Hey guys quick question for all my G35x owners. Can you replace the U joint on the front and rear drive shafts or do we have to buy a new shaft. Mine are looking real iffy the grease is all over the place that was in the U joints and it looks like there on the way out. thx for the help.

 

I've never tried, technically any u-joint can be replaced but it might take some work sourcing a replacement since I don't remember Nissan ever carrying a replacement part.

Normally you replace the entire driveshaft on this vehicle, you can get a lower mile used one for about $100 on eBay usually.
