where the trailing arm is connected to the sled it is loose.
the bolt is still tight, but the trailing arm moves around.
it almost looks like the weld is broke?
my question is,is it still safe to drive leaving it like this?
2003 xcsp500 thank you

You can't drive it at all!
It is not that hard to replace yourself but you should never use a hand pop rivet gun the rivets will never stay solid. Borrow an air riveter and you need belly pan rivets and and bulkhead rivets a 90 degree drill is the best but you can use a regular one and a good 3/16 drill bit . I can do one in about two hours but it will take you at least twice that.
