    Front Suspension STD

    Main components and their names
    The mk1 golf platform (and mk2, mk3 etc etc) uses a MacPherson strut front suspension setup. This system is used in all sorts of cars by all kinds of manufacturers. The basic components don't change, those are:

    Wishbone / Control arm
    Wheel bearing housing assembly
    Strut /shock absorber assembly
    Track rod /steering arm


    The Wheel bearing housing assembly is the bit not labeled in blue that the wheel bolts on to.

    Bolt sizes / tools required listed by component

    Chassis Mods

    For when your truck is just sooooooo low you need to take bits away or move things to get that extra clearance!

    Notching the chassis legs

    What is notching and why would I want to do it?

    I want to notch my chassis legs - how do I do it?


    Raising the turrets

    What is a raised turret and why would I want it done?
    Answer by Mugglesquop
    Raised turrets allow more suspension travel, so allow you to go lower if you have run out of adjustment on your coil overs. You are raising the mounting point for the top mount, so the suspension is mounted higher than normal thus bringing the wheel up closer to the arch.

    The raised topmount allows the suspension more room to move vertically and work more naturally. It will change the angle of your wishbones and driveshafts. So can put extra strain on the other suspension components, not a mod to be done in isolation!

    some pics...

    ooh! something to do today

    Some ideas

    Shock comparison & part nos
    Bolt sizes for stub axle & u-bolt
    Which way round a spring goes
    Why does my axle flip loose my wheel position – did I make a diagram of that?

    The red circle is as standard, and when you flip the axle it moves to the blue circle and scrubs at teh top front. Centralising it put is back to the green position in the centre of the arch.

    How to centralise my axle
    “Bodges”/how not to do it

    Some Dodgy mods/fixes to watch out for:
    Incorrect Axle flips - Saddles welded on wrong, locating pin/bolt missing, u-bolts replaced with threaded rod
    [IMG]Attachment 11253[/IMG] [IMG]Attachment 11254[/IMG] (thanks to thiggs)

    Dodgy camber mods – mis-matching washers stuffed between axle and stub axle to give “stance”
    [IMG]Attachment 11255[/IMG] (thanks to motobruce)

    well you can see the style of what i'm trying to write. Short, direct questions with succinct answers to avoid people getting bored and not bothering to read it!

    Any questions I haven't covered above and any answers you can write would be awesome - with supporting pics if possible!
