    Default 505 rear coil springs removal

    hello
    i'm going to replace the rear springs.
    haynes says drop the final drive onto the cross-member. how is it possible if the torque tube is attached to the gearbox?
    and what bolts (ie size and pitch) should i get to screw through the plug under the rear seat instead of the tommy bars?
    thx

    Why are you replacing them, 2pac ? I've never known 505 rear springs to sag, though 504s were notorious for it.
    And when I replaced my 504 ones, I regretted it....the rear was much harder. I should have used secondhand 505 ones.

    My 84 car has a very high rear end and the body is inclined, which doesn't look too good. I got me a pair of springs from a 88 whose rear end was much lower than mine, and the body was horizontal. they are marked in different colors ( blue instead of red or yellow).

    To remove the rear springs you must swing the trailing arms down a long way .
    To do so , remove drive shaft , disconnect sway bar from trailing arm , remove rear shock .
    Then loosen the bolts on the front of the arms , swing arms down and remove spring.

    That's one option. I did it this way in a car I was breaking and i needn't loosen the pivot bolts of the arms, I just don't want to mess with the drums.

    If you dont want to mess with the drums , remove the exhaust , unbolt and remove the diff from back of torque tube and lower the arms together, this will allow you to get the springs out

    The diff oil should lubricate them.

    Peugeot 93' 205 Gti 16v
    Peugeot 73' 504 Ti from new
    Peugeot 08' 407 Hdi Coupe from new

    The rear of my 505 GTi sags as well. The ride is harsh and I suspect the springs and shock absorbers are aftermarket replacements. Thanks to all for the suggested replacement methods.
    I will look for original Peugeot springs and, perhaps, modern gas assisted shockers.
    One trusted mechanic suggested fitting springs from the diesel models to my petrol version.
    Worth looking into.

    As BigRR says : the diff oil.

    And just in case you are unaware, the drive shaft outer splines and both prop shaft splines are best lubed with Molydenum grease.

    Could be interested if the springs suit my 1985 series II GTi. Please sent details; cost, shipping etc.
    I am gradually improving this car, but prefer original parts if possible. Thanks for your interest.

    the manuals say use molykote 321 dry film for the outer splines. when the garage replaced my driveshafts gaiters they didn't lube them with nothing.

    for the propeller shaft splines, haynes says "grease", and an online 504 guide says "multi purpose grease H", which is just a general grease.

    anyway, i'm going to do that this morning in the method of disconnecting the diff from the propeller tube, and i bought this grease for the propeller rear end splines.

    The rears are the same for the diesel models. The fronts are different because of the heavier Indenor engine. There are plenty of up-rated rear springs available in OZ for the 505.
