GQ CV's

[Cheezy4x4]

Ok there's alot of talk about GQ CV's being ez to bust, what I want to know ?? Who has themselves broken a GQ CV, how did you do it and what driveline and tires do you run. ??
I have broken only about around 6 and most were with Big power, big tires, front locker in and front bouncing 3 feet in the air.
I think they are strong, and there are not as many brakages as talked about. Ok prove me wrong.

[big red]

seen several go with lockrights, only a couple with airlockers but that appears to be caused by too much lock with busted steering stops, since he fixed that, no more problems.

i know one guy, with just a diesel and 35" claws whose busteed maybe 20 or 30 and another guy with another diesel, 36" swampers, and maybe 10 he's busted!!

That was a classy Pad


I have only seen them break in comps and I am not too worried about breaking much after seeing what sort of canning some of the stock stuff gets......

[Wendle]

I have had this nissan for about 9 months of fairly idiotic driving and havn't managed to pop one yet. I use to break toyota ones running little 33's.
Was talking to BJ about this yesterday. The nissan CV's are only between 1-7mm bigger in diameter (depending on where you measure) and have 1 extra spline. But they are obviously quite a bit stronger.. better design? better materials? better quality control?

[zzzz]

Apologies for hijacking the thread but, any ideas on what a set of nissan axles would cost?
Obviosuly it depends on the type of axle etc.

I thought GQ front axles were fairly weak:

GQ Patrol 88-98 cab chassis rear 1.51" 37spline
GQ Patrol 88-98 front 1.26" 31spline
GQ Patrol 88-98 rear 1.31" 33spline

Toyota 1.31" 30spline
Is that all toyotas? Or are there differences between models? There must be I just don't know the tech info...

Nissan cab chassis rear looks good to me

Can anyone give me some more tech info on axle strengths of toy and nissan axles?

cheers

[bj on roids]

most toyotas, hil;ux and cruiser are 30 spline 1.31"

the cab chassis rear with 37 splines also has a 33 spline front BUT....the CV bells are the same size, although the axles are more heavy duty (will not bolt into GQ front end though)

and singo, it wasnt a pad, the guy who has busted maybe 20 or 30, only lives up the road, has a front ARB locker, and enteres a lot of competitions!

So you are running your TSL's on the 30spline 1.31" axles?
And ruff is running his 38" claws on the same?
And cheezy is running his rig on smallish nissan axles?
snappy snappy?

Do you break the front or the rear very often?
How big is the ring gear in these diffs?
Where do the strengths and weaknesses lie in them?

Just trying to compare all of this to jeep dana44 which is 30spline, 1.31" which has an 8.5" ring gear. Unfortunately we have the dana30 front which is little - 1.16" 27spline.

Good information. Love learning new stuff.

cheers

The nissan stuff is all 233mm ring gear (~9.25") other than the H260 rear which is 260mm "~10.25") and also a full floater, that is the 37 spline job..

Arrgh sorry buddy but when you said 33 claws and a gq I thought you were talking about our favorite tinka bell my appologies. hence the accusiation of padding one beer your way when we meet don't forget.........

[bj on roids]

So you are running your TSL's on the 30spline 1.31" axles?

YES

And ruff is running his 38" claws on the same?

YES (semi float rear is the main difference) and he has 8" ring gear, i have 9.25"

And cheezy is running his rig on smallish nissan axles?
snappy snappy?

39.5x15, SBCpumping here!!

Do you break the front or the rear very often?

front birfs, yes, front axles, yes, rear axles yes, rear pinion, yes

How big is the ring gear in these diffs?

hilux = small
cruiser = less small (compared with dana 60)

Where do the strengths and weaknesses lie in them?

strong crown wont break that shiat, unless the pinion breaks off and goes into it, with well setup suspension, the fuses in the front ARE the birfs, with longfields its the axles, rear, once you sort the floaters, i goes again to the axle

Just trying to compare all of this to jeep dana44 which is 30spline, 1.31" which has an 8.5" ring gear. Unfortunately we have the dana30 front which is little - 1.16" 27spline.

44s, CTMs, alloys, heaps of strength!

the 260 DOESN'T FLOAT sadly...until the GU patrols there was no full floater......and i dunno what resides under the leaf sprung GU utes, but lets just say it looks like the beef (centred rear)

[Wendle]

hhhhmmmm.. You sure about that?? I am thinking that the 260 in the leaf GQ's are floaters.... I am most likely wrong though.

[bj on roids]

im no nissan driver.....but the GQ is semi float type

the MQ/MK is semi float type and right side drop, but narrow track

[zzzz]

I belive the GU and MQ axles are as follows, ahh hell I'll just dump a list I've got. If anyone can fill in some of the blanks that would be great:

Type of axle, diameter (inches), spline count, ring gear diameter

[JK]

Thanks z, that's a very handy list to have.

[bj on roids]

mudcow = 2 spline, .1"

[JK]

Ha ha, yeah but they are the most solid part of the drivetrain... hardened steel shafts and drive cups.

There are splines on the axles into the diff outdrives and on the the stub axles that are about 6mm (0.2361")by about 15-20 splines (I'll check tonight) scales up to 1.77" full scale at 1:7.5 scale

[Cheezy4x4]

How do these people drive to bust 20 to 30 CV's
I am testing some custom CV's ATM, been giving them shyt and so far so good.

I hope these aren't the ones you were running at TTC...

[moose]

going in reverse , full chevvy noise , whilst winching forward !!!!
doesnt count jk !!!!!

[Cheezy4x4]

Yes the same as TTC, and no didnt brake a CV at TTC but did brake a stub axle, the new ones have updated stub axles. Whats the next weakest thing in line. Spose I will find out. ???

[turps]

Since we are talking CV's, I was trying to reverse up a steep hill the other day. Due to some lge ruts in front that would have done alot of damage. And in doing so with the front locker in I think I have broken both CV's (not sure yet the shop hasn't sarted work yet). My SWB GQ is a TD42 running 33muds, and standard gears.

As it turned out that while winching the car side ways I have still done a bit of panel damage so will have to give the insurance company a ring next week.

Turps :(

[RUFF]

Turps this is generaly the time you are most likely to break a CV when reversing up a hill with all the vehicals weight on the front.

Yeah, just ask Cheezy.... (sorry mate )

[turps]

Got my car back yesterday, the damage was. Left CV and Right axle(the little one), luckly they where able to use the right cv so they just stuck it in the left side and everything in the right side is new. Must learn how to do some of this stuff my self as phuck it is expensive, rebuilding all that shit.

[Hoonz]

how must is it to replace a CV?

[POS]

Guys, find out from someone how to change a CV.

Hilux ones take about 20 minutes to change and i'm pretty sure nissan take about the same time.

You'll kick youself once you realise how easy it is to do.

If you do it youself it will only cost you for parts.

If you getting serious and looking at running bigger tyres just buy second hand ones. It won't cost as much.

Also don't worry about all the gasket's and seal's as you'll start snapping them so often, its a waste of time and money replacing these each time you have it apart.

[Hoonz]

how much are cv joints??
helps if I learn to type

[Cheezy4x4]

POS is right, you will kick yourself when you findout how EZ it is to change them. If you have all the tools and practice, you can do it under 10 min ea side.
Wreckers sell secondhand ones for anywhere between $85 to $200 ea.
depending on how hard they are to get .
I am trialing custom ones, up until now we have had small probs, but after 6 months we have finaly got it, just a bit more thrashing with my new tires and we will be selling them. :wink:
