2025 AWD Hybrid CV joints failing?

[LoboMike]

PS are the Mavericks with bad axles mainly FWD or AWD, or does it make a difference? Putting 240 hp through 2 axles (FWD) is different from putting it through 4 axles (AWD)

Mavericks are not full time AWD so 90%+ its FWD

XJ Jeep Cherokees had live axles, it's a completely different setup. You can lift those as much as you want you might get driveshaft issues but never CV joint issues because the axles always stay in line with the center of the wheels ...

XJ cherokees never have cv joint issues…..
Correct.

However, the Dana 30 front end in the XJ was well known to be the weak link in its power train and they blew out plenty of u-joints and ate plenty of ring gears, especially in the low pinion models.

Depending on how the initial suspension geometry is set up will determine what you can and cannot do with a lift.

Until you compare stock geometry you cannot throw out the CJ as a comparison.

Well, I wouldn't throw out the CJ anyway as that is a body-on-frame. Nor would I even compare the XJ Cherokee (which is unibody), I was just addressing the notion that because the Mav is unibody it will have CV failures if lifted. Unibody vehicles can handle small lifts. The Subaru community has been lifting unibodies for awhile. I am on the Bronco Sport forum, and I do not see all of these CV axle complaints on their lifts (also mostly in the 1.5-2" range).

I am not saying it is ideal to lift a unibody and going above 2" is probably not something I would do. I am saying that the relatively small lifts we are discussing should work but for the crap components that Ford installed on the 22-24s. I know that there will always be the "never mod anything" crowd, and anytime you do a mod there is always some risk. In this case, I feel that the mod that is being done is so mild that the risk should be pretty negligible. That it hasn't been the case seem more of a component failure and the high rate of failure on unmodified vehicles seems to prove that. If Ford has improved the quality of the CV axle for 2025, then a 1.5" lift shouldn't be cause for automatic failure IMHO.

Has anyone found the part numbers of the cv axles for the various models to see if there are different parts for the Tremor, Lobo, and standard models to know if there are differences or is it just speculation that there are different axles for different models?

Maybe I'm not understanding your post correctly but the fact that the Cherokee and the Maverick are both unibody doesn't have anything to do with it.

The Maverick has independent suspension with differentials that are bolted to the frame and axles with CV joints to send power to the wheels.

The Cherokee has live axles, its differentials are inside the axle housings and move with the wheels. The Cherokee doesn't have any CV joints, it has solid axles. It's a completely different system and it's impossible for it to have CV joint problems because there are none

I was commenting a post originally that said the Mav shouldn't be lifted because it is unibody. That is the only thing I am commenting on. Other aspects of the design of the Maverick are not discussed or mentioned in my post. I stand by the notion that with proper components a unibody vehicle can be lifted a small amount like 1.5-2". In fact, Ford even is marketing a lift kit on the Bronco Sport (only a 1" lift). Hard to state that Ford unibodies can't be lifted when Ford itself markets (and warranties) a FP lift kit for a unibody.

As far everybody pointing out the differences between Mavs, XJs, Subarus, etc - I am not arguing that point. I am just pointing out that the mere fact that the Mav is unibody does not mean it can't be lifted at all. There may be design issues with the Mavs that will limit this, but it is not of itself because it is a unibody vehicle. I still don't understand how the Bronco Sport has many lift kit options, is very similar to the Maverick and there is virtually no complaint of CV issues.

I just pray a “Monster truck” Maverick just might bring peace between us all… bolted frame to the underneath, you know the kind of Maverick I can take my 8yr old son to at a stadium nearby…

Simple humans love soundbite answers, which are inevitably only partially true, or only true in specific cases.

CV joints angle changes as you turn corners left or right, they can operate within a range of angles & you can raise or lower within some range of angle, otherwise the Maverick CVs would be destroyed when taking a sharp turns.

The actual question should be, "how much can I lift or lower for city driving vs taking sharp corners at high speeds on rough potholed trails".

Generally what Ive heard, 1 to 1.25 inches raised or lowered is not going to make CV joints wear out any faster for the same kind of driving, if all the other components, seems like )for FWD based cv joints at least) its 1.75 inches & past where tradeoffs are made breakage becomes more probable.

Now I got myself wondering what sorcery Subaru uses with their lifted fwd-based cv joint rally cars where the epidemic of failed cv joints isn't happening - do the constantly blowing out head gaskets on Subraru boxer engines do something for their long travel CV joints?

So are you saying that the Lobo, which comes factory lowered, has different CV axles or more likely there is some tolerance to geometry change?

Oh man, Subaru owners are coming for you with pitchforks! My friend of nearly 50 years always wanted a Subaru and after helping him buy a Silverado 4x4 truck, he came into some money and bought a used older Forester maybe a 2012, instead of paying off the truck that I cosigned for, as agreed. He bought some new furniture and took a fishing excursion honeymoon in FL with his mail order Philippine bride with the remainder. True story!

I'm building a home and took an unwanted credit score hit since he didn't refinance the truck. Karma is a bitch though and the Subaru engine went kaput immediately with no warranty. It's been in some fleabag mechanic's yard for about six months now. I wonder if that rebuilt pile of junk will ever see a road again? It's true what they say: A fool and his money are soon parted.

I'll let you know if my Rough Country 2.5" Lift destroys my CV joints. The lift is necessary for my land ingress and egress.

That may be true for highway driving - but for city driving it’s probably 90% AWD?

These part numbers are for the 2 front axles. The rear ones are different as well.

Front axles for Tremor
PZ6Z-3B436-A
PZ6Z-3B437-A

Front axles for AWD and FX4
NZ6Z-3B436-B
NZ6Z-3B437-A

Front axles for FWD
NZ6Z-3B436-A
NZ6Z-3B437-A

The FWD and AWD have the same part number for the left axle.
All Tremor axles are unique to the Tremor.

Rear axles Tremor
PZ6Z-4K138-A
PZ6Z-4K139-A

Rear axles AWD & FX4
NZ6Z-4K138-A
NZ6Z-4K139-A

The hybrid has its own part numbers. New model ver.

SZ6Z-3B436-E
SZ6Z-3B437-C

Bronco sport has part numbers unique to it and are not shared with the Maverick.

Tremor axles are different internally and are a much better design. I can't remember if it was BWicka (RIP) or another member who - showed the differences between the design and confirmed that Tremor axles are direct fits for non-Tremor EBs.

No way 90%. A little more than on the highway since there's more stop and go, but the rear still cuts out once you're moving, even on really slippery surfaces like ice. You can watch it on the dash screen.
