hi i was wondering if i could get some help, i just bought a 1987 comanche 4x4 5spd 4.0 I6 with about 118k miles on it. i got it for 300$ but it has been sitting for 5 or so years i was curious what should i do to it or change in it to make it a daily driver for winter thats comming up. thank you for any help i can get.
Does it run? Does the 4x4 work? Do all the lights work? Wipers?
Without pretty detailed information, it's hard to give advice.
I'll start with basics.
1. Sign up over at comancheclub.com. The best internet site for these trucks.
2. Change oil, filter, antifreeze. Check for oil leaks. There are probably several. Check for leaks in the cooling system.
3. Check for clutch hydraulic leakage around the slave cylinder (bellhousing)and master cylinder(under dash close to fuse box). That's a common place for it to leak.
4. Tune up, plugs, wires, filters, rotor and cap.
5. Check the brakes for wear and check the fluid.
6. Check your floorboard under the carpet for rust and holes. Common on these trucks.
7. Check the belt and replace as needed.
There are a million things to check over, but that is a good start.
Nice find! I found a 88 2WD 4.0 with 5 speed. Cool little trucks I think. Change all fluids! It's always a good thing to do, especially if you don't know old they are. Drain the old gas and clean tank if dirty. Replace fuel filter. Tune up and air filter. Mine needed tires. Still needs lots of love.... Check all your suspension and brakes. Lube everything that needs it. Then slowly bring your mj back to show condition : )
i havent checked the frame yet i was planning on going over to my uncles later in the week to pull in onto his pavement to see how bad the frame is. hopefully not bad if not it will make a great truck for 300$ plus whatever i put into it to get it roadworthy.
frame is great hte truck was originally from alabama, so there is very little rust other that the drivers side floor board i noticed is rusted out, the passanger side doesnt seem to be to bad, the brakes im not so sure about i opened the break booter there was no fluid just what looked like clear gunk. i also want to change all the fluids like the diffs and tranny and t-case what kind of fluid and how much roughly would i need to do each, please and thank you. i do reemember my uncle saying that the back breaks don't work he said new drums and shoes but still dont work, could that just be no fluid at all in there or something more?
Change the fluid and bleed the system. If the rears still don't work, it could be the proportioning vavle or the wheel cylinders.
Wheel cylinders aren't expensive. Can get them at any auto parts store.
Axles use gear oil.
Transfer case if a NP231 should use auto tranny fluid.
If tranny is an AX15 it would take gear oil as well. If I remember correctly.
I don't remember how much.
finally got to tinker with the jeep the other day and was very happy to find out that all i need to do to it after it sitting for 5+ years was put a new battery in it and it then started right up and within a few minutes she was idiling on her own, granted it wasn't all that smooth but after sitting for so long it was smooth enough.
