Truck and vans, one ton and HD3/4 tons with the Dana 60's also use the rearend oil as a lubricant, not grease. Whenever you turn a hard left or right the oil is sent to the bearings.
I hate chinesium socks as they wear holes way too fast. They get a verbal darn way faster than it is possible to do the mend darn.
I really do not trust Chinesium skivies. After the lead paint children's toys and melanine in milk BS, I have no faith in what may be in the dyes. The C19 load of lies, with nano lipid graphine oxides and mRNA jab scam, I developed an even greater aversion to the recycled Yak turd ****. Those in the WEF, WHO and UN should all be in jail.
