Jeep Wrangler Maintenance and Repair Questions (up to 1996)

    Sorry, but I can't agree with this at all. Unless a clutch has known weaknesses such as in a 6 speed Matrix (just as an example) it should easily last as long as most engines. (350k miles and up)

    While you make perfectly good points about correct operational practice, we will have disagree as to whether or not a clutch should be expected to last 350K miles.
    While theoretically possible (maybe if all journeys were long, started on the flat, and no stops and starts were made along the way), but it's as much an extreme as the clutch that gets burnt out in a day.

    To look at either extreme and say "that's how long a clutch should last" is unreasonable.
    A clutch is an item that wears, it's not like a wheel rim for instance that can only fail by losing it's integrity, and the rate of wear will depend on a combination of operator technique and transmission load.
    I think it's reasonable to say "the average life of a clutch is between 100K and 150k miles", but anything else would imply an unreasonable expectation to the owner.

    While clutches can and do suffer mechanical failure, failure to transmit drive because of a worn friction plate does not meet that definition.
    The clutch is just one of the items that can be expected to wear and need replacement during the life of the vehicle, and I believe that to expect otherwise would be optimistic in the extreme.

    I forgot to take into consideration geographical location. Hilly towns will can reduce that 350 to 200 or less.

    I have had the opportunity to view clutches after very high miles in cars and heavy trucks by drivers who knew how to treat a manual. I have seen clutches only half worn with 200k miles on cars, and of course 100's of thousands of miles on heavy trucks. Remember, many of these trucks endure stop and go rush hour traffic in any major centre they frequent. Car drivers could use the same techniques as truck drivers do to get more life from their clutches. Pacing and anticipating stops is the one of the most effective. I will allow that my 350k estimate might be a bit high with cars, as wear will accelerate as less friction material is left because it cannot dissipate heat as effectively and is certainly high in hilly terrain. Not unheard of though. Many people don't keep their cars that long, but for fun ask around to a few who have actually kept their car for 400 or 500k miles ( a VW TDI owner for example) and ask how many clutches they have done. You might be surprised to learn that many will have not had to do a clutch yet. Yes it is a wear item, but like I mentioned before, so is an engine a wear item and many clutches will last as long and even outlast the engine.

    Of course if maintenance items or neglect is practiced (like not fixing a leaking rear main seal) then all bets are off.

    YMMV (this acronym really applies here this time, doesn't it?) ;) :shades:

    No argument from me there. In regard to clutch life, 'YMMV' covers it perfectly! ;)

    I am trying to repair the horn on my 91Jeep Wrangler. I am missing several components to finish. Is there a exploded view diagram of the entire assembly with a parts list for the horn and steering column, from the steering wheel all the way into the firewall?
  • My 1993 jeep wrangler yj 4.0L has started losing power at highway speeds (60-75mph). It happens going up hill under a load, going down hill without a load and on level road without acceleration. I don't notice it at other speeds with in lower gears. It doesn't happen all the time. When the engine loses power the tach bounces and sometimes the engine knocks.
    So far I have used several different gas stations, added dry gas and fuel system cleaners. I've swapped the fuel filter. The spark plug wires are relatively new and not arching.
    Hopefully unrelated, the alternator failed and I had to replace it. I've run out of ideas and I'm looking for some ideas so I'm not arbitrarily swapping parts.
    Ay ideas?
  • i've beat the heck out of the rims that came with my '98 wrangler, i've a chance to get some nice looking alloy rims really cheap from a honda element part out deal... they've five lugs, but i can't tell for sure if they'd work or not. anyone know?

    I have a 1988 Jeep Wrangler. I live at 8000 feet, but bought the car at 5000 ft. It was running poorly when I got it home. I adjusted the carburetor, changed the oil, and adjusted the idle. Runs much better now, but still won't start fist thing in the morning. I have to add starter fluid every morning. Once the starter fluid is in it turns over easily and then will start, no problem, for the rest of the day. It seems as though fuel is not running through the line after sitting for several hours. What would cause this? I have heard rumors or a fuel injector on 88 Wranglers???
