Suggested maintenance to keep high mileage 5th gen going strong?

[tauren]

I purchased my 2010 T4R in 2020 with about 211k miles. I had an inspection done prior to the sale that didn't find anything significant or alarming.

After purchase, I took it into a dealer who also inspected it and performed about $1000 of maintenance. Summary of the original dealer service:

• SYNTHETIC OIL. PERFORM REGULAR MILEAGE SERVICE PER TOYOTA GUIDELINES USING SYNTHETIC OIL, REPLACE ENGINE OIL AND FILTER, ROTATE TIRES. PERFORM MULTI-POINT INSPECTION. INSPECT BRAKES, TIRES, SUSPENSION, DRIVE TRAIN, FLUID LEVELS AND LIGHTING SYSTEMS.
• REPLACE REAR BRAKE PADS, RESURFACE ROTORS, LUBRICATE CALIPER SLIDE PINS AND CONTACT POINTS, CHECK FOR LEAKS, ROAD TEST
• MULTI-POINT VEHICLE INSPECTION
• Perform "4 x 4" service (Found rear differential fluid to be
  ;dirty/contaminated)
• Clean Throttle Body Based on Time/Mileage (Found throttle body to be dirty)
• Perform Fuel Injection'Service based on Time or Mileage (Perform iFuel Injection Service based on Time or Mileage)

In case you are interested, here's a redacted copy of the full service report:

For the last 3 years I've only done regular oil changes, tire rotations, and basic maintenance. It's now at 240k miles and is still running great.

I'd like to keep it running great for another 100k miles or more. I take it on dirt and gravel trails occasionally, but no serious off-roading.

I'm not a car guy and would love to hear your thoughts and suggestions on what issues I should watch for, inspections and maintenance I should do now, etc.

Wheres oil change for Transmission, Transfer case, Front and rear Diffs? Or is that all in the 4x4 service?

Also at that age if you havent already done it, change the brake fluid as its likely full of moisture and will boil to fast under hard braking

Rad flush and fill to at that age.

regular dealership BS, a lot of labor and minimum actual service.

Maybe he gets a free cabin filter for that crazy bill? :zoom:

I wouldn't overthink it. fluids will be critical as the vehicle ages

I would say anywhere from every 60k to 80k miles I would do the following:

transmission fluid
front, rear differential and transfer case fluid

then minimum once a year, oil change

spark plugs (and throttle body cleaning), brake fluid and coolant do as per the service schedule. you could expedite coolant and do earlier but probably OK under normal conditions. I don't live in the desert so I don't expedite

don't forget to lubricate driveshaft and check bolts for tightness

cabin and engine air filters as per schedule but you could if you wanted clean your MAF sensor every 6 months or a year. honestly I don't think it's worth it if you aren't using an oiled engine air filter. I cleaned mine for the first time after almost 150k miles and it looked brand new. I couldn't really the tell the difference before and after using MAF cleaner. I think this is really more of an optional thing to do but why not if you're already doing the engine air filer

one other thing I think many people forget is the trailer harness plugs. I use CRC contact cleaner and really spray it in there. if you trailer semi regularly these can get full of sand/ dirt. contact cleaner will help them stay clean

I would do oil / filter every 6 mo or 5K if mileage is low. Eg, I only do about 3K miles per year
