONE!

Except, I stopped in today to see what was up. Dudes told me that it took them 4 hours to drop my gas tank. Still trying to understand why but I was wondering at that point if my Jeep is in the right hands.

Sooo while I was there they pointed out that there is a rubber bushing involved in the shackle mount. My 3-part question is as follows:

1. What is it/how does it work?
2. Do I need it?
3. Where do I get a new one if I need to replace it?

Any help would be a huge contribution to a heck of a heep.

wow 4 hours to drop a tank....

go ta about page 3 maybe 4, gas tank drop is hour MAX, if all the bolts are rusted, took me 45 minutes, did it on a lunch hour, never even changed my work cloths... broke one bolt and impacted the rest off, 2 guys and done....

4 hours blowing smoke up your ***.....

wow the rubber bushing is your srpings bushing I would think, do thises guys know anythng....

any spring shop can get ya new ones, I removed mine and reused them when I repaired myshackle area....

$200 is a pretty good price, but when I did mine i didn't have to drop my gas tank and the replacement frame piece had new shackle bushings in it. They are just shackle bushing and you can get them almost anywhere for like $6 max.

Can anyone let me know how they install? Do they just slide over the extended end of the shank tube for the bolt that goes thru the frame? Dudes were trying to tell me that they go all the way thru the frame...not so sure about that.

the bushings are two parts, one on each side.

here's two sets

hallsofstone 07-22-2010 03:29 PM

Crap I'm retarded, I think those parts actually came WITH my lift kit. Chalk one up to the idiocy of a Jeep noob.

hallsofstone 07-22-2010 03:31 PM

So those brushings actually fit into an oversized tube that goes thru the frame, right? The dude was trying to weld a small shank tube thru the frame to fit the shackle bolt, but that did not look right to me. I knew something was wrong!

agreed on that being a good price. I think the replacements are more than that on quadratech.

Was the frame so far gone that they were not able to see how it was or are they just morons? I would be concerned about them getting the placement right too.

Here is a ready made part to weld in

Just called the dude and stopped him from welding a solid shank. Now that he looks at it he sees what we're talking about. Anyone know what size those bushings are? Maybe measure the diameter of the part that slides into the frame...

They should be smaller than the ones that go thru the eye on the leaf spring, right. Got a box of those that came with my lift (which is NOT in the orginal packaging/lacking instructions or item list, though was sold to me as "complete except for the U bolts").

hallsofstone 07-22-2010 08:26 PM

I ran home on my break and grabbed what I think is the right brushing/shank tube for that bolt size. Tried to sort of guesstimate if that would be it judging by the size of the one on my Dad's 94 which I've stolen for the time being. Seems to be the right part.

Pics of this mess to come. Thanks to all for your help!

OK - so the frame is fixed. Still working on hauling the pictures of the previous swiss chease status, but I do have a couple of the fix from my cell. Will post those back when I get off break.

The guys at the shop said that they took a loss on this project because of how much time it took to take the gas tank off and put it back on (as well as the engineering mishap with "how to do it right"). I even offered the shop manual for the Jeep to em, so their loss. They also left the original bushings on there even though I left them the brand new one in their mailbox. No idea why that was. I paid the $200 and left it at that.

Pics to come real soon.

giggityjeeper 07-26-2010 06:59 PM

their problem I wold think 4 hours to remove a gas tank, mine has not be removed in 21 years and I got it out in 45 mins.....

and Im far from a mechanic..

they left the bushing ause they did not want to burn them out, prollythey wre not coming out, only wayto get them out then is burn them, more time consumng....

hallsofstone 07-26-2010 07:53 PM

Here's one good pic:

What do you think. Kinda sloppy work but it looks really solid. Got another shot of the bottom plate on there coming up...

plym49 07-26-2010 08:04 PM

It does not look solid to me.

If you talk to an experienced welder, they will tell you that you can't really tell how good a weld is without x-raying it or testing to failure.

But they are talking about welds done 'right'.

From the photo, it looks like there is poor penetration, voids, spotty coverage and they did not weld the inboard end at all.

Given that your frame was already swiss cheese, and again from the photo, but reinforced by the slim shadiness that you described (who does not know how a spring mounts; come one already) I would be extremely skeptical about this repair.

Suggest you take it to another, known good, certified welder for reappraisal.

The time now is 01:05 AM.
