Hey guys,
2004 FX4 here with about 185k on the clock. About 4 or 5 months old to me, so I'm still figuring things out
At highway speeds, the truck drives like an older truck. Rough, harsh, loud, and the whole body vibrates as I drive along.
I've replaced tie rod ends (and got it aligned after), all four shocks, front sway bar end links, front wheel hubs, 3x driveshaft ujoints.
What else could I replace that would help with road vibrations?
I'm converting this into a camper, so I'll be doing many highway miles, so I want this thing to drive like its brand new from 2004.

 

It may be time for new wheel bearings at all four corners. Also, replace the body mounts.

 

Have you had the wheels balanced?

Also might try loading it with weight close to the weight you figure the camper will be to see if that helps or makes it worse,

 

I thought about having my wheels balanced, since theyre from the Previous Owner, but wasn't sure if it would make much of a difference. Thanks, I'll bump it up the priority list.
Body mounts are a good idea too, thanks! I'll take a look at the rear wheel bearings. The fronts were very obviously bad, they wobbled pretty horribly when holding the wheel at 12 and 6 o'clock and shaking before I replaced them.
I already have most of it built, so I'm currently pretty close to my final weight, haven't noticed much difference in road noise.

 

May be a matter of tire having a flat spot , or all of them.
My 92 has that problem. Maybe PO let it sit in 1 spot for quite a while, as is my case when I acquired it.
They may look good, had a new tire with unbalanceable situation.
My 2 cents. Ken

 

Great, thanks Ken, I'll definitely get my wheels balanced before my next trip
