Hey all

I'm hoping to get back into the s3 in the next few weeks.
It's been a while but last time I worked on it I was starting to remove the chassis (suspension) bushes.
Just wondering if anyone has rigged up a horizontal press with a bottle jack to remove and install? Or should I just do it the struggle way? Melt, cut, chisel, clean, freeze and press?
Any ideas to make it easier would be great!
Cheers

My father-in-law made an extractor for me. Not a fan of burning the old bush out.

Cut through the bush inner, & outer with a hacksaw. Switch to a coarse blade when going through the rubber.

Drift out the old bush.

Pull the new bush in with high tensile allthread & nuts and washers turned up to make sure you don't damage the bush

Bushes from a Series I, originally two small bushes used. replaced with a single long bush.

ColinHey Colin

I figured this was the path I had to take, same way I done my radius arms on the D1.
Is that a really long socket you have on the left? I done mine with a bunch of washers last time a bit painful.
Also did you freeze the bushing overnight before hand?
If I was going to take the motor out I would have just flipped the chassis and built a press around it with a bottle jack haha.

On the left is a large diameter bar that's been bored out to accept the bush being pressed out. With spring bushes the new one pushes the old one out.
There is also a spacer that transfers the load to the outer casing of the bush rather than pushing on the inner at the same time. Plus there is also a tapered washer that centralises the allthread when you draw a bush into the chassis.
I haven't frozen the bushes I normally use Copaslip on the chassis bushes but install dry in the springs otherwise the bushes can move and it makes one hell of a bang as the leaf moves on cornering.

I just burn the rubber until i can push it out of the outer bush.
A recipro saw blade will then fit and you can easily cut the outer bush. If you cut it in two or more places it is easier to remove with a cold chisel and hammer.
Then its lots of work belting the old bush out.
I only put urethane bushes black in and these if greased can be pushed in with your fingers.
Urethanes are available in black if you are fussy.

Personally not a fan of the poly bushes, several discussions on the forum with two distinct camps.

I've had the anti-crush tube on poly bushes seize onto bolts so they have to be cut through and also also the original type seize onto the bolts.
I've fitted poly bushes on other vehicles and you do have to take them apart to re-grease when they start to creak.

Never had any real issues fitting the original type bushes which are fit & forget. Just a few basic rules like grease the bolts so they don't seize and don't tighten the bolts until there is a load on the springs.
