YJ - rear upper shock mount broken

This happens yesterday and I wonder how difficult is to fix it. I'm ordering a set of shocks mounts from AUTO RUST (Quadratec sell them too) so as soon as they here I'm planing to weld them. Here is what I order

My broken mount

Doesn't look to hard, cut the rest of the old shock mount off and grind the welds flush with the frame and weld the new brackets on. Possibly fix the rust on the frame?

Fix that frame rot before welding new mounts in. Looks like you wouldn't even have material to weld with on at least one side.

Thats a common place the frame rusts out due to the way shock mounts are designed,water sets in there at all times and rots it out.
Cut off whats left of the shock mount..then cut out all the rotted out area on top the frame,replace/weld with new,can be 1/8" or bigger(thats all the thickness these frames are) or maybe 3/16" plate or bigger..whatever you have laying around..then weld the new shock mount on..
After you weld the new shock mount on,you can do what i did with several i did for people last summer replacing those bad spots and fabricate a small peice of plate to fit inside the shock mount and weld it on an angle upwards towrds the shock mount..weld the low end on outside frame part,and the other end welded higher up on the shock mount and weld all the way a round,,this will prevent water from sitting in there again and causing the same issue again down the road....In other words you are going to box the open side of the shock mount in sealing it off where water commonly sits in there......i did 4 of these last summer for local jeepers.

Ok this is what I'm planing to do: Will clean the area then weld this sleeves and the mounts on top. (you can get them here: http://autorust.com/store/jeep/rear_..._set_art-122-s)

Ok FIXED IT but man what a PITA

Here are some pictures, it was BAD




We used a piece of an angle 3/16"




Then welded all around




Now I need to make plans for the other side

Good job!...that little pocket on top is where i was saying i boxed it in totaly enclosed to prevent mud from caking in there and staying there holding moisture and the reason why it's common to see that area rotted away...you have an oval hole in your new bracket on the bottom side which should be fine if you make sure to hose it out thoroughly once in a while when washing...as a suggestion i'd maybe put some heavy red oxide primer and an industrial rustoleum in there too,or even a little leftover bedliner if you happen to have any...

I did 3 of those areas last summer for local jeepers with YJ's..2 was them driving the Jeep to my house and one trailered a bare frame he just had sand blasted..that was a gravy 1...the other 2 was a real PITA to get to everything while the jeep was fully assembled...

Again..you did a great job!.......

Thanks man, I really appreciate the good comments from an experienced members, yeah I will definitively put some primer in there real soon. I have a quart of CHASSIS SAVER from Magnet Man but I will order a gallon to do the whole frame and underneath the Jeep, also want to get some heat resistant paint to do the muffler and cat. Now I will make plans to the the other side which is more kinda delicate because of the fuel filter and lines hanging right there, but if you take good precautions can be done. Thanks again.

Lets see how long it last

That sucks! Even though you've already replaced it with another manufacturer, I'd contact ART about the failure. They've always seemed like stand up folks in the dealings I've had with them. Granted, it has been during purchases and not during a conversation about the failure of one of their parts. If you do give them a call, let us know what happens. It's good to know how companies are willing to back their products. Did that happen while you were wheeling, or just normal every day driving?

Are your shocks proper length for the springs you have?

I guess so, the leaf springs are 4" Rough Country and the shocks are Rubicon Express for 4.5" lift................

Check your Bump stops at full clock of the suspension,if the shock bottoms out before you hit the bump stop,it could cause this...

The reason why i say this,is because on one of my old first generation bronco's i had bought a 3.5" lift kit including shocks and everything,was supposed to be a bolt on with no mods..i ruined the set of rear shocks that came with the kit because they bottomed out before they hit bump stops that came with the kit...

It's always a good idea to check everything yourself after a lift,,never beleive everything is going to be "OK" just because the company/manufacturer says it will be...
