CV Boot failing

[Szabo Mihaly]

There is no quality difference in the CV boots between a Raptor and a standard F-150, nor between F-150 and industry standards. Your vehicle was shipped from the US to Romania, there was plenty of opportunities for the CV boot to get damaged during transit, causing it to fail later. Road debris can also damage the boots, but it’s not common. It’s also possible you just got a defective one, which can happen on any mass produced vehicle. Only one other person in this thread had a leaking boot, which was fixed under warranty.

Yes, it is true is the same as f-150. I find out thid during my order. Also i was thinking about a small stone from the road, thats why i never think about bad quality. But now i see many have the same issues. Also the hole in the rubber is very small one. I study better because i have no warranty and need to fix myself. Over there i don't think someone is looking and searching what happened. Just changed. But this is a smallest think. My truck is running perfectly after 10.000 miles. Is just the morning fear on start up if is or not the cam phaser noise.

Before I owned the Raptor I had a 2017 f-150 STX that was leveled. If you’re saying it’s the same CV joints why didn’t those fail and every other F-150 that has been leveled? CV boots should not fail if you level your truck otherwise you’d see widespread issues.

Not the same axle, the same quality of axle. They have the pass the same quality standards. A leveling kit on an STX is no comparison to adding a 2.5" lift on a vehicle that already comes from the factory with increased ride height and CV angles. When you add that aftermarket lift you're assuming all risk, the OEM is not in the business of paying for damage caused by your untested modifications. Just because not every single lifted truck experiences an issue does not mean the issue is not related to the modification, the percentage of failures will vary depending on the lift height, installation, and operating conditions. Claiming 2 forum complaints on stock vehicles out of millions proves that that it's not the result of your modifications is ridiculous, especially when your truck alone has had multiple failures.

Curious on this one. Are you indicating that the control arm angle on a raptor, at static height, is greater with respect to the horizontal than a standard F150?

I would have assumed that any ride height increase, raptor vs standard F150, would have came from the longer LCA (hypotenuse) but at the same angle.


Edit: Do you know the factory CV angles for both trucks?

Since all of his suspension parts have been kept stock outside of his rims/tires, Ford wouldn’t deny any warranty work would they?

@zombiekiller 40s are cool and all, but your not Ken Block and Wetsen type of cool

Not gonna lie...
I wanna do this asap

I see tons of FWD lowered or not cars that tear through CV boots. Not once did I think Honda/Nissan/Mazda etc was making crappy CV boots/joints. When you lower or lift a vehicle, it puts more stress on the CV joint/boot period. Since it was warrantied I'm not sure what the complaint is. There are alot of F150's and Raptors around, just because we hear of a few on the forums doesn't mean a whole lot. I'm not surprised that Geiser said they never had an issue with CV boots. Why would they admit their product MIGHT cause issues.

I don’t remember complaining on here about it being warrantied. It was a question asking if anyone has had similar problems. Try again.

You could both be at least partially right.
How much is the height altered and how much change is introduced in that angling? It’s possible that the ‘lift’ isn’t immediately obvious to the naked eye and nobody’s caught it yet, or they did and dismissed it as causative or contributory. Maybe there actually were defects OR, a poor install of the prior (failed) boot?

If the lift is enough, I could see the joint generating more heat, fatiguing the boot faster Will it be enough to cause a quick failure? I don’t know, but with 2 failures in proximity, I’d be concerned:



This sounds procedural to me.

What do you mean by procedural?

I don't think you can say that without a huge asterisk. Ford attempts to match industry standard quality, if they actually did it, then you wouldn't see things like class action lawsuits. There was the myford touch 2.0 lawsuit, there's the 2.0 ecoboost lawsuit, and the fiesta transmission lawsuit. Ford isn't the most honest company when it comes to fessing up about cutting corners. Then there was the whole RS headgasket debacle. So let's not pretend that if ford had a bad batch of rubber on cv axle a that they'd come right out and admit it. If 99% of people that are running geiser and eibachs up front and only a few people are having issues, it's either the axle or the spring...but based on fords past I think it's really foolish to rule out ford completely. Fair enough?

Ford “fessed up” on all of those concerns and either issued a recall or extended warranty. They’re not KIA/Hyundai, Toyota, or Honda that cover up the defect and only do a recall when forced to by NHTSA. In fact, KIA/Hyundai was just fined $70 million by NHTSA for covering up defects related to their engine failures across multiple models. Don’t get me started on the Honda/Takata fiasco. OEMs all have product issues/defects, what matters is how they handle them.

If Ford had a “bad batch” of CV boots they’d issue a TSB or SSM. The fact of the matter is there is no “bad batch” nor are there widespread issues, even on the forums. If you lift your truck and your CV joint or boot fails, that’s on you. Same applies to any manufacturer.

Do you really believe there is no correlation between OP’s lift and both axle boots failing? Let’s not be ridiculous.

I'm with the Ford mothership on this one.

to the grumpy folks: If you're going to try to stick 2-3 hours of shop time and $64 in new cv boots on Ford, after you modified the vehicle, I've got some news for you...


you picked the wrong damn hobby.


and guess what? The replacement boots will wear in the same time-frame, if not less...


Then you'll be replacing them again.


And now you all see why lots of folks go 2wd with their built raptors.


IIRC the max CV angle is 28 degrees before the whole thing binds and breaks. Might want to go measure the angle. the closer you are, the faster the boot will wear.
