The Fords mostly have problems with the converter rattling inside. This is usually because the catalyst inside breaks down. The only way to fix a converter if this happens is to replace them, probably about $600.00-1000.00 or so depending on engine size (most have 4 converters). Find out what damaged to old converters (check o2 sensors etc) otherwise the new converters may suffer the same fate. Also check the rest of the exhaust to make sure that there is no catalyst pieces stuck in the pipes or muffler as this will restrict the exhaust flow causing other problems.

Look under the vehicle and count them.

Ford F150 can have either one or two converters. Depends on the year and model, I have a 92 F150 Flareside 5.0 and it has 2 catalytic converters. My 03 F150 supercrew has two. One at the back of each exhaust manifold. The one from the drivers side enters a crossover pipe that T's with the passenger side at the back of the transmission on the passenger side.
There are not two catalytic converters. Working towards the muffler from the flange, you have a RESONATOR, a CATALYTIC CONVERTER and finally a MUFFLER.
I would think no way, but also no way would you pass an emissions inspection w/o catalytic converters. Here in Maryland it is a bi-annual inspection.
They have 4...there is two on each side right before the Y pipe!
Mass airflow sensor and or aircharge sensor is bad
Catalytic converter efficiency failure.
Removing the spare tire from a 1999 Ford F150 is simple. All you have to do is get under the truck and unbolt the spare tire.
