Any suggestions on mainteince for 100k miles?

Register to hide this ad
Mine is at 102k, picked it up with 99k and so far I have done oil and filter, spark plugs and wires, clean MAF and throttle body, flush transmission fluid and drain and fill differential fluid. Still plan on flushing the coolant and brake fluid and pwoer steering fluid looked fine. The things you listed I wouldn't really bother with until they start giving you plroblems.

I didn't know my trucks service history so I was keen to start fresh with all new fluids. On the last road trip it got 22.67 mpg! Disclaimer: 2wd driving in Florida lol
 
I certainly would not do an alternator as PM. The factory Denso's are pretty bulletproof, except for the solenoid contacts. But even those give you warning. I would think a new aftermarket reman would be a downgrade from a 100K Denso, so sure as sh** don't do that.

I'm at 130K. I did, between 90K and 120K:
All fluids, including brake and power steering
Timing Belt
Water Pump
Thermostat
Idlers
Tensioner
Accessory belts (all 3)
Fuel Filter
PCV
Both O2 sensors (both failed but consider at least front for PM at 100k--they will go soon and front may improve performance if new)
Shocks (springs were fine)
Rack Bushings (needed it, yours probably do, too)
Sway Bar Bushings and end links (one link was broken)
Fan Clutch (failed, but I'd consider for PM)
Plugs and Wires
MAF/TB clean
Battery (failed)
Tires (with 70K)
Brake Pads in front
Clean, lube and adjust on rear brakes including bellcranks

I really have nothing else planned as PM for quite a while other than repeats of some of this stuff. (I left out driveline grease and air and oil filters, obviously). Check the rest of your suspension and do what's needed.

Replace the radiator, or install a stand alone tranny cooler. At least according to the many many threads on the infamous Pink Milkshake syndrome that 4Runners have around 10+ years or 100,000+ miles. Just do a search on "Pink Milkshake" and you'll see what I mean.

Definitely. I have a manual or I would have done that, too.
 
100K most important if it hasn't been done at this point would be the timing belt, while you are there do the water pump and couldn't hurt to do crank and cam seals too.

just my $.02

How do you flush the power steering fluid?
 
A new radiator cap is always a good idea. OEM ones can be had online for less than $12. I was amazed on how much faster a new one made my coolant heat up vs. the original one. Also, if/when you replace the radiator and/or thermostat, replace the upper and lower radiator hoses with OEM ones.

Breather cap on the rear axle is also a good but cheap replacement. That you don't want to fail-get stuck.

Also check lower ball joints and the valve cover gasket(s) for leakage.

that is not the most important, these motors are non-interference motors so if the belt does break it wont do anything other than shut the motor down and turn it off. and they can go well past 120k with no problems, ive heard of them lasting over 160k before. id do what thedurk said, it looks like a long list but its a good list and really not all that bad. the only thing i would add to the list is LBJ, its $150-200 in insurance to prevent a possible $2-4000+ in potential damages that could be caused by one failing. even if you are stock its still a good idea imo
 
Does anybody know what's the OEM part number for these parts?

lower balljoint
tie rod
steering rack bushings (i think is what it's called :wink2:)
