Apr 1979 to Nov 1999 -- Managed to sneak out to start my 1st civilian career despite a Stop Loss before the docs could board me and take timing out of my hands
I'd love to get $1.2 million for mine, but giving it away is a valid option.
I'm just outside the Brandon area so you're welcome to swing over and pick it up.
Yep, as Big Blue mentioned, both my rearched springs failed at flaws on the steel.
I'd had 3 inches or arch added then flipped the axle on top of them.. Initial result was lower than hoped followed with 1st the driver's failing on the road, then the passenger's failing while parked.
Perhaps...
I agree on both points. My wife's FX4 is (was) much less harsh in the front than my RWD and the 4" - 5" rake looks silly on anything but a funny car!!
The boingy bounce of the FX4 suspension over minor road imperfections is where I think Ford failed. The smooth road manners are impeccable.
My wife's FX4 rear springs have a different part number on them than my RWD, or the pair of 4WD rears I bought to re-arch for the RWD.
Her FX4 is a very early 2019, wonder if Ford standardized the rears later in the production run?
They are 14", 550 lbs/in coils, just a half inch or so longer than stock, but nearly 20% softer.
Not quite as low as I'd like. I'm out of adjustment for caster & camber, have some adjustable upper control arms to cure that issue.
And, I'm looking for shorter front struts. With the softer...
Not sure I agree with that. My DIY drop profoundly improved the front end.
Longer and softer front coils mounted lower on yellow Bilsteins.
Yea, drop spindles would be nice but there are other paths to the same goal.
I took the re-arch path. Had a local spring shop add 3" of arch then flipped the axle over the springs.
All good for a year then both springs broke at casting flaws within a month of each other.
2nd try was to use softer rear springs and air springs to lift the back end to my desired height...
2002 with DIY V8 swap. Honestly, a truck Ford should have built.
Used a crashed '96 Expo for the engine, trans, PCM and rear axle.
If not for the Torque Monster headers, would have made money on the swap and even if not, what I sold it for with 300K miles more than paid for the swap.
Found the same thing with my DIY Bilstien/Eibach fronts. Had to dial in .350" more on left side than right.
On install, I thought I might have mismeasured or possibly gotten an out of spec spring but nope, it's the same lean that Ford uses a spacer under the left rear spring to combat.
