Jeep Wrangler



  • If I remember correctly, most everyone has indicated that the best mpg that I could expect would be in the 15-18 range for most driving. I live in Northern VA area around Wash DC and the traffic can be less than fun!

    Since I have recently bought my 00 Wrangler and it was designated as my 'weekend play toy', I don't intend to make it my primary vehicle. However, I am wondering what I could expect to get in terms of fuel usage. Any ideas? The first tank I tested got right at 17 mpg given the fact that drove it as a 'daily commuter' for the first week.

    Thanks all - Chuck

    Right now I'm in the '98 Sport somewhere around Jean, NV on our way home. We decided to take the Sport since it gets better gas mileage than the Unlimited and we've been tossing around the idea of driving it more often on week days - these gas prices are killing us. Which brings me to a question -

    Can you put an OEM radio from an '04 into a '98? The Sport has the basic radio and no sound bar, so I was thinking of getting an aftermarket soundbar and installing the OEM radio we took out of the Unlimited. It has an aux jack so I could hook up the Roady directly to the radio, instead of using the FM modulator (too many stations in Los Angeles interfere with it). I figured that adding the soundbar and re-doing the wiring would probably be necessary if I did this.

    Or would it be cheaper to change the head to an XM ready radio and plug the Roady into that, leaving the radio speaker configuration alone. I'd like the soundbar and I thought it might not be too expensive if I used the radio I already have. However, if I have to get a new radio I'll skip the soundbar.

    Any economical suggestions?

    As far as MPG - so much depends on your personal driving habits and conditions. I routinely get 18 plus mpg on our commute (150 miles per day, 98% highway with a mix of slow and go and 65 mph involving about 6,000 feet elevation change) in the auto Unlimited, and around 20 in the '98 manual Sport. The one all city driving tank I had in the Unlimited was around 14 mpg. A couple of days ago when i was struggling through the backup from a major accident our mileage (it took us an extra hour and a half to get home) we got 17 mpg.

    I can't see any problem in fitting an aftermarket soundbar and wiring things to suit, and I certainly wouldn't go to the expense of a new head unit just to connect it to the original basic speakers. However, you may have make some alterations to the dash, as the early head unit had square corners but the latest ones are more rounded.

    Variables to consider are:

    Accuracy of the odometer (check with a GPS)

    Fuel quantity used. You can't judge by the gauge, nor by when the gas station pump shuts off (I get an extra 2.5 gallons after that point). You must either keep track of gas used over several thousand miles, or fill to the neck each time.

    Will you be offroading? Off road use will dramatically increase your consumption in mpg terms.

    Auto or manual? Figure about 2-3mpg difference.

    Will you use a/c? 1-2mpg on a 4.0.

    Will you get it fully warmed up, or just make short trips?

    Will you drive more 'enthusiastically' now it's a weekend toy?

    You really can't do more that 'guestimate' your consumption from one tank, but if you did get 17mpg commuting that's truly excellent. I get an average of 14mpg from my '99 auto.............never less than 13, never more than 15............but with the original optimistic speedo gear I'd be getting 16-17! :surprise:
  • what year wrangler? on a 1998, you pop off the vent trim on top of dash,remove 2 screws on top off center radio pod cover,and pop off the cover. remove 4 screws to pull the climate control out. there are two bulbs, one on the left top, and one on the right side. good luck getting the right bulbs from the dealer!

    I do not count the time it takes me to run through the car wash, since I would have the Jeep washed anyway.

    I built a hoist system with a crank to remove and replace the top, so that does not take me much time at all. The top hangs on the hoist in the garage when it is not on the jeep

    When I remove the soft top I do the following:

    1. I lay out a piece cloth on the drive way.
    2. I remove the rear window and place it on top of the cloth.
    3. I place another piece of cloth on top of the rear window.
    4. I remove a side window and place it on top of the rear window.
    5. I then place cloth on top of the side window.
    6. I remove the other side window and lay it on top of the side window.
    7. I place cloth on top and roll up all three windows, and then wrap the roll with a cover.
    8. Then I lower the top and wrap it with a cover.
    9. Unscrew the four screws that hold it on (thumb screws) pull it off and hand up in the garage.
    10. Pull the door surrounds off and put them on a shelf.
    11. Put a bolt threw the radio mount bar, holding it to the roll cage.
    12. Finally, I back the Jeep up under the hard top, lower the top and tighten it down.

    It could take me as much as 30 to 40 minutes in stead of the 20 minutes I originally quoted to reverse it and put the soft top on, I did not time it. However, I know it does not take me long to swap tops. I have done it many times. A few times I did twice in a week because of the weather or security concerns.

    I am sure I am not as meticulous as you are. I put as much care as I can to preserve the windows, but I do not worry about dust getting through to the top.

    I'm kinda glad I bought my soft top used and pre-scratched :P

    Don't get me wrong, I take pretty good care of my Jeep. I just dont go to the lengths of everyone else, on this board, when it comes to the soft top windows.
    The little bit of dust that collects during the winter comes right off in the spring.

  • My wife has wanted a Jeep for the past several years and finally got one in the spring of 2004, after retiring. We both love it, but haven't gotten to the point of hugging it every day. We purchased a 4L, six cylinder, 2004 Sport with an automatic transmission. We also have a 16 foot fiberglass Scamp travel trailer that weighs 1500 lbs. dry. The Scamp has electric brakes. We have traveled extensively with the trailer, but pull it with a Ford F150 pick-up. We never imagined that we could pull our little Scamp with the Jeep until we saw some people in Colorado pulling a heavier travel trailer with their Jeep. Realizing the 2000 lb. maximum rule for Jeep Wrangler's, I would like some information on towing my trailer.

    1. Would the Jeep have enough power to negotiate mountain roads? Being old and retired, we are never in a hurry (don't you just love those drivers) so slow is ok.
    2. I know I would need a class 3 hitch and a tranny cooler with filter kit, but is there anything else I would need?
    3. Are we crazy for even exploring this possibility?

    Any information anyone might have on this topic would be greatly appreciate.
  • mac24mac24 Posts: 3,910
    Your Jeep is more than capable of both pulling and stopping your trailer. The 2000lb restriction is due to the relatively short wheelbase which would allow it to become unstable more easily when being pushed by a heavier trailer, as in descending a steep hill or snaking on the flat.

    So, 1: Yes, plenty of power, just use reasonable caution when coming down those mountains in the rain. Remember also that in high winds the large surface area of the trailer will have a disproportionate effect on your Jeep, so keep it slow.

    2: The tranny cooler and filter are very important, and the filter adapter will allow you to easily fit a transmission temperature gauge. Be sure to fit it on the flow line to the cooler rather than the return. Also, fit the aftermarket cooler after the factory one. Additionally, you should use synthetic or semi-synthetic oil in the diffs, as recommended by Jeep.

    3: No, just don't forget have a trailer behind you, and pull over from time to time let the line of traffic behind you go past. :)
  • hey hey,

    the actual connectors between the radio and the wiring harness are different between a 1998 and a 2004. mopar does make an adapter, so this shouldn't be an issue. really the only other part you will need is the center bezel itself, which you can get cheap on ebay (it attaches the same way as pre-03 bezels). otherwise, all screw holes are the same. good luck!! :shades:

    This morning my other half filled up the Sport and figured we got well over 21 mpg on the last tank. However, don't take this one too seriously - we drove from the house (about 6,000 feet) to work (sea level), then up to 4,000 feet (Lebec) where we found a landslide had blocked the one road into our area. After spending an hour eating dinner we gave up and drove back "down the hill" to spend the night at friends (about 1500 feet) and then on to work (sea level - total distance 226 miles), for significantly more downhill driving than uphill driving. Sure wish I could count on that figure all the time!

    This confirms what we had always thought, the Sport does get about 2 mpg more than the Unlimited.

    Now we're thinking about adding the sport bar and a new radio - it isn't all that much to add a third unit to our XM account, and my other half hates having wires that have to detached and re-attached all the time. He knows I'm not about to give up listening to the Roady at the office. And if we don't get a top of the line head unit, I think we could do it for about what we spent on the Unlimited's Alpine head that had the XM tuner built in. Does anyone have any thoughts about where to mount an XM tuner, now that the new ones seem to be much smaller than the old ones? I was thinking that there might be room behind the dash, rather than mounting one under the seat (the Sport has been known to leak but not recently).

    When I did the XM stuff for my Wrangler back in January, I mounted the antenna box on the sidewall right next to the passenger feet area. The Alpine connecter (This was a universal one from XM) I stuck above the glove box to the bottom of the airbag box/holder. That then ran to the Alpine HU.

    Why don't you just get another integrated XM Alpine tuner? :)

  • Thanks Mac for the most useful information. I will ready my Jeep this winter for a long trip to Alaska in June. I will try to find a good mechanic in Phoenix to follow your detailed instructions.
  • keatskeats Posts: 412
    I agree. If you're going to get a new head unit, get one like the Alpine with the XM tuner already in it.
  • mtngalmtngal Posts: 1,911
    The main reason why I'm thinking of not going that way is that it's more expensive, and since I'm looking at a new water heater (for the house), dental work on the tooth I broke yesterday and roof repairs (we have big leak), my available finances aren't very large. Besides, we're talking about a 7 year old vehicle and I'd hate to put a bunch of money into it, only to sell it in a year. Not that I'm planning on selling it any time soon...
  • Hey Keats. My top is still off and I am enjoying some nice weather after all that miserable rain. I got the end caps and put them on. Nice look and much better for off road. Nothing gets hung up in them. Thanks for the tip. How's life? Go Easy, KB2
  • Well...thinking my leak after 5 inches of rain, was coming through the vent on the cowl, turned out to be wrong. The service dept determined the leak was from a faulty gasket under the folding windshield from the factory. Of course the dealer did not have this in stock and another 70 mile return trip is in the cards. Oh well...only more expensive gas and time. Anyone else ever experienced this?

    I have this Pioneer and am happy with it.

    You can control XM or Sirius with this head unit. I haven't subscribed to satelite yet, so I can't really give a review on how well it controls the satelite info. It's $250 on Crutchfield. Not sure how that compares to the Alpine. I'm guessing it would be another $100 to add the XM modulator. just a thought :)

    Yep. Just replaced the cowl seal on my 95 Rio Grande. Pain in the you-know-what. It looks like the TJ cowl seal are easier to replace as they don't have a vertical lip on the exterior that needs to be attached with weatherstripping adhesive. That process is a pain. Look at a YJ and you may understand. Otherwise, it is not a difficult job at all.
