23 ST with 11k mixed highway / hard back road driving on weekends. In for a window seal service and wanted to knock out some fluid changes while they had it. Asked for an oil change, trans fluid change, rear diff change, and ptu change. Starting to think I should be kicking myself for not asking to run the front diff change as well. Wanted to be cautious as it's also heading for a tune as soon as service is complete and trying to extend reliability for as long as possible. Probably a bit paranoid to change these now...but what's the community think. Bite the extra 299 cost and add the front diff if they haven't gotten to the fluids yet? Next planned drive train fluid change aimed for 40k.
At 11k miles you don’t need to do any of those fluids. At 40k or so is where I’d recommend doing them.
