Anybody else feel a reverberation in their suspension after going over bumps? What I mean by that is, after going over a bump in the road, it feels like the suspension bumps up and down repeatedly in smaller and smaller intensities until it finally settles back to normal. Like plucking a guitar string and watching the vibrations slow back down to a rest.

Of course it all happens very quickly-- the reverb goes away in less than second... I'm wondering if this is related to my shudder on take-off...

Yes, I do too. This truck's ride seems "bouncy" on the smaller bumps, compared to my '06. Suspension reverb is a good way to deecribe it, yes. It rides smooth, just not as planted feeling. I notice a lot of vibes too, compared to the old one.

Skandocious

Yep. Feels bouncy. I wonder what causes this...

Also, my truck is EcoBoost crew cab 6.5' bed, 4x4, 3.73, max trailer tow.

Edit: wrong thread.

You know, over city bumps and city street potholes, the truck almost has a jittery spring loaded effect. It's not unstable and feels planted, it just vibrates a little, almost like the truck is spring loaded right between the cab and bed. It must be a characteristic of the 150s frame and the way the bed hops. It's probably got nothing to do with the drivetrain. my dad's does this as well, it's a truck, that's what it does.

Skandocious

Yep. You've described my experience pretty well.

yep, seems normal to me. My chevy didn't do this, It may be something to do with weight and balance. Only thing i can think of is the bed vibrating. It doesn't do it when my quad's in the back, and the bakflip cover toned it down a bit.

I am leaning towards my tires contributing to some of the bouncy feeling. Mine has the michelin Ltx at2 265/70 17 tires. Also, these trucks have special hydraulic cab mounts, which dampen the jolts, which may explain the bouncy ride compared to my '06. I am adjusting to the electronic 6 speed as well, but I don't think it is necessarily a bad tranny, just different from what I am used to. What tires are you running?

Here's the way I look at it. The part of the truck between the cab and bed has got to be the weakest part, since there's no cab structure strengthening it, there's just the ladder frame. It's like connecting 2 bricks via a small thin piece of sheetmetal underneath. The bricks will flex independently in an up and down and twist motion since there's no upper reinforcement to support all that weight, and the same thing applies with a pickup. When you go over bumps the front end bumps and the rear end bumps, causing a flex in the middle from the transfer of energy from the bump, which probably results in the reverb. it's teenage logic from a kid that doesn't even take physics, bear with me here.

Now in 2009 when Ford added more weight, that flex in the middle got more dramatic since that part of the truck is trying to disperse more energy from more weight.

I have the same feeling too back ends skips over bumps all the time frost heaves are the worst
