Front Subframe
The front subframe provides rigid
mounting points for the engine,
suspension, and steering components.
The subframe is not normally subject
to wear and should only be replaced if
structurally damaged.
Rear wheel drive and all wheel drive
models differ significantly in the design
of the front subframe.
Removing the front subframe requires
engine lifting equipment to support the
weight of the engine from above so that
the subframe can be removed from
below.
CAUTION!
Removal or replacement of the
subframe may affect suspension and
steering geometry, including front
wheel alignment. Make appropriate
matching marks during removal and
have the front end aligned once
repairs are complete.
