Strange rear end 'click'?
 

So I notice an odd click/clink from the left rear wheel today(exactly like hot metal cooling down after you shut off the car). It seems to only happen when under load, even at the very slightest. I jacked the rear end up, and with the help of my wife, turned the wheels and everything was smooth. However, when taking off, in 1st or even reverse it will generally occur. It's not a guarantee though, sometimes I don't hear anything, and it's not like a consistent patterned noise, like a rock in the tire. It's totally random.

My first thought was diff, but it drives butter smooth, no weird popping, or grinding at all. I have read some threads about a similar noise, and the culprit being loose axle nuts. So I took the wheel off, and re-torqued it. It barely moved, so I doubt that's it. I'm thinking CV joint, but I can't imagine how?

I AM running OFT, with an e85 tune, but surely that's not enough power increase to be popping CV joints? I'm not lowered, and no wheel spacers, or aftermarket wheels. It's basically an all stock car. No drag racing, or auto cross either, but I do drive it like a sports car, with the occasional spirited country sprint, and sometimes sliding the rear end around a bit. I'm at a loss..

How long have you been driving it? I remember the first time my wife and I went out joyriding and we both heard this - http://www.ft86club.com/forums/showthread.php?t=13451

We were so concerned at the time, I pulled over and searched all around both rear wheel wells.

Nah, it's not the rear deck. I do have that sound though, albeit very faint so I havent messed with it. This is 100% in the left rear wheel well area. I have around 4500mi on it at this point. Just returned from a 750mi trip if that matters any.

Thanks for the suggestion!

I have it. No idea what it is though. Only seems to happen when starting from a stop, and what I perceive to be the left side, because that is where I am sitting. My list of potentials are:

U-joint
Axles


Visual inspection looks fine on everything. No negative effects thus far, and I've probably had it for ~4000 miles. I chalked it up to "because race car"

Lol yeah maybe it's been there for a while I've just not noticed it. Hmm. Really curious though, I will say something about my next dealer visit I guess.

@edeekeos you have said it's not the rear deck but sometimes these noises aren't that directional.

Here's a fix I came up with that fixed all the noises I was getting from the rear of my car. Only takes 30s so worth a try and even if it doesn't fix the loud noise might fix the feint one you have

This definitely is not the rear deck.

If all you've done to the car is an OFT running an E85 tune, I'd run the E85 out and fill up with gas. Flash to a gasoline map (or stock if you are concerned with them flashing over your tune) and heading to the dealership and letting them diagnose/fix it. You have a warranty for a reason, use it.

I have this noise as well, it comes from the rear left side of the car. I can even hear it sometimes when just getting in and out of the car with the car turned off. I have no power mods, just some wheels and tires.

My old car used to make clicking sounds from the rear, maybe the wheels or brakes rotors, no one ever really nailed it down, but I would try torquing your wheel lugs, or even swapping rear wheels side to side.

Just removing and reinstalling the wheels got rid of the clicking on my old car.

Mine just started doing this last night.
I saw another thread on here where the OP posted a video of him running next to the car and the left rear was clicking away.

In that thread they explained that it is the rear axles and they need to be retorqued.
I think I'll just take it to the dealer and ask them to retorque

Yeah, I tried retorquing the axle nut, to no avail. Also, for whats it's worth, I just went and did the rear deck popping fix. Original high piched pop still persists. I will be taking it to the dealer this coming weekend, and see what they think.

Looking forward to hearing how it works out. Best wishes.

I think what they mean is behind the wheel where the U-joints (CVs) bolt to the wheel hub.

The u joint is on the driveshaft, not on the axles.

Those are constant-velocity u-joints.

There are 4 CV joints on these cars. One at each end of each rear drive axles.
In the manual they are referred to as "EDJ"s or EBJ (extensible ball joint :iono:)

In the manual I dont see any bolts on the axles to torque though.

No.

I understand what you're trying to say, but a Universal joint and a Constant Velocity joint are not the same.

I just ignore it. :p

Just turn the radio up, or run a loud exhaust.

I also experience this clicking sound. Its usually when I pull out of my driveway. I too am running e85 and other car mods but I have been hearing this click ever since i was bone stock. Maybe its normal?! haha idk

If the bolts holding the rear axle bearing housing to the rear axle carrier were loose that would be some seriously dangerous mojo.

Besides the axle nut, those are the only other axle-related fasteners I see potentially needing to be torqued.

But there's no actual torque being applied to that joint. Just a cantilevered load.

Well I feel a little dirty. I was just trolling to back up Stu. "Bazinga," I guess.

I took the wheel off again, and re-torqued the 4 'axle bearing housing' bolts, as I only did the axle nut the first time. While down there I re-torqued ALL the suspension bolts as well. Still no change. At this point in time, I am ~%95 sure its the cage in the CV joint. Is it feasible/safe to pull the boot, and check this without pulling the axle?

Probably suffered the same fate as this one..

Rear brake adjusters for parking brake maybe??? I had a Chevy Impala that did that...

How would I check this?

I dont know why this picture made my day....

Re-doing the axle nut did not fix mine. They had to replace the entire thing. Its the metal getting cracked in the cv joint.

I do what I can.

Does it sound like this? My dealer can't figure it out after leaving the car with them all day.

Mine is at the dealers right now for that very noise.

I swore it was a CV joint, so they replaced the whole drvs side axle.
They just called and said the noise did not go away.

So they are going to replace the wheel bearing next.

Here is my noise (sorry vid taken in the dark):
[ame]http://youtu.be/Yn8y8lnsHWA[/ame]

So what was it? Mine is getting worse (clicks more often). Now sometimes it'll click twice in rapid succession.

Btw your video is private so we can't see it.

I had the click in my left rear (for quite some time). It sounded just like the OPs video. It didn't get worse or better.

Recently I had some ARP extended studs installed. The mechanic had to remove the rear hubs. Install complete and now the clicking is totally gone. It's bee a couple of weeks now and the click has not returned. My guess, summin' is loose back der.

They replaced the whole drv side half-shaft that comes with both CV ends.
The noise didnt go away so they replaced the wheel bearing.

Then the noise sounded better to them so they declared it fixed.
On the test drive, I told them they fixed the drv side, but now I could hear the pass side.

So they probably got rid of the noise on the drv side with the half shaft, and they were then hearing the pass side. So they changed the bearing when they didnt need to.

Now the pass side does it and it is getting worse, so I'll just wait until it's about to fall off before I take it back again.

I am convinced it is the CV joint.
Try the video again (it's just audio)

Mine makes the same noise as in the video. The head mechanic at the dealership I currently have my car at swears its a normal noise from the drive shaft, but that doesn't explain why it only started making the noise 2 weeks ago after 18 months of ownership.

Mine does that. I can get multiple clicks in a row. Can always hear it when pulling out of the garage or if I'm on the gas and release, it will click.
