Have read 105k miles or 84 months, whichever comes first, but have never seen this in any official Honda document. My 2010 MDX has a MM and there isn't an old fashioned maintenance schedule in the OM or FSM. My X is coming up on 7 years but has only 55k miles. I recently replace a 9 year old (50k miles) Mitsuboshi TB on my 99 Avalon and it looked absolutely brand new. I swore I would never change another TB based on age but I am getting cold feet. If I do replace the TB, I assume other components such as WP, hydraulic tensioner and idler bearings do not fail based on age and do not need to be replaced unless they are showing signs of failure, e.g. hydraulic tensioner is leaking or bearings are rough? Thanks.
