Advice please on self levelling shock absorber.

  1. I had an MOT fail on the Scorpio for oil on one shock. (I have a faint suspicion suddenly appeared during the MOT, but I digress). A secondhand one has been aquired which looks dry although the boot is rotten, but I am surprised that with my weight on it, it will not compress. Is this normal for a self leveller, or is it seized please?

    all you can do is fit it and see Scorpio is not a lightweight barge at best

    springs for non leveling are also different to leveling ones

    They are gas filled and I doubt you will get them to move !!
     
  6. Norm, that is very interesting. Before my MOT, I had done a lot of work on the bottom of the car and saw nothing in the way of leaky shockers. When it went into MOT, it failed on oil dripping off the bottom and on the lower part of the piston rod, apparently from the shock absorber. Now if it is gas filled, where did that oil come from? It did have the characteristic smell of EP80/90 too.

    Shocker oil hardly smells IMO ep 90 cat urine as you know
    Well... if the shocker is dry it cant fail :whistle: best day is a rainy one :whistle: We dont/ cannot do a bounce check now.;)
    Gas filled still leak but i think you would see the obvious loll of the car because its the gas that holds it up (that is not lol btw :waving:) and the gas would be GONE
    LOL:thumbup:
    got to go MOT to do at 13.00
     
  8. I have to withdraw my casting of "perspirations". Just looked at the shocker and it is again wet with oil, clearly failed between my last inspection and the MOT. Tester was very good actually, finding a drop link that has excess play which I had missed as well as the airbag light that had behaved for a fortnight, but came on during the test. So the shocker needs replacing, a job that I am not looking forward to as it seems to require much rear end disassemby. Oh well it will just have to wait until I have the time and interest.

    Rear of car on stands car on stands wheel off jack up suspension arm remove top bolt there used to be a blanking plate over shocker if not remove trim panel
    undo two bolts holding bottom shocker mount slides out no need to touch the spring etc
     
  11. Nope! Self levelling are thicker and will not drop through the hole in the wishbone.
     
  12. Ford instructions
    http://www.fordscorpio.co.uk/manual/suspension/RAxleShockAbs.pdf

    for the estate with self levelling are to start by removing the spring with this procedure...
    http://www.fordscorpio.co.uk/manual/suspension/RearRSpring.pdf

    Then swap the shocker before putting it all back again. Looks like a few hours work to me.

    I have pondered on dropping the shocker, then using spring compressors to remove the spring. I assume that Ford didn't want their bunnies using such lethal tools which is why the disassembly? Or am I in cuckoo land again as usual?

    are you sure it won't drop out the bottom long time since i did one but certainly didn't remove half the stuff the ford manual says
     
  14. I think the key is that it is an estate. The saloon is simple in comparison.

    The Gas doesnt just have one function on self levelers it doesnt just keep pressure on the oil, to maintain damping.
    It actively levels and lifts the car, taking the weight of some of the load. The gas is in an accumulator.
