Had this XJ in the family for ever now, has been maintained primarily by my dad, brother and I. Recently replaced the tranny fluid, regular oil changes, has an injector swap... but it's "mine now" and i'm not sure where to start to keep it running strong.

Thinking of replacing my TPS because of strange shift patterns that i've known for quite some time now.. other than that i'm not all too sure.

service both diffs and the t-case. Do a rear main soon. Wash everything underneath down and check for any leaks after a few days.

What Evers broken or not functioning properly along with a fresh batch of fluids to prevent the latter

241k huh, another 55-60k and it'll be time for its 3rd oil change. Lol but seriously, I'd go ahead and service the transfer case and change the diff oil and take a good look at the gears and make sure there isn't an abnormal amount of metal flakes in the fluid, but aside from that if it ain't broke don't fix it.

Full fluids (drain and refill on the trans, no flush), filters (air, oil, and fuel), spark plugs, distro cap, distro rotor, wires, fuses, bulbs, windshield wipers, serp belt. Any of the small stuff just so you at least know when it was done last.

...all of your other vehicles with XJs.

I agree diff fluid definitely do diff fluid. And tcase.

Tune up if there hasn't been one in a while. Flush the coolant system out. 02 sensors. Clean the TB and its sensors. Drain and refill brake fluid. Power steering fluid. Ahh the possibilities.

But I wouldn't change any major parts (especially expensive sensors) if all is well.

What fluids do you recommend for high mileage like mine? (t-case and diffs specifically)
