You ever figure out what sensor that needs to be moved where when you replaced the hose?

 

It's the oil pressure sensor.

 

I'm assuming you're swapping it out yourself? If so post pics of the process. Will only add to the knowledge base.

 

Subscribed, in for pics of process....

 

This is one of the most popular DIY replacemnt process that was done to a Murano. A lot of owners have performed this process. Look here for the DIY and pictures http://www.nissanmurano.org/forums/.../82-1st-gen-2003-2007/16103-diy-power-steering-high-pressure-line-repair-2.html

 

Looking forward to the writeup. Mine leaked, replacement cost a pretty penny when I didn't want to lie on my back in the snow/slush/muck on my garage floor in the middle of winter.

 

Alright, finished today, wasn't so bad once I figured out how to remove the hose from the top bracket. Took about 3-4 hours, would take 1 hour now that I know how to do it.

What you need:

2 x 49726 (Copper gaskets)

1 x 49720-CC10C (revised hose)

1 x Don't know part number (O-ring for sensor)

2 x Nissan Power steering fluid

Cost about $150 total.

I started on the hose replacement today. I find I am unable to loosen and remove the bolt that secures the hose to the power steering pump. Does anyone have any suggestions to make this easy.

Liquid Wrench?

A couple of heat/cool cycles may help.

Also, a rap on the bolt with a hammer may help.

 

Unless its rusted, it should not be that tight. Double check you are turning counter clockwise. Lubricating fluid let it sit for a while then try again.

Wait, if you mean by torque bar a torque wrench then you are already doing it wrong. Never use a torque wrench to break loose any fasteners. It should only be used for tighening or you will surely mess up the calibration and even the wrench itself. What you want is a breaker bar http://www.harborfreight.com/12-drive-25-breaker-bar-67933.html or a regular socket wrench with a pipe extension.

Agreed all the way around - ESPECIALLY that you should NEVER use a torque wrench to break bolts loose!!!!!!!!!!!!

Using a torque wrench for that purpose will destroy its calibration and possibly damage the wrench.

 

While I guess I'm luckier than many since I'm coming up on 89,000 miles and I'm just now starting the sad PS pressure line trial, I still need to see it through to completing this 'fun' repair. Our '07 has been leaking for about 3 weeks and now the refills are coming closer together like birth contractions. So from all of you who have already done their own repair, what's the best brand of pressure line out there other, than the Nissan OEM? They seem to be about twice the price of the best aftermarket hoses and their poor design is the source of the problem in the first place! Looking on eBay, there are cheapo lines as low as $27 and as high as $100+; some appear to have different designs - all metal, metal w/rubber hose like the OEM, the same plus heatshield covering, etc. Also, how can you tell if the hose has the newer revised design with the sensor location change? I know no repair will be successful if the right part with the right design and fittings isn't used, so please share anything you can to "steer" me in the best direction. Thanks!

 

This was one of the rare occasions where I wish I would have used Nissan parts.
The job in general, wasn't too bad. The frustrating part for me was getting the hose & hardline connected at just the right position and the old brackets on the new hose - at just the right place and right angle. $48.00 for a hose at Napa,
but if I ever have to do it again - I'll cough up the dough for a Nissan hose.

 

My problem with using another Nissan OEM hose is that their poor design is the source of the problem in the first place. If it was better designed, none of us would be having these discussions! And to top it off as most auto manufacturers are wont to do, their OEM hoses seem to be about twice the price of the best aftermarket hoses - go figure! Thanks for your feedback, mosmo, but I think I'd prefer to search out the top NON-Nissan hose for this job. I'm hoping some of the other commiserators that have done their own repairs share their feedback on the brands of hoses they used and their thoughts on them.

 

If this part fails me again, I would use autozone $50 replacement part. The failure comes from the crimped part of the hose ends.

 

Nitely, do you know which brand AZ sells and do you know of anyone who has used their Murano replacement hose? Thanks.

 

Do a search, a member recently did this repair with the said part. Its on the other diy PS hose leak thread I think.
