Loading 3D model...
The Left Tie Rod Arm 31131136871 for BMW E31 is no longer available from BMW. I scanned the part using CR Scan 01. The model has the correct dimensions. The holes may require improvements. All relevant mesh, step, and FreeCAD files are included.
You can 3D print the model to ensure it works, then CNC print it from cast iron or steel for use on the vehicle. The original part is made of cast iron.
