Alot of people have asked me how I fixed my upper shock bolts on my 1996 Jeep Cherokee ( XJ ). Well I used my impact hammer or Air Hammer and knocked the old bolt out, then with a piece of safety wire and pulled a new bolt through the hole..that’s about it..lol You need 4 Grade 8 bolts 3/8″or 5/16″ x 1 1/2″ long. 4 lock washers and 4 nuts to match.
