1996 Toyota Celica grinding from a stop

Yea just before u come to a complete stop is makes a definite click (single click) around the same time the trans would shift back into first

this may or may not be related: but there is also what woulds like a suspension crack from the front of the car when turning left, going over bumps, and sometimes even breaking

the cracking has always been there and never really caused an issue, this current issue on the other hand has gotten worse than before.

Update today: It seems multiple short trips make it more prone to happen. Could it be something to do with temperature change?
The sound itself also seems to happen between 1200-1500rpm

My brakes were inspected about a month ago. Recently I had the suspension noise checked and everything was tight, the clicking sound sounds alot like the sound you hear when the exhaust system is cooling down when you turn your car off.

I drove my car today on a long trip and no matter how hard I tries unless I gave it full gas from a stop I couldn't get it to make this grinding sound.

Best way to describe this sound is if you had flem in te back of your throat and u pushed your tongue near the top of ur mouth and breathed out thru ur mouth.

Also when your not in gear (its an auto) sitting n park if u give it a bit of gas u hear a clunk when you take your foot off the gas

This is to fix both issues?

Ive had an ameteur mehanic tell me the grinding is probably the torque converter

Some more addition info because he brought up the torque converter thing

If I rev the engine in Neutral there is no sound.

I did a test to check my torque converter suggested to me, and this caused a similar sound.

I held the brake with in gear and hit the throttle quickly (On/Off, I was scared to cause any dmg)

Should it make that grinding sound though?

So if I hold the brake and give it a bit of gas and it does that, that is a good indication I have a torque converter problem?

I have also begun to notice another sound that has developed in the past week or so,

another knock/cracking sort of sound that can happen whenever it wants to it seems, although turning right seems to make it happen alot more often than turning left. Going over uneven pavement is can also make this sound. Or even just taping the brakes and letting off them or rev'ing the engine in park

Front and Rear Motor Mount were replaced when the engine was rebuilt so they have 9,000K on them as well

Is there a proper way to have the converter tested?
If its bad, what sort of debt could I be looking at

Awesome, so I was convinced to buy a car because it had a brand new beating heart, but actualy its a ticking time bomb.

Well when I check my trans oil last time, it was still full and although getting to be that purplish/brown color it was still good, not burnt and certainly no metalic flakes

This would have been when I originally posted this issue, so less than a week ago when I really started to notice this issue. I do city driving but no more than 100 kilometers per week. Thankfully not alot of stop and go traffic
