2002 Tundra timing belt.......replace?

[Lend273]

My 2002 Tundra has 140,000 trouble free miles on it.
I have used Mobil 1 since the first oil change.
My dealer keeps telling me I need to replace my timing belt.
I'm of the opinion that "if it ain't broke, don't fix it".
Should I replace the timing belt as he suggests?
If so, are there other components that should be replaced at the same time?

As a side note, pulsating front disc brakes seem to be a common problem on Toyota Tundras. Is there a long term fix for this problem?

Thanks for your advice.

You will want to post this in the correct forum as you'll get better response. This space is for 07+ tundras, so guys around this part probally aren't real familiar with your question.

Yes. Replace the timing belt, like YESTERDAY! If the belt breaks, you will feel the pain in your wallet

Along with the timing belt, check the water pump. If your vehicle uses ethylene glycol as a coolant, you really need to check the water pump. Don't worry about Gen 1 vs Gen 2 post. Lots of us had Gen 1 Tundras. Good luck.

Good point on water pump. I also had 2 Gen. 1 Tundras. Great trucks!
