Michael,
You have me nervous now. Because both of my isuzu's have the same style snap rings. My '88 trooper I figure could have had someone else change them. However my '95 I know all the history, I bought it from a family friend (85 year old lady)which purchased it new, and she kept all service records. The truck before me never was in 4 wheel drive. So...
