CV Axle snapped @ 8k miles

Rear end grenades, weak leaf packs, timing chain covers. What I remember anyways.

 

Thought that looked familiar.

What dealer?

 

The picture on post 1 clearly shows OP's CV was a tulip joint.

This matches the parts diagram, but not Tinkerers video. My guess is the parts listing will be updated with the other CV axle at some point in the future. I bet a dealer could look it up currently and see the two separate part numbers.

 

What I get in a somewhat painful 16 page read is this is a modified suspension TRD Sport that also has different drivetrain parts than a similarly priced TRD OR has. That makes it really easy to understand risk and a problem from being outside of specifications plus an authorized dealer knowing a warranty claim likely denied.

I'm not purposely abusive or an off road hobbyist but from MTB and ski trail crew I'm off road fairly often, have to turn in tight quarters and not having any problems.

Something forever in my mind with seeing the mods many do is why they did not get a TRD OR in the first place. With 50 years experience with 4x4s, farm, construction, river guide & trail plus ski area work over and over and over again locker or posi axle has saved the moment or day before wheel and tire or other modifications people do. My '99 4Runner with GU package was equivalent to TRD OR now and I never modified more than a switch to stock size AT tires. Multiple times when I was guiding or ski area crew it saved or went by people who had non-locker axles but other modifications. I know I hit my bad habit of a tangent here but from experience, it seems like a lot are very likely going for some sort of look more than function.

Good luck to the OP here but I'm firmly in the camp of not modifying anything that would risk a warranty claim.

 

I'm not ordering anything.....they do. They just refuse to communicate, and when I give them feedback on the job...I get..."oh, that's not possible.....that's not the way it works on on the print". Well it obviously doesn't work in reality either, soooo.....

Example, new water feed pump for a cooling system. One of them comes out, get the numbers off the pump...and then I remove it so they can measure the flange and pattern.

New pump comes in, one inch too short, ten bolt holes instead of eight. When I point that out...."Oh, just make it work, we spent a fortune on those pumps".

Need to learn something..

 

Update, (Faulty installation)

Many posts had mentioned the differential drop, which was installed, but it was not installed properly. FML
I went into the Toyota service center to get additional pictures knowing the truck was being worked on. The service technician informed me differential drop only had one of the two bolts installed and showed there were no indications of any hardware installed; which was the primary of the incident. As of now, the truck is being repaired, under the insurance claim.
I have spoken with the install shop and informed them I will be looking for a resolution on their end. They have requested the Toyota repair and findings report and intend to inform management.
I intend to reach out to ICON and request to have the suspension installation inspected by an alternate shop, or ICON directly I live less than a hundred miles away from ICON HQ.

 

Insurance will cover the repairs it sounds like and you might be getting a check from the install shop as well. It may not all turn out bad in the end. Swap your cv’s out for the offroad or pro cvs if you can. I know alot of the newer landcruisers that want to wheel, are swapping their cv’s out with the “good” tacoma cv’s

 

For those who haven't been following along closely, these are the brackets in question:

 

Thanks for the update. Now all of the 4th gen trolls can suck it.

 

I fully expect all of the mouth breathers to stand by their previous statements by making up some other thing to complain about.

 

Just have to circle back here to this one. I'm sure a reasonable reply is going to come.

 

Good luck with that.

 

So if the diff drop wasn't bolted up correctly does that mean the diff was just free floating, and that allowed the separation? Just trying to picture it and might need to crawl under my truck.

 

There was only one of the two bolts installed, my turning while backing released the diff drop from its intended position; and is the cause of the failure. (to the best of my knowledge at this point)

 

It's not that all engineers are inept, it's just that some of your firm's engineers are inept.

The moral of the story of this thread, after 16 pages, is that some mechanics are inept per OP's last post.

 

@pinem56 are those Icon’s extended travel?


Edit:
Whoops I tagged the wrong person. Question was meant for the OP

@BoBsworld21

 

I apologise for not making my original comment more clear. After the 3rd gen Tacoma came out, many on this site spent the next 8 years bitching about how the 3rd gen was a turd that ruined the Tacoma name. Now that the 4th gen is out, it appears that the target of the hate has now moved there. I wasn't around when the 2nd gen came out, and I was wondering if the 2nd gen was subject to the same scrutiny.

 

I work at a municipal transportation agency, and I do product engineering for my side business.

At work, we have 2 types of engineers:
Those who routinely work with their hands and also value feedback,
And those who are younger, don't care to work with their hands or value feedback. And, they are usually ideologues who won't listen to blue collar workers with experience.

I suspect it's the same for Toyota and other manufacturers, but add a 3rd issue: financial constraints.

I rarely meet "stupid" engineers.

 

This right here. Spent many years cleaning up Engineering mistakes as there was no experience based on actual operations.
