Outer Limits 4x4 Board

sorry not for a project or anything, just out of curiosity.

what is considered to be the daddy of front axles running cv's.
maybe an unanswerable question, but hey.

most of the us ones i've seen are running uj's

from the comfort of my armchair i've read of 101 sals axles having monster cv's and presumably being sals a decent centre, gq axles having strong centres but weak cv's (not sure hwat that's relative to).

what about 80 series axles or gu axles.

thought here would be the best place ot ask, i don tthink they use much jap stuff in the us (not sure i can be bothered with pirate anyway) and most efforts in the uk seem to be put into upgrading of rover axles for some reason, maybe its because we've got lots of them or something.

not sure if i should say stock only, but please feel free to voice opinions on stuff with aftermarket upgrade as well.

Rockwell 2.5T run either Birfs (CVs) or UJs AFAIK...

Yes 101's have very large cv's. These are difficult to get in Aus and the USA, which is why most of us think of other options.

In the USA, where open knuckle, steering axles are popular, then u-joints are used, because of the difficulty of sealing a cv joint from water and mud (also difficult to lubricate). Longfield is making 35 spline cv's for Dana axles now. These use a special seal, and so far have proven to be stronger than u-joints, but are not widely used because of cost.

Most of our vehicles have closed knuckles, so cv's are best. But we push them beyond the original design parameters. Because of the space constraints of the original housings/hubs, it is difficult to replace the cv with anything larger.

If you can get 101 axles, then you will have much stronger cv's than we can even dream of.

Maxidrive makes a knucke to take 101 cv's, but these are very expensive. I believe they are based on the larger series units for external dimensions, but machined to larger dimensions internally to accomodate the large 101 cv. Because the resulting wall thickness is reduced, they use a higher strength alloy steel. There is a lot of machining when you have to start from a solid block (unlike the originals), thus the expense.

Edit:
Toyota 80 and 105 series landcruisers have larger cv's than rovers (apart from 101) and other landcruisers and Nissans before the GU.

GU cv's have larger bells (comparable to Toyota 80 series) but they did not increase the diameter of the stub shaft (which is where they tend to fail). So Toyota 80 and 105 series are stronger than Nissan GU.

I wonder what a 4wd Mitsubishi Canter or Toyota Dyna cv size is? i Think Glen Dobbin is (was) running Dyna CVs in his truck.

For you internationals, Glens truck runs custom portal diffs and 44 inch boggers.

Callum,

Here we are chatting on a forum from the other side of the world when I only live 45miles south of Edinburgh!

Anyway, there are a couple of cars on the UK challenge scene running 101 axles. Are you familiar with Pete Whitman (aka Bathtub) or Bryn Hemming? They both run them and have had zero breakages so far AFAIK. Pete is now running 42" Iroks and Bryn has always run Boggers.

However, Dave Ashcroft has, so far, sorted the problem with his new strengthened CV joints (for standard Rover axles). None of us have managed to break a set yet and they have been tested over the toughest events in the UK this year. The AFC is at the end of August and if they survive that, I think he's cracked it (no pun)! They also come with a 5 year warranty.

Have you been on the Devon 4x4 forum?

you don't happen to have an association with duns and a yellow ibex running d60's do you?

Navigator!!!!!!!!

And they're Pro Rock 60's

JF

Sorry to jump in, but for the local guys I was just wondering what the best option is as I have just done in my drivers side C/V.

I can just replace it with original unit but from what I have herd they are crap!

I am open to all solutions from aftermarket better quality C/Vs, all the way to replacing the diffs form another vehicle possibly something with front hubs.

PS; Please no abbreviations as I speak Landcruiser not Land Rover.

ah, i saw it at the highland show on the redpath tyres stand.

was initially intrigued by the sizeable krawlers on it and beadlockers so went to have a closer look. i presumed the driver was very optimistic or very good to be running rover axles with such tyres. alas on closer inspection, seeing the built d60's and coilovers i didn't feel quite so clever and then saw the outback challenge stickers on it and was well impressed.

was good to see it there, haven't seen many such serious things in the flesh. what engine//transmission is it running?

whereabouts in duns is redpath tyres? my landie had the 'suzu engine installed at a friend of my father's there. bit of a rubbish commute over a couple of weekends, but hey.

i look in occasionally on the devon 4x4 site but it seemed to be used by folks with lots of cash to throw at a problem. maybe i'm being a bit harsh though. i quite like this place as i like reading about more custom or low budget projects. i daresay devon 4x4 is pretty good for event stuff, but as i'm still in the midst a stupidly long degree i cant afford to go out and break too much stuff of a weekend :( i'll have ot remain an armchair off roader for a little while longer.

thanks for the rundown bush, good of you to put things in perpective and provide a bit of info on jap stuff. info is a bit scant on uk forums. i presume patrol/'cruiser owners dont change axles as stock is pretty good and worth upgrading.

cheers

It's running a blue printed GMC 6.2 V8 Diesel with Whipple super charger, mated to a TH400 box then lt230 transfer through a "Mark's Adapters" adapter. King coilovers all round 'a la Rohan Cavanah' , Dynatrack Prorock 60's, 35x13.5x16 Krawlers or 35x11.5x16 Simex or 35x12.5x15 Goodyear Mtrs.

Shame that you're on 35s with all that drivetrain...you should be on 42s minimum...

Sure, unfortunately the Ibex was only designed to take 35" tyres. The 36" simex rub everywhere. It would take some major engineering to run anything bigger. And at 7 feet tall, it's high enough.

And then what you have done is just some "minor" engineering then...

Which model Ibex??

250S King Cab.

Where about in Canada are you??

I'm looking to move to the shores of Lake Huron, Ont.



All that torque just desperate to drive the wheels, however when you have too much traction..........



JF

Calgary. A completely different country than Ontario...

Just make sure the Ibex is somehow registered as mosre than 15 years old so you can bring it.

John, completely off topic, do you know of any good ISUZU parts places in Canada. Having trouble tracking down a 4BD1T manifold.

Also anywhere that would have a Garrett T25 turbo 2nd hand???

Ummm, no. Check with a local (wherever you are?) diesel shop.

are you just looking for your own 110 or have you destroyed one of your friends??

I think the Isuzu trucks are more prevalent in Australia than Canada,

Fortunately, the Ibex belongs to a mate. Personally, I wouldn't thank you for one, atleast not for a comp truck.

No, the manifold was one of the things that didn"t break on the trip from Vancouver-Panama-Vancouver, but Chris (the owner) would like to do a turbo conversion. GMC trucks were re-badged isuzu trucks, which are more common in north America AFAIK.

Phone around to the local truck breakers (wreckers in Canuckspeak) and As I said phone or go by the local diesel shops. Usually the local diesel shops can build anything.

Your on the left coast at the moment?

Have done that already to no avail, the few that can help need an exact part number and a wait of 7-10 days for the parts to come from the US.

Yep, close to the left coast - Abbotsford.
