Power steering leaking fluid

Yeah, don't you just love the pricing on some parts?
Fortunately, it doesn't take long for innovative people to find ways around manufacturer rorting, and offer much more satisfactory pricing on replacements.

We live in a global manufacturing world, and so many of these components are made cheaply, new - but marked up beyond belief, when it comes to parts.

The following eBay seller states the NS and NP racks are interchangeable between 11/06 to 2016 Pajero models.

Used Pajero steering rack - eBay

Just be careful buying used - if the component is prone to suffer from premature wear and needs total replacement, then any used unit on offer, is quite likely to be in little better condition, than the one you already own.

Cheers, Ron.

As Ron mentioned I'd be careful with 2nd hand racks you never know the history of the vehicle it came from. A overhauled unit at least you have some form of warranty quality of workmanship.

Twice I have personally been involved with situations involving damage/2nd hand steering racks.

Most recently was prado (2014) left hand side was impacted causing excessive free play so any corners took multiple bites to track around a corner (even on bitumen). The fortunate bit was able to replace the section affected with few hours on hoist cursing and swearing. trying to seal the rubber boot being hardest took both myself and brother to clip up the banjo ring. (similar to hose clamp but locks into place using tabs and then folded over itself

Many years prior folks colt took a collision to front end vehicle repaired but had a knock when turning wasn't cv joints turns out they had replaced steering relay with 2nd hand unit, which was in worse condition than one they binned, if it wasn't for fact brother is a mechanic (apprentice at time) and had another mechanic look at it the car would be in a unroadworthy condition.

Where is the rack leaking?
At at one or both ends or the input shaft?
If the bushes (if fitted) at each end are worn then the rack may require replacing.
Hopefully the rack ends aren't scored and a new seal in both ends may restore the unit to serviceable if the rack shaft to housing, doesn't have too much slop.
They are ony a double ended hydraulic cylinder.
Do you hold the rack at full lock at ANY time in it's life? If you do, you are making the power steer pump create full pressure and then everything internal and the pump & drive belt and hoses all have to run at, FULL relief valve pressure, while it is held on full lock.
That makes the seals have to operate at maximum pressure instead of almost nothing. Doing that wears the seals more and causes leaks.
Just turning the system to near lock and held there is far less pressure than held ON LOCK.

You can get seal kits on eBay for $100 . Would need to get yours stripped down first to make sure no mechanical damage or worn parts.

Sydney spareparts may have one

Or try centralparts.com.au in Perth. They show a listing of a 2013 ns Which appears not to have any impact damage.
Hope you find a good economic solution.

Just to tie up the loose ends here, I got a reconditioned rack from Steering Solutions in Sydney for $650 plus $70 freight to Kalgoorlie and my mechanic charged just under $350 to fit it, including fluid and wheel alignment. It's a good outcome, although I have since discovered a thicker type of power steering fluid that leaks less, allegedly. It might have been nice to have known about that a bit earlier to have tried it out.
