My car ran fine all the time till about two years ago i hit a gigantic hole on with the passenger front tire. i was going maybe 10-15 mph. i was on a road trip and about after 120 miles a horrible shaking started to occur. the weird part is it comes and goes. the reason why it was 2 years ago is it the shaking stays for a week and goes away for a couple months. as the months went by the shaking got more frequent and worse. i have looked at numerous times looking for wear and tear from a pot hole and everything else, being convinced it was the drive axle i replaced it and no change. Here is the description of it:
1) the steering wheel does not shake
2) its more shaking in the seat and by the feet( now pretty much the whole car is shaking)
3)it shakes on acceleration between 35-50 mph
4) sometimes shakes on hard braking
5)checked for play in the suspension couldn't find any
6) it is the worse going up a hill
7) while coasting no shaking.
8) it shakes no all the time but before when it came and go when you take your foot of the gas and push it again the shake would go away and then come again after a couple mins again

Any suggestions would be helpful thank you
