30k service

[Tooltime19]

Im preparing for my first 30k service, and I want to know if there are any upgrades or special things I should consider while performing this service such as plugs ect.?

I don't know what the maintenance schedule calls for on the V6, but the spark plugs on the V8 are good for 80k or 100k miles if memory serves.

One thing I would suggest doing even thought the maintenance schedule doesn't call for it is replacing the gear oil in the diffs. The rear diff at the very minimum. When I replaced the gear oil with Mobil 1 synthetic at 30k, I was very glad I did. The original gear oil was very dark and the drain plug magnets were covered with fine metal shavings.

Other than that, there isn't a heck of a lot you need to do to these 4R's at 30k. Maybe change the cabin air filter (they get dirty, quick!). Also, I would lube the 6 fittings on the drive shafts if you haven't done that yet either.

:iagree: and would add do the t-case oil, why not? If it's a V6 it should have spark plugs. Only the V8's get the long-life plugs from the factory.

thanks guys for the info. the v-6 does call for plugs, and I was planning on replacing the diffs with mobile 1 as well. two questions though, first, is their a plug aside from the OEM Denso's or NGK that would give any benefits? Two, with our rear diffs and center locking diff, do I need to add any friction modifier, or is regular Mobile-1 ok?
Lastly GIG, how do you like your Revo's, and how hard do you use your rig? Oh and one last question, what is the rear breather mod and what do i need to do it?
Thanks

Denso's or NGK's are good. There are many "snake oil" plugs out there that won't do much other than lighten your wallet.

Choosing a NGK or Denso long-life Iridium might be nice but other than that I wouldn't bother.


No friction modifier as the diffs are open diffs with an ATRAC overlay that provides the limited slip. There's no mechanical limted slip involved.

Like CJ said, no friction modifiers are necessary. Mobil 1 is good stuff and I feel better that I am running it in all my diffs now. I also agree with CJ and that there are a lot of gimmicky plugs out there. I would probably just stick with the stock plugs.

I love my Revo's. They are not cheap but you get what you pay for. If you do a lot of wheel'n I would suggest at least a LT metric AT tire. I have the P metric Revo which works well. Great on-road manners but tough enough to handle some of the wheel'n I do. I am a moderate wheeler (about 5-10 runs per year) so they do trick. I was actually just watching a video on Bridgestone's website about the new Revo 2. That looks like a sweet tire as well, but there are a lot of good AT tires out there.

Finally, the rear diff breather mod isn't necessary unless you go wheel'n and might experience a water crossing over 6-8 inches. Below is a link with more info about the mod, why you might need it, and how to do it. It only requires about $30 worth of parts and about an hour (or less) of your time.

On the diff breather mod; I'd do it even if you don't plan on fjording the 4Runner. More than one 4Runner has run into rear axle seal issues as they age.

Strictly an IMHO: I believe some of the issues center on the OE check valve in the vent. It allows the axle housing to develop a suction or negative pressure inside the housing when it cools, especially after a long ride that warms the axle. When you start up on your next trip the axle is running with a negative pressure pulling the seals "in" promoting wear. Whether it's an issue or not is for you to decide. I know I parked my '07 overnight (prior to modding the vent) and then checked the fluid level. There was definitely a considerable suction when I removed the plug; suction can't be good.

Just a suggestion...

Whats the torque on the prop shaft bolt?
