Install Pinion Bearing Without A Press, Just Heat And Cool

Installing our Pinion Bearing without a Press could not have been easier. We heated the bearing in the oven, cold the pinion in the freezer, and with no effort, the bearing was on. This saved us money on our Jeep Gear change project because we don’t have a press.

We were skeptical this would work, bearing always feel so tight and take so much pressure to get on. When we pulled the pinion out of the freezer, the bearing out of the oven, we just dropped the bearing over the pinion and it was on. Was amazed at how quick and easy this was, did not think the cold would contract the one metal that much, and the oven expand the bearing to easily slide on.

See the install of these bearing on our Jeep Mods playlist, we are changing the gears on the jeep from 4.10 to 4.88 because of the larger tires.
