Hybrid / standard CV vs. Tremor CV -- comparison photos

[OneAlienBoi]

However, if I'm correct the actual splines on the ends of the shaft are the same. If that's the case then non Tremor owners worried about CV axle longevity can swap in the improved Tremor version.

Apparently we can't, at least not in the hybrids. I proposed this and that was what I was told at least.

Now im not guaranteeing same mpg as some of the lower mpg of the tremor may correlate to additional drivetrain friction of the beefier( mass) joints and lack of the needle bearings lighter resistance compared to the 10 large balls of friction with the cage .
However i would ponder to say its in the 1 mpg or less area.

Yeah, less. I did the math. A 1 mpg decrease would be the equivalent of heating your cv’s with a 750 watt heater. That would probably make them quite toasty.

I have standard axles on backorder for warrantee work. This is the second set which has gone bad. I'm going to see it they let me upgrade to the Tremor axles and still honor the warrantee. Stay tuned.

Unfortunately the Tremor axles will not fit on the Hybrid due to the Hybrid models having an completely different transmission to axle interface.

I'll be honest, if Ford put stronger CVs in the '25 mavericks, I'd be happy to meet them halfway if my original CVs ever went out under warranty. Instead of getting the CVs replaced for free by the same weaker CVs, if they did some sort of reduced cost program where you could either get the original, but weaker CVs for free, or get the new, and hopefully greatly improved CVs for a reasonable cost, I'd pay for the upgrade.

I believe some companies were considering making aftermarket maverick CVs some time ago, but I haven't heard anything since, but engineering, testing, and making new parts does take quite a bit of time. We'll see what they come up with.

Now it makes me wonder if the 25 Hybrid AWD 4k will have the beefier CV's. Those may be a direct swap for us with the standard 2K Hybrids.

We give Ford a lot of grief, some of it deserved, but they generally are better at setting right their mistakes than most car brands. Toyota is telling new Corolla owners to shove it after multiple brand new cars caught in fire, claiming it's the owners fault because they were exceeding 85 mph.

Whereas Ford once recalled my explorer to fix the roof rack clips. So they've recalled over much smaller issues than this.

Hybrids have a different length and different trans input . So Hybrids cant use the Tremor ones. The Ecoboost awd can use them.

Sounds like Ford to get the high MPG of the hybrid put a lot of work to get efficiency out of every part. Hybrid Needle bearings I am sure have lower friction and the 10 ball Tremor ones have more friction, but it makes since with the Tremor having the lowest MPG and the hybrid has the best. It looks like the hybrid cv joints are not weaker to save money but weaker to get better MPG.

This is awesome gentlemen! This site has the best people regarding resoures and solutions for our Mavericks!

It has been the wonderful folks here in Mavericktruckclub who were able to understand that our trucks needed AGM batteries, not flooded.

It has been the wonderful folks here in Mavericktruckclub who were able to understand that our CV axles are defective for the hybrid models, thus causing them to fail around 20,000-33,000 miles.

It has been the wonderful folks here in Mavericktruckclub who were able to understand that our trucks that already is searching for another source (better quality) CV axles. I think he may have found a source.

Thank you all for time to dive into these issues. If/when mine fail, at least I will be aware of what the problem is. And hopefully within the next year Ford will acknowledge that the CV axles are defective.

Maybe I am missing things, but I do not recall reading here that the CV joints on the EB failing with the level of regularity as the hybrid.

About 4 hybrid to 3 Eb when you factor in the EB crowd that upset the hybrid warranty clan by lifting theirs .
But I think overall its in the <1% area of actual affected fleet , honestly a lot less as we are approaching 100’s of thousands of each type on the road now.
It still could use the Tremor design on all models to eliminate the issue .
Just handing out info via pics , do what you want on your interpretation side of it though.

I think there's a lot more hybrid cv failures than ecoboost as well, not a 4 to 3 ratio as you suggested, but I think no one except Ford has the data. (And theirs isn't great for anything done out of warranty. It could have been done at home or by an independent garage.)

Thanks for the post and the pics. I looked at the originals on iCloud and Tremor CV design is vastly superior. I doubt that they'll adapt that style to the hybrid, but it's still useful for non-Tremor ecoboost owners, of which there are very many, to know they can and should use a Tremor CV when/if their stock units fail.

I keep saying Ford should address this now. It's gonna be a lot cheaper to recall and swap out the CVs on 300k trucks than it's gonna be if they wait and have to do it on 1.5 million trucks or something.

I knew I was special!!!

Checked with the dealer. They said they have to do exactly what Ford tells them for warrantee work. So I get a standard axle, unless Ford steps in.

If Ford is listening then there may be an opportunity to offer the upgraded axle on warrantee service. It may cut down on the repeat warrantee work for the same problem.

In case you are wondering, my truck is stock and unmodified hybrid 32k. The axles were replaced by the dealer last April under warrantee and I only drive on pavement.

Got one side replaced this week between 40 and 50K, other side once they get the part in. I drive on 'rough pavement' but by that I mean the pavement in areas around Ford HQ that are... not good to say the least.

My gut says that Ford is trying to hand-wave the problem, TBF it's more unsafe than the 'backup camera issue' (my tin-foil hat says Ford only did a recall because it was a safety feature/warranty issue). Gut also says that Ford is just plain happy that it's vaguely less catastrophic than the Fiesta/Focus powershift fiasco and they have lots of ways to evade responsibility. People with lift kits apparently have more problems, now that I understand needle bearings are involved, I get the why, OTOH...

Now im not guaranteeing same mpg as some of the lower mpg of the tremor may correlate to additional drivetrain friction of the beefier( mass) joints and lack of the needle bearings lighter resistance compared to the 10 large balls of friction with the cage .
However i would ponder to say its in the 1 mpg or less area.
But for a manufacturer who sells 100’s of thousands of units it makes sense to use it so more f150/250’s can be sold as cafe averages rise higher with the better mpg unit diluting the overall fleet sold average.

My experience with needle bearings are mostly on the bicycle side, but yes that difference is real and I'd agree it's probably worth somewhere between 0-1MPG (if not more for hybrids due to the additional intricacies of drivetrain losses.)

As to the second part of your reply that I quoted... Should we be asking bigger questions at this point? Namely, is Ford establishing a pattern of various 'loss leaders' that are likely to repeatedly break down in expensive ways in hopes of improving CAFE? As it stands their only defense is that so many of their vehicles have recurring issues...

I keep saying Ford should address this now. It's gonna be a lot cheaper to recall and swap out the CVs on 300k trucks than it's gonna be if they wait and have to do it on 1.5 million trucks or something.

My semi-cynical take is what I said above. They'd rather deal with the various legal actions later and try to minimize cost-per-financial-quarter.

We don't know mileage, or the cases of fleet vehicles where things may be handled backchannel or other ways (once worked at a place that got hundreds of Gen3 Rangers super-custom with at least a few special warranty arraangements.)

I'll say this, if Ford wasn't (playing?) clueless as to what is really going on, we wouldn't be seeing the level of backorder on the replacement parts we are... unless they really do have a proper 'fix'... yet I don't see how anyone can trust that would actually happen at this point. Personally, I'd expect that if MY2025 -was- fixed, we'd see a different part out there on warranty replacements by now... at this point I say that not just from a 'pragmatic' standpoint but also a 'legal liability' standpoint.

They're powershifting this problem lmao.

I am unsure of these bronco sport ones you have listed , that would require some one to purchase and compare.
The 2 i compared are a ford part numbered hybrid ( with different inner shaft ends) and a tremor)
Now comparing the actual joint construction of a standard with a tremor , the lengths and splines are the same .
And the joint construction ( 3 way divot style slider ) are same between a hybrid and standard ecoboost front.
The beauty part is we are talking oem tremors are $405 for the front pair out the door at your dealer .
Maybe $160-180 more than oem standard ecoboost axles.
Now they still all have cheap grease and plastic style cheap boots on them still .
So have to keep an eye on them .
I am searching for a better boot solution and would recommend the good belray grease for repacking.

For the standard ecoboost , it appears so .

Have you or anyone else installing the beefier Tremor CV axles on an AWD EB?

LONG STORY LOL: I dropped my Mav off last February for an 80k "the works" service and tire rotation (which they didn't do on top off not completing other included fluid flushes) and told them I was hearing some grinding when the wheels are turned to the right and accelerating from a stop. I asked them if they could check the drivetrain and suspension to see if anything needed to be fixed, which when picked up they claimed they didn't find anything wrong.

Fast forward to a few weeks ago I called because the noise was getting more frequent and a loud pop had started since the service on the left side when stopping and going (wheels straight) which I suspected either the driver side strut was going bad or a motor mount. When I made the appt to drop off the following Monday I notified them that I was a few miles from hitting 100k and would be over by about 600 miles when I drop off, which the scheduler said it shouldn't be a problem to just mention all this to the tech advisor at Sheehy Ford. Well you can guess how that went and Ford Customer Service wouldn't even help, because in February the advisor hand wrote in to look into the issue...

Sure enough when I called later that day I was told I need to replace both front CV axles, funny how under warranty they couldn't replicate this but 657 miles over they immediately found what was wrong right? I was told when I got there and questioned about the different noise on the driver side (loud pop) that the tech stated the motor mounts may need to be replaced as well and that he took them apart and inspected but couldn't find anything wrong so he reinstalled them. Well no more loud pop on driver side.

I then figured I'd see how bad this shop is, so I told the advisor that I thought the grinding noise was either a transmission or transfer case issue...he then suddenly agreed and said that his "MASTER TECH" also recommended maybe replacing the transfer case and scheduling a drop off to inspect the transmission on top of the CV axles AND all motor mounts being replaced. I said wow and he added that they really aren't sure what is causing the grinding noise when wheels are turned to the right and I accelerate and that it could be a multitude of things. When I mentioned that it seems like the CV axles failing is a common issue with Mavs he said that out of all the Mavs they've sold he hasn't had any CV axle replacements....

Please tell me them Tremor CV axles will work with my 22 XLT FX4 w/4K lol

I had a spare set here that i offered up to anyone in san diego area to help put in to solidify my measurements .
No takers , so thats the ones i debooted for the pics . They are off to an aftermarket shop to see if i can get an improved tremor axle ( usual polishing of cage or swapped for cromoly or 300m parts and better aftermarket boots and grease )I would say yes all day , just order both sets for the replacements and full comparison on your old take outs will tell and send the unused pair back .
About $260 for oem EB stock ones a pair
About $405 for oem Tremor stock ones a pair.
Aftermarket shop should install for around $700-800
