E-cowlboy Axle Shaft Seal Installer for Ford Super Duty 1998-2004 — 6695 Vacuum Hub Driver, Hardened Steel

The E-cowlboy 6695 axle shaft seal installer is a hardened steel tool designed to seat vacuum-operated front axle seals accurately and damage-free in 1998–2004 Ford F-250, F-350, F-450 and F-550 4x4 wheel knuckles.

When servicing the front axle on late‑90s and early‑2000s Ford Super Duty trucks with vacuum-operated hubs, correctly installing the axle seal is essential to avoid hub vacuum leaks that can stop 4WD from engaging. The E-cowlboy 6695 replicates the OEM driver geometry, letting a single technician press a seal squarely into the wheel knuckle and onto the axle shaft without nicking the sealing surface or the knuckle bore.

How does this tool speed up seal installation?

Instead of improvising with mismatched sockets or hammering directly on the seal, the 6695 provides a dedicated driver that centers and guides the seal for a straight press. That reduces time spent on trial and error and eliminates repeated removals and reseating.

• One-piece steel driver for consistent seating depth
• Tool bottoms out in the knuckle to ensure correct final position
• Works with press or mallet while protecting the seal lip
• Installs both the axle-side and knuckle-side surfaces in one operation

Will it fit my Ford Super Duty truck?

This installer was made for Ford F-250, F-350, F-450 and F-550 model years 1998 through 2004 that use vacuum-operated front axles. It matches the Ford Tool 205-830 and OTC 6695 dimensions, so it’s compatible where those OEM tools are specified.

• Intended for 1998–2004 Ford Super Duty 4x4 front axles with vacuum hubs
• Comparable to Ford Tool 205-830 and OTC 6695 for cross-reference
• Single-tool solution for common front axle seal sizes on these models

What materials and finish protect the tool in a shop environment?

The installer is machined from heat-treated steel 45 for toughness under repeated use. A black oxide finish helps resist corrosion, minimizes galling against the seal, and gives durable service life in a busy garage.

• Heat-treated steel 45 core for impact resistance
• Black oxide coating to reduce rust and surface wear
• Precision machined faces to avoid deforming seals during installation

How does this tool prevent damage and comebacks?

Properly seated seals stop vacuum leaks at the front hub, which are a common cause of 4WD engagement failure. Using the correct driver eliminates uneven seating, torn seal lips, or scored knuckle bores that lead to repeat repairs.

• Ensures seal lip stays square to the axle shaft during installation
• Prevents knuckle bore damage from misaligned striking
• Reduces the chance of shop comebacks due to vacuum leaks

Who is this for: Mechanics, fleet technicians, and home DIYers who work on late‑90s to early‑2000s Ford Super Duty 4x4 front axles will find the E-cowlboy 6695 indispensable. If you perform hub, axle, or wheel knuckle service on F-250 through F-550 trucks with vacuum-operated front axles, this tool saves time, protects components, and aligns with OEM tool functionality. The package includes one axle shaft seal installer, backed by a 30-day return option and a 12-month warranty for risk‑free purchase.
