So about two weeks ago I noticed that when I drive 0-30 km/h and I go over bumps, I hear this weird knocking sound. I feel nothing in the steering.

over 30, I don't hear it at all and once I drive over 110 km/h, that knocking / thumping sound is continuous. As soon as I drive under 110, it goes away.

It makes the same type of sound a bad tie rod would make (I had my right tie rod and wheel bearing replaced back in November).

However, never did it make that sound when driving over 110 km/h.

Could it possible be my left tie rod?? What else would cause a knocking sound at low speeds and that same sound, continuous, over 110??

Any help would be greatly appreciated!!

It usually doesn't cost a dime to have it diagnosed at a tire store.
I live in Montreal, Quebec, Canada and I have yet found a garage that doesn't charge to diagnose car issues...

Everybody charges something...cheapest would be Canadian Tire at 30$, it is free only if I decide to do the repairs there... :((

My local chain tire store bends over backwards to get my business. Maybe I'm spoiled.
Went to my mechanic and he lifted my car up. There was 3 mechanics pushing, pulling, hitting all kinds of parts to see whats loose and what could possibly be causing that weird thumping sound.

They came to the conclusion it is my from right lower ball joint. It's loose.

The mechanic said that since there is play and the wheel does wiggle a bit, that is most probably what causes that thumping sound going over 110 km/h and at low speeds.

Does that make sense??

Yea it sounds right to me. I had a bad ball joint and it would bump and knock at pretty much any speed. You just had to listen for it. You can test this yourself. If you can jack up the whole front end of the car so both front wheels are off the ground, and just grab the wheel and wiggle it. If there is any wiggle or play at all, then something needs replacing. If you look behind the wheel you can see the ball joint moving if that is indeed bad.
