Help! Squeaky gears!

[LEEHM]

Hello, I hope you are all well

I am posting in the hope that someone might be able to offer some advice! My rear derailleur is making a squeaky noise when shifting up to a larger cog!
Any idea on how I can fix this?
Thanks and have a great day

Send a video of the derailleur, not the shifters!
Try oiling the jockey wheels.

Hey Mike I think the squeaky noise was coming from the cable! Anyway, I decided to stop making the matters worse by trying to fix it myself and cycled to the bike store…. Of course by the time I got there, the noise had disappeared! Felt like a right fool!

Thanks for replying 👍
