What is easist way to access O2 sensor connectors?

I want to replace my O2 sensors, but after sliding under my Jeep and looking at the accessibility of both the sensors and their connectors- how in the heck do you get to them? The sensors are bad enough but the connectors are way up amongst all the drivetrain components. And if they have locks I don't see how you could possibly get two hands up in there to take them apart.

Anyone have any good tips how to do this?

Lots of views.

Anybody replaced O2 sensors that could offer some helpful hints?

Re: What is easist way to access O2 sensor connectors?

This is probably one of the most difficult jobs on any of the WK's. There is no easy way. Some have been able to get to them (small hands) and get them out, some have lowered the engine (remove the crossmember), and some have dropped the "Y" pipe...disconnect it at the exhaust manifolds and the connection to the tailpipe. None are easy and most have said they will never do it again. The only thing I can say is that if you feel like saving a pretty good chunk of change, go for it. Otherwise, let someone else fight it.

Thanks jeepgcoman!

Not what I wanted to hear, but hey- it is what it is. My new O2's are coming Friday, so I guess I will find out. I have a bad passenger, upstream sensor giving me drivability issues so it has to be done.

Re: What is easiest way to access O2 sensor connectors?

Well, I gave it a shot, but was defeated terribly! You just cannot get access to unplug the connectors or wrench on the O2's to remove them on a WK with 5.7 Hemi. The upstream were impossible. So I thought let's try the downstream and was able, with alot of cursing and contortions, to unplug them, but then was not able to get any tools to clear the pipes to loosen them. So I gave up. It's gonna have to go in the shop. The only way I see getting this done is to drop the mid-pipes from the manifolds and exhaust connection. And I can't do that in my garage on jack stands with hand tools.

Re: What is easist way to access O2 sensor connectors?

Sorry to hear you were unable to get to everything. I would be curious (and I am sure others would be too) to know how much they're going to "hit" you for this job. Also, would like to know if there is some secret that we don't know about. Good luck and keep us posted.

Re: What is easiest way to access O2 sensor connectors?

My closest Jeep dealer is 30mins away. I called and got a quote. $530 total to replace all four O2's The sensors are $85 each and 2 hrs labor at $95 per hour. Kinda sucks taking a hit on the parts when I can get OEM NTK sensors for $28 a piece from RockAuto. I already bought two to do myselft before finding out I couldn't. Jeep dealer won't use my parts. Now I'm thinking with only 2hrs labor should I just have the one bad O2 replaced to save some money on parts? Or do them all and only take a one time hit on the labor. What are the chances the other O2's will go bad? Truck has 85K miles.

I also called a Firestone Auto Care center that is 2 miles from my work. They have never done this repair on a Jeep GC and want to put my Jeep on the lift to see for themselves how bad it is. I might take them up on that just to get a comparison estimate. Their labor rate is less than the stealer's and more convenient to drop off and pick up.

Re: What is easist way to access O2 sensor connectors?

If they can do the job (all 4) in 2 hours, they must know something we don't know or have some special tooling. I think you're wise to check around at other places too, In any case, If I planned to keep the vehicle for quite a while, I'd probably do them all, so hopefully I'd never have to touch them again.....or at least not for a long time. Also, be sure to check out their job warrantees on what is covered, and make sure it's in writing.
