Assembly Procedure
Update |
|
| We have become aware of a few
customers who have had fasteners come loose from adjustable front upper
control arms. This is a serious concern, please read the following
information to make sure this does not happen.

|
| Due to the circumstances, we
are taking the following action immediately: |
|
- We are currently sending out notices to all
affected customers who have these adjustable control arms.
- We have ordered replacement fasteners and
are sending them to all affected customers.
- We are posting this on our website and on
computer discussion forums.
- We are assigning an engineer to audit web
based forums (not something we do as a routine).
- We are implementing a 24 hour hot line for
any reports involving safety of FFR products.

There are posts on the discussion
forums which discuss loose or missing nuts that are used on adjustable
upper control arms (there are three sets of bolts/nuts that secure the
actual arm of the control arm to the base of the control arm and the
part of the control arm where the ball joint is threaded into).
We became aware of the problem yesterday when customers told us to read
the forums. Jesper published a quick update to address this last night
(October 14, 2003). After some careful investigation and a thorough
review today (October 15, 2003) with tech support and the engineering
team, we are taking the actions listed above. Lets review the
conclusions reached by engineering and our guys here.
Tightening:
First of all we really do believe the fasteners sent are the correct for
the application. Standard engineering charts for these fasteners state
clearly the correct torque specification is 60 ft/lbs. A quick
assumption is that the fasteners were not sufficiently tightened. A
report of stripped threads and assurances of customers that they were
correctly tightened indicate that the wrong fasteners could have been
sent out with the arms. Reports that the bolts do not protrude THRU the
nut also indicate that the wrong fasteners could have been sent. There
is no way we can individually verify each and every fastener since (for
these fasteners specifically) they were shipped from an outside supplier
and THE BOTTOM LINE IS WE SIMPLY CAN'T TAKE THE CHANCE. These control
arms are one of the only parts that we don't order fasteners for
ourselves. They were included with the arms and we think it was a
mistake. We don't want anyone wasting time calling Pole position, we
sold the arms, we are replacing the fasteners ourselves.
We have ordered replacement fasteners to be sent to every customer who
may have these parts.
You can check your control arm fasteners by looking at the bolt head and
it should have three slash marks indicating a Grade 5 bolt. We do not
recommend grade 8 bolts in this application since the part is in shear.
You should check to verify that the bolt protrudes THRU the nut
(engaging the locking nylon collar).
On the older nuts (mechanical locking toothed nut) the 60 ft/lbs is a
must. Once these are put on at this torque they just don’t come off.
The locknut was changed from a mechanical locking toothed nut to a nylon
style locknut approximately one year ago. This was done at our request
as we prefer this style. There is nothing wrong with the mechanical
locking toothed nut but they must be torqued to the correct specified
foot-pounds so that they grab into the surface of the part.
Also note that the correct torque specification of 60 foot-pounds is for
a dry bolt. The number would be reduced if there is oil or grease on the
threads. Please make sure that all of the bolts in the kit are clean and
dry when tightening them to the correct torque.
Accuracy: It is best to use a click style torque wrench, not a beam
style. |

Notes: We are truly thankful to the
individuals who made this known. We would ask for even more help in the
future when something like this happens. We want to try to make it
easier to contact us directly. We are asking the forums to install
direct links for safety items on their sites (to our tech email) and we
are also implementing a 24 hour tech alert hotline.
Above all else we care about your safety. Our cars have logged hundreds
of thousands of miles on the track and on the street. We trust our cars
with our lives and want you to rest assured your safety is engineered
into every FFR part.
If you have any concerns, questions or feel that you don’t understand
this message, please e-mail or call FFR’s tech department at
508-291-3443.
