Do you have the awd Merkur? Those can be fun with the Turbo on them.

You might have just bent the steering shaft. Since the steering system isn't tucked up like it is on a Independent Front End, a good shot into a stump can bend things up pretty good. Or being winched back off of a stump after your spotter thought you could clear it. Lucky for me he had a spare...

I would take a look at the bars in front of your front axel and see if it has a suspicious bow to it before checking to see if your steering box skipped a couple of teeth.
