Tip: wire up the CA to keep it out of the way. Wonder why guys don't use a chop saw with steel blade in there and split that sleeve. Won't hurt if one marks the diff side as the sleeve goes back in new.
So your death wobble was ball joints. Was it obvious, or did you do process of elimination? I get occasional death wobble too. trying to find why..... We're from Maine too!
Was process of eliminating causes. The two big times I had it was ball joints and other stuff can wear out if not fixed in time. Check ball joints, front wheel bearing hubs, un bolt track bar and check bushings condition. Check tie rod ends, drag link etc.
