Change dust sleeve of the drive shaft

Servus together, would be very grateful if someone had a solution for my problem. With my Volvo V50 T5 Built 2004 (220 hp) with automatic transmission, the dust sleeve on the gearbox side is torn and if I am already there, would like to renew both, also the wheel side. I ordered both cuffs (gear and wheel side) from the company Polar Parts (no universal cuffs). What’s funny to me is that the wheel side cuff is very flexible in front of me. so that I have no worries to get this with a spreader cone over the joint bearing. With the gear-side cuff it looks different, because this is more rigid and not so flexible. Here I fear a problem when covering over the spreader cone even if the spreader cone has been treated with enough lubricant before. As a hobbyist I have only one spreader cone and no spreader with compressed air! Now my question: Is there a different procedure with the Wech I’m only familiar with the method of spreading. Can someone send me a guide? Or, does the spread cone only work with universal cuffs, because they may be more flexible? Greetings Chris
