Had a bit of spare time yesterday and thought I would have a go at changing the rear shocks.

Top nut undone, lower nut off....bolt won't turn! WD40 etc, 17mm ring spanner on, boot against it, zilch! No room for a power bar, only had car up on a small trolley jack.

Couldn't find a lump hammer so had to use a sledge hammer on the bolt end where the nut had come from. Several hard bangs and it still didn't move.

I rekon the bolt had corroded to the lower bush sleeve inside the shock mount.

Put it all back together and have a go later when I can use the 1" windy gun on it. Otherwise it's remove the lower arm complete with shock still on it and attack it in the workshop.

Poor design for northern European climate. A U channel which traps mud and cr*p with moisture at the lower shock mount. Destined to seizure!
