I hope this get sticked....
Things To Look For when buying a jeep wrangler YJ:
1. body damage, tap around the jeep logo and the fenders for bondo.
2. Check for rust, Under carpet, floormates, by drain plugs the side wall inside where the jeep logo is, the engine compartment under the master brake cylinder, shock mounts, axel mounts, gas tank rust, wheel wells, tranny cross member and the bottom of the frame.
3. Make sure all doors seal, open, and close properly from both sides (yes i said both sides).
Check under the dash for water markes, as the fire wall and windshield are know for leaking.
4. Check the fluid levels.
5. Check the battery for corrosin
6. Make sure the horn, key, and steering wheel all work right.
7. Make sure you have all the proper keys, Door's half/full, the glove compartment, back tail gate, lock box's, Wheel lug lock keys, wench start key, ect.
8. Tops Learn how to take it off if its a soft top have them show and check for missing parts.
check the back windsheild struts, check the fiberglass for cracks, the bolt holes for wear, and that there is a seal bettween the body and top.
Check for day light, Rips, Stiches coming out, are the windows clear and free of scratches or foggy? can you un-zip and re-zip the windows and the zipper is not off track. Are the button clips okay, and are the side plastic door/front windshield mounts cracked?
9. Dose all the enternal electronics work. Radio, lights, cigarret lighter/12v aux power, fan, heater, vent cable opens easily?
10. Petal's fell okay clutch esp.
11. Check the roll cage and windshield to see if the vehical was ever rolled.
12. inspect the differantal's, oil pan, axels to see if they liked to rock crawl.
13. Inspect the window frame and the seal's for age, crack's, or rust.
14. Look at the tire tread and there side walls for off roading wear.
15. Check the exhuast system for rust, leaks, hole's, dent's, ect.
(I got my buddy a jeep real cheap because the lady selling it thought there was something wrong with the engine. really one of the U-bolts had came lose and it had an exhuast leak. so it was idleing ruff, sounded bad, and had trouble starting due to bad back pressure. He got it for a steal and all we had to fix was a u-bolt LOL)
16. Brake and hydrolic lines for dents
17. Walk around it again and wiggle everything. listen for noise's feel for movment, ect
Test drive it, Run threw every gear at every RPM range, test the low and high 4X4, brake hard from 60mph, turn on all the lights and brights, make turns in 4X4-normal juttering is expected on a 90 degreee turn.
Last but not least piss on it, to mark it as your's if you like it.
List of Items that should of been replaced on NHTSA recall:
Im lazy just read the list here. LIST
Things I learned To Replace on a Used Jeep:
Passenger Side engine mount. replace it with Dealership part as its much stronger and better metal then auto parts store. There known to break.
You'll drop your engine, your fan will fall, hit the axel and get bent, the oil filter explode when hitting the frame, It might rip out your front tranny cross member bolt on the passanger side or weaken it so it rust out faster, the Oil Pan will get dent, and you'll have to tow it home or macgyver it.
Its a good idea as it may have cracks, clogs, holes, and you can get an oversided one which will add more cooling. Save your self from haveing to buy a new engine becasue you over heat it.
Cold Air Intake
: it will run so much better, its not even funny how much you will notice it. The stock air box kills your flow, NOTE: keep the air box for if you state has emissions test.
All Fluid's, this is a no brainer. If i was going to buy a car i would ask to test drive it over night. and i would take it home and check all the fluids and crack the rear diff. to look at the the drive line input bearing and at the Ring and pinion gear to see how messed up they are.
U joints all of them.
they can wear and cause vibriation, witch will kill your seals and your diff. bearings.
If they look like shit put new one's in. and i know they do they have rips and are mostlikely yellow. perferably ones that recline and arent made of ball sweating materail as jeeps are and should be natural AC. Also the standerd seat brackets rust and the seats internail support's fail. And later on you woun't have money to. Jeep Just empty every Pocket you will always want something cooler then seats, tires, lift, speakers that you won't beable to hear any way, ect.
Alot or all of the wiring, hose, and vac. lines.
you will save alot of time and money buy finding problems before they happen by checking your lines. Most batter cable lines will be corroided, you will find atlest one hose with a crack, hole, or rub in it, vacume lines its good to check with a pressure test so much of the jeep running correctly depends on your vacume lines. AND THERE SO CHEAP TO REPLACE ON YOUR OWN.
The stock carpet or any for that fact.
Carpet keeps water longer, it will causes rust, and your jeep has leaks face it. Also it smells bad, oil, grease, food, water, ect so just pitch it. i only have the floor pans and mats in my jeep i threw away the drain plugs too, as i tend leave my jeep topless in the rain. I recommend rinio liner or bed liner for your jeep. put it everywhere.
If its not rusted yet, RTV the F**K out of it. you'll thank me later.
Just a good idea new brake lines are cheap and if your jeep has lift you might need longer one's. and the pads need new just so you know what you have. If you take it to a shop check the torque on the wheel nuts as they alway over tighten them with impact wrenches.
Things you might want to up grade.
On a 2.5 up grade to the 4.0 Throttle body.
hard top or soft
If i forgot something plz add it in a post.
