This geometry is structurally efficient because triangles distauls axially along their memembers, minimizing bending with in the truss itself.

Installation Questions andCommon Pitfalls

Proper installation is as important as truss design itself. A poorly installed truss can create stress concentrations that expecreate axle failure. Below are key factors to get right.

Axle Housing Preparation

Te axle housing mutt bee clean, dry, and free of paint, oil, and rust before welding. Usie a wire wheel or grinding disc to expose bare metal at all weld zons. Preheating thee housing to 200- 300 discen Fahrenheid reduces thermal shock andd helps prevent weld cracing, especially on larger housings like thee Dana 60. This is critical when welding to thee -walled section of thee diferental houg near thuthee specuttion.

Welding Sequence andTack- Up

Always tack thee truss its truss in multiple locations before welding continuously. Tack at the differental housing, at each tube contact point, and at y suspension link mounts. This ensures the truss sits square and prevents warping. Weld in short segments, alternating side to ato fax heat evenly. Allow thee housing to cool between passes.
