2004 , Explorer thud when slowing and stopping

[2Purfekshun]

when stopping or slowing down I am experiencing a loud thud and also feeling it. I have fixed the transmission, changed upper and lower control arms, changed breaks front and rear and changed ball joints. Please help this truck is costing me a fortune to fix

If you did all that work you probably already checked sway bar links right?
