Alright guys, my step dad drove the Rancher into a large pond. I was changing the rear diff. oil today when I knocked the bolt head right off the threaded part. Because vice grips wouldn’t work I had to drill it out. Turns out, the drill knocked the threaded part into the differential itself and it sat right on top of the oil drain hole. I went to Ace Hardware to get this magnetic tool a while ago and I tried it today. I put the tool in through the oil pouring whole and wiggled it down to the bottom. I pulled it out and viola!! I don’t have the package anymore but I do have a picture. This thing might save you a lot of time like it did for me.
