I have a cinder block wall (CMU) that was built about 3 years ago. I purchased my home 1.5 years ago. I was told that the wall was built 3 years ago by the neighbor and it was built by a local handyman when the previous wooden fence fell over. The wall is about 20-24" tall, and spans about 50 feet across. On the other side of this wall is my backyard lot with clay soil. About 12 feet back from the wall sits a mature tree.
I did not notice the shifting of my CMU wall until this past month after some heavy rain storms hit our region, there may have been some minor cracking on the wall since we bought the home that was pointed out to me than by my neighbor but nothing that stuck out at me until this recent time.
So the wall is starting to crack and on one of the cracks it is leaning out where the top of the wall is about 3/4" out from the rest of the block wall.

So I took a look at the back behind the wall and tried to search for roots and did not come across any that seemed to be pushing up against the wall to cause it to shift. I than discovered from this same digging that the weep holes weren't properly constructed behind this concrete wall where there are no drainage rocks, it was just clay soil compacted up and backfilled right up against the concrete wall itself. I'm going to fix this part by adding some crushed rocks in but I wanted to know if there was anyway to reinforce this crack that is shifting before it gets any worst.
By relieving the weep holes with better drainage I'm hoping that I can release some of the built up pressure that was holding back all this wet soil, while its already dug up I wanted to see if there was any options in reinforcing the crack that is shifting. The wall hasn't leaned over too far out yet, but looks like if I don't stop it now from getting worst it'll tilt over one day under its own weight. From where it's leaning out it's also pulling a good 20-30 feet of over wall with it.
This is the part where I was thinking I can anchor a metal brace across it to hold it in place?
PS. I don't think there is any rebar in the building of this wall but I can't confirm this for certain.
