Greasing the universal joints on my front drive shaft (tranny to front diff) having a hell of a time greasing the one closest to the engine. I was able to make my grease gun nozzle "skinnier" with a trip to the grinding wheel so I can do the front joint but no way no how can I get the grease gun on the grease zerk on the rear universal joint. My grease gun has a flexible hose so that is not an issue. Got about 3,200 miles on it and I don’t think the rear joint has ever been greased. Starting to get that dry rattely sound from the drive shaft area when traveling 30-35 mph or so.

What’s the secret to greasing the rear universal joint on the front drive shaft?
