30k check list

[rchung813]

I've put together a 30,000 miles check list of items to maintain for my KJ. It's a mixture of what is listed on the manual and what others here have stated in the past. What do you think and am I missing anything? Is this overkill?

1. Change the engine oil and engine oil filter, if not replaced at 3 months.
2. Rotate the tires.
3. Inspect the engine air filter element, replace if necessary.
4. Inspect the PCV Valve, and replace if necessary.
5. Replace the spark plugs.
6. Inspect the brake linings.
7. Drain and refill the front and rear axle fluid (diff). (75W90)
8. Flush Brake Fluid [if you want or as required] (DOT 3 or DOT 4)
9. Engine Flush
10. Check tire alignment
11. Transmission Flush Fluid (ATF+4) - (Want the filters changed; Drop pan.)
12. Fuel system clean up w/ replace plugs (seafoam?) or throttle body cleaning is also part of a 3 part professional cleaning
13. Transfer Case Fluid Change (ATF+4)

30k list

Overall good list of things to keep it in top shape.
I would add a power steering flush.
Add exhaust and Complete suspension inspection including ball joints and alignment.
Ensure that the air filter gets replaced with air box cleaned/spotless.
Check the battery fluid if applicable, and add distilled water as necessary.
Inspect windshield wiper /clean blade with alcohol and replace if necessary.
Ensure all lights are in working order.
Test antifreeze for temperature reading.

Don't think that seafoam in the intake is needed at 30K miles. It's only my opinion but I did a seafoam at 60K and didn't get very much smoke burn off. That lead me to believe that there must not be much carbon build up on the intake side of things. Now fuel line and crank case could be different. [As always this depends heavily on driving conditions]

Change the PCV at 30K. There isn't any need to inspect it.

Grease the sway bar bushings with a silicone lube.

Ahh yes a few more items to add especially:

Changing / cleaning of the air filter
Suspension inspection including ball joints and alignment

Is a Power Steering flush and change of PVC really needed at 30k? How often should each of these items be maintained?

Change the PVC valve at least every 30k,it's only $5 at Napa.The P/S fluid is the 2nd most neglected fluid in a vehicle(brake fluid is the 1st),might as well change it,your R&P and pump will like you.Be sure to do a fuel induction cleaning at least once a year(no matter the mileage),does wonders.

Thanks tjkj -- additions to my valuable list.

Change PCV value
P/S fluids
brake fluids

The fuel induction cleaning is the same as a "3 step fuel system service"?

Not Troy, but yes, essentially

What is a fuel induction cleaning? Something I can do or must I bring it to a shop?

A fuel induction cleaning is a 3 part system.

The 1st part is a cleaner that is sucked into a vacuum port right into the intake plenum while it is running.The 2nd part is a throttle body/carb cleaning,done while the engine is running also.The 3rd part is a cleaner that is poured into the gas tank to clean out the insides of the injectors.

You can do this at home yourself with a product like Seafoam and others.


Just use caution as improper application can cause serious damage to your engine.Do not use any type of fuel injection cleaner more then once a year in your vehicle as they will destroy your cats if over used(that includes the stuff you jsut pour into your gas tank).
