Question about 1985 Ford F150

1 Answer

Exhaust replacement & Rear Brakes

Ok, so I have a 1985 Ford F150 8 cyl 5.0 ltr 4wd fuel injected truck.

I need to replace the muffler, center exhaust pipe, and rear catalytic converter. I need to know if I can cut the rear catalytic converter off and purchase a universal catalytic converter and just use a clamp to clamp it to the ehaust pipe I just cut it off of or will I have to weld it to the old pipe where the broken one formerly was. If I can not do this would I be able to replace the whole catalytic converter setup without replacing the exhaust manifolds like where would the exhaust manifold end and connect to the catalytic converter exhaust pipe portion. Do it just require a gasket and some bolts will I have to weld it on?

Also if the tail pipe is good condition but has maybe an 1/4 inch of rust where its bolted to the muffler can I just cut the rust part off and move it "down".

I also have a blown rear axel seal what is it, what do it do and where do I locate it? Is this serious enough to warant fixing it or will it just leak and such so I will have to monitor fluid levels. This blown rear axel seal has fouled the rear brakes, drums, and shoes on both sides. I am told that I have to replace all of this. How complicated is this whole procedure?

Will I need any special tools?

I can't see a problem with the converter, but if your in one of the states that does emissions testing it might be a problem as it most likely would leak where its clamped. The best thing to do is get it all on and try to find someone to weld it for you. As far as axel seals, if there bolt in axels unbolt pull out and use the end of the axel to pop out the old seal, and just tap the new seal in carefuly. seals around $ 10.00. Break kleen will clean up break shoes and drumb. Need more help just ask.

Last time. I have Ford focus 2003 sedan dohc 2L. I lost a part from exhaust system. from back to front I see 1. tail pipe 2. rectangular box shaped part? Lunch Box? 3. missing part Muffler?

Starting from the front, coming off the exhaust manifold should have, 1. Exhaust pipe, 2. Catalytic converter, 3. Exhaust pipe, 4. Resonator, 5. Tail pipe. Also, there should be an Oxygen sensor somewhere around the catalytic converter.

Just key in your year make model and engine size.
The stores usually have books that have the pictures too.

Oldie but amazing

You will have to look for aftermarket parts. Use your brain and get creative. The exhaust is better done by the professionals. You're looking at about $300 for the whole exhaust from the exhaust manifold or headers to the muffler. The pipe might have to ordered or they will bend one to fit the car. You'll get new catalytic converter(s), and the muffler you can pick from an endless choice. Go to Advanceautoparts in person and see what they have and how you can use it. If you can weld or know some one who can you can probably save money on the exhaust by getting parts from Advance. As for the rear brakes here are the cylinders. For the fuel filler neck get an aftermarket one that will fit or you can make fit by modifying it. You can use tin snips to remove the old one. And fuel resistant epoxy to install the new one.
