Should I change my wheels ?

Hard to tell from the angle of the video, but make sure the top wheels are tightened as well. Make sure they are sitting on the frame groove correctly...I did a direct drive mod and had this problem. Retightening the belt helped too. Just a thought

The top wheels are tightened but I'm not sure what you mean by sitting on the frame groove (sorry, english is not my first language). I'll try tightening the belt a bit later. Hopefully that'll help :-)

Well, I just checked and noticed my gantry was slightly bent. I also noticed that the wobble was more important with one of the two upper wheel so I guess that might be the issue ...

So those wheels are called v-slot wheels, they are chamfered to match the chamfers of the 8020 metal piece (part of your gantry) that they glide across. If for some reason of the wheels is slightly crooked, it won't sit/roll right. Somewhat similar to a train and it's railroad tracks. If those wheels aren't on the track just right itll fly off....hope it helps!

I recently noticed that I had visible lines on my prints. After inspection, I noticed some wobble on my printhead and tried to tighten the eccentric nut but that's as tight as I can get. To add context, I've had my ender 5 for 2 years and never changed the wheels (or the belt). Do you guys think that changing my wheels would fix it ?

Can you upload a photo of your wheels? It'll help to diagnose if they are worn out our if something else is wrong.

Sure !

What makes me doubt is that I don't feel any bumps so if it were to come from worn out wheels, that would have meant that it would have been pretty uniform which seems unlikely to me ...

Yeah, that's what I thought too at first but everything is tight :-/

Bottom wheel has an off center nut thingy that is used for tightening, did you try that as well?
EDIT: Step 9 and 10 here shows you where it is located https://cdn.shopify.com/s/files/1/1210/0176/files/Micro_Swiss_Direct_Drive_Extruder_Installation_Instructions.pdf?v=1592671102

Yes, the video is taken fromwhen the eccentric nut is at the point where I have as little wobble as possible.

If you need new wheels they are as cheap as chips, make sure to replace the x and y axis as they see the same usage, the z axis will likely never need replacing as they move so little

Did you tighten the eccentric nut on the bottom wheel?

What wheels do people recommend as replacements?

Time to upgrade to linear rails ;)

Have you done the upgrade ? I'm getting closer and closer to not have anything stock on my ender 5 x)

I just did an overhaul to my 5 plus which included a linear rail conversion. I believe the parts I used would carry over to the 5, think you would just need shorter rails. Took inspiration from this post https://www.reddit.com/r/ender5plus/comments/p0xv89/cosmic_ender_5_plus_linear_rail_eva_conversion/.
Klipper + these mods and its a completely different printer!

I already thought of trying klipper and just noticed that my gantry was bent so that might be the occasion ... Thx for the idea !

No problem, happy modding

If it is affecting your prints then yes replace them or at least buy them for the day they do need replacing

Since you seem to have already checked the eccentric nut, I'd say just buy a pack of new hardware from Amazon or wherever. I did that myself the other day. Like $12 for a bunch of wheels and the rest of the hardware. Admittedly, I am a big fan of collecting spare and replacement parts because everything seems to somehow break on my printer.
Sure, I can do that. I just wanted to check first if I was not missing something :-)
