Shimano Tourney to Shimano Deore XT?
I've been reading old threads and it seems I can replace the Tourney rear derailleur on my 2017 Trek Marlin 5 29er with 3X7 drivetrain with the 9 speed Deore XT.
I have dropped the chain on the Tourney several times already. I like the bike and only need a bit better shifting and less chain drop. I don't need a better suspension for my riding. I was hoping the stronger spring would help my issues and at about $70 seemed a good place to start. If this won't work or help my issues, please advise.
This is the rear derailleur I am considering. Will it be a drop in upgrade?

If it was my bike, the first thing that I would do would be to have the derailleur hanger alignment checked. Whenever I've encountered a bicycle with rear shifting that didn't respond to normal cable tension tweaking, derailleur hanger alignment has usually been the culprit.
If hanger alignment turns out to be the problem, you're done and you've saved yourself $67.00. If the hanger alignment turns out to be okay, at least it's a common issue that you've ruled out.

10-4 on that. I'm not sure that the derailure isn't out of spec itself. One hinge point seems wobbly compared to an old Acera I have. I'll replace the hanger but thought why not go with the best rear derailleur I can get if this stuff works like I think it does? Great ,ultra reliable shifting is all I really need in the way of upgrades. I could get a new Tourney and try it but the extra isn't much if the Deore XT will work a lot better. I wouldn't drop several hundred in upgrades to this bike but I got it used for $200 and I don't really need anything else for a while.

IF your chain is sized too long, it'll have less tension.
Shift to BIG:BIG and do the test in the pic.
IF you have more than 2 link SETS, your chain can be shortened.
A Tourney RDER & 7 speed "should" be nearly bullet proof until it wears out.
A RDER for a 9 speed is going to have a narrower cage and be a bit more finicky with the wider 7 speed chain.
I wouldn't "upgrade" beyond an 8 speed RDER for a 7 speed bike.

Perhaps you should check your limit screw adjustments, after you check the derailleur hanger as suggested previously. As mentioned Tourney derailleurs are pretty robust.

It's "possible".
I'd just buy a new Altus myself.

Older Acera and newer Acera have different speeds over the years.
You "might" have the same problem as a newer Deore.

+1 on the Altus.
I had the Tourney rear derailleur on my 1 year old bike replaced after clumsy me stepped on it after dropping the bike. I must say, It worked fine untill then.
The bike shop replaced it with an Altus model. It works flawlessly and is clearly higher quality then the Tourney it replaced. I'm surprised Shimano would make such an outstanding product for a budget price. You could spend 2 -3x more on other Rd's and do no better overall.
To be fair though, The derailleur is just one component for shifting, And probably not even the most important. The condition and quality of the cassette (which happens to be Shimano too) might be as important as the derailleur. Shifters and cables are also an important part of the package. As I said, This bike is only 1 year old with about 1,400 km on it, So it should come as no surprise that both the Tourney and Altus derailleurs worked well.

I can't tell that the Tourney is damaged or just not as well built. I can't tell on the hanger but the kid that owned it before me bent the rear rim and looks like he did it quickly after he bought it and didn't ride it any more. I trued the wheel and the derailleur works basically. but I have dropped the chain on bumps already and it has up shifted on me during a super hard push before.
I figured I would just replace the hanger and derailleur to make sure and wanted the best one I could get. Cables and everything else looks new.

This is not the first thread that you posted about upgrading this bike’s shifting. At this point, I’m going to say go ahead and do it. Because you’re not going to be happy until you do. We’ve all told you all the adjustments and repairs that you can do. They will all have to be done on the new one, too. Get one that says 9 speed and has a barrel adjuster at the cable stop, some of them don’t.

Actually I was only trying for a definitive answer.

I put all XT 10sp on my old crappy Trek and couldn't be happier. It was about 5 years ago now and it still rides like it is new, with fast, one finger shifts up and down the entire cassette. This replaced old 7sp LX I believe that worked but not nearly as well. To go with 10sp though I needed shifters, brake levers, new 10sp wheel, cassette and chain. It was the entire system not just the derailleur as 10sp Dynasys is a different beast than 9sp. I also put XT v-brakes on since I needed separate levers anyway. But, having said that, it is a slippery slope in that one change leads to another then another. All told, that part of the upgrade was $330 which included a 10sp wheel. The other part of the upgrade was the front dynamo wheel and that was another 130 plus 110 for the light itself. So I'm almost $600 in on an old bike.
So while I've done it, I also could afford it. If buying a $70 derailleur is a stretch for you don't do it.

There isn't a definitive answer, because sometimes you just have to try something and see how it plays out.
You can get the same added spring tension from any Shimano Shadow derailleur, and the Deore level will save you some coin:

Also helpful is to avoid back-pedaling in rough terrain. And possibly it can help to minimize chain slack by shifting into largest sprockets before a bouncy descent.
A more sure solution is to upgrade to 1x10 with a clutch derailleur and a chain guide, but that's an expensive can of worms that has you essentially replacing your entire drive train. Two of my friends have done that though -- going from 1x9 to 1x10 mainly for the option of a clutch derailleur.
