Sloppy steering

[JamaicaJoe]

I think the front end components are under specified for these heavy vehicles. I had an 1993 E350 van and it was built like a tank. You could not break the running gear.

All good info guys, please keep it coming. This truck now has 12k miles on it. She drives 500+ miles per week. It has done this from new though. The truck has Hankook Dynapro AT2 P275/55R20 tires. Tire pressures are 47 lf 48 fr 46 lr 47 rr according to Ford Pass,

I’d also add that it depends what vehicle you are comparing it to. It does have very light steering, with little feedback. It ain’t no sports car, that’s for sure.

Ford’s recommended cold tire pressure for the 20” tires on your vehicle are 39 psi.

I think your on the too high end too much pressure for sure makes cars twitchy snd reduces contact patch. Haven’t tried high pressures in my expedition yet but past trucks drove horribly on high pressures

you are correct I just checked the door 39 is correct. I’m not sure why I put what I did. Actual is 40 all the way around, except for left rear is 46. She had a flat there a few weeks ago. I must have pumped that one to high.

I noticed if I had a 3-4lb difference between sides it did wander more to one side.
I think these big wheel/ sporty tire combos have more dramatic impact on handling when they aren’t right on the numbers. Vs my old truck on boring 17’s with thick rubber was far less finicky on pressures

Again, sport mode!

Check tire pressures cold in the morning before the sun hits the tires and heats them up with a digital gauge.
