Broken shock mount on my jk WTF...

So, I just thought I'd put this out there and see if anyone has had this problem and possibly find out why this happened. I have only had my jeep for about 5 months now, It has a 2.5" lift with 36" tires. The lift was done at the dealer and being so, the damage to the shock mount will be repaired by the dealer. But I'm kinda confused because I haven't been doing any serious off-roading of any kind. The most I have done was maybe 1/2 a mile down a normal dirt road last weekend. Nothing that should have stressed the supposedly rugged suspension the 2012 JK has. But regardless, when i got in to the jeep the next morning and pulled out of my driveway I noticed a alarming clunking noise from the rear of my jeep. After inspecting it I was surprised to se that the passenger side shock mount that attaches it's self to the frame had broken away. The broken bracket is just that, where the bracket welds to the frame that part is still there and the part that holds the shock is still attached to the shock there just no longer attached to one another. So the bracket appears to have a stress load that that has resulted in demise. My concern is that though this is covered under warranty now, what has caused this and is this going to happen again? Further can this repair be made in such a way that I won't need to worry about it an alignment issue? If any of you experts out there have any helpful information I'd love to hear it. I don't want to get screwed by the dealership a seconded time around. Thanks.....

Your "supposedly rugged suspension" has been altered. Your broken shock mount could be anything from improperly mounted shocks to improper length shocks or just a weak mounting point that was stressed by the larger than stock tires. When you mess with your suspension, things sometimes break. Get used to it. The next high stress points will be your front axles and ball joints.

Any suggestions on making this better? I mean I am not total new to jeeps but I find it hard to be leave that the driving I have been doing would cause this in just 5 months of weekend joy riding in the city.

There are ways to support and strengthen your front axles, but 36" tires will stress evertyhing. Did you add a swing out tire carrier or is your spare on the stock mount?

Man I would love to see some pics, I'm trying to think how the break would occur frame side so cleanly. I thought the rear frame brackets (the upper ones) was simply a slot cut in the metal, with screw holes drilled out, and nuts welded onto the opposite side. I've been putting my jeep through some real abuse, and my shock mounts don't show any sign of damage. Chances are, you just had the friday build right before lunch, and just had a crappy weld

Or the wrongs size shocks for the lift. The OP has given us zero details other than it is 2.5".

I would suspect that even if he had shocks too tall for his lift, if anything was going to break it would be the shocks, not the shock mounts. Unless they replaced his rear shocks with a piece of aluminum stock and didn't tell him. But that does beg the question, does the OP have the right size bump stops, or bump stops at all?

Look into these

Synergy Suspension*::*Synergy Suspension Jeep JK Rear Lower Shock Mount Kit
those are the lowers (which make a million times more sense to fail), he was saying the frame side came off (by which I assume he meant the uppers)

I wish I had taken a photo but I didn't think about it until after the tow truck had already left with it. And yes it's the upper, and I'm not sure but I think they just left the stock shocks on wit the lift.

if its the stock shocks, they may have added an extension. do you know what lift it is? also, sounds even more like friday before lunch quality control

But I like all the attention this is getting. I really am grateful for everyones help. I just can't see this as being something you should expect to happen. Especially being I haven't taken it of road yet.

I'm not really sure I bought it with it already lifted, I know that the dealer ship sent it to southern off road specialist, so the people doing the lift should in theory have done everything correctly. The only think I know that was done was they put 2.5" spring litters on them, I'm sure that's not what they are called but it's a rubber block put on top of the springs. I asked the dealership to send me a picture of the broken part.

I read a thread about something like this and the fix involved replacing the Jeep's entire frame. The body shop wouldn't weld the frame because of special steel iirc.

Shocks were too short? Full droop pulled it loose? Not enough info to go on. I do agree that 36" tires are adding more stress. If you have a stock D30 up front start saving for mods to strengthen it.

So I have got an update from the dealer. They have sent my jeep back to the company that installed the lift kit and they have informed me that the weld that was made by the factory wasn't done very well something about a spot weld broke allowing for the flexing that lead to it breaking. He said that the will weld it back on using the original bracket and that it will be plenty strong enough that I'll never have these issues again. He was nice enough to send some pictures along so that I could share them with everyone. I'm not totally convinced that this problem has been totally resolved, something about the way they were answering my questions makes me think there playing a whole lot of "CYA". the angles of the pictures don't really show much but from what I remember seeing when I looked at it there was a straight line break on the bracket and welding it back makes me think that it will always be weak being it won't be heat treated any longer. Am I worried about a lot of nothing here or do I have a point?

yeah, I'm sticking with the original answer of "factory up" theres not really a good way to break that. Even if it was the wrong shocks, bad coils, heavy tires, anything, that bracket should not just come off like that. see if while theyre welding it back on, if they can look at the other one as well. this is coming out of the dealers pocket to be filed as warranty work for sure

If it were me, I'd want to know exactly who they contracted the work out to and exactly what lift and components were used.

The pics are small however from what I can see it looks like a faulty weld. No penetration on the factory weld. The bracket did not fail the weld did. I would have no issue re-welding the bracket providing the person doing the welding knows what he is doing. Not a difficult weld but you do need to make sure the heat range is in check.

All I know is that they used a lift kit from Teraflex, the company that's doing the repair is well known in the area (southern off road specialist). I talked to them today and I feel like they know what there doing. But no one would answer me about what various lift components were used. I think they my upset me with how little they did for the amount the dealer stuck me with. When I got the jeep they charged me for 10 grand in upgrades. It's a nice jeep but I think for 10 grand I could of done a sheit load more than what I got. But never the less I'll be happy if it gets fixed.. I thinking I'll take it to another off road company and have them give it a once over and see if I got what I'm suppose to have. I'm finding owning a jeep is becoming a big learning experience. I won't lie I kind of dig it. thanks for your help by the way....

If that's true some one needs to check the calibration. And JK owners check your welds...

Then you should see the word Teraflex on there somewhere. If I'm not mistaken Teraflex shocks are white.

Teraflex coil springs will also have "Teraflex" printed on them and it is easy to see.
