92 lowrange
 

ey im wonderin if anyone knows about this problem. i got a 92 f150 efi 351w 3"body 6"suspension, d44f 8.8r e4od trans. reg cab. and the problem is that when i try to take it down to 4lo it wont go, it says it does on the dash,(4x4 selector is on the dash) but when i accelerate or reverse. NOTHING. its like im in neutral just reving. and when i take it out and go to 4hi, it makes a grinding noise like it is barely missing the gears, am i putting it in right? i gotta have the 4hi on before i push the 4lo on.otherwise it wont go.

NEW GUY

you have to have your truck in neutral BEFORE you try to engage it in 4LO

truck must be in nutreal and i usually try to do it when the truck is rolling like an half mile an hour to 1 mile an hour...just so its like BARELY rolling and it always goes right in... its a 93 f250 diesel tho too
