Lots of noises coming from Torsion Bars? H3

[H32NV]

Does anyone else get a lot of "clanking and clacking" after doing the torsion-bar lift for their H3's? Mine is really noticeable with the windows down, and I think it sounds like its coming from the torsion bar linkage near the center of the truck, underneath the cab. Maybe I'm wrong about the location, but it seems like there's a lot of "clicking" going on when i go over even just small little bumps on paved roads, but especially when offroad. Not loud enough to hear with the windows closed tho....

It could be something on the passenger side moving around??? lol
Your tie rods after lifting or pushing up more rather than just in and out.
Sorry, it's my job to say that.:giggle:

Could be the upper a arm hitting the positive stop, from being at full extension.

The A-Arms arent close to being at full extension, but it makes quite a racket. something is loose... or maybe the OEM torsion keys are clacking something

I believe Laguna had issues with torsion bar noises, though I think his were at the front where they go into the lower control arms. One common mid-truck noise is from the parking brake cable along the driver's side frame, including at the mount ahead of the rear tire.

I don't know the mount of the torsion bar well enough to suggest what could be making noise there. My aftermarket exhaust periodically gets out spec and hits the frame in this area. I never got extra noise except for what Hunner correctly stated - tie rods pushing up on the steering rack causing noise and thumps. But those noises are pretty easily determined to be up front and it's more what you feel in the pedals and steering wheel vs. hear.

if it is where they go into the lower control arms, then this would make total sense. The parking brake cable is pretty secure, I def dont think its the parking brake cable. I dont feel anything in the pedals or the steering wheel, its just when i go over small bumps, its like something is loose and knocks around then it moves...

Torsion bars and the like arent covered under powertrain are they?

Do you feel it in the floorboards and through the steering wheel? I would also look at the front diff rear mounting point. When that bushing goes, it can make a lot of noise that sounds like it is coming from the front wheels.

Def nothing to do with the front diff. That thing is built so solid now, with a new modified crossmember and mounts, that its just not possible. It could be just really loud CV's that are loose and clanky, but I feel like the timing happens whenever i go over bumps, the torsion bar explanation would make perfect sense in this case. I should post photos of my new diff build and the crossmember that went with it, I went a little crazy and ended up fabricating a new crossmember with a hole drilled sideways through it, press-fit a poly bushing, and then mounted a U-bracket to the diff, and sent a bolt through the U and the poly bushing. So instead of the load being applied axially(along the bolts length) as is the case with the OEM bushing, this new method applies the load radially, sideways across the bolt. Its much stiffer, but still has a little give because the walls of the bushing are pliable. I'm thinking that the case that sounds most probable is the torsion bar at the lower control arms, but I'm open to hearing more ideas! I at least have an idea to look at now!
