I have a non lifted ford hybrid and both CV axles are bad, 32k and have to wait weeks for replacement. Anyone replace with a non OEM axle that is heavier duty. I take it really easy on my truck, but do tow from time to time and I am nearly to 2k limit, but it shouldn't fail and it is a known problem and there has been a software update, but that was done on mine and both still failed.
Sounds like the issue I’m having. Can you identify which axle the wobble is coming from? Mine is coming from the front driver’s side. I’ve had it looked at by ford twice and each time they said it was the lift causing the angle of the CV to be more extreme (which it is). The increased angle is then binding the CV at some points (turning and accelerating at low speed). I have no issues at higher speeds. I was like “if this is the case, why isn’t it happening with the other axles?” They didn’t have a good answer. There is movement where the inner cv enters the transmission, which I think is the root of the issue (I think I have video of this somewhere back in the thread), with more movement on the driver’s side than the passenger side. When I explained this to Ford they said it was normal movement in terms of the additional play on the driver’s side compared to the passenger side. The service manager actually showed me this on a brand new Bronco sport (same platform as the Mav), and I felt the same movement that I was experiencing. Could be a bigger recall issue that has yet to be discovered. If I figure out a fix I’ll post in this thread. As of right now I’m not overly concerned as it is only happening at low speed.
Why? One of my life's lessons I have learned in my 74 years on this planet, is to either do not give dealers reason to weasel out of a warranty, or, say to hell with it and accept the fact that the mod you have to have could impact things down the road and are good with that. (Like Lift Kits)
Correct!
Yes, they are, and that does give me pause, but, from somewhat following this issue with the EB's, it does seem to be much less of an issue as it is with the hybrids. So that is a good things for us EB drivers. I would be interested if this is a first year issue with the EB's and that maybe it is somewhat resolved with the '23's & '24's? I dunno.
From what I see at stock ride height the CV angle is about fifteen degrees. That's on the upper end of acceptable for a stock half shaft joint. I'm assuming a lowered Mav would bring this angle down to under ten degrees which is much better for it. The more angle that a CV joint has the more energy is converted to heat and the more susceptible it is to oscillation
Like I mentioned, the two electric motors in the hybrid powertrain generate peak torque at zero rpms and instantaneously, that's most likely what's causing the higher failure rate in hybrids. I've also gone through a set of halfshafts replaced under warranty on a stock suspension Maverick
The Tremor doesn't even have a 1" lift conventionally speaking. A quarter of that added ride height comes from the standard taller tires (235/65R17) which has zero bearing on CV angle. The actual suspension lift is about 3/4 of an inch.
Ford says that the Tremor halfshafts are stronger than the AWD ones.
