200K Maintenance

So i bought my truck in April of last year. i do not have any history on the truck as far as what has been done to it before i bought it. So i changed out several fluids. Diff oil, engine oil, trans flush, radiator fluid. As well as air filter and cabin filter. At 200K what other things should I replace?

 

Plugs?

 

Did you swap both diffs and transfer case oil? I think it was 2014 that the TC went to 75w. Was previously 75w90…

Edit: OP’s truck is 2wd

Power steering fluid
Brake fluid

 

4WD or 2WD?

 

2WD

 

Spark plugs
Power steering fluid
Brake fluid
PCV
Maybe preemptive change of headlight, brake, and turn signal bulbs.

 

+1 on Spark plugs, PS fluid, Brake Fluid, and PCV valve. I'd also add engine and cabin filters, serpentine belt and tensioner/idlers, grease the zerk fittings on the driveshaft, and inspect your tie rod ends. Don't forget your blinker fluid and muffler bearings...

 

My driveshaft has no zerk fittings but i will check and replace everything else. Thank you all.

 

8 months later...
I recently got a Sequoia with 200k+ on it.

For certain, check front turn signal bulbs and their sockets. Sockets were burnt & cracked on mine and barely holding the bulbs. These bulbs double as DRL so almost always on while driving.
Look at headlight bulbs too. Could see filament in mine were worn and rough looking.
