First thing to do is ensure all the transmission oil levels are correct. It is a good idea to draw a little oil into a sight glass to check the condition. Check the condition and security of of the propshafts and universal joints and a thorough wheelfree inspection of the underside. It is perhaps worth noting the gearbox rotates considerably faster than road speed. A road speed ticking is unlikely to be directly related to the gearbox. The only things that do rotate at road or wheel speed are the wheels and things connected directly to them - brake rotors, drive shafts/half shafts, differentials...

Have you checked the clutch master cylinder fluid level?

You don't need a scanner. If you cycle the key off and on 5 times, the codes will start flashing. Here is a link to jeeps and their trouble codes. There aren't that many in the older OBD-1 systems. https://www.2carpros.com/articles/retrieve-trouble-codes-for-chrysler-dodge-plymouth-odb1-1995-and-earlier-car-mini-van-and-light-trucks If you have no trouble codes, check fuel pressure. Multiport injection is high pressure, above 40psi, but Jeep would have specs.

not normally there may be metal flakes in the filter in the reservoir so replacing it would be a good idea don't bother repairing the pump, it will be more cost effective to get a new one if short of cash , get a good unit from the wreckers/ junk yard

first off we can hear it , see or or drive it, so... answer will tend to be useless, on NOISE why not find source of the noise first. so it does it parked with brakes on, making the source(Location) 10x more easy and 100x more safe to find. no? why not demo it to shop, and bingo, found. all in minutes they open the hood and hear the fan belts sing, they are bad. but can be something loose. (id say too ,not the trans) when you shift, do say drive, the engine twists, and trans and all drive shifts engaged, (rear) 2wd. so any of that can make noise, even a loose mount. and more lots more. find a real mechanic, ASE shop and not stealerships, that want to sell you a new trans for $3000 a good shop has an electronic stethoscope, that can find locations 99% of the time. (not u-joints do to they spin and make noise then mostly) the stealershop is too busy to test, they stack money, only there.

it appears from your description that it is a clutch operation problem in that it is not disengaging properly to allow the clean selection of first gear that amounts to air in the hydraulic system, faulty slave cylinder or faulty clutch master cylinder unless you have oil on the clutch plate causing it to stick or a dry or seizing spigot bearing in the flywheel( possible ), there is no report from you about a clutch problem( slipping , shudder smelling hot) At this point replacing both the slave cylinder and clutch master cylinder would be the fix especially if they have not been serviced since manufacture take it to an accredited brake /clutch specialist shop for diagnosis /quote some vehicles have the slave cylinder internal in the bell housing (very bad and repair costly manufacturing idea) and if that is your case , the transmission will have to be removed to replace it should that happen and as the box will be out , it will be cost effective to inspect the clutch at that time

I hate to tell you this but... If it overheated you probably have at the very least blown a head gasket. The best thing to do is run a compression check and that will tell all. Hope that helps

2.4L so did you first idle it to get over heat,220f so it can kickon, scanning the ECT s,proving it hit too hot,, per SM>?? the key here is what, a real schematic, and a simple voltmeter some jeeps also have a modulated fan.(and driver for it) fuse 4, PDC good. tested? it goes to fan relay , contacts and then to fan motor circuit breaker no air pocket on top of engine,making, ECT lie? i the pcm sees ECT overheat it puts 12vdc across the fan relay coils if not the wire there bad,cut or pcm bad. the PCM pin C2-p17 LG wire goes to relay pin 4 he PCM grounds this pin (using a transistor) the relay closes, fan turns on.

richard is right what ever has happened after you played at being electrician Put it all back to standard then get advice as to how to do each part

Check fuses and relays

no year stated, 96 to 2003TJ unlimited runs to 2006, no year makes this hard. why do that.? where is my filter 2007 first year to go inside TANK Yours is on top of tank' covered in the book, posted here 300+ timesTJ chapter 14, read it,it has words, telling what to do.http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service 2006 unlimited, 2.4Lis hereits 2 parts in 1, filer and FPR

check fuel filter and also check if O2 sensors are working on exhaust

Double check that everything is reconnected properly

take it to an accredited suspension center as it appears that there is a problem with suspension mounts and wheel alignment

There is no external inline fuel filter, no manufacturer uses them anymore. There is a nylon fine mesh screen on the inlet to the electric fuel pump, it never needs to be serviced unless the fuel pump is being replaced. Most often even then you just wash it out in Stoddard solvent

jeeps are chrysler and use the same components as the others of the range what you are familiar with in other makes is the same expectations in the jeep run the fault codes to determine the sensors that are not working

make sure that the inside of the rim is tight on the hub and not sitting off it loose/ incorrect wheel stud nuts will also cause the noise

its bad,the PDC no country stated, no engine stated,? why? the 2005 (answering for USA) PDC hard short all fuses, all breakers all relay out means what? well power distribution2 below shows all that, every wire there. ASD relay pulled? you never said relays, they can (weld closed inside contacts can)) and is unfused, this relay. fact i read the 22 pages for you there, its just fuses and relays, no magic until 2007 (TIPM electronics) this car is easy fix,. due to 2005 year. looking now , TJ unlimited it is. see the manual yet, see how this all works 2003 to 2006 year. chapter 8w shows wiring, and modules the rules. 8w, pdc 2, chapter see that here, its there, clear as day.' http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service

why not get a auto-electric shop to do what you cant do. why not? you want us web bunnies to teach electrics in this text box? really>? I can, but wont. not now, what is best is leave the cars, electrics alone. dont hack stock parts. better is a clean install of fogs also some states have laws on how fogs work, (logic based on headlamps or parking lamps) so .... i cant guess your state. a new fuse box or inline fuse a new relay, a new switch and wire it all so it cant catch fire. (that fuse does that) if you need a schematic for fogs, its generic and can be found 1,million hits on google

JK jeep, i have 08 and full docs. it wires to the PCM, same wire colors as you can see drawing dont work right in fixya. they get "crunched" badly" the EGR is PWM modulated, first is to clean in. the exhaust path must be good the EGR must not stick closed or open. p0405 means the pin on sensor part is stuck low. tell me in most cases, the valve is stuck closed. clean it is best first action. the monitor pin is at X, this tells the PCM where the EGR moved per PCM command. (called feedback) yours is hard stuck.
