Broken Hilux or Prado CV's

[wjw]

I'm getting some rings made up for my CV's but the guys would like to see some broken CV's. Anyone in Christchurch got any? Taking mine out on Thursday to give to them.

Cheers,

Bill

Hi Bill,

What are you getting done? I would be quite interested in costs etc. Have you broken one?

Hi Bill,

Yup have broken one... Am getting rings made up to go round the outside of the CV. The other thing I was told to check is the alignment of the front end... based on these specs:

Alignment specs: solid axle type

Camber: 1 degree +/- 45'
King pin inclination: 9 degrees 30' +/- 45'
Caster (unloaded): 2 degrees 15' +/- 1 degree (pick up, 1985 manual)
1 degree +/- 45' (Land Cruiser -J 4_ series)
1 degree 05' +/- 45' (Land Cruiser -J 6_ series)

Toe (radial tire): 1 +/- 4mm (0.04 +/- 0.16 inches) inspection std.
1 +/- 1mm (0.04 +/- 0.04 inches) adjustment std.

Toe (bias tire): 4 +/- 2mm

Turning angle: 29 - 32 degrees

Wheel Steering Range: inside wheel 30 degrees 30' +1 / -2 degrees
outside wheel 29 degrees
at 20 degrees: inside wheel 20 deg. 30'
outside wheel 20 deg.

Side Slip: less than 3.0 mm/m (0.118in./3.3ft)

NOTES: The bit about "inside wheel" and "outside wheel" refers to the wheel
location when the wheels are turned. For instance, the inside wheel is the
one that is pointing in towards the spring (ie: in a left turn the inside
wheel is the right side wheel). The measurements are taken from the front
of the wheel, they must be measured accurately so it is probably best to
have a competent (computerized) alignment shop do it.

Anything outside the specs above causes extra stress on the Birfields as they are moving outside their tolerances.

How early Hilux can it be?

[Jerry]

Are they the same as 70 series cruisers????? if so can get some broken ones , I would be keen on a set of them as well depending on price......are these for standard CV's?

Hi Bill
You have got me confused completely. Your Prado should have the CVs with the strenghtened ring already which are stronger than the Hilux ones. So how can you fit a ring and still fit them into the swivel housing ?

Cheers Richard

Maybe it's a small flat ring that fits in behind the one that's on the CV to beef it up

Exactly.....it's an old hilux trick, can take quite a bit of refining with an angle grinder for them to fit after the ring is welded on....AND STILL TURN
My suggetion to you Bill would be to replace the exsisting with STD as you will only transfer the stresses to somewhere else in the drivetrain...........and try lifting your foot off the gas when either of the front wheels become airborne, they break as it lands
And thanks for the ph call regarding above, appreciated but won't be required......(I hope)

Have been doing alot of reading and should be able to get them on without affecting the steering. Mr longfield sold Toyota CV's with rings on initially, then did his normal treatment thing. The guys who are doing it have some other ideas though, hence needing the broken CV's. They need to see how they have broken.

As far as breaking something else... we'll see I'm sure I will but hey it's all fun isn't it?

Hi Bill
I run the same CVs as the prado in my cruiser diff. I have never broken the outer part ,but have broken 2 axles and cracked the inner part of the CV on the axle , so as Tim says it mighten solve the problem .

Anyone thought of makeing a fuseable link, like removeing a couple of spline teeth on the freewheel hub sliding clutch dog.
I think Warn do it to some hubs for Jeeps.

Hi Bill, this is not meant to be a get at Bill post, I see you have been doing your home work with the wheel alignment specifications and your advice to have a competent (computerized) alignment shop check it. This is all well and good but once it's been checked how are you going to adjust it ?, there is not much you can do to make changes. Once upon a time chassie and wheel alignment was a separate trade and the components that didn't have adjustments were put on a jig and manipulated to there correct specifications. There are a lot of businesses advertising wheel alignments now days but very few that can actually correct any faults. The slip ring on the CV's to give a bit more strength is an old trick that was used by the early Cruiser and HiLux drivers.

FITZY.

We use the driveshaft as a fuseable link as it is easy to replace or make a new one on the track. If the axle becomes and issue, it will be time to look at chromalloy jobs Bill. If the plan is to have a weak link in the chain, then my suggestion is that you form it in an "easy to get at and repair" area. Pulling axles apart on the trail is no fun (is it Hiriklux?)

That is indeed true, I can't really justify getting it adjusted after every trip. So we'll set it up as best we can and hope for the best. I'm planning on running one side with the ring and the other side without and see what happens...

Having a fusible link in the drivetrain has been discussed many times, I think it's up to the owner of the vehicle to decide how they want their truck to break when the inevitable happens. Me well... it gives me something to do outside of work that doesn't involve the house or kids... So I'll keep going and if I start breaking diffs you can all say I told you so

Al had those warn fusible hubs on his terrano and from what he was saying the other day, they didn't work ;-(

driveshaft as a fuseable link

So how did you do that? Surely once you have longfields in the front, the next weak point is the diff?

[rokhound]

Couldn't tell you how it happened that way, but since changing from the lower geared diff heads (which are inherrently weaker), the boys seem to be winding driveshafts off. As I said that is now sweat as they are easy to fix on the trail. Having said that, my POS's last outing spat out an asin hub and chewed the splines off a 30 spline longfield birf, but the spotters were trying to get the front end to do shit it was never going to do, and the torque multiplication of the 5.0ltr, auto and dual transfers blew the hub to bits

Yeah I'd blame the spotters too

So what ratios are people running?

What do you mean blame the spotters, and I don't see any in front of ya.......surely it was capable of this

[rokhound]

it wasn't the going forward that did it, if you look just behind the passengers front wheel you will see that the rock ledges out. When I went to back out the wheel was just jamming under instead of climbing over that rock.

And any way Tim, would you stand in front of me?


I am running 4.56 ln130 diff heads in mine Bill. I used to run 5.29's and never had a huge problem with them apart from the Yukon R&P set I had that came loose at the pinnion nut end (not a product fault I don't think), which then self destructed the inside bits

[Chopper01]

I'm running 4.56 diff heads in my pos and have had no problem's with them . with my front locker I did blow heaps of cv's but a set of longfields fixed that

[hosehustler]

Hi bill,
had 5;29, going to 4.88's in the new clubby

[Bulletproof]

I'm still confused Bill . Why is the thread called Broken Hilux or prado CVs ?

To me they are two totally different things. All hiluxs and cruisers up until 1990 had the same CVs which are weaker and totally different from your prado which has the same as the latest cruisers.
Which one are you going to put a ring on , To fit a ring on a prado one would mean die grinding the swivel housing to make it work .

Cheers Richard

[Chopper01]

you should not even bother just buy longsor some other crome molly axels and cv's
a mate of mine just scored a set for his prado from a wrecker and paid $650 for the front and rear axel and the rear one has a locker farken lucky #### but they are out there you just need to look

[niblik]

*cough* hub gears *cough*

[wjw]

I'm still confused Bill . Why is the thread called Broken Hilux or prado CVs ?

Because they are similar and the guys who I've given my new ones to want to have a look at how they break, one of the guys there used to make them and is wondering if there is a better way.

Thats not what I've been told.

And as far as longs go chopper, they don't make inner axles for the prado so it will cost me $$$'s to get some made/adjusted.

Longfield also make a chromoly CV that has a 27spline inner and you can put them straight on to the Prado axles, in fact Hiriklux has a set he may do a deal for ya as I'm pretty sure he wants a set of 30splines.
I see they are on special $205 US each

Hi Bill
the" longs" inner axles made for the 90s onward 70 series landcruisers should be right for your prado. I Run KZ CVs and axles in my landcruiser diff.

Hmmm. I've been told they won't fit as the diff offset on the prado is slightly different to the cruisers. I'll have to have a measure up and send the details through to Jafa...

Nigel Harris at lineside sent me KZ prado ones for my cruiser diff and they measured the same.

Give Nigel a ring
