OTC Tools Wheel Bearing and Hub Assembly Tool

OTC Tools Wheel Bearing & Hub Assembly Tools: Professional-Grade Precision

OTC Tools has been engineering specialty automotive tools since 1925, and their lineup of wheel bearing and hub assembly tools reflects nearly a century of hands-on shop expertise. For bearing and hub service specifically, OTC has developed purpose-built solutions that allow technicians to complete jobs faster, with less physical effort, and without the collateral work that traditional methods demand.

The Hub Grappler™: OTC’s Flagship Wheel Hub Tool

The centerpiece of OTC’s wheel bearing and hub offering is the Hub Grappler Kit (OTC 6575). This kit is the complete solution for servicing wheel hubs and bearings on the vehicle without removing the steering components or knuckle — eliminating unnecessary alignments or the use of a shop press, cutting service time dramatically.

What sets the Hub Grappler apart from generic pullers is the engineering behind its core components. The puller is specifically designed to apply maximum force with minimal effort from an impact gun, while the jaws are designed and sized to properly fit hub applications and can be quickly located on the puller bar without the use of fasteners. This tool-free jaw placement is a meaningful time-saver in a busy shop environment.

Durability is another defining characteristic. The 3/4" custom drive screw coupled with a special equalizer washer provides smooth operation, while proprietary heat treating extends its life 5–10 times longer than similar designs.

The tools along with the manual provide the capability to remove the hub, remove the bearing, replace the bearing, and replace the hub on the vehicle — all in one kit. Six adapters increase application coverage, and the kit also includes a tie rod/ball joint tool and two Ford axle installers.

Comprehensive Application Coverage & Guidance

A rugged blow-molded carrying case keeps tools organized and protected when not in use, and the included application guide is the most comprehensive hub and bearing service guide on the market — developed to be the first tool used in the kit, providing quick reference to the other tools required for the job and eliminating guesswork.

Beyond the Hub Grappler, OTC’s wheel bearing category includes dedicated wheel bearing removal and installation kits engineered for sealed bearings. These tool assemblies remove and install 3/4", 1", and 25mm I.D. sealed wheel bearings using standard wrenches in combination with the tool, and include instructions along with a blow-molded case.

Why OTC for Wheel Bearing & Hub Service?

In 1925, OTC Tools started making reliable tools for technicians, and now, celebrating 100 years, the brand honors a century of quality and innovation. OTC is a professional aftermarket tool brand of Bosch Automotive Service Solutions. That pedigree means the engineering behind each tool is validated against real-world shop demands — not just theoretical performance specs. For wheel bearing and hub assembly service, that translates to tools that protect adjacent components, reduce re-work risk, and keep technicians working efficiently.
