Changing A Wishbone
Hit something or had a little crash and best the wishbone?
Sorry for the pictures and the vagueness of it all but this was cobbled together
using pictures and info sent to me a long time ago. I will update it when I can.
Jack up the car on the affected side that needs changing. Remove the wheel.
It also helps a lot to remove or lower the front undertray.
Using a pair of 18mm spanners, undo and remove the anti roll bar bolt.
Remove the flange joint bolt from the end of the wishbone. (40Nm on refitting).
Use a puller to separate the joint from the wishbone end.
This can be bought from smart using the following code. 450 589 013300.
This shows the drop link to the wishbone, these can rust very badly.
Spray the thread with PlusGas penetrating oil and leave to soak in.
If you can spray all the threads the day before, it makes the job easier.
This shows the underside nut that is usually seized. Replacement drop links can be bought
for about £20. If you do replace this part, it must be torqued to 46Nm. To stop the thread
spinning as you tighten up the nut, you can place a 5mm allen key into the end. Problem
with that is you can't then get the torque wrench over the nut.
Remove the 18mm nuts from each end of the wishbone and remove the bolts.
This shows the old and new wishbone.
This shows the new wishbone with the nuts and bolts prefitted.
The Torx bolt requires an E18 socket. These should be torqued to 120Nm.
Fitting is the reverse of removal.
The anti roll bar support bolt should be torqued to 85Nm.
