Hello Brett! I am a follower of the Volvo newsgroup and saw your post. Since you offer advice for free, and it seems to be sound information, I ask you this question...
I have a 1974 Plymouth Trailduster (Dodge RamCharger). It is full time 4 wheel drive, locking front end (Spicer) and LSD rear end. It is equipped with a 4 speed standard transmission (New Process) and a 360 V-8. I will likely not live in any area that gets below -10F. It likely will see temps in excess of 100F.
What should I use to lubricate the engine, diffs and tranny? Also, what grease should I use for wheel bearings, and front end pieces?
I would appreciate any and all help you can advise, thank you for your help!
