4x4 Isuzu NPS CV Breaks 3 days after diff lock fitted! Was it the beach or the Diff Lock?

That’s a good idea. Thanks

[@wayne1959]

bad luck there guys. I'm an old beach sand miner karl and the number one reason they break, ( we had merc 6x6 trucks) is full lock and full load in soft sand. You are on the right track though by decreasing the steering lock abilities and you can check the approx. amount when reassembling with some bluetac between the axel and cv cage. I just adjusted it until no way the two could touch and apart from some extreme bogged incidents we had trouble free runs. I realise you would be well off the island and on a new adventure now but maybe something to keep in mind. Be safe you two

[@nowhereboundtouring]

Gday Wayne, I just put longer steering stops in, and adjusted it so I could just tolerate it for normal road driving ( u turns etc), so I hope that is enough. Thanks for being involved and commenting, we appreciate it. Cheers, karl

Wow bad luck guys. The silver lining is there are always lessons to be learnt. As an NPS owner something for us to watch out for too as we also have and e-locker and tune. So great Karl is handy and can be a bush mechanic on the road, Chris is the same. Messy job though and Katty such awesome supervising going on there. 😂

[@nowhereboundtouring]

Hi Guys, I really don’t like this lesson….. being extra careful when in 4WD just so something won’t break ( when you are just doing normal stuff) doesn’t sit well with me. We now carry a spare cv. Keep up your blog, Katty likes it & she does supervise well😃 Cheers, karl & katty

Yes. I smashed a CV when I was in my Toyota. I had one front wheel off the ground and spinning when I stupidly engaged the diff lock and it snapped like a kit kat. I learned my lesson.

[@cactus62]

i might be stating the obvious but re the cv... theres a few conditions that i think lead to that destruction. 37 inch tyres... reverse gear...deep sand.. and tune. all that torque has to go somewhere.. those factors add up. The stress factors combined i would imagine, are beyond designed tolerances. like you said, carry a spare and reduce steering angle a little. your fortunate to have the ability to repair it yourself. imagine the costs otherwise. perhaps a lesson for others ? good luck with your continued journey. ive not missed an episode. cheers

[@nowhereboundtouring]

Gday Cactus, Thanks for watching everything, we appreciate your support. Unfortunately it looks like the cv is the weak link ( like it normally is) but just a little to weak for my liking. Oh well, we just have to deal with it. We now have the spare…. Cheers, karl

[@waynelemmon3007]

I broke 3 CVs in a month in our old landcruiser, being stupid of cause. It's the broken bits that lock the steering up. If you pull it apart and remove all the broken bits. Put all the hub back together and you can can drive with steering in 2 or 3 wheel drive to get you out of trouble.

Bit of bad luck with the CV but CV's have one down side, when on extreme steering angles they have a tendency to 💥 if the diff locker is activated.

They're insanely strong! Good Luck 🥂🍻

[@bikerssupportingcountrytow6904]

I have broken many CV joint in my time 4WD tours and so on. What I have found out or cv's the weakest points are in Reverse especially when you turn do not turn ever only go straight back. If you are going forward in 4WD high or low range you don't have any issues in turning. If you have lockers just used the rear to get you through just about anything if you have to use the front it is not meant to turn left or right so you only go straight ahead as soon as clear disengage your front locker it will drive like an all wheel drive. If you have a centre lock lock it and give you 50% Drive front and rear. I used to get all my parts through Sunstate 4x4.and terrain tamer to purchase cv's and rear axles as I used to break them. The vehicle it was in was a 60 series ute modified with a 6.6 l Chevy diesel fully balanced and lightened it was supposed to be my race engine with 600 horsepower 1003 nmt.

[@nowhereboundtouring]

Yes we have done several reviews of the truck and the gear on it.

[@allanhugh2044]

Just a thinking outside of the square thought bubble. The OEM front differential is unable to deliver shed loads of torque to the stuck (or sticking) wheel; you just get bogged. Drive train should be alright. The Torsen differential has a 3-1 torque bias and for every 100Nm of torque the front differential is receiving, up to 75% of that can (will?) be delivered to the wheel giving the most resistance. Drive train may receive a bit more than the OEM design. A completely locked differential should deliver shed loads of torque without any bias, which, within reason, you should be alright with. But you mention a re-mapping (I think) which may or may not deliver more torque, but certainly a change in the power delivery. I'm wondering if the low range first gear and reverse gear factory torque restriction set-up works on a percentage of power, not an actual measurement of power? Drive train can probably receive a shed load more than the OEM design. I feel for you, but with the wonderful supervision of Katty, things can only get better!!!

[@nowhereboundtouring]

Gday Allan, I’m not exactly sure how the torque limits are set up in the factory engine tune, but I do know that they have all been increased. We do now have a lot more torque than standard ( it now drives like it should, but we only have medium tune. There is a lot of trucks getting around with higher torque limits than us). We will just see how it all goes, and we now carry a spare. Lol, she is a good supervisor, isn’t she? Cheers, karl

[@jackbarnes6929]

Too late now, but avoid electronic and air lockers, Torsten limited slip diffs are a better option.

Hi Jack, It depends on what you are trying to achieve.

[@ronbirchard5262]

thinking back 75% of the cv's ive busted i had the wheels turned more then 1/2 way under torque with wheel spin or it was wheel spin and it grabbed.

[@nowhereboundtouring]

Gday Ron, The truck had a very good turning circle, but as you say, I don’t think the cvs could handle it. Just too much stress on them, so I have now reduced the amount the wheels can turn, by a fair bit, which should help a lot. Cheers, karl

They were about 30000km each, but I think that is just a coincidental 👍 both on the same side. I have reduced the steering lock now, buy a lot, so that should help. Yep, you would hope that they would repack the bearings just because they have it apart. Cheers, karl

Sorry mate any axle needs cv joints or uni joints so you can turn the wheels to steer in any 4x4 independent front end or solid axle but solid axles are stronger and normally less trouble as they get more strength and support from the axle n diff housing in rough terrain

You may be correct, it is better to change a CV than a diff or gearbox….. Hopefully we don’t have any more issues. Cheers, karl

[@davidhorsey7164]

That design is a bit weak esp when they use them for fire trucks etc maybe in that situation a ground anchor and rear winch would help to keep the drive train un stressed but I'd think they certainly should be stronger as it's not like you was thrashing it in reverse and a situation where a walk or 5m with a chainsaw would save a lot of hassle n money great show thank you

Wheel chokes 😳!

[@nowhereboundtouring]

On the rear wheel 😉

[@ianmoone2359]

Do you not understand that you cannot have the front diff locked & turn the front wheels as well? Once you lock the front diff, essentially the both wheels are affixed to each end of a solid axle. If you turn the wheels then the inside wheel has to turn less revolutions than the outside wheel to go around a corner. Because with the diff locked that can’t happen, then something has to give. Either one wheel has to slip on loose surface or the axle (CV joint) has to shear, those are the only 2 options. Because the duals rears were “bunny hopping” as they pushed a corrugation behind the wheel, then climbed it and started pushing the next hump to climb, power was being applied to the axles via drive line in uneven pulses, plus you have a power upgrade so overloading the drive train. This exacerbates the tendencies to fatigue the metal in the weakest point which is the end of the splines on the CV joint. If you’d only locked the rear diff and not the front as well, then you’d probably have got away with it. Golden rule for front diff lock, only when the steer wheels are pointed straight ahead.👍

It’s covered here reasonably well. kzbin.info/www/bejne/jqeXf2iKZbRlbtk From about half way through, it covers front diff locks, and towards the end, disengaging the front diff lock around corners. Front diff lock is ONLY for straight ahead / straight back travel. Whoever installed your front diff locker should have explained this to you when it was fitted recently. Just trying to prevent it happening again is all, not criticising you for not knowing, we all have to learn, it’s a lifelong process. Wishing you best of luck with it in future.

Thanks Ian, we appreciate your information. I was aware of the operating characteristic’s and limitations of a front locker. I have had twin locked vehicles for the past 30 + years, and actually had a prototype ARB locker in my vehicle from late 1990. You are correct about only using the front locker for straight ahead travel, as recommended by the manufactures of all lockers. In reality you can get away with it when turning on low traction surfaces. It is unfortunate that our current vehicle appears to have a relatively weaker CV set up than any other vehicle I have driven. I will just have to be careful when I use the locker ( which is the last thing you need, because that’s why you are normally using the front locker, because the terrain is challenging). Oh well.

Well you two, very annoying, but great Karl that you can help yourself and still made it to the SOS station. You can't change anything, at some point the drive parts break down. Especially with the stress, as your heavy paths in the terrain stress the material. Happens with every vehicle. We had the fewest problems on the construction sites with the Unimogs and in Russia with the GAS 66 and the Urals, which went through everywhere and were always thoroughly maintained, especially the drives, transmission and engine. Good luck to both of you. Greetings from Frankfurt

Front diff locks and CV's, never a good marriage. Should never be engaged unless in straight ahead position, but drivers forget this rule in the heat of the moment.
