What items in the 90K Maintenance Check can be DIY?

What items in the 90K Maintenance Check can be DIY? A dealer or other will charge a lot I think.

I routinely get the oil changed and the tires rotated for a reasonable, low cost.

I've attached a picture from the Maintenance Manual of the 90K checklist for the Yaris

I have determined that a local, very reputable repair chain will do the brake stuff (Lines, hoses, linings/drums, pads/disc) and steering gear box and steering linkage & boots for free.

I've already done the engine coolant, fuel tank gas cap gasket, radiator and condenser myself (I think). And I have checked the brake fluid level myself (not on the list). And I just learned how to replace the serpentine belt here on another thread I started.

Is it possible for me to do the other stuff myself? Like ball joints and dust covers, exhaust pipes and mountings, front differential oil, fuel lines & connections, etc., and transmission fluid or oil.

What about tightening the nuts and bolts on the chasis, since I have driven on dusty roads.

Thank you,
