Shakes or Wobbles problem
1997 Ford F150 V8 Four Wheel Drive Automatic 241000 miles

i have a lifted f150 on 35s and i recently had the front right hub bearing assymbly replaced. i am still having shaking/wobbling problems. the driver side ball joint seal is leaking and needs replace....when driving around 30 it will get caught in almost like a vortex of shaking meaning it will shake and it feels like all 4 wheels will shake once i slow down and start driving agian its fine....on the highway around 50-60 the shaking is still there but mild compared to at 40 -50....once i hit 65 its almost gone....now once i step on the gas there is no shaking going on...once i release the gas and i am around the 50-60 range the shaking begins....i did notice that when i going to take off the right side wheel to replace the hub bearing assymbly the lugs are a bigger lug compared to the other 3 tires....the other thing that is getting some attention is the rear leaf springs need to be repaired they are shifting alittle...i am not sure if this will contribute to my shaking

thanks
