You can oil these but it will make the noise again in 12 months time .
I use a syringe full of oil and molly slip and a tube on the end push it through the hole the arm comes out off and let the dame thing have it all . If you do replace them get the ones with a plastic cover over the works . Then before fitting fill the cover with grease replace the cover and fit it in place . Do repair it or ,,this noise you hear will damaging the hole the rear of the check strap is held in to the door . This car i have came with both front doors doing this .It was like a gunshot going off .And when i replaced the one the hole was damaged in the door .The hole to fit the rear of the check strap had been damaged by the strap retaining bolt moving inside the hole,, and it was now ellongated . On refiting the new one i used a penny washer to fit the dimple in the door before pushing the bolt through . You can repair these check straps .Rust gets in the bearing serface .You will need a very good vice to compress them but it can be done.
