Bentolin Axle Shaft Seal Installer 6695 for 1998–2004 Ford Super Duty - Steel, Black Oxide

Bentolin 6695 is a heavy-duty axle shaft seal installer designed to seat vacuum oil seals into the wheel knuckle and onto the axle shaft without damage.

This specialized tool is built to help technicians and DIYers correctly install vacuum-operated front axle seals on Ford Super Duty trucks (1998–2004 F-250, F-350, F-450, F-550 4x4). Using the right driver reduces the risk of seal deformation, prevents hub vacuum leaks that can stop the 4WD engagement, and speeds up the job with durable steel construction and a protective black oxide finish.

How does this installer protect the seal during installation?

The Bentolin 6695 centers and supports the seal as it is driven into place, eliminating uneven force and pinching that damages lips or garter springs. Its machined surface matches OEM seal dimensions so the seal slides in squarely without twisting.

• Precision-fit driver face mirrors factory seal geometry
• Broad contact area prevents concentrated impact points
• Helps avoid tearing, folding, or rolling of the seal lip
• Facilitates consistent, even seating for proper vacuum retention

Which vehicles and applications is the tool compatible with?

This installer is intended for 1998–2004 Ford Super Duty front axles that use a vacuum-operated locking hub design. It’s used when replacing axle shaft seals in the wheel knuckle or when servicing front hub vacuum systems.

• Fits 1998–2004 Ford F-250, F-350, F-450, F-550 4x4 front axle seals
• Works for vacuum-operated front axle/hub applications
• Suitable for professional shops and home mechanics familiar with axle seal work
• Comparable to OEM/OTC 6695 driver tools for the same vehicles

What materials and finish does the tool use for durability?

Manufactured from heavy-duty steel, the Bentolin 6695 is built to withstand repeated impacts from a mallet or press. A black oxide coating adds corrosion resistance and reduces glare while keeping the driver serviceable over many jobs.

• Solid-steel construction for long service life
• Black oxide finish resists rust and surface wear
• Robust enough for shop and roadside repairs
• Machined surfaces maintain fit and function over time

How does using the correct installer affect 4WD performance?

Properly installed vacuum seals prevent leaks that would compromise the front hub vacuum circuit. That helps ensure the vacuum-operated locking hubs can engage and disengage the front drive as intended, avoiding unexpected 4WD failures.

• Prevents hub vacuum leaks that disable 4WD engagement
• Ensures airtight seal seating for long-term performance
• Reduces repeat repairs caused by damaged or mis-seated seals
• Helps maintain OEM functionality of the axle/hub system
