All the old service manual lubrication charts list the u-joint service as every 1000 miles with the cylinder oil/soda soap mix. The lube usually does migrate back to the driveshaft bearing & beyond after time. Some of the reproduction u-joints may have needle bearings and they likely won't hold up as good as the old bushing, ring, & spider set up. You may be able to salvage one end of that joint but the other looks toasty along with the spider & ring damages. It's pretty much inevitable that something will wear out eventually. The old cars needed more preventative maintanance that the new ones for sure.

The seal behind the front roller bearing could have been installed backwards, with the lip facing the rear of the car. It should be installed with the lip towards the front. It's my understanding that the inner axle seals and the drive shaft seals should all be installed to allow any pressure in the rear wheel bearings to vent away from the brakes and any pressure in the differential to likewise vent away from the brakes and allow that pressure to vent towards the transmission instead. IMHO
