Default Knocking/Crunching noise on reversing at an angle

For the last 1 week or so, I have been noticing that when I reverse my car (A 4 + year old opel corsa) out of my parking slot in the morning (with the steering turned about 60% of full turn), I get this weird knocking sound (once in a full wheel turn) from the front left wheel and the car takes a mild jerk as if it rode over some small stone

There are absolutely no issues while driving forward or reversing straight
I'll be taking it to the service station this weekend but I hardly have any faith in GM service so was hoping the experts could throw some light upon it

The front left axle/ bearing needs repair/ replacement.

It used to a common problem in maruti earlier.

Found a matching query here (Noise from the AXLE)

Are you sure you arn't killing something(dogs,cats, your jealous neighbour's ego etc):-D......just kidding bro!!

well i had a similar issue with my brother's Astra and turned out to be the right front axle and the noise was only at a certain angle(in my case full lock) but was easily rectified at GM service center. Dont remember the cost though as my bro got it fixed.

i guess it just needed adjustment not a replacement but the mechanic said it an initial sigh of axle wear and would require a replacement in the future depending upon driving style

LOL
Guess what it turned out to be...a loose mudflap on the left wheel
While going forward and turning, the loose flap would just lightly brush against the turned wheel thus not making any noticeable noise
but while going back, the flap would brush inwards causing that sound

Now I undesrtand why the

I am so relieved that I'll just splurge the 15K mental expense I had set aside for this repair job

All it takes is that extra bit of effort to find out the root cause.
I am glad you dint head over to the service station , else am pretty sure they would have managed to get your cars axle changed.
