Need suggestions on maintenance for 79 K10

[ScottH]

Just bought a 79 K10 with 350/350/NP203 combo with 92K on it. PO wasn't the hands on mechanical type so pretty much just did what was needed. This is my first 4x4 truck and could use some suggestions/recommendations on what type of maintenance (other than the obvious) you guys would suggest. I'm wondering if the full-time hubs, or transfer case, axles, etc. should need any attention.

Any help is appreciated. Happy holidays to all.

Thanks.

Scott
