Just got an 02 - Sport - Lots of questions

sorry but i'm new to the jeep thing. have wanted one for about ten year now and finaly got my first one. Well here is the history behind it. 2002 Sport 6 cyc auto transmission, 51000 miles, soft top. bought the car a month ago with a salvage title. jeep had an electrical fire. bought the car from a salvage yard in kentuky, the guy told me he replaced all the harnesses. We'll here are some of the things that don't work some are related to the fire some not.

1. Horn does not work. repalced horn, clock spring, switch/air bag cover, relay, fuses. and still no luck.

2. I have a leak in the steering gear box, can that be fixed or does it need replacement.

3. 4wd lights do not turn on on the dash when 4wd engaged.

4. slight rough idle more noticeable when first turn on. replaced plugs with delta jeep plugs, new air filter.

5. water noticed in tub behind drivers seat, no idea where it's coming from.

6. i have center counle with sub enclosure, don't hear or feel the sub, can the subwofer be replaced and still used if i replace the head unit with aftermarket. and only my passenger side front speaker fully works, drivers side front just crackle,drivers side rear just crackle, passenger side rear works but crackels, would new two ways all around sound good with the top down.

7. when stoped at light or traffic as i release the bracke and begin to apply the gas i hear slight poping in passenger side front. not always but enough.

8. want to replace my 30x9.5x15 goodyear gsa with 31x10.5x15 gy mt/r any comments.

i think this is it for know. sorry if it any of this sounds stupid but i'm new at the jeep thing. i am the kind of guy that tries to fix things on his own until i'm really stumped then i'll call my mechanic. so i would like to troubeshoot alot of these issues. any help would be great.

well i dont have an answer to all of them, only a few, but here goes...

First i had the same thing happen with my 4wd light...the 4wd engaged, but the light in the dash didnt come on. I replaced the sensor on the t-case and it works perfect now, so im pretty sure if you can locate and replace that sensor it'll work again.

Second, this is just a guess, but the water could be coming in due to a bad seal on the soft top somewhere or around the driver door. Maybe you could hose down your jeep and check it out to see where its coming from? Not exactly sure on this one, its just a guess.

Third, if you want to improve your sound system i recomend just replacing all of your speakers with aftermarket ones and getting a good quality aftermarket head unit. Also, an external amp isnt an absolute nessesity, but it would make your new speakers sound even better. It sounds as if you're speakers are worn out or damaged so replacing them would probably be the best option.

Fourth replacing the 30 inch gsa's with 31 inch mtr's will improve your offroad ability as well as the looks of your jeep. Keep in mind though that with larger tires comes somewhat slower accelleration and reduced gas mileage. The mtr's are a good tire, the ride will be a little rougher than the ride from the gsa's but no too bad. If you're planning on installing the 31's without a lift you might experience some rubbing at full turn on the control arms, especially with aggressive tread tires such as the mtr's. The rub shouldnt be too bad, but it might be there, so just be aware. Installing a 2" lift will eliminate the rubbing problem but will also add to the cost of the upgrade.

Good luck and congrats on the purchase of your jeep, you're gonna love it!

Take a meter and chase electrical breaks in the systems.When you have electrical problems a meter is your best friend.

for the rough idle i would get some "carb" or fuel injector cleaner and put that in the gas, if that doesnt work, then you probabaly want to clean out the air sensors and buy somespray for that and spay it on the sensors

as for the water i would look for the hose that drains the cowel, it may be blocked up and then the water would seep into the passenger compartment this is a very common problem

and next i dont think that you wil have any rpoblme rubbing, and if you do a lift wil not help, there are two things that can rub, if you rub your fenders at flex you need lift, if you rub your control arms while turning, you need wheel spacers, skinnier tires, or new wheels with less backspacing, most people get these wiht 4.0 in of backspacing
but with 10.5's i dont think you will rub your CA's

lastly you can get lots o faftermarket speakers and thing to go in a jeep, and the amp should be able to hook up to all of them

It is my understanding that the reduced gas mileage with larger tires is a myth. Unless you recalibrate your speedo gears, your speedometer is underclocking your speed and distance traveled. Therefore if you rely solely on your odometer, your recorded distance traveled will be under recorded.
