clunking and vibration

hi i have a 95 4.6hse the past week or so i have had a horrid vibration and clunkin noise i got told it was the wheel bearings so i have replaced both hubs on back cos it was easier than splitting them now i have a clunking noise coming from what sounds like the back passenger wheel it does it in drive and when free wheeling but not in reverse any ideas....

thanks

Does not sound like wheel bearings to me, check propshaft UJs for wear and diff for backlash and lateral movement in drive flange.

garage just phoned me diff knackered
