Torsion bar reliability

[Luk88]

This is an odd question, I'm new here so I don't know if there's a thread on this or not, just wondering if anyone has had problems with the torsion bars on their trucks and wear someone would buy new ones

 

[Frank Enstein]

They are generally very reliable. If they sag a little snug them up. If they sag again then replace them. One crank up every 200k or so should be fine.

I've never heard of them wearing out.

 

[Schurkey]

They're like every other piece of steel. Sooner or later, they'll wear out.

This could take a zillion miles. Unlike coils, torsion bars tend to have adjustable mountings that can accommodate some yielding of the steel shaft.

Beyond yielding, they could fail from corrosion or work-hardening. Can't say that either is a common issue.

I bet most torsion bars get scrapped due to bending in a collision.
