How do you fix Catalytic Converters for a 1999 Ford F-150 Truck?
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.
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.
The Ford F250 is a 3/4 ton truck and the F150 is a 1/2 ton truck. The main purpose for these differences, is pointing out the towing capabilities for each truck. The major difference between the F150 and F250 is size and power. The F250 has a more powerful drivetrain and can tow and haul more cargo.
