I'm having this weird noise when releasing brakes (not always)
sometimes after a speed bumps when I release my brakes it clunks.

I shared a video showing that It doesn't clunk on a bumps. (Sometimes it happens when releasing brakes after a speed bumps)

Already replaced Front and Rear Shock Absorbers/Suspensions and Leafsprings. Bushings, and any other suspension parts such as tie rod, rack end, stab link etc. are all Good. (already consult 4 mechanics about the issue but they can't find the source of the noise.
Brakes are all Good (Also checked by all mechanic, even ME)

It drives me crazy every time I hear the noise and I'm tired and wasted money for them to check but still no luck.

Check out your center bearing , universal and the gearbox and engine mounts

Assuming your 2017 is a 4X4 model you may be experiencing sticktion - "The static friction that needs to be overcome to enable relative motion of stationary objects in contact"

As Dave suggests look at centre bearing. Make sure your drive shaft centre and rear slip yoke is greased with Moly disulphide NGLI2 lithium grease. It needs this grease to overcome the sticktion problem which will sound like a thud . It is when you release brakes that the slip yoke needs to break stationary friction and release with a thud if the shaft has not been correctly lubed.

Have a read of the last post in this thread for procedure to lube slip yokes.

Go easy on tightening the zirk fittings back up - careful not to strip the thread

Sounds like the tailshaft clunk. check the link above

Hi. I only have 4x2 Hilux. Anyway, only the Universal Joints have fittings. Already tried inserting some grease (Moly NLGI2 Grease)
Still Clunks. I don’t know what to check next

Grease the slip yoke on the tailshaft.

This is what I have. How can I Grease it?

I note yours is 2wd, maybe different to the 4x4 but somewhere between the centre bearing and the diff there should (repeat should) be a slip joint to allow for rear axle movement. I can't see it on the diagram but it should be there. Maybe 2wd is done at the diff??

You can click the image. I don’t why its so large haha.
Anyway. Are you saying its the no. 6 (center yoke)?
It doesn’t have fittings. Please teach me how to grease that. The clunk is so annoying.

Thanks to all of you guys. I replaced 3 Universal joints. And It solved the issue. No one here in my place suggest anything to look at the propeller shaft.
