Cheers I did not realise it was such a big job

Sorry to sound dumb, but what is an impact driver?
I was planning on using a blowtouch on the stubborn bolts

Should i replace the bolts? I need to get everything ready to do this

I did the wheel bearing on the rear of my old golf about 5 years ago, i don't remember it being a difficult job! just lts of grease

are the rears different?
