No help but thanks anyways.

I looked up the 37” package that ford sells. Bigger tires, different wheels, 1/8” bigger shock shaft which means the 37 package comes with a shock that‘s closer to a real 3.0 shock. The one that comes on a normal raptor is more like a 2.5 shock internally than a real 3.0 shock.

So basically exactly what I have but my guess is they are only using the real 3.0 shock shaft but not the rest of the actual 3.0 internals.

No change in the CV joint or the axle shaft in the 37” package.

Tire size is unrelated to CV axle angle. Lifts increase CV axle operating angles as well as total axle travel. Higher operating angles place more stress on components, including the differential housing.

The Raptor 37” package ride height is only 12mm higher in front and 10mm in the rear than a standard Raptor, both of which are less than 1/2”. Overall suspension travel is decreased by 1” front and rear because of the larger tires.

The apparent misconception is that if the manufacturer offers a package like the 37” as an option, you should be able to add it as an aftermarket and still expect warranty coverage. That’s not how it works. Part of that $10,000 premium for the 37” package is allocated to cover warranty cost. If there’s an issue, the manufacturer is responsible to fix it because that’s how it was sold. What they’re not responsible for is to repair the consequences induced by the unknown variables of aftermarket modifications.

if anything the axle is higher up in the droop which is where most the travel is.

Heck yes, if the axle is farther off the ground then it must be closer to the truck, right?

You should stick to jumping dips on asphalt roads or actually think about what I wrote, maybe even scribble some pics for yourself to better understand.

The truck is lifted higher by a coil over shock creating angle. A 2” taller tire puts the hub 1” higher creating less angle.

For some crazy reason Ford still choose to cover it under warranty and for me that’s the biggest part.

I came here to look for answers but found none on actually fixing it only that I “lifted” my truck.

You guys act like the suspension on a raptor is made of glass and came off an f1 car and should never move more than a 1/4“

So to recap the diff case cracked because of high operating angles. That’s always the first thing to go, everyone knows those cases are nowhere near as tough as the parts inside.

Fortunately the guys at the race shop had some great insights for me and Ford required disassembly and crack checking.
I’m out.

OMG.

Suspension angles are unrelated to tire size. With the lift, the control arms angles are increased significantly, along with the CV axle angles.

The dealer decided to cover it, not Ford. I suspect possibly because they’ve tried 4 times to fix it in the past, and with the repeat repairs accumulating, they checked the axle housing and identified damage.

They told you that was the cause of the crack?

We probably should be careful with the term “lift”. The coilovers likely maintain a very similar range of travel. Meaning max up travel and max droop probably occur in very similar locations, what is likely different is the location of static ride height.

If I remember this thread correctly, the truck is running fox 3.0’s, not a spacer lift that shifts the travel range. Those type of “lifts” would likely over extend the axles, cause other issues, etc.

Go outside and let all the air out of your tire and tell me what happens to the a arm and axle angle. Now fill it back up and tell me what happens.
