    So when I'm driving the jeep , 66 cj5a, around its got almost dangerously rough suspension. For instance I was driving on a back road to a buddy's house. The road was moderately bumpy for a normal car but for the jeep it was bouncing me everywhere to the point I could hardly control my steering. I was thing about making a coil spring conversion into it but I just thought there may be a better way to go about it. Any thoughts or suggestions? Thanks guys!

    And, how fast were you going? How much air pressure in the tires?

    Yeah, slow down a little!

    Count your leaf springs - if it's more than 9 or 10 in a pack you may have a heavy duty suspension, and could remove one or two. But if your objective is a soft ride, you need an Oldsmobile, not a jeep.

    In my opinion, you need softer springs.
    I'd like to know what springs you have. You say you have a 5A (Tuxedo Park)? From the factory, those had two-stage springs. Should be 6 leaf front and 5 leaf rear. The two shortest (bottom leafs) should be flat, and the longer ones arched.
    The vehicle normally rides on the longer leafs which are quite soft, and only hit the flat leafs at the end of travel. The 5A suspension was actually quite sophisticated for its time, especially for a Jeep.
    From your description, I suspect your springs have been changed. Heavy duty springs could be ordered on 5As, but most came with the two-stage springs.
    Actually, the two-stage springs are better on the trail too because they allow better articulation. It took me years to discover why, as my Jeep consistently kept more tires on the ground where my friends always lifted a tire.

    short wheel base jeep . will be choppy on any road not flat . just nature of beast . new springs help some . tire pressure . slow down . now if you want coil springs just buy a wangler . not worth the trouble . with 81" WB

    The same for me, but I have a lot of springs, 11 at the rear, it was a heavy duty Jeep for snow work.

    But the subject is tires : they are old and hard like steel. I can deflate them but not too much.

    When deflated at 1.6 bars, it is better.

    I should buy tires for cars, not for heavy duty like agriculture with plys. You should change your tires.

    I changed my shock absorbers and I saw a difference.

    I bought standard ones, I suggest you to buy a top quality, more expensive + good road tires and it will be OK.

    Afterwards, you can change leaves but I don't think it is useful. It is a Jeep.

    Or you replace them by circular springs but it is not a Jeep.

    I was only going 30. I think the yj conversion with some new shocks would probably do the job! Thanks guys

    I have a 1965 CJ-5 F134. 7 leaves in the front, 9 in the rear. Is this heavy?

    My '71 with V6 has the following:
    5 Front
    5 Rear

    According to the FSM...I'm short one leaf in the front. Of course we all know most Jeeps have been or are donors of other Jeeps.

    Airing the tires down to 15-20 psi helped out alot on mine.
    Should try my jeep;) dana 70 dually and umpteen springs front and back. Think it might as well have the axle welded to the frame:D

    Question.

    I can bounce on the front bumper of my CJ and it's rock solid stiff. Shouldn't there be a little give?

    Edit - I just removed the front shocks and did a road test...Dreamy. Maybe my shocks are crap?

    They're definitely garbage. I can compress them by hand and they stay compressed...They don't even try to expand.

    Not all shocks will expand with no load. Only gas shocks (nitrogen, etc) will extend themselves. The old-school shocks the Jeep came with were only dampers.
