Buzzing D5

[Tackle_Berry]

So today my d5 is making a loud buzzing/rattling noise on speed 3, but when i change the speed to 1/2/4 and 5 it goes away. Any ideas?

Current setup: (been like this for around 2 weeks with no issues)

happened to one of mine when i got it first, not sure what i did to fix it but i emptied loop, removed the the o ring gave it all wipe down and put it back together an its been fine since

Thanks, was it it just on the one speed it made the noise?I am going to rebuild my loop in a few weeks anyway so will give that ago. Will just leave it on 4 for now.

Mine makes most noise at speed 4. It was originally quiet when i first got it and it just started one day, just like yours.
