CV Joint Failure and Differential Failure

You can always upgrade the axles as well.

I did think about that. I saw that someone broke the DSS axles too in the same way as the factory ones. I figured they must be stronger, but still not built for that extreme angle. If my axles break again, I'll be upgrading.

So is it for sure the CV snapped and messed up the diff?
anybody know what a oem diff and axles would cost?

Well......pooooo.......no warranty coverage .....

Here is a good primer on CV joints.

One can see the potential "weakness" of this "link" in the drivetrain; however, I would think any type of CV joint should be able to hold together under a 1-2" drop (lowered & loaded car) from the differential to the wheel .....

(after all, that's their job ...... )

Weakness... link... The weak link

It's weird because speed academy hasn't had any CV issues on their Targa car, and they're on coilovers. My only guess is that the coilovers allow the axles to travel less and prevent it... Lowering springs, of course, will not do near as much.

Well, today marks my first week with the car, and now I have this ticking/clicking from the rear left as well. 12.4k miles. It's a '13 so still under warranty, gonna have to see what Toyota says on Monday..

Car hasn't seen a track or anything like it. Yes, spirited driving on the street has of course taken place, but not anything near what it shouldn't be able to handle.

As long as your tires look nice, there should be no issues for warranty. Many times they just call it a day after torquing the axle-nut though. For some, this helped. For others, the clicking returned and joints broke. Just be prepared for either situation, good luck!

First off, thanks for the info! Secondly, my axles are fine, it seems. I was convinced the sound was mechanical, or atleast coming from the axle, but I only heard to very shortly, because I was close to home when it happened, and when I heard it, I drove home and parked. Then two days later I decided to check how bad the noise was and when it happened (only turning left, only acceleration etc) - but when I then drove it, it sounded more like something was stuck in the tire, and indeed I had a rock lodged between the tire thread.

Now, it sounds silly, but it hasn't made a click since. But I can't shake the feeling how it did sound like a CV joint at first! I even had a full-time mechanic with in the car when the sound first occurred, and he agreed!

I had the TC and VSC off when I heard the noise though, and had them on again on the next drive, but that shouldn't matter right? All those do is act when the car is actually slipping/losing grip?

I do hope that it was indeed a rock! As long as it isn't doing anything anymore, I'd say don't worry about it unless any future noises come up. The electronic aids shouldn't make a difference, because I believe they are only wired to the brakes rather than the diff. If you had them off, then that's discards any thought that they had something to do with it. Yes, correct, they are reactive to slipping sensed by wheelspin. TC is made to prevent slippage in a straight line, VSC is made to keep the car from losing control in corners.

Oh yeah, I'm well aware of when they activate/what they prevent, what I meant was that they are purely electronical until they act, so to speak. It's not like it's mechanical and should make any difference if it's on and off, until they are supposed to kick in All they do is cut power and apply brakes.

Hey thats my video ha.

Also I had my axle replaced last year or the year before. Drivers rear was clicking. Was done under warranty.

Haha it's an enlightening video! Very good view of what's going on down there.

Daggum, I should have had it replaced when the clicking started before it broke. Oh well, I'm just glad it works properly for now!
