Help loud Thumpin

[blkstrcj]

I have 95 LSi AWD, It started a week ago when i was sitting at a stop sign when i accelerated the had a huge shutter from the front-end and then it there was a thump when the car went forward and it got harder and louder the faster i went luckily i was only two blocks away. when i got to my house i had to parallel park and when i put my car in reverse pressed the gas the thump was so loud and hard i thought i backed into someones car, Since then i have replaced both axles but the thump only got slight quieter, i'm out of ideas some someone help please.
