Some vehicles in severe service such as continuous high-speed ambulance service operations, or continuous heavy-load operation as in motorhome applications, may experience muffler shell wrinkling/splitting and leakage at relatively low mileage.

TSB 84-6-22 provided muffler replacement instructions on All E-Series Vehicles Except 10,000 GVW and under with 3.07:1 and 3.54:1 axle ratios in noise-regulated areas.

This article provides muffler reinforcing clamp installation instructions when replacing the muffler on vehicles excepted above, that is: 10,000 GVW and under with 3.07:1 and 3.54:1 axle ratios in noise-regulated areas.

FIGURE 16:

To service muffler shell wrinkling/splitting and leakage concerns, a muffler reinforcement clamp, Part No. D9UZ-5A215-A, must be installed on the replacement muffler as shown in Figure 16.
