Arrow Automotive Inspection Service...
The Frame, Chassis and Uni-Body
Arrow Automotive Mechanics: Are
trained to inspect body sheet metal, frame and chassis or uni-body
construction during the state inspection
service. We look carefully for any possible cracks in frame, rusted
mounts, fuel delivery lines, brake lines, steering mounts, shock and
spring mounts. We also inspect potential rust damage under the uni-body
chassis, where welds can become weak and cause structural failure.
construction is unique because it requires the
chassis to be precision built around a non-frame based vehicle. This
construction may, over time become weak as welds are challenged by
daily vehicle use and harsh weather related driving.
It is important that uni-body vehicles remain road salt free
underneath the body. The salt can attack welds and over time,
destroy the support mains along the side body panels. This is
especially true when it comes to mini-vans and sport utility wagons.
Body on Chassis
vehicles, such as utility wagons and light duty trucks are built
onto a frame. The CAB or CABIN is generally mounted to the chassis
large rubber mounts at all roll points. The FRAME is a complete
rolling chassis prior to body application. This creates a heavier
vehicle, but a more rigid vehicle. The frame inspection requires a
total investigation, however it remains as important if not more so
than uni-body designs. Most uni-body vehicles are front wheel
driven, while frame vehicles are driven at the rear. The image shows
points that our technicians inspect for rust or cracks. These points
are located at high stress areas along the chassis. On FWD vehicles,
the forward frame horns can crack and cause poor steering control.
These units can be repaired. The components shown in
are readily available parts.
frame and chassis inspection includes:
REAR: A complete
inspection for rust, cracks or torn shock and spring
mounts.This includes all lines, hydraulic, brake and fuel. Gas tank
hangers, exhaust brackets and body cross members.
inspect for all steering brackets, motor mounts, cross-members
and transmission mounts. Steering mounts, shock and spring seats. Upper
control arm mounting points.
On UNI-BODY vehicles we inspect for rear axle
hangers, shock and spring mounts. Gas tank mounts . All
fuel and brake lines are inspected. We look for excessive rust at
sub-frame points along the cabin.. Up
front we inspect the engine cradle. Most all axle components are mounted
to this assembly. We look for
cracked or worn engine mounts. We check all shock and strut towers for
rust and cracks.
Note that this complete look-over is also done during "steering and
suspension" inspection. This vehicle
review is done on all vehicles, auto, utility or light and medium trucks.
Rust is a bust !!!
All our technicians are trained to
inspect under-side body panels. Each vehicle has it's own unique
"rust foot print".
Al's Garage has a
local repair facility where, minor floor board and body side rust
repairs can be completed. These repairs are made using the same
material as original vehicle design. Floor panels may be replaced or
fabricated and bead rolled for strength. All panels are welded into
the floor using state-of-art welding practices. Body panels around
wheel wells, quarter panels, fenders and core supports can be
replaced or repaired. Damage levels from road salt and rust must
first be evaluated and estimated by our body technician. We then
estimate the over-all repair and offer you a solution that will fit
general we use the rule-of-thumb method. These repairs, as shown
here, would cost the owner-operator about $150.00. This floor board
repair on an F150 not only saved the owner money, it allowed him to
operate the vehicle for several years thereafter. This floorboard
repair was completed under safety inspection laws. Open floors must
not allow exhaust emissions to enter the cab or cabin area of a
