Hi, this time I'll show you how to replace the rubber mountings of the rear axis at a Golf Mk1
The replacements for the rubber bushs are made of polyurethane
For this repair I have to jack the whole rear axis, thus I secure the car at the front wheels
Before jacking the car, I loosen the wheel bolts
I remove the bolt caps. They are still original, what a quality
Jack the car at the rear axis support
and support it at this holders
One side is up and on the jack stand
Now I am going to check the other side in the same way
I will lower the whole axis carrier now
The brake hoses here are to short, thus I have to disconnect them from the brake lines
The axis carrier is mounted on 4 bolts
Now we have the choice, either I open the bolts here or the nut on top of the shock absorber
Apply some rust remover to the bolts
Because I jacked the car not very high, I have to remove the wheels to lower the axle carrier
For opening the brake hoses use in any case a flare nut wrench
The screw caps I made myself
This connection was fastened very hard
The other method to close the lines
I open the nut of the struts
They are under these covers
For opening the nut you'll need such an long open socket or a box-end wrench
The fitting selfmade tool for these would look like this one, which fits for an Audi
Only loosen the nut, don't remove it
Same procedure for the other side
Now, I am going to open the nuts on the axle carrier
Let's hope that I don't kill a stud
Let's start! Ah it was easier than I expected
Also no problem on the other side
Now the axle carrier will come down, thus I support it with a jack
That's a jack. It is from a 1951 Volkswagen
On the rear side are also nuts
Lower the axle slowly
Take care on the parking brake cables
I'll open the nut on the long bolt thru the axle mount
Keep the positon of the mount in mind
Open the nut
The plane washer is on the inner side
The round washer is on the outer side
The round side of the block is on the outside
Some cracks outside but for 30 years, a very good quality
A VW-garage would have replaced the whole mount, but the spare part isn't avaiable anymore
Thus we have to replace the rubber bush in the mount with a polyurethane bush
Apply some glycerine to rubber bush
and press it out
Pressing the polyurethane bush in the mount will be a hard job
We tried to press it straight in, but it was hopeless
Either it went to the side or it became very thick
We'll press the bush now from the side and then we will turn it in the mount
Apply the special grease, it looks like vaseline
And now the metal bush
The concave washer to the concave outside of the mount
The flat washer at the inner side
Insert it in the hole of the axle carrier
the small washer
and of course we use a new lock nut
By the way, the thread is 12 x 1.5 mm
The nut on long bolt gets 70 Nm
Using the jack I lift the carrier in position
and the nuts for the other side
Fasten the nuts of the carrier with 45 Nm
The axle carrier is now fixed at the front
Thus I fasten the nuts on the stud bolts
and finally I fasten the nuts with 35 Nm
Install the nice caps
That's it for the upper side
Connect the brake hoses
Now all parts are installed, but we have still to bleed the brake system
Of course you may use the old method by pumping with the pedal
I use a special lid with a tyre valve and the compressor
Fill the reservoir completely
Install the special lid
Of course you cannot use the full pressure, 2 bar is fine
Open the bleeding valve
Apply the 2 bar carefully to the reservoir
We press the air and the old brake fluid thru the system
Don't forget to refill the reservoir during the bleeding
Let's check if the bleeding is complete
Just press the pedal. The predal must have a good resistance
Clean all surfaces which have been in contact with the brake liquid
I use my special method
At the end I install the wheels
Don't miss the hub cap made out of plastic
Remove the stop-blocks
Finally I fasten the wheel bolts with 90 Nm
Fasten the bolts in a cross pattern
Check the level again, it must not be at maximum, we haven't installed new rotors or pads
This repair is finished
With the polyurethane bushes it will drive like my Porsche with M30
Bye, Bye! See you in our next video
