The sway bar will still have a bit of tension on it when you have the wheels off the ground. If you put a long bar thru the large hole of the wishbone you can force the wishbone down to replace the strut bolts. The strut bolts will still be problematic. You will need a screwdriver in one hole first and then work with your bar to get positioned to get a bolt in the other hole. I eventually made a tapered bolt for this job. The second bolt is easy to get in once the first one is in. So I put a screwdriver in one hole then put my tapered bolt in the other hole and then put a good bolt in the screwdriver hole and then replace the tapered bolt with a good bolt.
The strut bolts can be extremely rusted into the hub and the bolts can have lost a considerable amount of metal to rust. If you take your time to avoid snapping the bolt you will save yourself a great deal of trouble trying to get the rusted bolt out of the hole. So work the nut and bolt back and forth a great many times rather than trying to give it a huge force and breaking it and still having it solid in the hub. The strut bolts are 70mm M10 with a special hardness of 10.9 and have a fancy nut and bolt only available as an original part. You are likely to need a new bolt or two and they are not so very expensive from the dealer.
