housing mounting flange. These models are now produced with a “Thick Flange” carrier. Models with “Thick
Flange” carriers require the use of longer capscrews at the 12:00 & 6:00 positions. This design enhancement will
have an impact on service parts as outlined throughout this bulletin.
Carrier Mounting Flange Design Change:
The nominal thickness of the carrier to housing flange has been increased. Additionally a much thicker boss has
been added to the flange at the 12:00 & 6:00 o’clock positions. These changes will require the use of new fastener
parts. A new standard 55mm capscrew (P/N 130185) and a “long” 80mm capscrew (P/N 130218) have been
released for these models. In conjunction with the new capscrews, a thicker and larger diameter flat washer
(P/N 130877) will be used as part of this upgrade.

Axle Housing Hardware Kits:
Kit 512686: The new Axle Housing Hardware kit released specifically for models built with the “Thick
•
Flange” carriers. This kit contains the new longer 80mm capscrews and is not designed for models built with
the original design “Thin” flange carrier.
• Kit 511377: The current Dana axle housing hardware kit for the original thin flange carriers will be obsoleted
and replaced by an existing Axle Housing Hardware Repair Kit (P/N: 512097).
•
Kit 512097: The 512097 kit, which includes a “Support Bracket” can only be used on models built with an
original “Thin” flange designed carrier. This kit now replaces the 511377 kits for all thin flange carriers.
NOTE: SOME 23105 AXLES IN THE FIELD MAY HAVE BEEN REPAIRED WITH KIT 512097. THE KIT WHEN INSTALLED,
INCLUDES THE USE OF A “DOG-BONE” SUPPORT BRACKET MOUNTED AT THE 6:00 POSITION. IF INSTALLING A NEW
“THICK FLANGE” DESIGN CARRIER AS A REPLACEMENT, DO NOT USE THE “DOG-BONE” COLLAR ON THE NEW AXLE.
SIMPLY DISCARD IT
AS IT IS NOT DESIGNED FOR THE NEW THICK FLANGE CARRIER.
Carrier Exchange Assemblies:
Any new Carrier Exchange Assembly produced with the new “thick” flange carrier will include new carrier-tohousing fastener parts. The carrier exchange part numbers will not change.
NOTE: With the popularity of the Dana Carrier Exchange program, stock levels of the older design carriers outlined in
this bulletin at OEM PDC’s and DEALERSHIP’S may be numerous. If you have a vehicle that is originally built with a
new style “thick” flange carrier, it can be serviced with an “older style” Carrier Exchange Assembly. The repairing
dealer must simply make sure to use the correct axle housing hardware parts when installation is done.
