Many thanks tigertim now have a fitting tool and Denso tape.

Couple more questions;

Do you remove the axle u bolts before or after you release the spring from the front shackle?

Should you always replace the u bolts, the car had new springs 3 years ago, where they put new shackles on but kept the original u bolts. It’s a 2007 car with 40k, my thinking is if they are ok just keep them?

In terms of fitting the new spring at rear, is this straightforward or do you have to apply pressure to the spring get it into place? Is that where the string comes in handy?

Many thanks,
Will
