Preventative Maintenance before a 2,000 miles roadtrip with a 507,000 mile V8 4Runner

[pcos55]

Toyota's normal build spec is a 15-year service life with normal usage. That said, the Land Cruiser is built to a 25-year service life w/ offroad usage.

Complete hearsay, Toyota has never put out those numbers.

Pcos55,
I normally am not as worried but with this high of a mileage I am doing my best to hedge my bets. I cannot recall where I read it but Toyota designed trucks for a 20 year lifespan before major overhauls. Given my high mileage on a 13 year old truck I was looking for helpful opinions.

Again more hearsay. Toyota would never put out lifespan numbers because they have no relevance. They don't come with an expiration date. There are plenty of perfectly running 20, 30, 40 year old Toyotas out there with mostly original parts.

My helpful opinion is to stop wasting your money on parts that aren't needed. These trucks will last until either they're totaled, run without fluids, or rust turns them frame to dust.

My 2008 SE V8 4Runner has 507,000 miles and the original drivetrain. I am going through everything in preparation for a 2000 mile trip from Los Angeles to Glacier National Park in Montana.

Here's a list of what I have done and if I'm missing something major please chime in. Within the last year I have done the following:

Denso spark plugs and inspected coils
All new coolant hoses, fan clutch, thermostat, and new red fluid.
Timing Belt done 2 years ago at 483,000 miles
JBA UCAs with new bushings and Moog ball joints.
LCA new ball joints and bushings.
Aftermarket CV axles and new cv axle differential seals and new fluid.
All new sway bar bushigns and links.
new oem air filter and cabin filter
new power steering (toyota atf) fluid and used GX470 pump from parts yard
All new OEM Toyota brake lines except two custom extended lines and DOT 3 fluid.
Powerstop front pads and rotors
Durobump stops
Inner and Outer Tie Rod ends
Cam tab gussets
Spindle Gussets
PML High capacity transmission pan and new Toyota WS fluid
Talon's Garage 1/4" thick aluminum transmission skid plate (on order)
OME medium 2895 rear coils
New Autozone gold battery
rear trailing arm skids

Things I want to do before I go:
rear diff fluid swap

I carry a tire patch kit and air compressor at all times plus a self jumping battery. Then the usual assorted tools.

I didn't see anything regarding the transmission fluid. Have you changed it ever? I know that the manual states "lifetime" transmission fluid, but the word "lifetime" is defined as 7 years in California.

With the new pan, how are you checking the fluid level to insure it has the correct amount?

These will bolt on and the bearing is in there. Amazon.com : bearing assembly for 4runner

500k+ on a '08 is nuts. I only have 86k lol.

Glad to hear shes still going strong!

 

[bob3dsf]

My 08 has only 115K ...

Oh, to back in the 100's.... Like a brand new car! LOL

Back in my day, blowing a tranny meant you had car trouble.

 

[joec500]

From my research on toyota trucks it seems if maintenance is followed and you don't live in an area with a lot of snow/salted roads, these cars can run 500k miles pretty easily.

My other car is a Porsche 911 and older 996 turbos are hitting 300k miles on original motors and trannies. The owner stayed on top of all maintenance obviously, but those cars are also built bullet proof. Maintenance goes a loooong way.

 

[gloch]

This is an inspiration for me. I just ticked off 250k on my '03 V8. Your list of maintenance items is extensive and represents goals for me. Did you do these yourself?

 

[Monty87ls]

If it was me Id change the oil before the trip of it wasn't done recently. I also tend to add some lucas in mine. 04 Sport with 108,800 as of getting home today.

I pack on some miles but I doubt mine will ever reach that high of mileage

Have you ever had to replace the starter motor? As I suspect you know, they are buried under the intake manifold and a real pain to replace on the V8.

 

[randy88fj62]

Hello everyone,
Wanted to give a final update on this thread. Over 513,000 miles after the trip and did not have any issues. Purred the whole way up without a single issue.

Only failure was a fog lamp bulb on the arb.

To answer a few of the questions since I last posted. I do all my own maintenance and upgrades. I find I care more than a mechanic that gets paid on commission for how fast a job is done.

Regarding the starter. I am not sure when that was replaced as I did not see that on the toyota list of replaced parts. Not a big deal as it can't be as hard as the exhaust manifold.
