There is no such thing as a casual suspension inspection. The safety of the driver depends on the condition of the tie rods, ball joints and other suspension components.
We’ve all heard the term “Active Suspension,” but a shock or strut doesn’t really go anywhere – so what makes it “active?”
From Audi to Toyota, import nameplate manufacturers are using more aluminum for suspension components. An aluminum component is as strong or stronger than steel or cast iron but what sets aluminum apart is how it fails.
Andrew Markel covers how suspension component fasteners are secured using mechanical attachment methods like castellated nuts, nyloc nuts and torque-to-yield fasteners. He also discusses chemical solutions like thread locking compounds.
On 2014-2017 Ford Expedition models with the Vehicle Dynamic Suspension, the system looks at a lot more than just the height of the vehicle to control the pressure in the air springs and the valving of the shocks.
When you consider how front suspensions have evolved from straight axles to independent designs, the tie rod has had to adapt to new angles and geometry.
For every 10% reduction in vehicle weight, there is a 5 to 7% fuel savings.
What do some ball joints, tie rods and suspension components have in common with engines? The answer is Torque-to-Yield (TTY) fasteners.
Jason Stahl discusses the role of ADAS in suspension repair and why shops should remain conscious of advanced safety systems during routine maintenance.
In this Tech Minute, Andrew Markel covers everything about TTY bolts and how their build could affect your next suspension repair.
