Here are the symptoms : clunks + “riding over bumps” feeling during slow turns while applying power, If not power is applied of if I press the clutch to turn sound is very minimal.
Please ignore the missing trim, It will be installed soon.
Any help will be much appreciated

Thank you everyone !

 

First source to check.....rear UCA and LCA pillow *****. They should be tight.

 

Thanks I will put the car in stands probably friday. and take the rear wheels off to see.
Any test you recomend me to do? thanks

Look for missing or loose PPF or dif hanger boltnuts.

What is the mileage? My similar clunk probably was due to very high mileage driveshafts (the ones to the rear wheels) or dif.

Clunk finally went away when I replaced both with newer.

So I don't know for sure.

 

hi, thanks, just so i undertans, you place the mounts and hardware, but not the actual PPF or dif, right? by the driveshafts to the rear whell you mean the cv axles?

Thanks

 

Mazda callls them driveshafts and the main driveshaft, they call the propeller shaft.

I replaced the dif and the ring gear assembly. This may have included new spacer shims.

I replaced what you call the cv axles.

When first got the car I had similar clunking which I could not trace. Someone suggested spraying liquid wrench on the pillow *****, which seemed to help for a good while.

I slowly replaced all bushings and pillow ***** with new, or used ones in better shape.

It is an exercise as expensive as replacing an engine.

 

FWIW I have replaced the PPF x2 after cracking them. Both broken PPF resulted in a significant 'buzzing' sound as a hint it was trash.

Added a diff brace and it has kept my PPF intact.

 

o wow, so after replacing diff and and shaft the clonk was still there? the car has 70k miles, I will lift the car today and look, probably check the pillow bushings and spry some silicon lubricant to see if that changes the noise at all.

 

As others have mentioned the pillow ***** and control arm bushings are also more likely the source. Which I also have replaced.

And no longer have any clinking/clocking/buzzing or banging.

 

I replaced my trailing arms and pillow ***** with an known brand aftermarket alternative, and its pillow ***** starting clicking immediately.

 

o wow, so after replacing diff and and shaft the clonk was still there?

No the clunk was gone, but I don't know exactly which action fixed it.

 

Normally I would say it's probably the pillowballs, diff mount, or a driveshaft u-joint.
But since this looks like a stripped out JDM track car (one of us, one of us!), it's possible that you have an aftermarket LSD that's making (at least some of) the noise.
Do the tires chip a bit when turning really tightly?

Lift the car up and see if both of the rear wheels spin the same direction.

The fact that your hatch is stripped out means that every little noise your rear end makes is going to be amplified.
