Loose rally wheels

[mikey531]

I have rally wheels on my truck and I have been slowly venturing out on longer drives. Today I felt a vibration in the steering wheel and discovered the acorn lug nuts were loose on all 4 wheels ! There were some that I couldn't turn with my fingers but some I turned with my fingers ! I wasn't far from home so I nursed it back to the garage. I torqued all the lugs to 85 FT LB and went for a 7 mile drive and the fronts were loose again. I took the wheel off and checked to make sure the acorn nuts were not bottoming out but everything seems normal. I did take off the center cap and torqued them to 100 FT LB. Anyone else had this problem or what did I miss? Thanks!
