UPgraded CV 's and axle recommendation for GQ Patrol

[PeeBee]

I am considering an upgrade to the factory cv's and axle set and looking for recommendations. I read the RCV set-ups has a lifetime warranty, however what else out there have people used? Its for longevity and that odd time when the situation hammers a corner and the extra strength would be nice to have. I have not had an issue with the existing axle/cv setup however they are now at 120,000klm and have turned and swivelled a fair number of times already - anything to reduce the occurrence of one failing at the most inconvenient time I suppose. The selection is about performance as against cost because there is not much difference cost wise between the few CV's and axles as upgrade items.

[Rossco]

Hey Phil, after doing a trackide replacement with a fairly used one will be going some upgraded ones as well. . Was looking at Cal 4WD or RCV which roadrunner have so will go with those I think. . Need to head up to the valley (latrobe) tomorrow so may have to take a slight detour on the way back damitt . . . [emoji6][emoji106] Will also upgrade axle seals and GU lock nut setup too. .

120k is not much unless you're punishing them every day. I fitted some of these: https://wheelersoffroad.com/longfield-nissan-patrol-y60-birfield.html earlier in the year.
No drama, but then, I wouldn't expect any for a decade or two...
One big plus is that they're greasable just by popping off the lock hub.

[MudRunnerTD]

Yes RCV was what I was trying to remember Rossco. RCV or CAL-OFFROAD and near bullet proof. If you are sticking with a GQ front diff then either of those would be my GOTO.

Chromoly, bullet proof. Also use the Trail Safe upgraded inner axle seals for the win.

[MudRunnerTD]

The Lonfields are also very highly regarded but not sure if they have an Axle option or you have to pop your factory CV off your axle. I have snapped an axle twice.

Given the weight of your car PeeBee I would be looki g for a full replacement CV and Axle. Rossco will attest to the fact that when he smashed his it was not a massive hit and she just went Pop. No catastrophe, just Pop and then 3 wheel drive.

Yep, stitch in time philosophy. I will be trying to shed some weight down the track, unsure how the see-saw is going pan out. Its going to a system, axle and cv's. The RCV are in my sights at the moment, will look at the others now - stuck up here until at Least Aug 15 now, maybe longer, so doing the research.

I am assuming you swapped axles as well. I understand the standard CV is 27 spline?

Keen to see what price they are fetching. I didn't see RCV's avail on the RR website for GQ's, only GU's - maybe I am wrong? Make sure you get a thrust block, which is required apparently when running a locker

If you are looking at brand new CVs and Axles from Nissan bhahahahaha then these RCVs are Cheap for thr massive upgrade they offer.

[MudRunnerTD]

Every Comp Winch truck in the country nearlly will be running chromoly CVs and Axles. RCV and Cal Offroad are popular.

Good stuff, my google/ebay search only showed the GU. I dont know what this block is apart from reading it earlier on the RCV and Cal offroad. Its conditional on the age of the difflock and sounds like a thrust washer of sorts. Either way, Cal wont warrant the installation if its not fitted. I expect it to be supplied if I define the kit - not really something the punter might know about? I have enquired what cost PAP have also, and same price but unsure of availability.

when are you heading down there? If they have two sets I might get you to collect them, I will pay for them. I will ask how many sets they have. If only one I will get mine from PAP perhaps.

Will drop in tomorrow hopefully they have two and will grab them. . [emoji106][emoji106]

I sent them an email just before enquiring. If they do have two sets I will pay for mine in the morning and tell them you will collect for me. Just check they give you the complete and correct set as my roadsafe arms were incorrect when Mark picked them up, just a check point. Thanks Ross, will let you know.

[MudRunnerTD]

Top stuff gents. No brainer really. If I start smashing GU CVs then I will 100% follow suit.

Don't forget the Trail Safe Axle Seals gents. They are thicker ans I think have an extra lip.

[PeeBee]

Fuck me it's so easy to get rid of money with this obsession! Rang home tonight and got it in the neck for all the parcels sitting in the study, we'll go out and work 25 days straight x 16hr days and you can do the same, line went dead, might have hit a nerve or three!

OK, just paid for the dearer set with the 300M cv and axle setup. Rossco is picking up mine today when he picks his up. Happy days, but another work front.

If you call half-shafts "axles"...then yes.

I bought as a set, two shafts, two CVs.
Inner end of shafts pushes into factory diff (which I had a feeling was 31spline?) and outer end will not fit up the back of factory CVs.
CV outer fits into standard locking hubs.

Great , I have bought the monster grade stuff it seems. Dont expect to be abusing the system, however it can all be over in a split second when you lift a wheel and it comes back to earth.

Glad to see Rossco, they are pretty well pointless sitting there like that, send me another shot when they are installed and I can get more of a feel if the right one is fitted. Thanks for picking them up.

[MudRunnerTD]

Nice one gents. They are both the same sets yeah? Was there a set with a higher stress rating PeeBee?

[nissannewby]

Better put chromo hubs on the list as well....

It will either be the hub or the diff centre. Easy to kill hubs with lockers and chromo axles/cvs. Genuine manual hubs aren't cheap. CVs are like anything they do wear out and don't last forever. They will fatigue as they get older and become weaker. Chromoly a lot less so and I would expect to last the life of most GQ patrols.

You could try some of those steel strengthening rings on the hubs which would help and are quite cheap.

I run the steel rings, but curious about what constitutes a genuine hub? I bought mine new in 1997, already running free wheeling hubs - are these genuine as you call it or fitted in Australia like the aircon units? I have a spare set of hunts and also the fixed hubs supposedly ex Nissan as well. I take the point that a weak link would be nice in the drive train where it is easily replaced, but not looking to find it!

[nissannewby]

Genuine manual locking hub. Found on 98% of GQs and on most GU Ute's. I know atleast until 2006 this applies. Not AVM and not Chinese knock off's.

[MudRunnerTD]

It is true that you need to define the weakest link and allow for it. Popping a hub is not that big a deal and carrilyung 1 hub that will fit either side for the win. But I uave now smashed a few CVs and also broken an axle twice. Watching Rossco smash his CV the other day on a track with Zero traction swinging off a winch rope ans the wheel lifted maybe 2 inches and Pop it was over. Gentle gentle. First time I sheared an Axle it was exactly the same, Pop and it's over.

I reckon every comp soec winch truck would carry that spare hub to swap out in 5 minutes for the win every time.

MudRunnerTD, I trawled thru the internet yesterday to gauge the actual strength upgrade between the factory axles and hub materials and found this written.

The 4140 material is approx twice the strength, torsion in particular of the factory axle, not including the benefits of removing the stress notch when reducing the axle diameter to suit the 27 t spline, and the 300M material is 1.5 times stronger than 4140. Tensile and shear values are higher than standard alo. The heat treatment is different. The 300m material is thru hardened, whilst the 4140 has a case harden of sorts, either way both are pretty tuff.

[nissannewby]

300M is a modified 4340. Can be 150-190% stronger than 4140. 4140 is more than up to the task so 300M is overkill and unlikely to break.

I believe superior use to make a lot of their arms from 4140 and have moved some if not a lot of their arms to the 300M alloy.

Picked up a set of the trail safe axle seals, noticed a slight weep from one side when last home, will give these a run instead of the genuine units

I know they don’t need it but I hope all those parts come some sort of wiring loom PeeBee - your car needs more wiring

Good deal. You'd be nuts to not run them mate. You are installing New Axles with a New hardened race for that seal. Best to run thr best seal on the new face. Double lipped. Winner.

Looking at upgrading the rear axle Assy. came across a set-up for the GQ that converts the rear to fully gloating with 300m axles, looks the goods, but having trouble finding out if CEM, Custom Engineering Manufacturing are still in operation, no email or phone return calls received, has anyone come across this mob, or know of a comparable upgrade?

[PeeBee]

Ok, ordered the full floater kit, 3months lead time, probably because axles ex USA

[nissannewby]

There is absolutely no need for a rear axle upgrade. It's so rare for them to let go. Usually the diff centre will let go but such a rare thing for a patrol rear axle to let go. They are so big already. Your money would be better spent elsewhere. Prob a lot cheaper to source a coil H260 out of an early 3L GU. Has the bigger axles and is either semi or full floating if a remember right.

Thanks for your considered opinions, it's my money and if I think it's warranted and can afford it, what's the deal? I don't want the bigger pumpkin that comes with the 260 either. It's not about the cheapest option, it's about what meets the brief. Full floater in 233 footprint is what I want, and stronger to boot.

Marks make a full floating conversion for the H233

Word of warning before purchasing these cv/axle sets, ensure that Roadrunner have completed the 'Australian Mods' before they send them to you. The circlip groove is in the wrong location, approx 1mm out of position, so needs to be recut, the axle lengths are 8mm too long, and they need to be cut down as well. The thrust block supplied will do your head in, however for my vehicle it isn't required as long as the axles are the same length as the ones coming out. Rossco had a few dramas with his, mine are yet to go in, just did some intense checking after hearing about ross's issues and believe the information above is correct.
The problem appears to be the USA manufacturer has the wrong length for the axles. For reasons unknown they dont appear to be listening to the feedback, so every set supplied for the GQ needs to be shortened. The mod is executed with a thin angle grinder wheel - yet to do mine, warranty not affected.

[Zakwatson]

Sorry to dig up this old thread guys.. but you all seem to be on the ball when it comes to these axles!

I have a set of rcvs to go in my GU diff. I have had my centre rebuilt with a TJM locker installed but didn’t get the thrust block installed as it only mentioned an ARB locker…

Are you guys running these axles in a gq or gu? And did you end up using the block after all?

All help is appreciated. I really hope my diff doesn’t need to come apart again!!

I am running a GQ with ARB locker. The thrust block, if one was installed originally remained in the diff center. I simply shortened the axles by 8mm as instructed and they slipped straight in. The only thing I would say is the circlip groove ex factory is a bit shallow and the radius sits the circlip high in the groove.
