Default IRS damage

How bad does this IRS damage look to you? The brace around that wishbone is bent to the right on both sides of it. Also that wet spot shows me that the cap to the diff. got pulled towards the back of the car somehow.

I would replace those brackets. There could also be some stress cracks in the aluminum, most likely around bolts that you can't really see yet. So did you get rearended?

Glock,

I would pull the whole rear and see what you have, that leak tell you that everything shifted, whether it was the pumpkin or the brace is a guess until you pull it and check the frame where rear brace mounts. That area of the car is strong but with a good whack you can cause problems, hopefully it just moved the pumpkin portion in which case you can replace all the brakets, make sure all your links are straight and go on your way.. just make sure you get that frame looked at and measured from every possible angle.
