    New to the forum. Curious when y’all went about the timing belt and head gasket changes. How many miles and what is the best upgrade when time to do so?

    Welcome. My 2019 4R ORP is the 3rd Toyota I’ve owned (1985 Hilux 300,000+, 2003 Tacoma 4x4 still going with 250,000, and now the T4R). Never had to open the engine on any of them. Toyota uses internal timing chains rather than belts so they’re more reliable and last longer. Do the factory recommend services on schedule and you should be just fine.

    Dear Fellows, someone know if the rear diff of a 2008 4x2 sr5 4.0L is a limited slip or is a normal diff? the question is because I heard if I put a non LS type into a LS diff type this will broke my diff.
    Looking forward to hearing from you, also thank's in advance. (sorry for my english, is not my native language)

    Yes, every 90k, timing belt, 96-02. I’ve got 60,000 until my next belt. I’m on my third...

    Read your manual do what it says when it says or sooner if it makes you feel better.

    Timing belt is 90K as others posted. The head gaskets shouldn't need to be replaced

    I did my RD on SR5 2005 V6 with 150,000 miles in the driveway with Valvoline 80W 90 (3 quarts), and it was 1/2 hour job - no mess. The differential type doesn't matter. Only cars have slip D, but you can research further.

    HG is big expensive job. Only 1% get it after 150,000 miles, but those that do think everyone 4runners get it. Misery loves company.
