Ok first off I have done some searching, just not found what I'm looking for so please help..
I just picked up an 03 Tundra yesterday. Got from a dealer with 128K on it and I'm wondering about some things.
First from what I've been reading, it sounds like it's crucial that I change out the timing belt. Crazy that they use a TB on a V-8, but what ever. I'm curious though, is there any way I can inspect it to see if it's been done recently? Heck if the previous owner did it at 90K or so then what a waste it would be to do again.
Also, my truck has the TRD package and is 4wd. I understood that some of these came with fully locking rear diff's and others with limited slip. Is there any way I can easily tell which I have? I would have assumed that for full lock I would need some button to engage it in the cab, which I don't see.

I think it was a push button lsd. Look on the rear end for a metal tag saying lsd or call the dealer and run the vin. That might tell you about the tb also. Did it have any service records? I've heard some write on the side of the tb cover when it was changed.

For timing belt if done the dealership should have put a sticker on the plastic engine cover stating date and miles done. Otherwise the only way to check besides taking apart t get at it is to check dealership records or find former owner and try and get records. Look for the metal sticker on rear diff for LSD.

If i'm not mistaken, no tundra has come from the factory w/a locking diff. It was either an open diff or LSD. The Taco's and 4runners(maybe others) had a locker, but i'm not sure.

The others are correct that if the timing belt was replaced there should be a sticker on one of the covers that states when it was replaced. If it's missing you can remove one of the viewing plugs and check it's condition. Now the problem with that is it might look good but it's not to say it's the originial belt. When i looked at the old vs new timing belt when i had it done on my '01, there was an obvious difference but if yours was replaced 40K ago, it might have enough wear so it looks old even though it's not.

Good info, thanks! This TB thing has me a little paranoid, don't want to drop $800 on a truck I just bought, sheesh! Not seeing anything stating or showing when or if the TB has been changed. Upon further inspecting, I did see some pink crap around what I believe is the tstat housing. Anyone know what this might be, I've never seen pink coolant, so I'm puzzled.

Pretty sure the coolant in my truck was/is pink...I think. Had the dealer change it with the water pump & timing belt, since I didn't have a place to dispose of the waste.

If you can't tell if the belt was changed at 90K, do it. It's 800$ in to a truck that is unlikely to need anything else major until the next timing belt change interval.

Tundras never came with lockers...only LSD. You can get a selectable locker from ARB, and I highly recommend it if you plan to do any 4wheeling.
