So, what are compliance washers for?
If you look at this area at the rear of the MGF.
Pointy Man
The big bush gets worn and you can end up with this.
A close up showing the gap.
OK, but so what? Well that gap means that the wheel can move back and forwards in relation to the subframe. This means that you get a worrying effect of rear wheel torque steer.
In English,
the car will pull to one side on acceleration and pull the other way when you lift off.
So if your car is exhibiting this, check the gaps where the Pointy man is indicating!
You can replace the bush with OEM or with a poly bush. You can also use compliance washers to take up the gap to remove the rear steering!
AdamElphick has produced a very good 'How to' where he completely dis-assembled the bush.
Here is how you can do it without taking the car to bits.
You'll need washers made to the same dimensions as Adam's. I used a handy piece of material that is only 1.5mm thick, so I needed two washers each side of the bush. To enable the front ones to fit, simply cut a section out of the washers. Here's Dave (Tatts) producing the washers for his own car.
And here's a full set for one side.
Now it is just a case of removing the 18mm nut and shaped washer from the end of the shaft. Obviously safety rules apply, and axle stands are in evidence.
You can now insert the cut washers at the front. Ensure that the cuts are offset from each other if using two washers.
And the whole washers at the rear, refit the washer and nut.
Now tighten the nut, and lower the car to the ground. With the suspension under the weight of the car, now loosen the nut off again and torque the nut to 100Nm.
