Instruction Manual Control Arm Spherical Bushing Assembly
2003-2017 Dodge Viper Spherical Lower Control Arm Bushings
Overview:
The OEM control arm bushings are rubber which deteriorate as they age. The
softer bushing can cause variance in handling response on track even when new.
In addition, rubber bushings are not free rotating and therefore have a
preload when installed. Replacing the rubber with the spherical bushing allows
for consistent, smooth, low friction movement without deflection or
deterioration over time. In addition, the bushing monoball can rotate to
accommodate for freer suspension alignment. The result is improved cornering
and braking consistency on track equating to more reliable handing response
over the lifetime of the bushing.
Compatibility:
The bushing assemblies are available for any 2003-2017 Viper lower control
arms.
The bushing assembly replaces the factory rubber version without modification.
Construction:
Cadmium plated 4340 steel, aerospace grade spherical bearing with PTFE liner.
Anodized aluminum cradle with seals to prevent contamination. Lower friction
joint than OEM.

Installation Guide:
Remove the control arms from the frame. Refer to the service manual for
control arm removal. 
Once removed you can use a press or large vice to remove the control arm
bushings. Mopar also offers a tool to accomplish this.
OEM Rubber Bushing Removal Tips:
Note: the metal lining sleeve pressed into the control arm should not be
removed from the control arm, only the inner steel and rubber pieces of the
bushing as shown. 
Remove the steel end caps of the
OEM bushings by prying them off or clamping them in a vice and pulling them
out of the assembly. These are pressed into the bushing center shaft.
Once the ends have been removed you can press out the steel bushing shaft
center. A tapered socket of the correct diameter works well. Support the other
side of the control arm with a large diameter and depth press tool if using a
vice. Press from the inside of the control arm out since this is the direction
the rubber will need to be pushed out as well.
Use a larger diameter socket to press out the rubber bushing in the same
fashion.
Take care not do damage the metal lining sleeve pressed into the control arm.
Spherical Bushing Installation:
Clean the inside sleeve on the control arm and check for any damage.
Remove the end cap and double check the assembly of the cradle halves by
ensuring the spherical bushing and seals are installed. Remove the steel
bushings for installation.
Press the two halves together for insertion into the control arm. 
Double check the gap between the halves on each side to assure it is uniform.
Press in the aluminum component of the bushing from the outside. The larger OD
flange hould be on the outside of the control arm. The bushing should fit
tight in the control arm and not easily rotate.
Note the halves may not be perfectly spaced if the gap is closer on one side
than the other. (align as possible using a small flat head screwdriver or
similar tool before installing the cap)
Install the end cap retainer by carefully inserting the socket cap screws as
to avoid cross threading them or stripping the socket head. Apply loctie to
each screw and tighten in a star pattern similar to lug nuts on a wheel. This
helps align the cradle halves in the control arm.
Once tightened the assembly should be firmly in place with no play and all cap
screws should be fully and equally inserted into the assembly.
Install the two steel bushing halves by pressing them into the moonball. Lube
the ends of the steel pieces with superlube and press them into the moonball
carefully taking note of alignment before applying too much force. 
Final Installation:
Reinstall the control arm per factory procedures as outlined in the service
manual. After final assembly and alignment tighten the lower bushing bolt to
85 lb-ft.
Inspection and Maintenance:
– Periodically inspect the bushing and hardware to ensure nothing is loose or
damaged.
