    Spring with airbag - retention

    So, when performing a temporary fix for my tray mount, I noticed a rear spring sitting outside top retention guide(?) thingy. A quick lift with the forklift on hand allowed me to pop it back in. Yet to try inflating the bag - hope there's no damage

    So, two questions:
    1. Should the spring normally dislocate, in standard 130 configuration (eg with sway bar attached)?

    2. Given the bag being there I imagine dislocation cones aren't the answer, what is?

    Not sure if this trip is bringing me closer to my kids or my Defender! Either way, great experience being acquired!

    Hi Ranga my set up is close to yours but a 110, no sway bars though and air bags. When they lifted it on a chissis hoist to fit new tyres a couple of months ago I checked and the springs did not dislocate. Are your shocks standard travel?

    I've had the top of the rear spring dislocate and rub against the inner sidewall of the tyre causing the tyre to burst.

    For the last 10 years, I've used two hose clamps to retain the top of the rear spring on the rear of my 110 with poly-airs. Occasionally one clamp will snap in heavy articulation.

    are you running at least 5psi in your airbags all the time, if so i would have thought that wouldhave held your spring in place

    the new shocks i have installed on my defender must be slightly longer as i had a spring dislocate, i don't have airbags at the moment so i might do the military 110 mod

    Seeing it is a 94 from your signature, my guess is that the shocks have been changed a few times.

    IMHO , the only thing that really causes spring dislocation is when the shock and spring are not matched, IE the shock extended length is more than the free length of the spring. It may be that even when the shock length is only a little shorter than the spring free length that this can also happen after a big jolt.
    If you want a cheap fix, just add a retention strap to the axle where you are confident that the spring will not dislocate.
