Extremely tight threaded fit. One of the struts began to tear the thread. I was concerned that the installed nuts (probably made of a harder metal) would also be stripped, but that didn't happen. The torx screws on the posts have also started to loosen. Luckily I was able to reuse the originals so my mechanical skills weren't an issue. 2006 Dodge/Ram Truck Caravan 2WD 2.4L MFI DOHC 4cyl
