I posted in a couple of other forums about this but so far have had no answer so I thought I'd try my luck here. I have a Gears 5 Xbox One Controller which came with my Gears 5 edition Xbox One X a year ago and recently the left thumbstick has started to drift upwards, and then downwards when I correct it. I have read about dry lubricants you can buy to fix these but they are all North-American based and I live in the UK. My controller is out of warranty so can't be replaced for free. Can anyone advise me of any dry lubricants I can find in the UK that will work or any other fixes that I could also try?
