On the hi lux the tailshaft/ drive shafts are supposed to be greased every service, 4x2 3 grease nipples, 4x4 6 grease nipples
i usually take my hi-lux to Pearl Toyota and watch what they do through the observation window and have never seen them do it
Got my stepson to take the hi-lux to the dealer we bought his hi-ace from ( phuket town Toyota) and service it there and tell them the tail-shafts must be lubricated
They did not have a grease gun to do it with so my stepson after the dealer finisher the service took it to a friend of his who has a workshop and a grease gun and had it greased there
I will be using his friend for all future servicing just buy my own oil and filter and any other required parts and pay him his set service fee
