Default Clunking sound from right front *update*

I replaced the TRE's, that wasn't the problem although the right side was a little loose.

I also checked the brakes and all hardware around the suspension and subframe, all tight.

One thing I discovered is that I can make the noise happen by bouncing the car on the right front. Almost sounds like the strut is loose or banging around. I have H&R Coilovers, been installed since the car was new, so about 70k miles.

The noise is horrible, when I hit a small bump it sounds like the wheel is falling off!

I searched the archives and there seem to be many causes of this noise, none of which are my issue.

I'm about ready to bring it to a shop, any last things to look at before?

The nut that holds the top of the shock into the mounting plate can loosen and make that sound.

Default What's the torque spec for that nut. Mines making some clunking noises too.

I noticed that when I go over speed bumps and jack up the car it clunks.

Default I had a similar problem in my old A4...

Turns out that whoever did my suspension install didn't put in a little washer that sits ontop of the strut rod (I guess) between it and the strut mount. So, basicall where the strut rod ends and the threads begin there is a little lip and this washers goes ontop and then the strut mount. Not having the washer wore the mount and it was loose even though the strut was torqued down.

Boom, there you go... maybe?

Default good n tight!

If you're asking about the nut that threads onto the piston...about 35-40 ft lbs should be fine. It's tough to get a reasonable amount of torque on it if you don't have the right tools. Usually getting 30 ft lbs on it is a challenge...so "good n tight" pretty much implies, put as much force as you can on it.

Default Re:The two 13mm nuts under the access plugs?

I checked mine and they are tight.

Default No, those do very little and are only torque to ~12 ft lbs...

Odds are (based on your description) it has to do with the shock. Pull the shock out, and check the nut on the top of the piston. If it's loose (compress the spring and then attempt to torque it down), that's your problem, and if it isn't loose, it's probably a dead shock. In the case of the later, you want to remove the spring, and push pull the piston to see if there is any resistance left.

~40 ft-lbs. Tough to do with the strange bolt, impact wrench set low may do it to.
