OTC Wheel Bearing Tools 1921 Editorial Review
The OTC 1925 Wheel Bearing Locknut Socket is a heavy-duty tool designed to fit a specific range of nuts. Customers who reviewed the product have used it for various applications including removing but on steering gearbox, taking off and putting on spindle nuts on a 40' gooseneck trailer and using it to remove and put on outside dust cover for oil bath axles. The accuracy of the fit and its durability were repeatedly praised, with one customer stating it far surpasses any other sockets of other manufacturers in their shop. However, there were some questions about compatibility with specific nuts and axels, and some users pointed out that locknut sockets are not intended to be used as traditional sockets.
