i have an 06 PSD 4x4 with a six inch lift and 28000 miles on the clock. i went off roading for a little bit last night and shifted into both 4hi and low and back to 2 wheel as well. anyways when i got back on the road the thing feels like its stuck in 4 hi and when i got home it started making a grinding noise. it was really weird too because the truck drove very odd. like it kept wanting to jet off in one direction?????? anyone please help me out here!!!!!
