This is my first post so go easy...

I have a 2002 F150 Supercrew Lariat 5.4l....

Long story short, I need to replace the o2 sensor on the Bank 1 Sensor 1.
My question is which side is that on? I know its before the cat, but on the drivers side or the passenger side? Thanks in advance...

 

Passenger's side.

 

.. and a real PITA to access if 4 X 4. Go in through the wheelwell after safely removing the wheel and liner.

Thanks.... Yes it's a 4x4, so thanks for the PITA warning.... It figures....It's like 15deg outside, I am in anchorage. I plan on doing the job here in a few hours so I will let you all know....

 

JOB DONE!!!

I had to remove the passenger side wheel to get access to it and the stooopid special socket the parts store talked me into buying didn't do me a bit of good. I completed the job with only a 7/8 combo and small flattip. The hardest part was disconnecting the wires cause it was up in there and kept moving around. It took me about 1 1/2 hours to complete, probaly because it was my first time. Thank you for helping...

 

The tool looks like this for these trucks -

 

The back 2 were very easily accessible, but the front 2 are so crammed in there that I dont think that tool would work with as little space as there is. But thanks anyways... hopefully I won't have to do that again for a long long time...

 

Do it the hard way, I don't care. Everyone I know that uses that tool has NO problems - especially on the passenger side. I wouldn't expect you to know jack, but don't knock until you try it. The 7/8 or 22mm have stripped O2's in the past. This tool slides directly over the passenger side O2 sensor thru the passenger side wheel well allowing you to attach a breaker bar to it.

You don't know what your talking about. This is the tool for the job.

 

edit

 

wow... are you serious? You flew off the rocker on that subject... I never meant to come across the way you obviously took it. I know I am a amature and was simply stating my opinion and I know I don't know jack, otherwise I wouldnt be here asking for help. But thank you for pointing that out and acting like the true professional you are. G'day

 

I wouldn't have posted something that does not work . If you came here to learn, - Don't think - listen.

 

ok, So....Don't think, just listen? Because this place has nothing to do with thinking for yourself, because apparently you know everything there is to know about everything. I got it, from now on I will let you handle everything....thanks pal

Didn't mean to make you mad to begin with but, I guess if I was a "tool" I would have gotten mad also...

 

I ain't got a dog in this fight, except that for the longest time, I never owned any kind of special O2 sensor socket or wrench. And I do this stuff for a living. I used a 22mm open end wrench on just about everything, until I took on a new car line at work that requires the socket, since the sensor is recessed slightly into the exhaust manifold to where a combination wrench won't fit on it. I still use a 22mm open end wrench on just about everything Ford.

There is no ultimate right or wrong, IMO, it's whatever works.

 

You said this after I post the proper tool for the job. Your telling me that I don't know what I'm talking about.

I couldn't remove the rears on the truck with a wrench - I had to get the tool.

Since then , it's allot easier using the tool. AGAIN - I wouldn't post something that does not work ..

 

I get it... You wouldn't post something that wouldn't work. I understand that, and I thank you for your advice and expertise. I was just simply saying that in my opinion it looks like a tight space but, I am sure if I had the special tool you posted, it might be a diffrent story. What I can't figure out is why you got so defensive/agressive over a comment made by someone who is obvioulsy new here, aren't you supposed to be the pro? Wouldn't it be more benificial if you acted the part...
