Pulled my driveshaft today to regrease it and get rid of the driveshaft binding bump at stop lights.
This is how it came out.
It appears to me the the grease simply gets used up and vaporized as there was very minimal grease left on it when I removed it, female side looked the same.
There's no grease in the plastic accordion dust boot nor any running down the driveshaft, its just gone.
Below is same way I greased it 25K miles ago
Now re-greased and ready for reassembly.
About to run some errands and will check it but I am 1000% confident that it will butter smooth again just like last time.
Took about 5 min to remove and 20 min all together. Toughest part is compressing the two halves together with that grease; aligned/phased the 2 shaft halves, put a new clamp on and done.
Yes my truck is under warranty and they would fix this but I'd have to take it in, spend 20 min talking to them, get a rental or a ride home then be without the truck the 1-5 days it would take them to look at and address this. Took me 20-30 min including putting tools away. Dealer service isn't worth the time for this.
