Front end wobble.

72bluNblu the only shiny part that has popped up so far is the driveshaft. The muffler was dragging on it. I ended up getting that fixed this morning. Before it was fixed the exhaust would shake free and hit the driveshaft. The only other noise I hear when this happens is a resonating hum. I think that is coming from the diff. I was going to take a look at the fluid just to see if the fluid had been changed lately and if I had metal shards breaking free.

If the rear end is making noise you could absolutely have something moving around inside there. If nothing else obvious is going on you will probably need to open up the rear end and inspect the differential. Check the oil first and look for metal, disconnect the driveshaft and see if the play on the yoke is loose first. But a bad bearing, backed off adjuster, etc could absolutely cause that issue.
