Jeremy,

I tried the lockright on a GU, it was OK but in the end I replaced it with an ARB air locker, it is horses for courses and this may start a war, I believe the lockrite is more proactive as it is always engaged and it only disingages around corners but, it was a pain with the auto hubs and put too much pressure on CV joints and steering.

Since the replacement to the ARB the diff is open as original but can be locked whenever I want...

Thanks Will, can you feel the lockrite thru the steering offroad in low/4 and high/4 and i`ve wondered does it unlock when doing a slow turn in low range,say abend in the track while crawling up a slipperly climb.I would have an air locker anyday but might blow budget....lockrite much cheaper.....horses for courses???could you elaborate Will...

Jeremy,
I did the same, cheaper... in the end it cost me more money.

Just save up and get what you want.

Horses for corses, you get what you pai for, yes it abends, it pulls carries on and I did not like that pressure on CV joints.

IT does unlock but it takes some mighty pressure before it does.

I used it on two trips before I was convinced to take it off.

I have Lock Right on my Cruiser but feel that it's less stress on CV joints as I rarely use 4WD now as opposed to pre lockers. I'm not criticising or arguing (lets call it a healthy debate) but just trying to give my 2 bob's worth to Jeremy. I have free wheeling hubs though and perhaps this is the difference. Would be interested to hear someones opinion on that.
My lock rights have seen 3 years use in Pilbara & Kimberley and to date have caused me no problems at all. I would prefer air locker in rear though but not unless lockers give way.
I managed to get a set of front and rear Lock Rights for under $700 so the savings have paid for a heap of other goodies.Coops

Coops,
Off course if you don't use 4wd the thing does nothing...!!

I use 4wd often and as such posted my experiences. That is why I said, horses for courses.

At the end of the day it is your decision.
A friend of mine has the lockrite in his GQ and he reckons is fine and he uses 4wd as much as I do.

Just opinions and preferences.

I still go off road - just don't use 4WD as much (unless stuck) as lockers help quite a deal.
I will admit to being influenced by cost factor but thought it was worth a try. So far I'm happy enough.
Beauty of this site is no-one is scared to offer their opinions and preferences and it allows us all to make educated guesses when purchasing that new bit for our fourby's.
Happy Camping

I chased around for hoses and belts and could only get them from Nissan. I rang repco and they said that the vehicle was to new and nobody had made aftermarket hoses and belts for it yet.
The prices are as follows:

Top hose $70.98 plus GST.
Bottom hose $52.86 plus GST.
Serpent belt $84.27 plus GST

Shop around i got different prices from different dealers.

Jeremy,
Fuel filters a breeze to replace (in theory) no special tools, just drain the filter then unscrew it from bracket. Then unscrew drain tap, screw it on to new filter, screw filter on to bracket and then prime/ evacuate air via pump on top of bracket. Simple! However, when doing mine I had to resort to removing the bracket (with the filter attached) which meant ondoing the in and out fuel lines, in order to get enough leverage on the filter by placing the bracket in a vice. Not too difficult just a bit messier than the thoery! I would difinitely carry spare fuel and air filters for a decent trip away.
As for a lockrite I've had one on my GU, and previously GQ, since 1991 and they're excellent. Someone else asked the same question a month ago - suggest you do a forum search for lockrite for other comments. Happy travels!

I had to do the same thing on my 4.2TD - take the whole thing into the shed and put it into a vice to unscrew the filter, hope this is not normal practice 'cos I don't carry a vice in the bush.Kevin - sitting here, thinking of there

Remember it may also take more than 1 filter change to clean the system..

mate at the cape they got a bad batch of fuel, stopping every 1 hour to clean them!

6-8 filters later, and having phoned ahead to order another 12, they were going.... They ended up dumping the complete load of fuel, jerrys and full tanks the lot.

Jeremy.
Just a suggestion, if you are concerned about bad fuel you could do what I have done on several vehicles and put an electric pump and a cav filter [ $5 replacment element] between the the 2 tanks so that as you drive you can filter the fuel by pumping it back and forwards between tanks. the factory filter lasts a very long time [270k and still going] so the cost of the pump and filter [$35 pump $60 fiter asembly] is covered by the savings on factory filters.

Sorry I can't remember the filter speck and its not on the carton but it was better than the factory unit. The cav filters are supplied in a range of microns, the housing and the $5 units are the ones used on fergy tractors, Eric.

I already use the CAV filter setup but as you say no specs available. I was hoping you might know to answer another question.
I may try the system you described earlier as my LR tank can sometimes have fuel sitting in it for a couple of weeks before it's used.

Ronnie,,just a little worry on that (lucas filter).....a lot of info i`ve found out from other people on this site is that after market filters on the 3.0lt td may affect your fuel pump life....ie..the aftermarket filters have a higher restriction to flow and i am told the 3.0lt pump is lubricated and cooled by the diesel supply itself.Several guys strongly advise sticking with the factory unit....look back atprevious posts but feel free to correct me if i`m wrong...also consider warranty cover as the pumps are worth 3-5 grand

Jeremy, Interesting thread, so thought I'd comment. A neighbour has a 2002 3L Nissan, and he was strongly advised to fit a CAV filter as a primary filter, to reduce the fuel pump problems, that were appearing in earlier models. Don't think he would have done over 20K yet, but no dramas. The advise came from his nephew, who throws spanners around for a central coastal Qld dealership.

Advise from a diesel engineer? was when changing filters, preferably do it well before you need the the vehicle, say overnight, or half a day. he suggested that the filter element has time to swell, to become more effective. As mentioned previously, dirty fuel often needs tanks drained, and flushed out. Fuel from 44 gal drums is notorious for contamination.
Hooroo...
