Whole process took about 3 hours but went well as I had all required tools and some prior experience.

Agree that most difficult part is ensuring that all ribbon cables and connectors are outside logic board

and not underneath it during reinstallation….the antenna connectors were also a bit tricky - I use a binocular

magnifier on my reading glasses and strong work light. Also had air duster can on hand and isopropyl alcohol and cotton buds to clean

up interior of mac along the way - quite a lot of dust inside. Although mac sounds better now with replacement right

speaker it is still not perfect…I wonder whether audio drivers are also implicated in my original problem (fuzzy distortion

on right speaker especially of lower frequencies)…..

Replacement went well - iFixit guide marvellous as usual and replacement trackpad performs perfectly. So good to resurrect

the trusty MB Air!
