Default Front lower wishbone bush removal

Trying to get the suspension arm out the bush but it’s solid and the rubber in the bush is split. So any tips on unbolting this bush as the bolts look impossible with little access ?
Thanks

18mm flexi head ratchet spanner is the best for the job.

I am sure there is a thread that suggests lowering the rear of the sub frame a little. Hopefully someone can confirm or deny this

You can do that, but it isn't required, the rearmost bolt can be undone easily from underneath the car with a standard spanner, the 18mm flexi head ratchet spanner make accessing the front bolt so much easier.

By far the easiest and best method for a job that is "only two bolts!".
(or get in touch with cossiedunc...)

good luck

Hello Robert,

These bolts are tightened to 150Nm and no method is easy.

I found that a 18mm hinged head ratcheting spanner was too short to apply any effective torque. Some folk promote linking two spanners together or using scaffolding poles but this is considered bad practice by manufacturers as well as posing a safety risk. The suspension arm position also seriously interferes with even a ratcheting spanner's ability to turn the bolt head through any decent angle.

After trying all suggestions I found that MG Rover's official method was by far the best. This is to remove the anti-roll bar saddle clamp so that the bar can be moved away from the bolt head enabling a hexagon socket and a long driver to be used from underneath the car. This method has the considerable advantage that the bolts can be replaced at the correct torque setting.
The saddle clamp bolts are small, recessed out of direct vision and may be rusty so patience and determination may be required. As I said, no method is without difficulty!

It is not necessary or desirable to lower the subframe.

Also Robert, looking ahead, it's much easier to remove the defective bush and fit the new one in the correct position (essential in order for the bolts to line up) with the suspension arm off the car.

Good luck with it.

Simon

I totally agree with Trikey on this method there is no need to remove the roll bar as you will just potentially cause yourself more problems

I have used the above and also ball swivel.
1

2

3

4

You could always shape a tool to fit
5

I think S spanner make work also but have not tried one yet.
6

Also use tow spanners together using a sump plug key to join them, which is glued into the one spanner.
7

8

9

10

Lots of methods but it still remains one of the more nasty jobs to do on the R40 if working off ramps lying on the floor on four poster lift i would imagine it would be easier.
