Bouncy ride on freeway

[Michael McNeese]

Good day folks I hope all is well, I am questioning a bounce that happens when I am driving on the freeway. I have a 14 F350 crew that has a 8 foot bed, when I am driving on the freeway there is at times a serious bounce that seems to be coming from the rear. I have bran new tires on the truck and have had them balanced, is this something normal that happens or should I expect a smoother ride?? I am wondering if the road conditions are part of the problem, initially my thoughts are how can a truck this big and heavy feel so volunerable on the road, any insight would be great. Thanks and have a great day...

Does it have stock shocks?

Also.. The bounce could be your wheelbase, versus the 8, 10 or 12 foot seams between the concrete freeway slabs. Longer wheel base vehicles can tend to start to Purpose (bounce) as they traverse those certain lengths of slabs.

Does speeding up, or slowing down effect the bounce ??

(We've got a 7 mile stretch of Freeway 'round here that feels like yer ride'n a Buck'n Bronco.. in my LWB F-350. 50mph.. or 70 will smooth it out (kinda).. speed limit is 65)

I have a short bed F 250 that never bounces on the highway. I also have a 2011 F350 4x4 FX4 package longbed that bucks like a bronco on certain parts of the highways that are slabbed concrete. 75 mph cures it.

back in the day...ford added a damper to the rear frame to help offset these bouncy events.
they put it on my 06 crew cab 2wd dually....as part of a recall thing of sorts
not sure how much it helped.
biggest helper was when i was running empty, i would drop rear tire pressures to 20 - 35 pounds until it had a flat tread contact patch. made a world of difference.

Had this added to my 06 and can't tell that it helps all that much. We have some of those
concrete roads here in AR. and they will beat you up in a long wheel base truck. Next time
try moving over into the left lane and see if that helps any. It does here on some roads.

Sometimes a few hundred lbs in box helps too
