    I've got the longer wheelbase Unlimiteds so I can't give you real-world advice on your specific model. However, I can attest to Wranglers in general are not known for their highway speed characteristics. I know test driving the regular wheelbase Wranglers seemed a bit more "choppy" at highway speeds than the Unlimiteds.

    Start by checking tire pressures on all four. New tires certainly would improve your ride/handling and you'd want to have an alignment done with new tires as well which may solve the issue. You also might see if your Jeep has stock suspension parts that are worn. If not stock, previous owner(s) may have changed them out or added a lift.

    Just wanted to give you a few simple thoughts...I'm certain more ideas from the real experts on this forum will get you straight 'n smoothed out. Happy Jeepin'.

    mac, did you have a typo on the 70mph revs? Based on the 65mph number, looks like 70mph should be about 2695rpm.

    While we are discussing rpm. A few weeks back there was a discussion about the valves not rotating until above 3000rpm. The rotating knocked carbon off which helped smooth running. Heck, with my 3 speed auto, 4.0, I doubt mine had ever been above 3000rpm. What is the recommendation here? Run up to 3200 or so for a short period every once in a while? How often? How long?

    I put mine low and ran it up for ten seconds or so. Plan to do it every couple of weeks. My TJ is a run around town car. Darn few road miles.

    Mine has a shake about 60 mph. At 63 it is gone. Doesn't do it at 70. I'm thinking it has something to do with the 33's I'm turning and their balance.

    TrXuS MT's are a PAIN to balance on a good day.

    No, the typo was on the speed. :P

    Should have been 2500rpm at 60mph. Just under 2300rpm at 55mph, 2700rpm at 65mph, and a little over 2900 at 70mph. All figures taken from the tach, so they're approximate.

    Referring back to the original mention of 4000rpm, that would equate to about 95mph. Quite achievable, and even a little more, but not recommended as a cruising speed.

    As for the engine rpm required for the valves to start rotating, I don't know the exact figure but the theory is correct. However, the benefit is the evening of wear on the valve faces and seats, rather than the removal of carbon. You don't have to engage low range, just put it in first or second (after the engine is fully warmed up) and accelerate up to 3500rpm or so, hold it for a few seconds then slip it into 'D'. Do that once a week and it should keep you ahead of the game.

    Martin,

    Thanks for the reply. I have been putting it in 1st gear, not low range. My bad on terminology. :blush:

    Boy, I didn't mean to cause offense about the 3-speed. I do remember thinking a 3-speed was unacceptable when I bought my current Jeep new in 1998. My YJ had the 3-speed auto and I hated it. I thought it was cheap of Chrysler and still do. They also had a 3-speed in the Neon if memory serves.

    I get close to 20mpg on the highway with my 4.0L, 3.73 differential, 30" BFG A/Ts. It seems to me if I ran in 4th gear only I'd run close to 3000rpms vs 2500rpms. I don't know. Good to know about revving it up now and again though.

    Jeeps aren't perfectly designed and I do think potential buyers should know when Chrysler has been less than perfect, as with sticking a no-OD auto in the Wrangler, or the whole exhaust manifold fiasco.

    ducks,

    No offense taken on the 3-spped auto. Many of us have been on this forum since the early days of the TJ. Mine is a 2000, so I missed the manifold problem. My little "crappy" deal was poking a little fun harking back to the discussions on this forum about the crappy 3-speed auto being so bad that those who had the 5-speed (I think) manual just could not understand how we could put up with them. You would have thought crappy was part of the official name. Well, I drove manuals for thirty years. The TJ was my retirement present to myself. I was just tired of shifting. I knew it was my around town wheels and the auto would get the job done. It has not given me any trouble.

    Most of the problem the stick shift guys had with the auto seemed to revolve around not having an overdrive. With the 3.07 dif's, you kind of live in overdrive all the time. A little slow off the line, ( even a little slower since I put 30's on it) but it gets me there.

    True, the manuals are probably more fun to drive. True, you have better control over engine speed and power for up hill climbs. True you can use the engine for down hill braking. Heck, I live in the Chicago area. We don't have hills you can't see over. In fact, most of our pot holes are deeper than our hills are high.

    No problem. :D

    No offense taken by me either. :)

    The three speed in the earlier YJs was the basic TF999 without a lock-up torque converter. Revs would have been higher and changes more frequent, so I can see where you're coming from.

    However, when it comes to the number of gears, less doesn't necessarily mean cheaper. Chrysler had some truly awful transmissions available that could have been used to bring an automatic to the Wrangler for the first time, but to their credit they picked a strong, heavy duty but smooth unit that was fully capable of handling off-road duties as well as those on.

    Remember as well, that the Wrangler is a true dual purpose vehicle. If its development had been directed purely at on-road driving then it would long ago have had a unitary body, smaller wheels, two wheel drive, independent suspension and a smaller higher revving engine.

    Virtually all the features on a Wrangler are a compromise of some sort, but right from the early days the vehicle has been in evolution, and continues to be so. The vehicle on which the current model is based was introduced over sixty years ago as an off-road military transport. The vehicle will never be perfect for all people, all the time, but I do think that the introduction of the Torqueflight 999 was the correct decision at that time. Especially considering the alternatives, which were either a much weaker four speed or no auto option at all.

    Oh, and congratulation on your fuel mileage by the way. That really is the top end of what can be expected from an early TJ. You must be a very smooth driver! ;)

    I'm seriously considering on of the new 2-door JKs, and trying to decide whether the Rubicon is worth $3k over the Sahara the way I would want them configured. The Jeep would be my daily driver, and my intent would be to use it off-road only on light trails in the Southwest mountains or desert, no heavy duty Rubicon-style boulder crawling or stump-jumping or mud slinging. If I go with the Sahara, the question is do I opt for the rear locker or would the limited slip differential suffice? Another question for the group--how does the LSD react on wet road conditions? Does it help at all on rain-slick roads or hurt? Any other effects on driving that the LSD would have?
  • erickplerickpl Posts: 2,735
    No experience with LSD (either type ;)) but the Rubi/Sahara choice is really up to you. Given how I drive my TJ, I'd opt for a Rubicon if buying one today. The lockers are nice if DO get stuck on those trails. Desert rain can make a trail into a river REAL quick, and having that capability is always nice. Plus, if you decide to sell it later, you have that much better resale.

    I never thought I'd wheel like I do now, so if you know you'll be doing trails and such in the future, it doesn't take much to go that next step and want to do something a little more challenging. :D

  • mac24mac24 Posts: 3,910
    The LSD is virtually invisible in day to day driving. The Rubicon/Sahara choice is more a queation of whether you want one as opposed to needing one, because for what you intend to do now, and a lot more than that, a non-Rubicon will be fine. Maybe a Sahara with a locker would be a good compromise.

    Hello everyone - I need some over the next few years my son will be out of his car seat soon and my wife is concerned about low back seat in case of a collision. I was wondering if anybody had found replacement back seats with headrest, putting front seat type seats in the back or something else.

    Thanks
  • I am considering purchasing a used Wrangler in the near future and I am having trouble choosing from the different models. I work at CARMAX so I will only be paying a little above wholesale. I'm 30 with no kids. This would be an everyday vehicle. Should I just get the most bang for my buck, i.e. Unlimited/Sahara/Rubicon? I don't really like the look of the Unlimited. What do I need to consider? Any help would be appreciated.
  • jplymanjplyman Posts: 90
    I drive an '06 Unlimited and am not wild about the extend back end look when the top is up - when its down - which is any time is not raining or freezing it looks great to me.

    The other nice thing about the Unlimited is that the is a lot smoother than the regular Jeep. Also, there is a good space between the back seat and the back end to through gear and stuff like that. Now that I have my Unlimited I would be hard pressed to give it up.

    I would say a big consideration is how much modifying do you want to do - The more you want to modify the more entry level model you may want to consider.

    Lastly which Jeep looks the best to you?

    Good Luck and enjoy!
  • The jeeps that look the best to me are the Sport & Sahara. Is there really that much difference between the two? Does one ride better than the other? By modifying, what exactly do you mean? Adding features that higher end models have?
    Thanks.
  • jplymanjplyman Posts: 90
    I would suggest you look at Cars Directs website b/c you can do side by side comparisons of the models to see which options they come with and are worth the money. I chose my unlimited with a package b/c I wanted the same color fenders instead of the black, and the auto-dimming mirror for example. These items that I wanted justified the extra cost - now I just have to sell my chrome grill... but for you maybe the extra won't justify the difference in cost.

    I would say that Jeep's are probably one of the easiest cars to modify and make your own. This can be a lift kit, new fog lights or more lights, new bumpers, side steps, different covers, wheels. Do a search for Jeep Parts and just watch the sites pop up.

    Thanks for the responses. But now I'm a bit confused as to the value of a LSD. If there is no advantage to a LSD on roads, whether slick or dry, what advantage would it provide off-road?
  • mac24mac24 Posts: 3,910
    You asked how the Wrangler's LSD reacts in wet conditions, and I said you'd find it virtually invisible. I didn't say it doesn't work!

    Off-road the difference in traction between wheels on the same axle is likely to be much greater than on-road, so the LSD will provide greater benefits. Again, the operation of the Wrangler's unit is pretty seamless.

    One of the reasons I said it would be invisible to you is that some LSDs can be quite 'clunky' as they do their job.

    I noticed that a lot of reviews on Yahoo talked about electrical problems; dashboard lghting up like a christmas tree, engine cutting out, etc. Anyone have any comments on he subject?
  • erickplerickpl Posts: 2,735
    The biggest electrical issue I'VE seen is in regards to the TJ's fuel gauge. There is an issue with the fuel indicator that causes it to drop to 0 on occasion. Something having to do with the unit in the tank itself. I know how far I go on a tank of gas, so I just use the Odometer most of the time. 90% of the time the gauge reads correctly.

    As for the whole dash lighting up, there is a connector between the body and the dash that that is EASILY cleanable and can be filled with dielectric grease to ensure good connections. Other than that, the only electrical issues are usually owner-created when adding stuff to their TJ's.

    Mac may have more, but that is all I've experienced.

    I looked at/sat in a 4-door Wrangler recently. One thing absolutely freaked me out. I am only 5'9", but it felt like the rollbar and speaker pod were aimed right at my forehead. Sure, you should be wearing your seatbelt, and yes, it is padded, but I could never be comfortable back there. My son is 6'1" and still growing, and he disliked it more than I did.

    Does anyone else hate that feeling? Granted, most owners aren't riding back there.....
  • erickplerickpl Posts: 2,735
    It is rather like that in my 97 Wrangler with the sound bar.

    I consider the back seats on a Wrangler (YJ, TJ, OR JK) to be token seats that are better served to hold groceries or car parts, or better yet, removed entirely. :D

    My rear seat is out most of the time. I only put it in if I HAVE to transport more than 2 additional people. I wouldn't want to have anybody back there when wheeling. Besides the bars, I'll be having fire extinguishers mounted on the cage, another potential hit location.

  • jimlw2jimlw2 Posts: 122
    I felt exactly as you did sitting in the rear of the new 4-door JK. I like the vehicle in general but that was on my short list of dislikes. I was rather surprised when I leaned forward and just barely cleared it while sitting still in the dealer lot. Can only imagine what bumping up and down might do to rear seat passengers' foreheads going down sand dunes...you'll need those extra storage pockets to hold bottles of aspirin for rear passengers :P
  • fenris99fenris99 Posts: 16
    What about pricing? I'm being quoted MSRP. :mad:
  • goducks1goducks1 Posts: 432
    I've heard they are in demand. You might have better luck at the end of the summer, when the 08s are coming in.

    Hey Newbie here, just bought a 2006 X with less then 1000 miles. When I am at a red light the Jeep is missing or misfiring. I have also noticed white smoke out of the tail pipe and a smut build up. Any ideas what could be the cause? :mad:
  • mac24mac24 Posts: 3,910
    White smoke is usually indicative of water in the exhaust, and when you combine that with a misfire it points to the possibility of a head gasket leak.

    The good news is that your warranty should take care of it.

  • wheelsdownwheelsdown Posts: 250
    Oh yeh, I remember you, I bet a few of us do. My TJ is a little over 7 years old now. Tom is still around but we have not heard from him in a while. Maybe this will flush him out.
