Synergy 8240 - Jeep XJ Rear Spring Hanger Bracket - Manual (Page 5)

a. Test fit the new spring hanger and grind smooth any other interfering bracketry.
(If welding the bracket on as well, mark and clean the desired areas of the
unibody where planning to weld. The new hanger should fit snug to both the
unibody and the bottom of the body itself.)
b. Note that the fuel and brake lines on the passenger side will need to be slightly
moved so the hanger can fit flush to the unibody.
c. Positioning of the hanger can be done 3 ways.
i. Utilize the hole in the unibody where the old spring bolt went through and
line it up with the hole on the new spring hanger for the spring bolt.
ii. Measure 3.75” from the front of the spring hanger to the nearest body
seam in front of the spring hanger.
iii. The spring hanger should only be able to go so far forward as the unibody
gets wider in front of where the new hanger goes. Position the hanger as
far forward as it can go, it will butt up to the widened portion of the
unibody.
