Another Broken Axle / CV Joint

[rrknapp]

This sounds backwards. Dropping the front diff and installing a taller knuckle will maintain cv angle will it not? How will your driveline angle not be changed by lifting?

This is an H2/Duramax/Allision conversion. (not that it matters, I'm just proud of the beast. I know, it's too heavy and bulky for trails) with Rancho 4" true suspension lift. The spacers marked in red are necessary to maintain angles, With Spacer on top of coil, you are sitting on top of factory suspension, everything

below is in the same position. Think of it as a body lift, but this is easier since there are only 4 lift points.

Yup. Tons of people that wanted to either save money by not buying Sasquatch or that were too impatient to wait in line for it, but wanted the look. Going out and immediately spending $3k-4k on new tires, rims, and a crappy spacer lift kit doesn't make it a Sas. Lots of broken M190 front axles coming.

The "Lift Me Baby" reference under the wheel wells wasn't in reference to a $50 Rough Country lift or perch collars. It was referring to Fox/King/Billstien coil overs and corrected control arm geometry....aka a proper lift that would cost more than getting Sas Package in the first place.

And maybe a diff drop...ford left enough room for me to squeeze mine 1.5” lower. Makes a BIG difference. At my near stock ride height my CVS are nearly horizontal

I’m not sure I’m buying this story. You felt you needed 4WD on a gravel parking pad but you’re a “very seasoned 4WD guy”?

33 come on the stock axle setup you are fine.

I don't think I have seen anything larger than the BD 32s offered. What comes stock with 33s? (Ranger Tremor and FX$ also only come with 32s). My Badlands has 33's stock, but also has the 210 axle (Dana 44 equivalent). Same story with Jeep from what I remember. It has been gone over a lot, just because a 33" tire "fits" doesn't mean it won't have some compromises, including durability. I had an 06 LJ, super simple, professional 2" lift and 33" KO3s. By 60K the steering and knuckles were toast. Adding a lift just multiplies the weakness. All that being said, this situation could be as simple as a bad half shaft from the factory.

I'm sorry but saying a crappy 2" spacer puck lift doesn't affect CV geometry is comical.

Not aimed at OP, but in general Ford should include this in the glove box.

SAS is a crazy bargain.

Jeep guys has been asking for 35s and lockers for decades and the Bronco has them on EVERY trim and folks are still debating whether or not to get it?

The real question is why the Bronco axle/half shaft is $1100 and the Ranger is $300? You played, now you get to pay. No warranty for you.

Sounds like you have a uphill battle ahead of you. Situations like this is where the Magnuson-Moss Act comes into play. But unfortunately not in your favor in this situation.

Honestly not picking a fight here. But, a "proper lift" like a "Fox/King/Billstien coil over" looks no different to the CV angle than a "$50 Rough Country lift" or a stack of washers for that matter. The lifts you recommend will increase the CV angle - Period.

Lowering the differential can help control the CV angle on these lifts, but is also controversial in this community.

A spring preload can limit the amount of droop, at the expense of limiting travel, but this is no different than putting on a strap to limit the droop on a spacer lift. These will both limit the maximum droop, which will limit the maximum CV angle, but the CV angle is still increased at all times due to the lift imparted.

Control arm geometry does not impact the CV angle either. And, it is well documented that the stock upper control arm is quite capable of handling a 2 inch lift (with corresponding adjustment of the LCA).

No lift is more "proper". There is just the understanding and expectation of the end user.

Have to agree with this. While my past experiences in track racing a daily driver says the MMWA will do a lot of heavy lifting for the customer, It's a pretty clear direct correlation between the lift and geometry of components.

That the dealership was so quick to state this (via the limited and likely less-than-impartial information provided in the OP), does indicate they have dealt with lifted trucks and broken components in the past.

There's a reason the Ford Performance Racing catalog parts are desirable even if they don't go to the extent and capabilities of the dedicated aftermarket parts suppliers. But they did engineer it to work in that very specific vehicle and back the product with a warranty.

There are very few counter-arguments to this.

One of them happens to be the 2-door Badlands with 2.3/MT. The only component differences between that specific build and a Sasquatch (assuming MT is a mandatory item and you recognize the 2.7 is nonsensical when crawler gear exists) are:

• Wheels that still need $900 worth of actual bead-lock rings to function as intended
• Wider plastic fender flares
• 35" tires which you will absolutely want to be replacing with something better anyway
• 0.25" front suspension lift
• $2,300 additional MSRP

So in the one specific case above, I would argue that the Sasquatch is about a ~$5K waste of money and time. For drastically less than that you could have a proper set of wheels and tires, then address the control arm issues and have a better rig for less than what is offered with Sas.

But yea, in all other builds, Sasquatch is a meaty product that gets all the guys hot and bothered to jump on with aplomb.

As all of you know, there are many ways to make a vehicle taller. Bigger Tires, Body Lift, Coil-over spacer, the deluxe, most expensive is to drop the driveline. This method changes the CV angle and needs correction. For all but the driveline drop, CV and steering link angles will be exactly the same at the new ride height. That said, at full drop on a trail, the tire will drop 2" further and will change the angle. (assuming nothing else is limiting the drop, such as stops on the upper control arm, as is the case with GM 3/4 ton)

Coil over spacers absolutely will change the angle of the axles....
