Please confirm or deny my theory
Hello, my TV is a 2008 Nissan Titan king cab 4x4. About a month ago I pulled my trailer about 1150 miles but also had a 550 lb riding mower in the bed. The trip was fine, no issues, pulled like a champ. A few days later and no longer towing my TV made a loud clunk toward the rear end while making a left turn. It's almost feels like the rear passenger tire momentarily losses traction and you can feel the whole trucks rear weight shift. It will only happen if I am getting on the gas pedal a good bit. I did a bunch of forum and non forum searches. There are basically two things is may be, the differential is going out or a cracked leaf spring shackle. When I get under the truck I can't see any problems or move anything around on the Leaf springs. I pretty much determined that it had to be the differential UNTIL, I was on a very twisty road and the clunk and thump happened on a tight right hand turn under braking! And it was the worst it's ever happened, I though the rear end was gonna slip out from under me. So my question is, does that pretty much rule out it being the differential? I am hoping for both money and times sake it means it's a busted shackle. Thoughts?
