    Default DS Invagination

    Greetings all

    well!! today was supposed to be all about me! Baking a birthday cake with Mum.. however the DecidedlySpecial had other ideas. I had drained the Hydraurincage from the can and filled up with new LHM.. took the car outside for a bath and on inspection discovered the rear right suspension boot torn! ugggghhhhh!!

    With a quick call to Mr Kennedy I was able to verify the correct replacement procedure and indeed what would be required for the manoeuvre that is "invagination".

    Removing the cylinder wasn't too difficult. There's a small 8mm nut/bracket that holds it all in place?!?.. undid that, removed sphere, undid pressure feed and cut off drain hose. the boot part I mean.. removed ball and cup retaining pin and withdrew the cylinder towards the front of the car.

    You can see previous repair had used a screw clamp.. but the linen cloth for the ligarex on the other end was intact. As advised by Richo I simply replaced everything in reverse to ensure I had the boot on properly... pushed it onto the rod inside out.. refit cloth tape and new ligarex and then turned right side out and woo hooo!! invagination a go go!!

    All cleaned, replaced with new (original) boot and ligarex straps, new pressure line seal.

    Wisdom tells me I should do the other one as well.. but alas no time today.. back to the grind tomorrow unfortunately. Still once you've done it, the second time around is easier.

    Richo, many thanks once again my friend.. it's always good to have someone you can rely on for advice, especially at short notice.

    Bravo on tackling another job. With the right approach its an easy task. With the wrong approach all sorts of things can be damaged.

    Wisdom would also say how good is the "on high" bump stop? It stops the piston from forcing out on the boot.

    Nicely done Matthew.
    A pleasure to be of remote assistance.

    You're the one who is able to understand and follow instructions, to the letter. Matthew, that's a rare, enviable quality.

    Thanks for sharing the images.

    I should take a shot of my boots, they are waiting for invagination tout sweet!
    So much to do so much time...
    Looks exactly like what has to be achieved thanks, did you have to file anything back or grease the cups?

    Hello

    I had replaced the balls and cups last year so they are good to go. They did need replacing though at the time.. the cups were badly scored.. giving that "click click" when the car rose after start up.

    You can follow that on another thread.. "DS rear cups".
