Ok so The 01 XJ is about to turn over 100K and i was wondering if there where any recomdations of matince. the plan is to

Inspect:
Coolent, raditor hoses, brake fluid.

Replace:
Transmission fluid and filter, Oil, serpentine belt, dif fluid, Change out to Neon injectors, and check the fuel filter.

So is there anything else i should look at or replace?

O and even though I looked them over and took them to a shop my breaks squeak BAD, any advice when there appears to be nothing wrong?

 

Squeeling brakes is a sign that the pads are worn and need to be replaced. I'd add that to the list as well.

Also, when was the last time you changed the spark plugs? For your 01, I'd consider replacing the plugs with some NGK Coppers gapped to .035.

Also, take a look at your air filter to make sure it's in good shape

 

BTW just in case you did not know, your fuel filter is in your gas tank. It also would not be a bad idea to check your control arm bushings and replace if they are cracked and funky.

 

We don't know the history of maintenance on this vehicle. 100k doesn't mean much, it's when was the LAST maintenance performed.

All fluids, (coolant, transfer case, transmission, differentials) fresh NGK plugs, new air filter, new 195 degree thermostat purchased from Jeep, replace all hoses if original; you are on borrowed time with 11 year old hoses. Inspect or replace serpentine belt; I go 60k on my serpentine belts.

As mentioned, the fuel filter is part of the fuel pump "assembly", which is located inside of the gas tank. No need to worry about it unless symptoms or testing point to it.
