HISTORY AND TIMING
The Warn Automatic Hublock (Model M350) was used on the DANA 28 Axle (Bronco II and Ranger) from model years 1983-90 (through build date
10/4/89). The Warn Automatic Hublocks (Models M350A and M350B) were used on the DANA 35 Axle (Bronco II, Explorer and Ranger) for model
years 1990-93 (begin build date 10/5/89). Starting with model year 1994 the Warn Automatic Hublock (Model M350C) used on the DANA 35 Axle
(Explorer and Ranger) was introduced.
The Model M350 is black and Model M350A, M350B and M350C are argent (white silver) in color. The Model M350 can only be replaced by Model
M350 service parts. The M350C service kits should be used as replacements for the following:
^
M350A hublocks released 10/89 as model year 1990 running change.
^
M350B hublocks released 4/92 as model year 1992 late running change.
^
M350C hublocks released 8/93 as model year 1994 Job 1 change.
When automatic hublock servicing is required for any Ranger, Explorer, or Bronco II built from 10/89 through model year 1993, it is advised that both
hublocks be replaced.
NOTE:
IF AN M350A OR M350B HUBLOCK REQUIRES SERVICING, ALL THE HUBLOCK COMPONENTS MUST BE REMOVED AND
REPLACED WITH SERVICE KIT F3TZ-3B396-B, WHICH ESSENTIALLY IS THE SERVICE KIT FOR THE M350C AUTOMATIC
HUBLOCK. THE CAM ASSEMBLY OF THE M350A OR M35OB SHOULD NOT BE USED WITH AN M350C AUTOMATIC HUBLOCK
BODY NOR SHOULD AN M350A OR M350B AUTOMATIC HUBLOCK BODY BE USED WITH AN M350C CAM ASSEMBLY.
For model year 1994 (and beyond) 4X4 Rangers or Explorers, replace automatic hublocks in accordance with the automatic hublock Service Manual
procedure and additional diagnostics procedure outlined in this TSB.
IDENTIFYING AUTOMATIC HUBLOCK MODELS
A stamped code found on the rear of the automatic hublock flange face can be used to identify the automatic hublock type, in addition to the model year
summary described above. Examples of the three (3) different codes which correlate to the automatic hublock model type are outlined in the chart:
