DearChan Universal Wheel Hub Puller OTC 7394 Replacement — 3-Arm Adjustable, Heat-Treated Steel with Fine-Thread Center Bolt

DearChan Universal Hub Puller is a heavy-duty wheel hub removal tool engineered to extract press-fit hubs, tapered-axle hubs, and rear drum brake hubs without harming wheel studs or components.

If you work on passenger cars, light trucks, or fleet vehicles, a reliable hub puller speeds repairs and reduces risk of damage when removing stubborn hubs. The DearChan Universal Hub Puller replaces OTC 7394 with an adjustable three-arm design, heat-treated steel construction, and a fine-thread hex-drive center bolt so you can apply controlled, straight pulling force for most common hub assemblies.

How does this tool remove hubs that are stuck on tapered axles?

The puller centers on the hub face and applies axial force via a fine-threaded center screw, drawing the hub off the taper evenly. Its three adjustable arms clamp behind the hub flange, which prevents slippage and focuses the force where it’s needed instead of stressing studs.

• Fine-thread 1-1/8" hex drive center bolt for gradual, powerful extraction
• Three adjustable sliding arms engage behind hub flange for even pressure
• Striking wrench included for controlled impact when hubs are seized
• Designed to avoid bending lugs or distorting hub faces

Will this fit the hub sizes on my car or light truck?

Yes — the adjustable arms extend to a 7-1/2" diameter bolt circle to cover a broad range of passenger and light-truck hubs. The universal geometry is intended to adapt to common bolt patterns and hub diameters found across many makes and models.

• Arms slide to match multiple bolt circle diameters up to 7.5"
• Three-arm configuration suits uneven or off-center contact points
• Works with press-fit rear drum brake hubs as well as tapered axles

What materials and construction make this tool durable?

The DearChan puller is forged from heat-treated heavy-duty steel to resist bending and wear under repeated use. Corrosion-resistant finishing and careful selection of components mean the tool maintains alignment and function even in busy shops.

• Heat-treated forged steel body for high tensile strength
• Corrosion-resistant surfaces for longer service life
• Precision-machined center screw to ensure straight pulling action
• OEM-spec manufacturing and quality checks for reliable performance

How does the design protect wheel studs and hub faces?

The puller’s three arms clamp behind the hub flange so force is directed away from wheel studs and lug holes. The straight-line center screw pull minimizes twisting and bending, lowering the chance of damaging mounting surfaces during hub removal.

• Arms engage hub flange, not lug studs, to prevent stud deformation
• Fine-thread center bolt delivers controlled, incremental force
• Stable alignment reduces side-loads that can warp hub faces
• Includes striking wrench for shock-free or impact-assisted use

Who this is for: The DearChan Universal Hub Puller is aimed at professional mechanics, enthusiastic DIYers, and fleet maintenance teams who need a versatile, durable tool for removing press-fit and tapered wheel hubs. If you regularly service wheel bearings, rear drums, or assemblies prone to corrosion and seizing, this puller helps speed jobs while protecting hub and stud integrity. It’s a practical replacement for OTC 7394 and similar tools when you want robust construction, adjustable reach, and reliable straight-pull performance.
