I have noticed my LWB 94 Bighorn bottoms out a lot more off-roading than it used to so I did a measure up against another one and found mine has sagged about 1.5 inches in the front. It feels the same to drive on the road as it always has, and all the suspension is factory. Both front corners sit at the same height.
It definitely used to sit normally. It does have a hard life off-road though.
Just wondering what it might be? I have had a good look around under there today, nothing seems to be out of shape. I've taken the shocks out and they are quite old, but I'm thinking it's more than likely something with the torsion bars. I don't want to wind them up in case something else is the issue.
Any ideas?
