"thunk" in drivers side floorboard

[DT620]

I can feel a hard thunk under my feet when I hit bumps and dips in the road. I just replaced the bushings in the sway bar and end links. Any help would be great. It's a 2004 f250 crew cab 4x4 with 148k

I have the same thunk you speak of. I replaced all sway bar bushings as well and it seemed to cure it for a little while but appears that It's back. The next thing I can think to try is shocks.

That was my next thought as well. I'm going to be putting on a leveling kit soon and replacing the shocks with it too. Hoping that this will fix it.

I had the same thunk....the bottom bolt on my driver side shock was loose and about to fall off...tightened it up and noise went away.

I have the same thing, My body mounts aren't tight. The bonehead who did my first stud job must not have felt like tightening them should be included in the thousands I gave him

my thud was caused by bad tie rod ends. There was excessive play in both ends (up and down)...I replaced them with new MOOG ones got an alignment....after a week with no issues its back. Both new tie rods have up and down play in them.....causing a THUD when I go over bumps

After replacing my tie rod ends.....I started to hear the "thuds" again but they were not a loud as before.

After scratching my head for a couple of weeks....I believe I have found the second reason for the "thuds".

I believe my front hub bearing are bad. The reason I believe this, I can move my front axle shaft (at the U-joints) up and down...which also made the "thud" sound.

I'm going to replace my bearing next week...I will let you know if it fix it.

Isn't there supposed to be a little bit of play in the u-joints?
