Why do problems come in pairs ?

I think this is going to be the easier fix- driving back from Scotland this afternoon the passenger wiper arm stopped working.

On looking under the bonnet the motor arm has come off from the bottom of the passenger wiper arm if you understand what I am trying to get at.

Any idea how it connects - bolt, clip etc ? 2011 Range Rover Vogue SE

Bacicslly a push fit ball joint - very common for them to wear out

Happened to me, the replacement only comes as a full £200 unit from LR, so I reversed it (one ball joint fights gravity, the one nearest the motor does not), popped it back into place and all was fine for another 10k miles until I sold the car 2007 Zermatt Silver TDV8 Vogue SE - now sold but was a great car!
