Have you read about the problems wih the Bilstein shocks? Several of us had big problems with the rod ends because they were installed with some kind of Euro-locktite. If this is the problem you are having, the only solution is to contact FFR and have them send you new ones. Heating or beating on the shocks will only ruin them. If by this time you did ruin them don't worry, they will still replace them.
Do a search on Bilstein or shocks - this was a big issue in the last two or so months.
Regarding ball joints (upper), I had trouble with one - it almost was like the threads were stripped - but the other went in very smoothly.
