OTC wheel bearing locknut sockets are formed from high-strength steel that is resistant to rounding out under high torque loads. Designed for use with 3/4 inch, square-drive MANUAL tools only. NOT intended for use with impact tools - use with impact tools will void the socket's warranty. 6 point, 3-1/4 inch (flat to flat) opening size. Measure locknut from flat to flat to determine socket size needed. 5 inches deep to ensure spindle clearance. Value is at the core of the OTC tool and equipment portfolio. For a simple repair or the most complex drivability concern, these award-winning tools universally solve problems faster, and at better value, than any other product line available. Whether it’s a specialty tool or unique piece of service equipment, OTC provides top solutions to modern automotive service challenges while increasing technicians’ productivity and shop profits.

I used this axle nut socket to remove the nuts that hold the hub onto the rear axle housing on a Mack truck.

I needed a 4†socket, but couldn’t find one, so I bought this one because of the reasonable price. With some slight modifications, I can now use this anywhere from a 4†to a 4-1/8â€, 8 sided axle nut. Very durable

We have some of these floating around work as shop provided tools, not sure of the exact brands. Somehow the shop neanderthals end up mangling the hell out of them to the point of being unusable. Finally bought this one for myself, and it works without any issues since my personal tools don't get drug through Compton.

Delivery was prompt, it looks exactly as depicted in the description and appears to be of good quality. I used it to remove and reinstall the inboard axle bearing nuts on a Freightliner-Tripple E diesel pusher motorhome chassis and it worked well.

Bought it to tighten large tractor axle nuts. Required me to cut off the square drive and weld a 2†pipe to it to fit over the axle shaft. A 24†pipe wrench with 6’ long pipe over the end and jumping on the end to move that nut 1/8 turn at a time and the socket took it! WELL MADE!
