I'm afraid none of the suspension work is easy on these cars, I couldn't even do my rear springs so I sent it to the garage down the road. This video shows you
how to do it, but misses out several hours of swearing.
The pinch bolts that hold the upper arm ball joints to the knuckle are a particular
problem with these cars, Passats, A4s, A6s, Superbs etc. They're a different metal to the knuckle and weld themselves in over time. My local garage took an hour each side to get them out. There are lots of solution videos on YouTube but none are easy and 99% of them are using air tools in a workshop. I wouldn't do this one on the drive, and I'd order 2 pinch bolts & nuts from TPS before starting the job as the old ones will probably need to be cut and broken in two.
Lots of people of the Facebook Exeo group run Eibachs, they look good but I think the front goes too low for where I live so I've put the Sport springs on my SE.
