Question by Matt: How do you lock the hubs on a 1986 K5 Blazer?
Im considering to buy a 1986 k5 blazer (Silverado trim package). The thing is im not sure how to properly lock the hubs to go into 4×4. Also im not sure if it is automatic or manual locking.
Please tell me in detail.

there are millions of auto lock hubs out there on gm products, manual lock hubs have a twist lock on the end of each hub, so if there is no twist lock on the hubs, they are automatic, some years you can put manual hubs on, most rigs after 90 up to the present day are automatic, this is a bit harder on gas because the whole hub turning, whereas with manual hubs just the wheel turns.
