I've had to repair/replace quite a few things in the front steering/suspension due to lack of maintenance. Don't think the previuos owner had ever heard of a zert fitting.

CV boots, ball joints, steering knuckle,repack hubs,replace brake pads,shocks, bushings, etc. Nothing too difficult, just time consuming. Made a huge differenc in road feel though, I'd say worth it in the long run.
Might check it all out while the head is bieng machined.

Might as well drain a refill your diffs and trans while your already dirty.
