front air spring strip down/removal

Post by benp » Sun Dec 09, 2012 9:51 pm

as ever just a guide and if you break yours we was only trying to help ;)
tools
Jack
stands & chocks etc
24mm deep socket/spanner
22mm socket/spanner
10 mm spanner
12mm spanner
15mm RATCHET spanner (you will cry if you try with an ordinary spanner or a crow foot imho)
Torque wrench
flat blade screw driver
posi driver
long nose/snipe nose pliers
bull nose pliers
soft face hammer and a soft drift
Air compressor if you are replacing the seals not required for replacing the spring complete
oh daylight would be handy too :lol:

Jack and support the D3 removing the wheel

Image

deplete the air if you have an IID or similar .... I didn't really have to worry about this :roll: and if you dont have a tool I would suggest when time comes just steadily slack the voss connector

remove the grill and the head light to give access to the wheel trim screw

Image

Image

you then work round all the plastic expansion rivets I found the best way was to start them with a flat blade and then pull them out with a pair of long nose pliers

Image

take out the inner wing cover to aid access there are loads of screws and rivets now I knew mine wasn't going strait back together so I put the screws back where they came from

then I cracked the shock absorber bolt so it was loose but still in place 24mm and 22mm

Image

then remove the bolt from the heat shield 10 mm

Image

then work round the retaining nuts for the spring with the 15 mm spanner

Image

now with some inevitability the back nut was a complete bu66er to get off you can only get an 1/8 th of a turn on it and if I hadn't had a 15 mm ratchet spanner I suspect the will to live would have been lost ;)
I got all the nuts free then put the one that doesn't clamp the bracket round the voss connector back to hold the spring on.

Image

then undo the Voss connector 12mm spanner be aware of stored air pressure

remove the air line
Image

I would recommend covering the air line to prevent ingress of dirt ... I used summat rubbery



Image

a glove you dirty minded lot :roll:

remove the shocker bolt and undo the last spring bolt and remove the spring. If you are replacing the spring and shocker complete do it now ;)

pull out the plastic stop rivet
Image

I measured the top nut before I undid it and noted it down .
Image

hold the spindle and undo the nut
Image

you are then faced with this
Image

I found they came out when tipped the spring upside down and gave it a knock with a hammer
Image
Image

separate the spring with a good tap with the soft face hammer

Image

separate the seal


Image
and you can pull apart the spring




Image

remove the bump stop to change the large O rings clean every thing and re assemble I used a bit of thin oil on the O rings to help with the re assembly, get the seal started as best as you can replace the top seals and nut then pump it up with an air line

Image

then listen to the air leak out or not as the case may be ;)

replace or refit the spring as required to the disco

So was definately the bag at fault then? Where did you get the replacement?

Tlo in a rush no one else could get one for ages :cry: ho hum tis only money .... well overdraft ;)



Cliff the spring is a piece of pi$$ to change tbh ... if any of you get an ail leak spray some soapy water round the spring if it bubbles near the ally sheath the air bag is f :censored: d dont mess about with seals ;)

The koni instructions are great, I've used it before. I have a pair of rear springs ready to put new shocks into here, then will swap them over when I get a roundtoit. I think you can get them at b&q although I do need quite a few of them.....
