New to me - maintenance Questions

Hello! Just bought this girl

2000 SR5 with 249k on it.

I’m now the third owner. First owners took good care of it and the older couple I bought it from owned it for 11 years and about 70k miles

Oil changes have always been on time

Last year they had a new radiator put on and new back tires ( I’m getting some front ones next week) battery and harmonic balancer. They also bled the breaks and did a power booster + rear breaks in 2020 and new battery about a year ago.

Runs starts great and no leaks. Ac is cold all electronics work I picked it up after a little haggling for $3700!

Here’s what I plan on doing ⬇️

- Spark plugs (no clue if they’ve been done any time recently though I did just dm them to ask but figured they never mentioned it and it’s not written down)

- Timing belt water pump pulleys etc (they didn’t do it but he said the original owners could have ) though I’m not in a massive rush for this as it’s above my pay grade, so it’ll have to be at a shop. and I know it’s a non int engine.

- rear dif fluid (I’ll do)

- trans drain and refill ? I’ve heard mixed on this. She shifts great. (I’ll do)

- inspect lower ball joints and replace them (I’ll do)

Anything else I should look into? Mainly just preventative. This will be my daily along side my motorcycle

Thanks! Cheers! Excited to do some mods too 🤠
