COMMON TROUBLESHOOTING QUESTIONS and ANSWERS
Q1: WHY DOES THE BOTTOM OF THE DOOR NOT SIT FLUSH, AT THE FRONT OR REAR?:
A1: LSD door hinges are engineered and designed to compensate for this issue. They are designed to be
installed in the center location of all mounting slots. Some vehicles are different however; adjusting
the location of the swing arm mounts on the door will fix this problem. Mounting the swing arm to-
wards the interior of the door, top or bottom will move the door out; mounting the swing arm towards
the exterior of the door will move the door in. In some cases, the mounting will be slightly different be-
tween top and bottom mounts.
Q2: WHY DO THE DOORS “SPRING” A-JAR WHEN OPENING THE DOOR?:
A2: LSD door hinges are engineered and designed to compensate for this issue. It is common on vehicles
that the left and the right sides are not quite the same. When a door “springs” open there is a misalign-
ment between the swing arm and the ground plate. This can be remedied by increasing the distance
of the “third” point on the ground plate. The “third” point is usually located towards the front of the ve-
hicle. Increasing the distance and angle of the ground plate to the vehicle will release any pressure
and/or contact between the swing arm and the ground plate.
Q3: WHY DOES THE DOOR HITS/RUBS AGAINST THE FENDER WHEN OPENING?:
A3: LSD door hinges are engineered and designed to compensate for this issue. Attaching the LSD hinge
in the center location of the slots and adjusting the magic stick such that the tuff lock is centered is the
optimum desired installation. Making minor adjustments to the “MARA”/“C” profile, the “third” point,
and/or the “Magic stick” should alleviate this problem.
Q4: WHY IS THE WIRING HARNESS TOO LARGE FOR THE ROUTE SHOWN IN THE INSTRUC-
TIONS?:
A4: LSD door hinges are engineered and designed to compensate for this issue. LSD wiring kits are de-
signed for the MAXIMUM wires installed on vehicles. If additional wires are added or modified that
are larger than original, wiring routing might have to be modified. Vehicle owners are responsible
for this modified routing.
Q5: WHY DOESN’T THE GAS SPRING HOLD THE DOOR UP?:
A5: LSD door hinges are engineered and designed to compensate for original door weight, i.e. speakers
and electronics. NOTE: As temperature fluctuates, the gas pressure in each shock increases or de-
creases. Example; in the heat, the gas pressure will expand, in the cold; it has a tendency to contract.
Any modifications to the speakers or electronics may require a larger gas spring. Vehicle owners are
required to purchase these larger gas springs from their local dealer. If you have not modified your
door, your gas spring may be faulty. Vehicle owners are required to contact their local dealer for re-
placement(s).
