Hi, first time out this weekend with a lokka and bang went the right cv. It started with the right front hub not engaging 4wd. I could feel the car pulling to the left when accellerating. Few hours later I heard a clunking noise. I am no mechanic but some knowledgable people advised me the the cv was gone and possibly the drive shaft. If I reach under and grab the drive shaft its completely loose. Could the front hub not engaging (possibly not put together properly) have caused the cv to go? I am contemplating replace the other side. I had the scariest/dangerous experience driving down phone track (mt dissa) in rear wheel drive... and towed up the other side. Is it possible to get strengthened cv's? or should new cv's do me fine? do you think i have a problem with weak mitsu drive shafts? Any thoughts/ideas would be appreciated. I am no mechanic but learning more each time I break something :).

This ...um ...Lokka exactly what is/was it , brand etc, and who installed it, because I feel there must have something not right somewhere for it to do that,

Lokka Lock Rite from 4wd Systems (
http://www.4wdsystems.com.au/html/lokka.htm). I had a mechanic/mate install it. The installation was apparently no problem for him but it took some time.

If your right hand hub didnt engage, There wasnt any stress on your right hand c/v, I would strip it down first and then try to see what went wrong.

good point... and now confused about what could have caused it to break. i can feel a lot of metal filings and the rubber boot seems to be chewed up. Could it be that the cv is fine and the actual drive shaft has broken/left go? still, none makes sense so i will take it back to my mate. he suggested the same thing about pulling it apart and seeing what went wrong.

Ask him did he leave a certain amout of play in the system , I think it should be 10% or 20% free play

are you talking about the lokka when you refer to the "system"??? I think I remember him saying that he marked a spot on the crown before dismantling it. Forgive me if i am off the track with this one.

When you fit one of these Lokkas to the front diff (which I have) you need to drive a lot more gentlely, like when you lift a front wheel and your giving it a bit to much juice and this wheel makes contact with the ground again there is quite a lot pressure back on that wheel and some times something has to let go and the cv is the weakest point. I have not broke one yet, touch wood, but a few mates with MUs have.

I have a LOKKA. From what I understand installation is relatively easy for those that know what they are doing, but for those that haven't done it before it can take a long time and it is crucial that it is done properly. that is why I am surprised that they advertise on their website that it is suitable for installation at
home by someone who has basic mechanical knowledge (able to change brake pads I believe!).
I rang quite a few diff specialist
places and only very few of them were interested in doing it. Those that were were almost twice as expensive as for 4wd systems to do it (I live in SA). I went with them because they do the installations all the time. Sorry this doesn't help your cause now, but may be of help for someone else considering one. Don't be put off by the product, just be sure of the installer!

my dilemma now is do i take the car to someone else to verify the install is OK. I rang around some 4wd shops and all said the same thing that its straight fwd for someone that knows and you cant really get it wrong.
maybe it was caused by my driving... previously i needed a lot of momentum to get me through some stuff whereas now I can try and crawl through/over it.
thanks everyone for your
feedback.

Frank you need to identify what is broken first.
Ther are heaps of things that can let go in an IFS front end CV, the splines into the cv, the freewheeling hubs, the drive shaft into the inner cv, even the driveshaft into the diff.
I would be strippin it down but Im a mechanic and this doesnt scare me and I have fitted a few of these lokkas to
mine and mates vehicles. But if you donbt know then you have to take it to someone who knows.
When you say the drive shaft is loose? What do you mean...its spin freely? If so then the problem (cos you have a locker fitted) is in the diff housing itself. It should not spin freely it will turn only if the other side freewheeling hub is unlocked and will still require a fair amount of effort to turn.
I think you have a fair problem from your description and I think it might have started with the vehicle BEFORE the locker...how old is the vehicle and do you know what work it did before you fitted the locker?
Is your mate a mechanic or just pretty skilled....diff work is not something you just have a crack at!
Happy to assist if you can give me more information....
Look forward to hearing from you!
Matt.
