    I decided to get some donor wishbones and rebush them so i didnt have to waste time trying to do this with the car jacked up and waiting

    These were actually off an S3 but same front subframe setup

    I then gave them a good wire brushing down to remove all the crap and rust, etc. from them
    I opted to rebush my set with powerflex bushes (took a while to get after the fire though)
    Here are the pics of the new ones to replace the old

    This rear bush actually split down the middle so quite easy to refit once removed

    The most difficult part of the rebushing is the removal, the rears especially so here is how i removed them
    This was my setup in work vice, piece of solid bar, a 2" pipe connector and brute force
    [​IMG]
    Here is the size of the fitting for anyone needing rough dimensions
    [​IMG]
    Keep tighten the vice more then backing off to break the rubber, be careful it is straight or it might ping out and a pretty hefty vice is a must.
    After a while this should happen
    [​IMG]
    You can then easily pull it out
    Then get a hacksaw and remove the blade and feed it through the new hole in bush to allow cutting of the casing

    Afetr cutting through the casing get a suitable screwdriver preferably pound through and punch the casing out on the split
    [​IMG]
    [​IMG]
    Try not to cut into the actual wishbone though, you shoulf feel the difference as the wishbone is steel and the casing aluminium
    A quick clean of the inner bore to remove rust and debris with some scotch bright
    [​IMG]
    The new bush can then be lubed up with supplied sachet and pushed in by hand from either side then clamped in vice to send it fully home.
    These are the most difficult to remove
    The front bushes can be removed the same way but if using poly for the front a hydraulic press is needed really hence no photos as they really take some pusshing in, i did mine at work
    A garage/ engineering company can push these in very easily as access is plentiful on this end.
    When finished should look something like this

    All now ready to go on the car

    I didn't use a vice to replace mine, although the metal tubing was used in a similar way. I actually used a threaded rod through the middle, several washers and bits of metal with two nuts either end, then a nice big wrench to wind it in until it popped like you show in one of the middle pictures.

    As for the larger ones, I just pounded away at the metal casing until it deformed and fell out, no bother there. I also didn't need a hydraulic press to fit the new bushes, although they are squirmy barstewards! Again, a bit of threaded rod, with some large plates of metal and two more nuts, and the whole thing just needed a couple of spanners and a LOT of patience! It took at least a dozen attempts before they stayed square and got pushed in sufficiently for the lip to 'pop' on the far side.

    The poly bushes were fitted at the same time as the coilovers so difficult to know exactly how much difference they made but having rebushed a set with OE the poly much firmer.
    To push new OE bushes ina hydraulic press is not really required but the poly ones are very stiff and i think you will really struggle as they are so tight. It wasnt that easy even with the press

    Tightens up front end nicely, also stops tyres wearing unevenly on inside edge once tracking set correctly, i didnt notice much more vibration with bushes when i fitted mine after the coilovers.

    So how are the tyres after this is done, are the old bushes the cause of inner tyre wear due to all the adjustment being taken up?

    First set of ps2 tyres wore on inside edge, but still had plenty tread on rest of tyre, second set of ps2, which im just about to change now have done 5000 miles more than 1st set with bushes fitted.
    It might be the coilovers & bushes together that are the cause of even tyre wear, but i think the bushes are the most contributing factor by keeping the wishbone soild and and in line.

    It was poly bushes that I fitted (Powerflex) and I totally agree they were a struggle! :) I did find it funny the instructions actually said they can be fitted by hand, like bo**cks can they!! The two part ones yes, but not the larger ones!

    Forgot to add that after fitting a 4 wheel alignment should be done and the camber can be adjusted on the slots for the balljoints
    I am currently running 1 degree of negative camber per side(OE is is roughly 0.3 to 0.5 or something), this will make the tyres wear on the inside a little faster but should aid turn in and handling

    I believe the method of installation is the same, but the bushes themselves are a different size. You can see the different part numbers if you go to the powerflex website and look at their fitting guide. I believe the large bush is a different size.

    LCR, TT, S3 all have cast wishbones requiring the larger front bush
    LC has smaller pressed wishbones with a smaller front bush
