My ranger will want to change lanes or drift to the left or right on its own .. Thats with my hands on the wheel .. I checked and every thing looks fine .. I put new tires on it to see if that will help .. That did not do the trick .. I look under the truck and there are no leaks that i can find ..

does any one have any ideas

 

your alignments off. go to an alignment place and get an alignment.

 

first check your inner tie rods and outers. and check ball joints if any of that stuff is bad it will wear out your tires super quick and wonder all over the rd. after checking and replacing parts then go to the shop and get a good alliment make sure thay check camber too most shops dont check that. thay just set the tow and let it ride
