AFFECTED VEHICLES

Vehicle Model Year Assembly Plant Build Dates
Transit 2019 Kansas City April 1, 2019 through June 28, 2019

 

REASON FOR THIS SAFETY RECALL

In some of the affected vehicles, the rear axle shaft(s) may not meet the flange flatness parallelism specification leading to possible loss of clamp load on the rear wheel studs. Loss of clamp load can result in fracture of one or more rear wheel studs. If all attaching wheel studs fracture while driving, the tire and wheel assembly could detach from the vehicle.

 

SERVICE ACTION

Dealers are to clean all rust and corrosion on the front face of both rear axle shaft flanges and inspect the rear wheels axle flange to wheel assembly mating surfaces for excessive variation. If inspection passes, recall is complete; if inspection fails, affected rear axle shaft assemblies, axle shaft mounting bolts and wheel lug nuts will be replaced. This service must be performed on all affected vehicles at no charge to the vehicle owner.

 

OWNER NOTIFICATION MAILING SCHEDULE

Owner letters are expected to be mailed the week of June 28, 2021. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.

PLEASE NOTE:

Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $21,000 per vehicle. Correct all vehicles in your new vehicle inventory before delivery. 

 

SOLD VEHICLES

CERTAIN 2019 MODEL YEAR TRANSIT VEHICLES EQUIPPED WITH REAR WHEEL DRIVE, SINGLE REAR WHEEL, 410L REAR AXLE, AND ALUMINUM ALLOY WHEELSAXLE FLANGE FLATNESS INSPECTION

 

SERVICE PROCEDURE

1. Remove the rear wheel and tire assemblies.  Please follow the Workshop Manual (WSM) procedures in Section 204-04A.

2. Clean the rust or corrosion from the front face of both the right rear and left rear axle shaft flanges using a Scotch-Brite™ pad or wire wheel.  See Figure 1.

 

3. Place a standard 2 to 3mm (0.0787 to 0.1181 in) thick washer on the center of the axle flange to prevent a false positive reading.  See Figure 2.

 

4. Acquire a precision straight edge gauge bar, Rotunda Part Number (307-300) and a 0.010 in (0.254 mm) feeler gauge.  See Figure 3.

 

5. Push the straight edge tool against axle shaft flange on one side and attempt to insert the 0.010 in (0.254 mm) feeler gauge on the opposite side to measure for flatness, then rotate 180 degrees and measure again.  See Figure 4

 

6. Is the axle flange convex or does the straight edge allow a minimum of  0.010 in (0.254 mm) feeler gauge between the precision straight edge gauge bar (307-300) and the axle shaft face with little to no resistance?  See Figures 5, 6 and 7.

Yes –  Replace the affected axle shaft.  Please follow the WSM procedures in Section 205-02B.

NOTE: If any wheel studs are missing/fractured replace any missing rear wheel lug nuts and wheel locking nuts.  Reuse wheel lug nuts and wheel locking nuts that are in good condition. If any wheel locking nuts are replaced, all four wheel locking nuts and wheel locking key will be replaced.

No  –  Install the wheel and tire assemblies.  Please follow the WSM procedures in Section 204-04A.

 


21S21 – CERTAIN 2019 FORD TRANSITWHEEL STUD FRACTURE

 

Provide the chronology of events leading up to the defect decision.

 

On July 29, 2019, Kansas City Assembly Plant (KCAP) issued a stop ship for 2019 Transit SRW 410L rear axle with aluminum alloy wheels after receiving a field report claiming rear wheel separation due to fracture of all five wheel studs. This item was reviewed with Ford’s Critical Concern Review Group (CCRG) on August 1, 2019.  CCRG’s investigation found that stud fracture was likely related to flange flatness on certain axle shafts that did not meet the parallelism specification.  A total of eight reports on vehicles equipped with aluminum wheels were identified, all at low time in service: the original wheel separation report, and seven reports indicating fracture of one or more studs but no wheel separation.  Based on statistical analysis reviewed in October 2019, it was believed that field data for affected units would follow a Limited

Failure Weibull analysis prediction of a declining trend. CCRG monitored field data throughout 2020.  A declining trend was noted through early 2020, however an increasing number of reports were received through latter 2020 into 2021.  It is now believed that the declining trend in early 2020 may have resulted from reduced vehicle miles driven caused by the Covid pandemic.  The majority of ongoing reports pertained to vehicles produced April 1, 2019 to June 28, 2019, with customers typically observing fractured studs during routine maintenance or experiencing vibration or noise concerns.  No additional reports of wheel separation were received.  Updated statistical analysis found that aged vehicles continued to exhibit the condition, and that the pattern of reports did not fit the Limited Failure Weibull analysis model as originally expected.  The current field data coincides with a more constant, ongoing failure rate consistent with an Unconstrained Weibull model.

 

On April 30, 2021, Ford’s Field Review Committee reviewed the concern and approved a field action.

 

Ford is not aware of any reports of accident or injury related to this condition.
