Freightliner FLD SBA Dash Knobs

Frequently Asked Questions About Freightliner FLD SBA Dash Knobs

What are dash knobs used for on the Freightliner FLD SBA?

Dash knobs are the small control handles used to operate functions on the dashboard, such as headlights, dimmer switches, heater and A/C controls, wiper settings, and vent adjustments. They thread or push onto the metal control shaft behind the dash panel and let the driver adjust these systems without touching the shaft itself.

Will these knobs fit my specific Freightliner FLD SBA model year?

Dash knob designs can vary slightly across production years and depending on which factory control panel was installed on your truck. Before ordering, check the thread size or shaft diameter of your existing knob, and compare it to the fitment details listed on the product page. If you are unsure, removing your old knob and measuring the shaft it attaches to is the most reliable way to confirm compatibility.

What materials and finishes are these knobs available in?

Freightliner FLD SBA dash knobs are commonly offered in durable plastic or chrome-plated finishes to match factory dash trim. Chrome versions are popular for drivers looking to upgrade the interior appearance, while plastic knobs closely replicate the original factory look and feel.

How do I install or replace a dash knob?

Most dash knobs simply pull or unscrew off the control shaft, depending on how the original was attached. To install the replacement, line up the knob with the shaft and either push it firmly into place or thread it on until snug. No special tools are typically required, but be careful not to overtighten, as this can strip the shaft or crack the knob.

Why is my dash knob loose, cracked, or not staying attached?

Over time, the plastic mounting point inside a knob can wear down, crack, or lose its grip on the control shaft due to age, sun exposure, or repeated use. If a replacement knob still feels loose after installation, check the shaft itself for wear or damage, since a worn shaft can prevent even a new knob from seating properly.
