Not sure on your towing numbers but towing a race car and other equipment seems like it would be too much for the 4Runner and keeping it within safe boundaries for handling and braking.
I am frankly surprised. Not a knock on the 4R, but more on the V6 issues in the Tundra and probably the sequoia. Have the issues, cause, effect and resolution been done.
Do they publish a vin list of impacted vs no impact?
I was in the market for a Tundra and the issues with the engine stopped...
Is that in the manual?
i was under the impression that putting in 4hi for a few hundred yards once a month is enough to exercise the servo motors that activate the mechanical stuff. They are likely to cease up with non-use.
when you say “gearbox”, do you mean transfer case?
would like to see...
Sorry I cannot answer your questions directly but these switch blanks and the housing are a source of one of the many interior rattles. If you do pop them blanks out you might want to slap some silicon seal or something else to prevent the plastic on plastic rattle.
Maybe in the next year someone who is unbiased and not selling a product will tear down a high mileage 4R head and inspect the valves. I guess a bore scope might give some indication of buildup without removing the heads.
4R should run 87, LC premium. Discussed and debated in many other posts. No advantage to running premium in 4R.
No value in discussing again here for the OP.
I like the LC but would also consider the GX 550. However, when in that price bracket, other brands come into play too unless you are...
I respectfully disagree. The 4R is setup for 87. Yes, will adjust higher. The LC is setup for 91. Running the LC on lower is not recommended unless a one off until you get premium.
I know this opens up a big can and its been discussed in many other threads.
As for the OP, comments. I...
Are you using a fuel additive like Chevron's Complete Fuel System Cleaner? I know the 4R is Direct and port injected which should reduce build up but do we need to use an additive like the one linked below...
