Hmmm.. helpful.. very much appreciated. Although I have doubts if it will personally help me.. But I have friends who are truckers too, and for sure this post can help them. For sure I'll refer them here once a problem pops up.
I don't usually do the lubrication of my truck. Since it is done no that often.. When it is in the shop for a check-up.. that's the time I consult mechanics if it should be done.. and let them do it.
