Is that coming from the diff? It doesn't sound like it. Does it speed up the faster you go?

Looks like it makes the tick every one revolution of the driveshaft. Is it hitting anything down stream?

benzc316

Yes it speed up when i go faster

Ill check if the drive shaft touch something

Jasonoff

Did you torque the shaft coupling bolts in the proper sequence? They could be flexing as well. I'd try loosening and re-torquing in the proper sequence.

Ididnt install it myself

But 2 weeks ago they also install ltheader xpipe and midsection
Maybe there is something touching the driveshqft
Ill take a closer look at this

I had to edit your link to get it to work for me.

If exhaust work was done check to make sure the pipes are not hitting the cross brace in front of the resonator. I doesn't really sound like the case but just to be sure. That doesn't sound like the differential to me but rather like the driveshaft is hitting some thing as it turns. GL figuring it out.

You sometimes need shims to align it. I'm betting yours may not be installed correctly.

Jasonoff

I would think if there was bad gear mesh between the pinion and ring gear it would either whine or clunk at a higher frequency.

Not make a sound once per revolution like it's doing.

Mazspeed

Could be. I don't know what sounds it's making. Could be the wrong fluid, bad gear mesh spacing, not enough or too many shims. But it should be silent.
I would stop driving it and take it to a good shop ASAP before it becomes a potential driveline disaster.

Mazspeed

Ok, just saw the link and clicked it. That sounds very "tinny". Like it's hitting a piece of tin on the revolution. I see some shielding in there, but it doesn't look like it's hitting it from that angle.

Thanks for you help
Car is going to the garage tomorrow
Will have a better view on the lift

Sound like the shaft is hitting the heatshield
And i hope so lol
