| Polybushing Upper Rear Radius Arms |
|
I left it a while before doing this, but it made a HUGE difference to how the car
handled – the back no longer swayed around, and everything felt a lot more stable.
From the diagram you can see more clearly the setup of the back suspension. The upper
radius arms we are going to replace are shown in red.

• Before you start be aware that you will need a 24mm socket
It took a good few hours, but I spread
this over a weekend

Remove the rear wheels
Jack up the back and place on axle stands

Remove the stabilizer bar
Jack up the diff, so you
can detach the shocks(don’t need to be completely removed)

Lower the diff on the jack,
but DON’T remove it(unless your jack can go very low!)
Make a note of how the top
of the springs look. The springs aren’t under any compression now, so press down on
them slightly and you’ll feel/see them release.

Then twist them
in either direction about 90° and they should come straight out.

Jack up the diff again
Remove the bolts to release the
radius arms

Once taken out you need to remove
the old bushes

The easiest way is with the void
bush removal tool(some crop up on
eBay for about £20).

This has an outer section that fits
over the bush, and an inner section that pushes the bush out when you tighten the bolt.
When I did this, the bushes on the diff came out in around 30 secs, whereas the ones on the arms
had to be taken to a garage to be pushed out with a vice!

The new bushes come in two parts and
just push in.

I also took the time to paint the arms while they were off the car

Refit the radius arms and bolt them
back up (this is what took ages – moving the jack up and down to line the bolts up properly!)
Lower the jack and refit the
springs(see earlier pic to see how they should sit)
Raise the jack and re-attach the shock bolts
Re-attach the stabiliser bar
Refit the wheels
Remove from axle stands(carefully!)

Go for a test drive and feel the difference!
