Ford Bronco Window Crank Handle Guide: 1966-1979
Is your window crank handle stripped, broken, or just plain tired? Here’s what you need to know to choose the right replacement for your classic Bronco.
- The most common failure is stripped internal splines, causing the handle to spin freely.
- Identify your year: 1966 models use a set screw, while 1967-1979 models use a hidden C-clip for attachment.
- Aftermarket options range from basic OE-style reproductions to premium billet aluminum handles from brands like Lokar.
- If your window is very hard to crank, the problem is likely the internal regulator, not just the handle.
Symptoms of a Failing Window Crank Handle
A bad window crank handle is usually obvious. Because it's a part you interact with directly, you'll feel the problem right away. Look out for these common signs:
- Handle Spins Freely: The most common failure is when the splines inside the handle strip out. The handle will just spin on the regulator shaft without moving the window at all.
- Broken Knob: The knob you grip can break off, making it difficult and uncomfortable to roll the window up or down.
- Sloppy or Loose Feel: Over time, both the handle's splines and the regulator's splines can wear down, creating a loose, wobbly connection. This can also be a sign of a failing window regulator.
- Visible Cracks: The handle itself, especially original plastic or pot-metal versions, can develop cracks from age and use, eventually leading to a complete break.
Is it the Handle or the Regulator?
If the window is very hard to crank, makes grinding noises, or drifts down on its own, the problem is likely the window regulator inside the door, not just the handle. A failing regulator puts extra stress on the handle and can cause a new handle to strip out prematurely.
Choosing the Right Aftermarket Handle
Finding a brand-new OEM Ford handle for a classic Bronco is nearly impossible. Your options are used original parts or new aftermarket replacements. For new parts, the market is generally split into two tiers: standard reproductions and premium custom handles.
Premium Aftermarket: Lokar
Lokar is a well-known American brand that specializes in high-end, custom parts for classic cars and hot rods. Their window crank handles are a significant upgrade from the original factory parts.
- Material: Lokar handles are machined from solid billet aluminum, making them much stronger than the original pot metal or plastic handles.
- Design: They come in various modern styles (like Truss or Windowed) and finishes (polished, brushed, black), allowing for a custom look.
- Installation: Lokar uses a superior mounting system with a splined adapter. This provides a secure, wobble-free fit and allows you to adjust the handle's final resting position.
- Cost: As a premium product, they are more expensive, but offer a lifetime warranty and are made in the USA.
A Note on Fitment (1966 vs. 1967-1979)
The 1966 Bronco used a unique window crank handle that attached with a set screw on the side. Later models from 1967-1979 used a splined shaft and were held on by a hidden C-clip. Aftermarket handles like those from Lokar typically use a universal splined adapter that works for all years from 1966-1979. Always confirm fitment for your specific year before purchasing.
Replacement Cost Comparison
Replacing a window crank handle is an inexpensive job you can easily do yourself. Labor costs at a shop would be minimal, likely part of a minimum one-hour charge.

|---|---|
| New OEM (NOS) | $100+ (Very Rare) |
| Used OEM | $20 - $50 |

Frequently Asked Questions (FAQ)
How do I replace the window crank handle?
For 1966 models, you simply loosen the set screw on the handle and pull it off. For 1967-1979 models, you need to remove a small C-clip located between the handle and the door panel. You can use a special removal tool, a shop rag hooked behind the handle, or a small hook tool to pop the clip off. Installation is the reverse. The entire process takes only a few minutes.
Do I need a special tool to remove the handle?
A special forked tool makes removing the C-clip on 1967-79 models easier, but it's not required. Many people successfully use a rag or a small pick to hook and pull the clip off. For 1966 models, you only need a screwdriver for the set screw.
My handle hits my leg or my roll cage. Are there other options?
Yes. Some owners with aftermarket roll cages seek out shorter handles for better clearance. Premium brands like Lokar offer a clean, low-profile design and allow you to clock the handle in any position, which can help solve clearance issues.
Are there any recalls for the window crank handle?
No, there are no recalls or Technical Service Bulletins (TSBs) from Ford or the NHTSA for the window crank handles on 1966-1979 Ford Broncos. Any issues are due to normal wear and tear over the vehicle's long life.
