Here's the mechanics reply to my queries:
Coolant flush/cleaner:
Coolant can be checked for protection level and acidity, but coolant service is usually recommended around 120,000 miles. Ten years is also a good recommendation. Process involves adding a chemical "cleaner" to the system, letting it circulate with the thermostat open, cooling down, draining radiator and engine block, adding BG coolant additive, refilling and verifying heat works, no overheats and no leaks. Cost is $196.39.
Brake fluid/flush:
Brake fluid is a lower priority for me. Brake fluid boiling point drops with moisture absorption. Also, copper content could also show signs of breaking down. Complete brake fluid exchange costs $147.28.
Front transfer case (link for dealer photos, etc: http://www.mkvwa14.com/p/JUxCnR.html)
Transfer case and rear differential fluids are recommended every 60,000 miles. Factory Mazda SG1 fluid in both units. $105.60 for one or $211.18 for both.
Front outer tie rods (link for dealer photos, etc: http://www.mkvwa14.com/p/JUxCnR.html)
I don't service for cracked boots. Cracked boots allow dirt and water in the joint and grease to come out accelerating wear. I replace it when there is play. This picture looks like someone squeezed the grease out since it is on the top and bottom as well.
Front lower control arms
Same thing as the tie rod. This is a picture of the ball joint boot. Someone squeezed grease out for the picture. Replace when there is noise or play.
4 wheel alignment
Always recommended and/or needed after replacing suspension components. Also, an alignment check isn't a bad thing to keep tire wear even. If tire wear is even and steering wheel is straight, alignment may not be needed.
Transmission fluid/flush (filter?)
My recommended transmission service is by every 60,000 miles, depending on use. I will also recommend based on age (5-10 years). I remove the transmission oil cooler, install an adapter, inject a cleaner in the system to help suspend particles, exchange the fluid with 12 quarts of transmission fluid (as fluid runs out the cooler, it is captured and new fluid is injected at the same rate), install fluid conditioner and verify oil level. I use 12 quarts to dilute the system and get as much fresh fluid as possible. That service is $318.70.
