Preventative maintenance on a high mile 08 4x4

I travel weekly 6-8 hours round for hunting season. My taco is now at 244k miles and I have replaces quite a bit of part but want to know what I am missing.

Things I have done in the last 20k mile:
Inner/otter tie rods
Rack and pinion
Serpentine belt
Both uca with bearings
All shocks and leaf spring
Transmission empty/refill
All diff oil
Oil sensor
Driver side rear wheel bearing
Brakes, drums and rotors
spark plugs
Alternator
Battery

things I plan to do:
Throttle body
Pcv
Maf
Coolant

 

Sway bar bushings and sway bar end links.

 

Not sure if part of your "coolant" maintenance also includes checking/replacing hoses but if not, I'd add that to your list. Mine is a little over 210k now and replacing ALL coolant lines will likely be my next big maintenance item (I've done pretty much all the same stuff you've done.) My hoses look decent but a coolant leak could easily strand me so I figure it might be good preventative maintenance. Last thing I need is to be stranded out in the middle of a trail hours from civilization.

Have you checked your LCA's? I recently replaced mine as the bushings and ball joint were pretty worn.

As part of your brake job I'd also take a look at your brake lines. I opted to replace mine with stainless steel ones - which have a performance benefit and will be much much durable than 10-15yr old rubber ones.

 

I didn't see where you did the Transfer case fluid?

I'd also not recommend replacing the MAF.
I'd clean it, and the throttle body.
No need to replace parts that work. In todays world, New doesn't mean good.

 

Linking to the almighty 2nd gen maintenance quick reference thread as a good starting point for all the things:
