Hello, if the rubber is not damaged when removing it, no adhesive is necessary, check the condition of it and if it is OK, insert it carefully into the cavity and then adjust the clamping nut so that the rubber expands and prudes the tightness, now If you notice damage to it, a silicone sealant and carefully adjusting it can solve it. Regards P / D to change bearings it is not necessary to remove the resistance, just disconnecting the terminals is sufficient.
