Help fitting replacement hitch damper

Have you looked on Alko's website or YouTube? 

When you disassemble the hitch just take a note of which hole the damper is attached. As EmilysDad says, YouTube videoclips are useful. It's fairly straightforward, really. I replaced the rubber bellows on the hitch last weekend, which is a similar job.

I took it off last week & been waiting for replacement to be sent I have tried YouTube it’s not very helpful same as Al ko web page the damper is inside draw tube so I couldn’t see which hole it was in I am guessing it’s the 2nd one nearest the caravan
