Default Thumping noise/feeling on floor board??

I have a 2001 PT limited with 139K miles on it. I just replaced both of the front bearings, new break pads, and had the rotors turned less than 4K miles ago.

** Side note - thanks to all the posting here, because it walked me through the entire process without any problems.

Everything has been fine since then, but now anytime I get to 70mph or faster - I start to feel a thumping in the floor board. I'm thinking it may be the drive axles but wanted to see if anyone else had seen this issue or might point me in a different direction.
Thanks

I don't think the drive axles would thump on the floor (I could be wrong). I'd get it up on a rack and check the whole exhaust system especially the loop that goes over the rear axle. It could be hitting there.

I'm sure the thumping I feel is not in the back of the car. I can feel it on my feet and tell it is coming from the front of the car, like it has something to do with rotation. Like the feeling you get when a tire is out of balance and has a hop to it.

Welcome.
You tighten up the bearings properly?
Did you have tires checked?
Drive it up on ramps and look at all suspension links - check the bushings.

Did anyone determine the solution on this one?

I have the exact same thumping noise though only around 25mph & 45-50 mph... ive looked around the suspension and cant seem to find anything wrong (at least thats obvious...)

Thx.

Exclamation Re: Thumping noise/feeling on floor board??

and a vid to show how excellent the thumping sound is.

What's odd is that it can vary when it actually happens based on the surface, which leads me to believe it's likely a bushing issue, but also could be some kind of end-link or ball joint...

Talking Re: Thumping noise/feeling on floor board??

Decided to play with my webcam, netbook, and some duct tape.

No diagnosis yet, but if I can get some time to play I think I can figure it out. It's just GOTTA be one of those darn bushings...LOL.

Edit: and this is on a pretty smooth, newly paved road.

mine was doing this also @153k. i just replaced the LCA bushings with poly's last night. Haven't driven it yet but i feel confident this was the source of my clunking. I'll updated after my drive to Dunkin's this morning
