Bank 2, Sensor 1 O2 sensor going out. I did Bank 1, Sensor 1 no problem, but the front drive shaft is in the way of this one. Is it easy to drop the shaft? Do I just undo the 6 bolts for the front and lower it enough to replace the sensor? What is the torque for the bolts? I tried uploading a picture but could not get past 90%.

 

What does 'going out ' mean?
How do you know?
What is the code or means of Diagnosis?

 

WSM shows marking the flanges before removing the bolts. Just remove the six bolts and pull back away from the flange. Torque is 41 lb·ft [55 N·m].

 

Check engine light on dash. Checked with OBD2 meter said Bank 2, Sensor 1. Cleared the code (I do not remember the number) and everything fine for a while then check engine light came back on. Same thing. This is what happened when the Bank 1, Sensor 1 went bad.

 

Thanks 52merc. It looks easy enough but I decided to ask first.

 

You offered some great answers to the OP's questions, not a bunch of useless questions! Good job!

 

I agree. @52merc is the man! His answers are always on point, direct, and give great advice.

 

Very true, never any useless BS!

 

Just a warning. BE SURE to soak drive shaft coupler bolts in penetrating oil. Especially where the bolt tips go through and stick out of the front differential side of the coupler. The tips get corroded and when you try to remove the bolts they will seize about 1/4 of the way out.

 

Thanks Levi The bolts came out easily but I did see some corrosion on them which I will clean. I plan on using anti sieze and then after install I will put a light coat of grease on the tips.
