I just spent the entire weekend putting on a lift that should have only taken 3-4 hours. I guess it didn't help that every bolt I tried to take off was siezed up. O yeah, and the rear upper shock mount bolts all breaking. That was fun. At least its done and now i'ts ready for WF!
Install time never accounts for rust and breakage. Figure even the newest XJ is 9 years old and in the Midwest...that means snow, salt, etc. At least you got your stuff lifted!
