Loud ping then diff fluid started leaking

Samuelh3 said:

I was doing some work on my control arms. As some of you might recall I had my EVO arms backwards. I measured the distance from the base of the Jonnie Joint to the control arm loosened it all the way until it fit in the mount and started righting things down to get it down the the correct length. I started on the drivers side and had the driver tire up with the passenger tire down. The passenger side control arm was about 1-1.5” longer than it needed to be.

As I was tightening the control arm I heard a loud ping and didn’t think much of it as I thought the suspension was just settling. As I went over to the passenger side I suddenly notice diff fluid leaking from the axle tube.

What the heck did I break? Did I over twist the axle? Freaking out a bit here.

Dam, your having a bad week. Maybe the suspension was settling and the leak was already there... but you just noticed it?

Did you shorten the control arm with the other arm still attached? Why position one tire in the air. Sounds like you could have twisted the axle and possibly popped a rosette weld in the diff, or even cracked an axle tube. 1-1.5" difference is putting a lot of torsion on the axle.

Edit: pics would be helpful

Anyone try taking a dremmel to the plug then capping it with JB Weld?

Not sure what you'd be trying to accomplish with this.

Maybe I don't understand the plug. I thought because there is no pressure, you could repair the crack to stop the leak? Please school me on this if I'm missing something!
