You have the Twin-I beam system as it is a two wheel drive. Monobeam is the solid front axle in the 4X4's. Use 2CarPros anytime, we are here to help. Please tell a friend.

Hello, I'm Danny.
No, your front suspension is not Monobeam but called torsion bar style suspension. I've attached a picture below. Hope this helps and thanks for using 2CarPros.

Suggested Repair
Identify the front suspension by drivetrain rather than replacing parts. The 2005 Ford F-350 two-wheel drive uses Twin-I-Beam; monobeam is the solid front axle used on the 4x4 models. The 1989 Chevrolet K3500 4x4 uses torsion-bar front suspension, not monobeam.
Conversation Summary
The owner of a 2005 Ford F-350 Super Duty crew cab with a 6.0L diesel asked how to tell monobeam from twin-beam suspension. The expert said a two-wheel-drive truck has Twin-I-Beam, while monobeam is the solid front axle used on 4x4 models. A second owner then asked about a 1989 Chevrolet K3500 4x4 and was told it uses torsion-bar front suspension, not monobeam. The owner confirmed that matched the truck.
