hi guys and girls, so today i decided to put in new front drive shaft uni joints. all was going well until i went to unbolt the front drive shaft in which all 8 bolts had seized up and it made it very difficult to get them off so in the process i managed to wreck 6 out of the 8 bolts, now i rang Nissan for some replacements but he said he couldn't get any for a week, so i went to my local fasteners and got some 8.8x40mm bolts and proceeded to fit them up. my question is that here were no spring washers or lock nuts on the origional Nissan bolts so should i get lock nuts or spring washers and put them on, or just use some loctite, which is what it looks like was on there?
