Toreadorranger Build...2 years in the making

[Toreadorranger]

You could always get a pre 78' F150 D44, narrow it or run some more backspacing. My fullwidth diff on 17x9 runs 1" wider per side then the EB axle on 15x10's and gets you hi pinion. You could also search for some Supercab F150 knuckles as they are flat top and you can run all ford outers.

The chevy knuckles are thicker where the studs are machined. which is why I used them. They are also more common then the supercab knuckles.

The low pinion actually helps out with my build as Im trying to keep it low so the LP helps me do that.

This is the only benefit that I see, and I sometimes wish I went LP for that reason. I tried to stay low on 35's. I'm sitting at ~3.5" of compression. It's definitely as low as I'd want to go with the spring rate I'm running.

Sorry, meant that more for the other guys asking. I know you know what your gettin into, just lettin others known there are some options.

The build's looking good!

More people out there with LP axles than HP. In some places its easier to order a set of bolt-on portals than find a HP axle.

I'm use to seein duece and a 1/2's and 5tons on tractor tires. I forget about HP and LP axles haha.

And more stripped out LP teeth than high pinion. Its just too bad everybody but ford poorly-engineered/penny pinched into putting LP front differentials in their product.

Id Take a HP frontend and have 3" more lift for clearance than have a low pinion axle.

Sometimes you have to take the axle you have, and I have no problem with that, but when people start touting the LP axle as being as good as the HP, Thats when people need to take some engineering classes. The LP gearset is significantly weaker than the HP gearset, Period.

Until you decide to back up, usually out of a crappy situation putting more load on the front end. Its a 50/50 and both have their benefits.

LP gearset isnt as weak as you think. I wont argue that it is weaker, because by design in the front it is weaker. I recommend going over to pirate and finding the LP vs HP thread. Theres alot of talk about it. And alot of people saying my brothers wifes dog breaks LP gearsets like its their job. Yet in the end there was less then a handfull of people who have actually had proof of broken LP 44/60 gearsets. And Im a Mechanical engineer so

This really doesnt matter though since the gearset isnt the weak link. 99% of the time you will pop shafts and joints way before you break a gearset.

Ive had two LP D44 gearsets in my hands out of chevy front ends that had intact shafts, with stripped ring gear teeth, One was a 5.14:1 gear set, the other was a 4.10:1 gearset, One was out of a 3/4 ton frontend, the other a half-ton. I purchased both front ends for their flat top knuckles and got a killer deal on both because they had blown out gears.

And as long as were having the WhipOut contest, I may not have a piece of paper with my name on it that says Im an engineer, but I do have practical expirience and rational thought (With a bit of mechanical engineering schooling). Mechanically, the LP front end is at a serious disadvantage (in the forward direction) because it pulls the preload off of the inner pinion bearing (not because it puts pressure on the coast side of the gear teeth as many would lead you to believe). When you pull preload off of the inner bearing, the pinion deflects causing less tooth face contact and shearing of the teeth. Now as said above, yes the LP does have an advantage in the reverse direction, however, 90% of obstacles are approached in the forward direction, especially the ones which put enough stress on the front axle to shear ring gear teeth.

Now I dont need the same WebJockies over at ButtPirape4x4.com to explain to me that a D60 LP front from a chevy is stronger simply because it was put on a truck with a bowtie on the grille. Its simple physics, under a 4x4 that spends the vast majority of its action in the forward direction, a High Pinion front axle is significantly stronger than a low pinion front end.

If you seriously defend the other position, you dont deserve your degree, period.

I'm goin to get my boots, Anybody need a pair? *hits gettin deep round here!!

argueing over LP and HP. Reminds me of pirate

Where did I say a LP was stronger? No where. I just said the strength difference is not as large as you think it is. With out any knowledge of the setups those axles were run under you have no facts. Ive personally broken a stock HP D30 gear set on a stock cherokee. What does that say? Nothing, it says we abused the shit out of the jeep and it ended up breaking. With the amount of LP axles out in the "field" and the amount of RP breakages that actually happen there isnt enough data to support a 40% strength difference. People would be poping gearsets right and left way before stock shafts at that percentage.

Let's get this build back on topic shall we......what's next on the todo list?

 

[Sasquatch_Ryda]

Wow....sorry I mentioned my preference in front differentials

As you were...

Im holding you personally responsible.

Let's get this build back on topic shall we......what's next on the todo list?

I need to replace the driverside motor mount with my new ruffstuff mount. I need to cut my upper link to length based on my mock up and tack the upper link mounts into the truck.
