Id not like to drive this.

I'd want a replacement hub fitted.

The thought that might have been on the road like that is quite a scary one. Thankfully the owner has taken note and is replacing the hub. 

Just imagine if that repair was nothing to do with mot and that the car could have been put on the road for up to 12 months!

What sort of person carries out repairs knows the damage caused and then just puts the new track rod on and sends it out as OK

Many years ago I had a steering track rod that had been previously subjected to excessive heat at some time in the past, many years ago, and looking at the track rod possibly say years later the track rod did not look out of place, so on an mot you might not even pass and advise it never mind fail it. I sent the track rod back in the day to VOSA and they published it in the Matters of Testing. It was such a good example that until it had fractured you were none the wiser, VOSA didn't make a comment in their publication, but did advise that I worded the column very well.

Now that track rod fractured on me without warning at about 30 MPH, as I remember an HGV travelling towards me in the opposite direction, the track rod failed and the steering was none existent, it was very difficult to control the direction ability of the car and I was panicking trying to stop the car veering across the road, basically I sh**t myself and thought I was under the front of an HGV game over
