Park your truck on flat ground. Measure from the ground to the bottom of the fender flare. Now jack up the truck in the front until the tires are just barely touching the ground. Measure from the ground to the bottom of the same fender flare. Compare the difference. 3” is a good number. Lower than that means you have coilovers with so much preload that you have taken away all your downtravel. Downtravel is important to having a stable and comfortable ride both on and off-road.
Im fairly certain those halos come with 700 lb springs which is a very heavy spring. I use 650 lb springs and I’ve got a heavy front bumper and winch. Reducing preload should solve your problem.
that sounds like a very smart idea. I would have never thought of that and will definitely do it. thanks!
Also, not sure if you adjusted them before installing or not but just remember if you do adjust them on the truck to jack the truck off the ground to remove the weight of the vehicle from the springs to make it easier to turn. I like to spray a little oil on the thread before turning the spanner nut to help it spin a little easier as well. Oh and make sure you put a rag or towel between the UCA and spring so the UCA doesn't mark up the coil spring.
Well I'm officially done with the install. Once I got it aligned the rubbing almost completely went away (slight rub when wheel is all the way turned in reverse, on a slope)
Steering has more play and I noticed some bump steer. Other than that I'm liking it.
Thanks for the advice and comments. I'm no mechanic but I enjoy doing my own work and learning along the way.
Now to address a turbo that decided now would be a good time to start leaking coolant. 🙄
Thanks! You know of anyone that has installed a steering stabilizer on a newer F-150? The steering is dramatically different. Not as responsive and the bumpsteer feels borderline unsafe on a rough road.
Do you know what your alignment specs are, that can be the cause. Keeping your caster set around *3.5 - *4.0 and total toe *20 - *30 helps a lot with stability and straight ahead tracking.
I know nothing about alignment so I'm not sure what any of that means. I do have the report. Let me know if you think it should be redone and what to tell the guys at the shop.
Your number's are actually ok, I mean you could go back and have them get the caster up into the *4 plus range and push the total toe closer to *30. That might just make it slightly better than what is. I've actually played with a lot of alignments over the years and with running bigger tires my f150's always handled better with a little more caster and toe. Right now my truck's caster is *3.6 and *4.0 and my total toe is *29 and handles great with 285/70/18 ridge grapplers.
