How do you replace a front suspension spring on Renault espace as it appears that the top of the shock etc is under the dash?

There is a cover secured by 4 bolts located at the top of the shock absorber directly under the windscreen wiper arm. Remove that then you can access the 3 nuts that secure the shock absorber top plate at the top of the shock absorber. Support the shock absorber while undoing the 3 nuts after undoing all the lower bolts ( at the caliper / disc end). You may have to disconnect one side of the disc to allow it to swing for access. Use the proper spring compressor tools (spring under extreme compression!) to compress spring to allow for removal of top 3 bolt plate so to change spring after removing shock absorber from vehicle. Assistance probably required to help locate the top plate / 3 nuts on refitting.
