    Hey Guys.

    im new to jeep!

    just got my CJ5 home today.

    1.
    Should i use unleaded octane 95 fuel and then add lead every time i fill fuel on the car? Its a straight 6 cylinder amc258 engine.

    2. How do i put the jeep into 4WD ? on the front wheels there is a "switch" for position 1 or 2. its a 3 speed manual. The ekstra gearshaft have the following: 4H 2H 4L and N, but when i move it forward and backwards i can move it a long way (i have done nothing to the switches at the wheels, where should they be? ) But i can not move the gearshaft from side to side..

    Also it seems to drop just a little oil from the gearbox from under the car.. i assume it is the gearbox.. it is someting that sticks down from under the car with a shield on it for protection..




    Please help :)

    Best regards mikkel from denmark.

    Unleaded fuel should be fine without additives...although 95 octane seems high. Here in the U.S., 87 octane is the normal fuel.

    The "switch" is called a hub...likely a Warn hub (the name brand). In order to lock in the front wheels for four wheel drive you must turn the hubs to the 4x4 position (not exactly sure how yours are labeled), and then change your gear shifter into either 4H or 4L (high or low). You need to be at a stop...or extremely slow crawl when shift into 4 wheel drive.

    Okay - here in Denmark the lowest is unleaded 92! So i will use that without additives!

    Okay the hubs have a label "1" and "2", and maybe one thing more, buit sure because they are scratched a lot! (made of plastic it seems). So should the main gearshaft be in no gear?, and should i press down the clutch when going into 4WD on second gearshaft??

    Thanks

    If you can, put both hubs to "1", put the front wheels up off the ground and turn one wheel. If the hubs are locked, the other wheel or the driveshaft or both must turn. If nothing turns, set both dials to "2" and repeat.

    In gear or out, doesn't matter. The hubs lock or free the wheels from the axle, regardless of the shifter position.

    For 4WD, put the hubs to locked, and shift into 4H (4WD high range) or 4L (4 wheel drive, low range). The shifter will be almost touching the toolbox when in 4L.

    You can shift from 2H (2WD high range, used for driving on highways) to 4H at any speed, as long as the hubs are locked. If you try to shift into 4H while moving and the hubs are free, you will hear terrible grinding noises... avoid!

    To shift into 4L, you can be rolling very slowly (baby crawl speed), with the clutch in (pedal down) or the transmission in neutral. Shift into 4L with a clunk - that's ok.

    What is the shift pattern on the D20 transfer case? Is 4H all the way forward like mikkel's said is on his knob?

    M1KKEL,
    On my 75 CJ Cutlass Hubs, there is a 2 and 4 on it, Mabey if yours are soooo scratched, the 4 might look like a 1,,, In the 2 position the front diff is unlocked for 2 wheel drive and when it is in the 4 position, the front diff is locked for 4 wheel drive
    Hope this helps

    Hey. Im sorry i wronte something wrong, i have to numbers on each hub, "2" and "4". I tried today driving in "4", and the gear have always been in 4H, and then i pressed it down in 2H when the car was rolling, and the then there was no traction. So i will try to put them into "2" and then press it down in 2H - but when i put them in "2", is seems as the wheels on the right side of the car is braking a little bit.. should i move the steering wheel to get it into the right place, or roll a little forward and backwards before the axles shift in?


    Lol being said that the gear is in 4H i have just driven 250 kilometers with 4 wheel drive.. no wonder the car was loud as hell! but i didnt know better!

    If the hubs were locked into 4, and you were in 4H, then you were in 4WD...but when you shifted to 2H, you should have still been able to move forward from the rear end. Your post makes it sound as though you lost ALL traction...does that mean forward power...even from the rear axle?

    Well the car definately made a different sound, so i shifted back to 4H right away, and the car was in movement when i did it - so actually, im not sure if a lost ALL forward power. Tomorrow i will check with 2H and hubs in "2".

    But, I were in "4" and shifted into 2H, how can i still have forward power then, i thought that to be able to change from 4WD to 2WD i had to change hub position - what happends if i keep driving in 2H and hubs are in "4" ??

    When you're in 2H and hubs are in 4, the only thing that happens is that the front axle is turning along with the wheels, because they are now "locked" to the hubs, but your transfer case is not "locked" to the front so there is no power driving the front.

    The rear should always work in 2H regardless of the position of the hubs on the front axle.

    When you wrote >no wonder the car was loud as hell!< Are you referring to loud engine noise? Loud transmission noise? Or loud exhaust noise? Where was the noise coming from ???

    well i have never driven a jeep before, so ofcourse i have nothing to compare it to. But it sounded like loud transmission noise, in combination with loud wind noise from the softtop, and this was at 80 km/h. But i have nothing to compare it to :( Later today i will try to see if i can get the jeep in 2WD!

    Hey guys.

    Today i put the hubs in position "2", put the gear in 2H (wass hard to find) and that worked like a charm. nothing was blocked, the was waas much less loud when driving 80 km/h, and seemed faster aswell. Thanks for your help - this is a great forum.

    Maybe i can ask another question, when engine is in idle, it coughs a little so its not 100% smooth (hard to explain, i can make a sound recording) how can i fix that, or maybe its normal for this type of engine / car. Or is it the camve timing or something similair ?
    - and if so, can i do it myself - is there a guide on the web for this ?
    Regards Mikkel

    Good to hear that 2 wheel drive works well. I'll offer up the link to a '74 model year Factory Service Manual that you may want to download. It will have lots of good information, including troubleshooting tips.

    http://oljeep.com/edge_74_tsm.html

    I think that you'll find owning a Jeep a very educational experience.

    Thanks man, those links are awsome. Really good, then i might not need haynes manual. Actually it is a '75, i miswritten (i may have been tires from the long ride home in 4WD :) )

    I think you are right, i just hope i can figure out how to fix things - im not a idiot with my hands, but im not a educated mechanic. But i can learn whatever i want!

    Thanks for good help and support.

    the main difference between 74 and 75 is wiring i believe a 75 has a "real" fuse block where the 74 has inline fuses
