A3 8p rear damper help

[BradH]

Hi. I’m new to the forum so I hope I’ve posted this in the right place. I’m currently changing the drivers side rear shock absorber and I’m really struggling to remove the bottom bolt of the shock to remove it (21mm).

Now I’ve sprayed plusgas onto it and I’m going to leave it overnight and try again but I’m just wondering if anyone has had the same issue...because you have to turn it upwards inside the wheel arch you can’t get anything long in there like a breaker bar to get some leverage on it and I don’t have a powerful impact wrench but it’s that tight I doubt even one of them would get it off.

Much appreciated.

Best way would be to take it to a garage for them to use an impact gun on it to loosen it and then just nip it back up for you to remove later on
