Front end wobble after hitting a bump

I have a 2005 Daymon Day break. the Chassis is a 2004 F53.
I have new sway bar bushing in the rear (front ones looked recently replaced) I did do the Cheep Handling Fix on the front end. all tires are in excellent condition, and have proper air pressure.

On two different times taking the RV out imedialty after hitting a bump on the passenger side front wheel I felt a very substantial wobble in both the front tires, and the steering wheel. when it happens, it almost feels like the camper is un controllable, I hit the brakes and after slowing down it goes away. the first time I thought I blew a front tire, but after checking there was no tire issues, and I proceeded on without any other issues. the second time it happened only about 5 minutes from the house, and I continued on without issues to our camp spot about an hour away.
I have already changed the sway bar bushing in the rear end, and even though the fronts look newer, I have ordered new fronts as well. when they come in I will replace them too.
I understand that the bushings are most likely not the issue, but changing them cant hurt.


I believe the issue is with the steering stabilizer/damper, but I`m looking to see if anyone else has had this issue, before I just start throwing parts at it.

the unit does also seem to have a fair amount of wander when I drive, but that also could be because I've only driven a Class A 4 times, and need to get used to it.


Thanks for any help.

    Suspect items are ball joints.. Tie rod ends and drag link ends. And basically every joint in the front end.

    Find a Truck size alignment shop and take lots of bank account with you.

    Just to clear things up: The F53 chassis uses KINGPINs and does NOT have any balljoints. The F53 has a solid front axle and leaf springs.
    Balljoints are used with independent front suspension and coil springs. Much different than what's under the F53.

    If anyone is interested in having your tires balanced by the best machine made, look up a location that uses the Hunter GSP9700 "Vibration Control System". It measures "Road Force" to find any high or hard spots on the tire. Sometimes that can be lessened by rotating the tire on the rim. https://www.hunter.com/gsp9700

    The latest model is called The Road Force Elite
