2003 base model...lubricate the front end?

The "stealer" says the front end needs a lube...the book doesn't say anything about lubing the front end, like in the older trucks. So I think the stealer is wrong...correct me if that is not the case.

Having said that, is there anything we can do to extend the life of our front ends? (aside from not hitting potholes, etc, changing the shocks when worn out, beating them up on a dirt road). In other words, is there any preventive maintenance we can do?

thanks
