Knocking sound from what sounds like rear suspension
 

It's hard to describe the exact sound, but this is worrying me a bit. There is a knocking/clicking sound when going from a stop and accelerating. In first gear, I will accelerate, then lift my foot off the gas and it will make the noise again. It only does it at low speeds in first and second. The only suspension mod I have is RCE Yellows. Here is a video of the sound. This was filmed in an empty parking lot tonight.

Does it make the sound when push down on the rear of the car to rock it?

I tried this and it didn't make the sound. However, I bet I could push harder. I just was able to feel the fender flexing in and out and I'm scared to dent it haha.

is it like this. http://www.ft86club.com/forums/showthread.php?t=41762 ok just listened to it and it sounds just like that. I'm having the same issue. which is going to turn into this. http://www.ft86club.com/forums/showp...5&postcount=27

seems the axles are not holding up. shitty thing everyone of them has been denied warranty.

Fuck. Is this tightening of the nut something I can do without having to lift the car?

Yes doesn't mean it's going to work though. Didn't for me.

I always get that sound at rattle sound at 00:03-00:04 seconds at 1500-2000rpm. I would like to know what is it and is it damaging the engine. I've created a topic but got all sort of answers :S

Ive had this same clicking noise issue for like a couple months now. At first it was constant and loud and it eventually got quieter and happened less frequently. But it was my fault because i was drifting and snapchatting and swiped the rear left side on the curb. not too hard but enough to scare me. I took it to the dealership twice and they keep telling me its ok and stuff. Personally i dont think dealerships really care. Seems like my car just sits in the shop and then they bring it out after a couple hours sayin its all good.

Well, you don't need to put it on a hoist ...... but, I would suggest you jack it up to take the pressure off the axle ...... :)

This will sound stupid, and I didnt listen to the video or whatever, but check to make sure your seats are locked into place. Mine come out all the time and they make a clunky noise and you can feel it too

I would think we go to the same dealer but you are in Cali

Im also having the clicking sound problem coming out of the rear. I don't know is it the rear axles or not. This sound started to occur after the recent track day.

At first, I thought It was some loosen nuts, LSD, or sway bars knocking exhaust parts. All those things turned out to be fine after having mechanics to look up.
Please let me know if this is the sound indicating axle going bad or not ?

Thx guys

Have you managed to find out what's the source of the clicking noise? My car started developing similar noises after last track days. Got the car up and all seems fine...frustrated...
