Focus problem (Noisy sound) In Canon Zoom Lens EF 28-80mm 1:3.5-5.6 II

In this video I will try to repair the focus problem because the focus gear has a very noisy sound in my Canon Zoom Lens EF 28-80mm 1:3.5-5.6 II.
The gearbox cogwheels are made of plastic and some of them are missing some grease, so I use Lithium grease to grease the axle ends only and it works as it should.
