IMPORTANT!! READ BEFORE REBUILDING!!
EMF BALL JOINTS ARE REBUILDABLE AND YOU CAN TIGHTEN!!
- THE LOWER BALL JOINT CAN BE TIGHTENED BY BACKING OUT THE SET SCREW ON THE SIDE OF THE BODY AND TIGHTENING THE RING. THERE IS A VIDEO ON HOW TO DO THIS ON OUR YOUTUBE CHANNEL , USERNAME IS EMFEVO (EMF ROD ENDS) IF YOU WANT TO CHECK IT OUT.
- FEELING ANY PLAY? HAVE THE JOINTS BEEN GREASED? SOMETIMES THEY JUST NEED GREASE AND IT WILL TIGHTEN RIGHT BACK UP AGAIN. WE RECOMMEND GREASING AROUND EVERY OIL CHANGE JUST TO MAKE IT EASY TO REMEMBER.
- GREASING GUIDE:
GREASE THE LOWER BALL JOINT FIRST UNTIL THE GREASE GUN STARTS TO BECOME FIRM. THEN GREASE THE UPPER BALL JOINTS UNTIL THE GREASE GUN BECOMES FIRM. THEN GREASE THAT LOWER BALL JOINT ONE MORE TIME UNTIL THE GREASE GUN BECOMES FIRM.
ROTATE THE KNUCKLE SIDE TO SIDE TO DISTRIBUTE THE GREASE INSIDE THE BALL JOINTS. THE KNUCKLE SHOULD GO FROM STIFF AND HARD TO MOVE, TO EASIER TO MOVE SIDE TO SIDE FREELY.
NOW YOU WANT TO REPEAT THE STEP ABOVE AGAIN BY GREASING THE LOWER BALL JOINT FIRST AS MANY PUMPS AS YOU CAN GET, FOLLOWED BY GREASING THE UPPER WITH AS MANY PUMPS AGAIN. IF YOU CAN’T GET ANY MORE IN, THAT’S OK!
CYCLE THE KNUCKLE BACK AND FORTH AGAIN GOING FROM STIFF AND HARD TO MOVE TO EASIER TO MOVE SIDE TO SIDE.
IF THE KNUCKLE FEELS TOO STIFF, THEN DEPRESS THE GREASE FITTING TO LET A LITTLE PRESSURE OUT AND IT SHOULD FREE UP AGAIN.
- ARE YOU GETTING SIDE TO SIDE PLAY ON THE UPPERS? THAT IS THE ONLY TIME YOU SHOULD HAVE TO REBUILD THEM. UP AND DOWN IS NORMAL FOR THE UPPER BALL JOINT BECAUSE IT IS A KING PIN DESIGN. SIDE TO SIDE FOR THE UPPER IS NOT NORMAL AND COULD INDICATE WEAR ON THE INTERNAL PIN AND RACE. TRY GREASING FIRST AND SEE IF THAT HELPS… IF NOT, REBUILD WITH A NEW PIN AND RACE SET.
- ARE YOU GETTING UP AND DOWN PLAY ON THE LOWERS? BACK THE SET SCREW OUT AND TIGHTEN THE RING TO GET RID OF ANY PLAY. WHEN YOU GET TO THE POINT WHERE THIS IS NO LONGER EFFECTIVE IN REMOVING ANY UP AND DOWN PLAY IN THE LOWERS, THAT IS WHEN YOU REBUILD WITH NEW RACES AND PIN.
