My outer left CV joint boot is torn. A new one is coming any day now. In the mean time the joint started to make a rubbing noise this morning. It has probably lost all of it's grease. Can I squirt in any grease temporarily until the new boot comes? I need the car daily and I don't want to damage the CV joint. I replaced it about 30K miles ago. TIA Don Hoefer '82 Coupe
