Nope, and you need to flat bed it. I jacked it up, verified the CV was broken, verified it wasn't going to make a mess and called a truck.

If they reach the limit of their movement by the angle, under load, than something is going to break. Reaching the limit of extension or compression could also rip the clip off or crack the body.
At the limit for angle the shaft can touch the outer edge of the body and crack it, also the cage can crack and break at extreme angles under load. Both would give the clicking sound.

I'm not sure what sort of CV's are fitted to the inner but if the shaft is breaking inside the boot it could be where it's been touching the body at extreme angles?

I have only heard of 1 person breaking the shaft. They were on slicks at a drag strip, and with fair power to boot so that is acceptable.

The cage on my CV broke down the middle (in the same place as another members). I will post pictures later. They are all breaking in the point between the bearings. If my tulip is still around ill verify if there are any impact marks on the inside of the base of the tulip where the shaft might impact.

Most of us have... Some of us have done it multiple times. I just bought DSS axles to resolve the issue.

The axles are weak. People who are extremely low have more issues than others cause the angle of the axles get more and more jacked up as you lower it. I would lower mine a little more but don't want to risk breaking an axle.

Waiting for subframe and diff risers to become available. Also gonna make an upgrade to DSS axles down the road

Yeah I was hoping diff risers but I would rather buy new axles than raise my car up. Ill live with my childish wasys.

Exactly. Post up your issues if you would. I would love to see a nice roster and see realistically how many people are doing what, at what height, with what power.

@feldy thanks for the video! I was planning on recording some once I get my car running again as well.

The risers don't raise the whole car up. It raises the subframe and diff up allowing the axles to not be at such extreme angles which helps take added stress off. It also gives more under clearance.

Here is video from today. FRS suspension shots. Racecomp RCE springs and Koni Yellow inserts.

Interesting angle to view the car from. Also looks like you got a cone stuck in there :P.

Thanks. I will be interested in any pics and any sign of impact.
For the cage to break at that point suggests extreme angles because it carries zero loading normally. It's just there to keep the balls in position.
Could you check it for indents where it broke, from the balls and scuffing on the outside faces? The indents should be minimal, quite tiny at low mileage. If it's wearing there it will weaken it and wear there would likely be from not enough grease at the factory or not up to spec?

I used to have a business selling, fitting and repairing cv joints, so i'm interested from that angle.

Yes I will take detailed photos as long as Toyota didn't dump the axles. They wanted to see the axles so I dropped the car off a few days ago but the tulip should see be in the diff. When. I swing by wed I wil take some detailed photos. I will also strap down some go pros to my car to get footage of the angle where I broke it before I re-adjust my suspension to help out. I just immediately upgraded the axles as I feel there may be a problem with th OEM setup that just makes it a weak mechanical point compared to other cars. I have driven a number of my previous vehicles on the same road in the same condition without issues. Hopefilly if get enough info we can find the thresholds.

Picture of my left axle faillure on the drag strip.

The first observation is that the inner race shows the shaft was extended in the normal operating position, causing the inner joint to run extended with nowhere to go with further extension.
Either the car was lowered making the shaft run at an angle and pulling it out from the centre position or if it was horizontal the shaft is too short by perhaps 20mm?

I've been having the clicking for a few thousand miles now and it's becoming more and more profound to the point where my girlfriend is even saying "WTF was that? What did you break now?"

I'm really not wanting to go to the dealer since every time I go for any little complaint/concern they dismiss it or they just throw the "If it ain't broke, don't fix it" line at me. None of my local dealers have much experience with this car so any work that has to get done takes forever. I can't afford to be out of a car because of techs who don't know the car so I'm stuck between waiting it out until they break or until there's a TSB out for it (unlikely).

Any documents or tech notes that anyone can share from their experience of having their axles replaces? I'd like to replace them myself with a heftier set but unfortunately don't have that kind of money to just put down right now. Anything that'd help my case would be great.

When does it click?

Thanks for the video... I've completely understand now. I'll change my axle and put the car for storage this winter. At spring, I'll raise it.

[husker741]

Here's my thread I started awhile back. There's a video of the clicking sound.

http://www.ft86club.com/forums/showthread.php?t=43936

Never tracked. On RCE Yellows.

I started hearing creaking when I entered/exited the car. Then after my 1300 mile road trip to Florida, I heard it every time I accelerate. It has gradually gotten worse.

Unfortunately toyobaru doesn't sell parts to rebuild (well they sell almost parts but it costs almost as much as the entier axle). And the performance axles cost barely more than the stock ones. Stock are 340-440ea depending on where you shop.

I was referring to the guy with the flatbed quote. No need to waste that much time and money. DSS axles are a good solution FTW

Damn, that really shows precisely how soft the diff and subframe bushings are. Good thing there are upgrades!
