HI in this case more is not better. first off get the manual downloaded as steve has said. for safety sake i would pull the drums off and see if the grease has gotten on the brakes. you can use a good quality brake cleaner to remove the grease. then if needed repack the bearings by hand and REPLACE the seals. ther has been a good discusstion on packing wheel bearings on this forum. i do use the zerk fitting but every other year I take apsrt the drums clean the bearings check them for wear and repack them. if you do not know how to tighten the bearings when done fallow this. tighten the nut down till it is tight. then back it off ( the bearings are now seated. then run the nut till it just touches the bearing. you should have no free play and no pre load on the bearing if the hole for the cotter pin will not line up back the nut up do not tighten it to align it. then have a cold one..or two
