          Ok so a drift is something to push the bearings in that is the same size as the bearing race u are trying to put in.
          If you were trying to put a 20mm bearing in a 20mm hole you could use a 20mm socket to knock it nicely into place with a hammer without damaging the bearings 👍

              Ah I see,get a long screwdriver and put it through one bearing so it touches the inside of other bearing and slowly tap it out,make sure to move the screwdriver so the bearing comes out strait

                  I can't recommend using the suggestions provided here.

                  The last thing you are going to want is for the front wheel bearings to collapse down the motorway at 70+ mph.

                  A key point missed off the drift is that you must ensure the drift is of softer metal than the metal you are hitting.

                  Sockets tend to be Chromium Vandium, as such incredibly hard. You will damage the bearing long before you damage the socket.

                  So you want to use a soft drift, like ally, that will take the brunt force of the impact.

                  The wheel bearings should be pulled out using a hydraulic puller.

                  Using a screw driver, or drift, and tapping it out risks damaging the hub. Which will render the wheel useless.

                  There are ways to do it. The proper way is to heat the wheel up and use a puller to carefully extract the bearing. Most don't do this as it's a fine balance between heating and distortion.

                  Definitely crank cases should be heated before bearings inserted.

                  Always Originate, Never Pirate!

                    Use a Brass flat edge drift if you can.

                    You can heat the hub, but you shouldn't have to.

                    The Wheel bearings are not toleranced like crank journals, for most older offroad style hubs, you can drift bearings no trouble.

                    Makes sure you cool the Bearing before installing them into the hub, that's when you damage the outer race,

                    If you have press, use that tho!

                    Keep it real

                      Put the bearings for hour or so into the freezer 👌
