How can you tell when your torsion bars are shot?
My truck has been taking sharp turns horribly as of late -the weight distribution feels off when I take a sharp turn at speeds of 15+mph. Something also feels weird when I hit bumps in the road, it hits the bump and seems loose or off balance for a split second.
I have had the truck to two different places who have checked out the front end. I have been told that the ball joints and the tie rods are fine, the wheel bearing/hub assemblies were just replaced, so I'm thinking it would be either related to the shocks or the torsion bars.
I am eventually going to dismount the shocks and see if they still have any dampening to them, but I'd like to know if there's any way to check out the torsion bars as well.

The sway bars look fine, they're in tact and they don't budge when I pull on them. What happens to the bushings on them, do they dry rot? I suppose I could check that out.
My shocks aren't stock, they're Rancho RSX shocks, but they've been on the truck now for 4+ years and through a bit of rough wheeling. What exactly is the bounce test?

like everyone else said, i would think it would be your shocks, or swaybar... the bounce test is easy, put all of your weight on the fender, fast, to try to compress that corner of the truck, then right as it gets to the bottom of where it's going to go, jump off, and see how many bounces it gets, a good shock, shouldn't bounce at all, it should come back up to ride height and stop, but most shocks are somewhat worn... if it bounces once or twice, it's not a big deal... it's when you can go for dinner, and your truck is still bouncing, that it's an issue... if you want to, you can always make it bounce a few times, when compressing it, to give it a higher bounce, to recover from... so push down 2-3 times then see how long it takes to stop...

Torsion bars don't just get 'shot'. They'll still keep working as they should for on and on and on......Good way to know they're on their way to 'crappy' condition is you're bars are maxed out and you've got a massive rake because they've sagged so much. You could be dragster raked and they'll still be doing their job.
I'm leaning more towards those 4 year old shocks or the above mentioned lower BJ's. I just swapped out my Superlifts that I installed brand new about 25-30k ago...they were shot and mushy with no rebound. No seal breakage....I assume they just turned into foam inside. But back to BJ's....Are they originals? Do you have more than 75k on the truck? If so, I'd say they're toast or close to toast anyway. Even if the truck is on the ground, you can't check condition of them. Truck's gotta be in the air and suspension at droop. When I did my BJ's at 80k or so, all were still pretty good and fairly tight. But my goodness the results of new BJ's was amazing. Rule of thumb on these 98+ SLA trucks, by 100k, you should have new BJ's in it IMO.

Shane, I'm at 115k with the original ball joints. Two different places told me that the ball joints were fine, but I see what you're saying there. How difficult was it to change out the ball joints yourself?
Saturday if I have the time, I'm going to pull off the shocks and see if they've got any compression left to them.
