    98 eldo suspension issues

    So a while back I posted about the lean codes I had. I put a new o2 sensor. And new gaskets for the TB. Everything looks good now. But before a trip to get the car smogged we inspected it on a lift. We saw the cv axle boot was ripped ( will change soon) but we also checked out the rear suspension. The rear of the car has been sitting WAY too low.

    We know the compressor works cause we hear it everytime we turn it on. But it doesn't raise for anything. Last time we had about 4 people in the car , full tank, and some supplies in the back and it would never raise. So there was this plug thingy that was supposed to be hooked up to the rear shocks but it was just dangling there and it was broken.

    So we decided to get 4 new struts. 40046 monroes and 90011. Do these have any issues with the car when installed. And are they compatible with the elc? I don't want to lose the Cadillac smoothness but also not to break the bank. So any advice would help.

    And for anyone who read my last thread on lean bank 1 it was a faulty o2 sensor and a torn gasket in the tb ( not plenum) w/ a loose bolt holding it " together"

    40046 monroes and 90011.
    Do these have any issues with the car when installed.
    And are they compatible with the elc?

    ------------
    those are the correct parts for your car -

    the rear shocks are a direct replacement -
    and will make your Eldo ride just like new -
    -----------------------------

    one member recently had an issue with using the 90011 front strut kit -

    he had someone else do the labor - so we don't know what they did -

    he said the struts were correct - but the strut mounts were not correct -
    and caused the car to sit too high -
    they installed the original equipment strut mounts -
    and everything was fine -

    this is the first time I have heard of any problem with the 90011 kit -
    and I have been recommending it for years -

    are you doing the work yourself - or having it done?

    have you already purchased the parts -

    if not - here are the best deals -

    90011 - $166.21 - with free shipping -
    http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

    40046 - $108.07 - each - with free shipping -

    Are there any cheaper alternatives? Which give the most dampening, front or back?
    I want the most bang for my buck. So would you recommend putting a pair of normal shocks in front and Monroe 40046 in back? Or vice versa. As I said I want to keep the cadillac ride but not breaking the bank.

    --------------------------------

    maybe a used worn out set from the junkyard -

    Which give the most dampening, front or back?
    that's like asking which shoe gets the most wear - left or right -

    the answer is they both do -

    if the front struts are worn out -
    the front will bounce more than the rear -
    so they should be replaced first -

    if the rear shocks are worn out -
    the rear will bounce more than the front -
    so they should be replaced first -

    one exception would be if the bladders in the rear shocks are blown - or leaking -
    so the rear of the car is too low with stuff in the back seat or trunk -

    if that is the case -
    it would be more important to replace the rear shocks first -

    So would you recommend putting a pair of normal shocks in front
    and Monroe 40046 in back?

    you can't put "normal shocks" - whatever that means - in the front -

    your car has struts in the front -
    the Monroe 90011 kit IS the best value for front struts -

    and the Monroe 40046 IS the best value for the rear -

    On the monroe website it has 2 90011 part numbers.
    One has electronic suspension and the other does not have electronic suspension. So what do I call for? I'm extremely confused.

    -------------------------------
    not just confused -
    but EXTREMELY CONFUSED -
    OH MY -

    read the application - and description -

    90011 KIT is front struts for BOTH sides -
    it CAN be used to convert electronic suspension
    to passive - non-electronic - suspension -

    the same 90011 kit CAN be used in non-electronic suspension systems -
    -------------

    Monroe is in the process of re-packaging this kit -
    they are no longer putting everything for both sides in one box -

    they are splitting the kit up into two boxes -
    one box has everything for the RIGHT side - 90011-1 -
    and one box has everything for the LEFT side - 90011-2 -

    when there are no more 90011 kits available -
    you would order 1) 90011-1 and 1) 90011-2 -
    ---------------------

    if you did have electronic - active - suspension -
    and wanted to retain active suspension -
    you would need to order the much more expensive
    40016 and 40017 struts -
    -------------------

    for the rear shocks - you actually have 3 choices -

    one we can eliminate immediately -
    the 30141 - which is one single shock of the 90009 kit -

    the 90009 kit - or 2) 30141 shocks - are a coil-over design -
    rather than using the air bladders the others use -

    it is a HORRIBLE CHOICE and makes the car ride like a truck -
    so - lets just forget about them -

    the 40046 is the correct shock for those cars without electronic suspension -
    or those cars with electronic suspension
    that you want to convert to non-electronic suspension -

    lastly - the 40018 is the correct shock for those cars with electronic suspension -
    that you want to retain electronic suspension -

    Weren't there a few members who said the monroe quick struts on the 00_05 had an extra coil on the springs included so it sat higher like the 06+ DTS do. Could the spring be part of the problem here as well?

    --------------------
    quick struts are not available for the OP's car -

    if you are referring to Devilles -
    I have NOT heard of any fitment problems -

    the 90011 kit is labeled "use to depletion" then order 90011-1 and 90011-2 -

    the 90011 kit is $166.25 - with free shipping
    on amazon.com -

    I haven't seen any prices for the new 90011-1 or 90011-2 units anywhere -

    but I doubt you can beat the amazon price -
