02 4runner. on the zerk fitting on the front drive shaft (not u-joint) i think i may need to replace that zerk fitting. I noticed just a little grease leaks out and stays right where the silver ball is. Do i need to get a certain zerk with correct thread?

thanks!

 

I wouldn't worry too much about it, as long as you can pump grease in to the bearings, what does it hurt that a little dab leaks back out? It leaks out all around the bearings too. But yes, there are different thread sizes (metric and standard) for zerks just like bolts.

 

thanks. it should be fine for now... i was worried i might of messed thte fitting up when i pulled my grease gun off it.

 

I agree. As long as you don't loose all your grease as it spins at higher speeds - that is it only allows a little to flow back. Also - don't overfill the driveshaft grease points. You limit the ability for the driveshaft to compress if you do that and that could mean broken parts.
