I think I wanna do a tune up I know plugs are first. And air filter. But anything else? I've done both diffs. Xfer case and tranny. oil change is almost due. Ill be rotating tires same time as oil change. It's running perfect just want to do some pm. U joints are also new. Just want it to be tip top.
You know that's almost an open ended request. Anything that moves , turns, or flexes should be checked. But to be just a little more specific here's what I went over on my "new" 05 I got a couple of months ago.
Plugs, belts, coolant (flush and refill with 50/50 mix), diff lube, X-fer case lube, tranny fluid and filter (mine is an auto), air filter, shocks and steering stabilizer, radiator hoses, thermostat, fuel filter, oil and oil filter. (Also replaced heater control panel, speed resistor and fan blower motor but that was really more of a repair.)
Pulled both drive shafts and checked u-joints (looked for dry or stiff movement as well as too loose), checked front axle ball joints (no play), checked axle u-joints , checked the brake fluid (probably should flush and replace), checked brake pad and shoe wear as well as rotor thickness and drum wear, adjusted rear shoes (had one side kinda loose), checked bottom of water pump for any leakage, had front end alignment checked, pulled the skid plate and checked the tranny mount...(cleaned and coated the skid pan with truck bed liner), this list can go on forever but you probably get the idea by now...
The basic idea is to give your jeep a serious eyeball and address annoyances now before they become a trail breakdown later..
Horse: the original off road rig.
Jeep: just as fun and no stall to muck.
A little more backstory might be in order. Bought it almost 2 years ago with 100,000 miles. Runs great no oil leaks, clean, minimal rust(Michigan salty winter), and all stock beside 235/75/15. I have been taking care of her and making sure I fix any problems that arise. I just hit 150,000 miles and all is good but I figured a little TLC is in order in her old age. I do have a tic when cold but I hear it's normal and is not a problem. That was from a off-road jeep shop near Fenton mi. Any little ideas or a list of things that I should replace or repair.
