Advice? Increasingly louder knocking noise!

Hi all,

Hit my first problem that I'm actually stumped about. I've had my car (Fabia PD100 Comfort) for a few months now, and done all sorts to it:

• Changed all brakes and pads
• Changed rear shock absorbers
• Changed front springs, shocks, mounts, the lot (drivers spring gave in)
• Fixed wiring problems on AC to provide ice cold air
• Changed CV Joint boot (The passenger side new shock didn't tighten up properly, we think that the bolt tightened up on rust and that meant the shock wasn't properly held in place and could fall down and balance on the driveshaft boot.)
• Oil and filter change (just over the 10,000 mile mark)

In that order. The latter, CV Joint boot and oil changes were done this Sunday. Yesterday the car drove fine but this morning came the massive problems. Whilst driving across town I heard the car was making extremely bad knocking noises repeatedly (when you know its related to the wheels) from the passenger side. If it was in gear and no throttle/braking, it would knock and be faster/slower respective on the speed I was driving. If it was coasting in neutral, no knocking. With throttle or any reasonable amount of braking, it stops again.

I continued driving it carefully to do important tasks but it has got worse to the point it is scary to drive, if I didn't have to do these tasks I wouldn't have driven it but they were important.

The car is now parked on my mother's drive awaiting my father to look at it and i'm borrowing the Merc. Anybody know what this could be?

Thank you to anyone who can help, this car is my pride and joy.
