Body Structure
Introduction
The standard wheelbase Jaguar sedan has a unit construction monocoque body structure with bolt-on front fenders and
welded rear fenders. The doors feature lif t-off hinges and welded drop-glass frames.

BODY ALIGNMENT
The Body Dimensions Plan, and Body Dimensions Side View, provide specified BIW dimensions to facilitate damage
assessment and location of replacemen t parts. These dimensions must be strictly applied when used for damage
assessment, component location or post repair verification.
• NOTE: The right-hand side is always looking towards the front, from the rear of the vehicle.
The nominated plan view master datums are on the right-hand side of the body with the left-hand datums dimensioned
from them. Right-hand datums must therefore be known to be correct before any other cross-car dimensions are checked.
Datum location, Example
The Front Master Datum (front crossmember rear mounting at the inner face of the main floor RH longitudinal) is nominally
359,5mm to the right-hand side of the body center line. The LH side fron t datum is measured 717,0 / 721,0mm from the
RH. Refer to the Body Dimensions Plan.
Expressed as a true posi tion in three planes, the front master datum is:

Panels centered between two adjacent panels must have equal gaps on either side. For exceptions to this, refer to the
appropriate specification. Gaps between ad jacent panels or components must not expose harnesses, labels, brackets or
visually poor joint or assembly conditions.
• NOTE: Sliding roof panel clearances are specified without the edge seal installed.
Areas of particular concern are, fuel filler flap, trunk lid to fenders and saddle panels, hood to fenders, grill and headlamps,
sliding roof to main roof panel, door gaps at fenders, B\C posts, roof drip rail an d rocker panel, and bumper cover to fenders
and cross car assemblies
Alignment
Panels must be correctly profiled to maintain cosmetic appearance, and ensure co rrect seating of seals with minimal wind
noise. Areas of particular concern are hood to fenders, trunk lid to fenders and saddle panels, doors to apertures, doors to
fenders and adjacent doors and relationship of the sliding roof panel leading and trailing edges to the main roof panel.
Exterior Fitments
Bezels, trims and lamps must be concentric with apertu res and have equal clearances with adjacent panels.
Areas of particular concern are headlamp to hood, fender and trim panel, exhaust tailpipe trim to bumper cover cut-out,
rear lamp assembly to trunk lid, fender and bumper cover trim, and side feature lines including body side mouldings, fender
to door and door to door.
