just hit 90+k miles

whats the major up keep/ tune ups for 90+k miles

 

Well... whats been done previously and at what intervals?

 

just the oil changes and a trans oil flush. figuring ill need a timing belt change and some other things soon.

 

Have you ever changed the rear diff oil?

 

Your pickup has a timing chain, not belt, and is good for 250k IIRC...

Plugs every 30k miles, most use Denso k20hr-u11
Look here for the low down: https://www.tacomaworld.com/threads/2nd-gen-diy-maintenance-quick-reference-guide.438945/

 

Edit...

 

This x100.

Change that rear diff every 30-40k. Spark plugs too. Front diff and tcase (if 4x4) are overdue as well at 90k.

Getting up around 100k you might consider the serpentine belt as preventative maintenance (and keep the old one in the truck as a backup)

 

Fill the tank

 

Do you have the factory Maintenance book? It has everything that you need to do every 5k. From oil change, to diff fluid change.

Grease driveshafts
Cabin filter
Clean throttle body and intake manifold
Power steering flush.
Coolant flush.

King suspension

Checklist them all

 

Along with everything else mentioned already, check idler pulleys, check inside the boxed frame areas for rust, do a search on here and you will find your answers and how to accomplish them.
