100 series front diff splice with gq centre

Hi, looking into doing a splice with a gq housing and centre with the front on my 100....
what is required with the gq centre to fix the 100 axles, is the spline the same.
Any info would be great,
Thanks

Front diff

I have just had my 80 series done. Used a GQ Airlocker with 80 series side gears. Apparently there is a bit of machining required to make it fit. Cant say for the 100 series, but the 80 series axle was too big to fit the centre.

Thanks

I believe the differences between the 80/100 series diff centres and the GQ diff centres include axle spline count and the axle centre line is also different. PM 80UTE on here as I know he has done quite of few of these front end set ups for 80's and 100's with excellent results. I think uses a GQ centre into an early Yota housing and the rest is original 80/100 gear.

Cheers ;)

Thats Crazy you could have bought a Solid Axle Dana 60 complete for that sort of money and never had to worry about breaking anything in the front again.

Agreed Tony however some people want to run in comps where diff swaps to a Dana 60 are not allowed.

Yeah I know, but that includes an airlocker and diff ratio's. The actual fab work cost a lot less. About two days after I bought the locker and other stuff a set of D60's came up at the right price. was kicking myself

The 5K with Solid axle includes gearing and Airlocker.

Until recent changes in the rules [Xtreme Open class] they were not allowed. Xtreme class still restricts it to the use of the original front and rear housings and components.

So all the GQ Patrols running are still running GQ Diffs not GU? I would have thought most were running GU diffs.

And what about fester? He runs a GQ or GU front diff in his 80 series.

And really there is no difference in what Pete has done. You cant class what Pete has done as not being a diff swap.

Ps, Im not arguing i just didnt know about this rule.

heaps of cars run in this comp with diff swaps! there was or is a catorgry that MMM was trying that was aimed at standard type cars and as such he wouldn't allow diff swaps. As far as I know they all still run the same tracks, would be something along the lines of the under 3litre class he used to run but with more restrictions to the modifications to the car.

Tony, basically the reason I went this path is to try and keep it semi road friendly and to the eye, standard(ish). I also wanted to be able to run toyota axles, CV's etc etc. As soon as the money tree recovers a little, I will go Cromo Longs and axles.

I did seriously consider the mog option as well, as it would not have cost all that much more to go that path. But at the end of the day, I use my rig mainly recreationally and in some competition. Of late I have been doing less and less competition work so the Nissan/ Toyota hybrid seemed like the logical choice to handle the 38's yet still retain driveability on road.

No worries Pete sorry if you thought i was knocking you as i wasnt. Mogs are defianatly not the answer. But a D60 is no different on the street to what you have now. And as they are usually custom built it should be compliable in your vehicle so it wouldnt matter how stadardish it looked.


Having said all this you would still be a long way from fitting one of Solid axles Diffs after purchase price of around 5K. You still need to set up steering and link mounts which could easily cost another $1500 to do it right.

But for 5K you just wont find a stronger diff. It comes with Gears,Locker,35spline Superior axles and disc brakes and its a high pinion. Yes Mogs are cheap but impractical in anything but a pure comp rig.

PM JOHNZ off this board.

He has done this exact mod to his DX 105 Cruiser. He was talking me through it when I was there getting a cargo barrier and sussing out suspension.

He's over near Enoggera somewhere.

Top bloke to deal with!!!!!!!!!

Anthony.

Sorry. Talk to the guys at Aussie Diffs off Heyter street in Currumbin they will be able to help you out with this. They build custom diffs for a living and are great guys to deal with.

That surprises me. I have seen him do very similar to a lot of other diffs. Truck's,4WD's and car's.

No worries Tony, I didnt see it as knocking but merely constructive criticism. At the end of the day we are all on a learning curve. I was offered a set of D60's without ratios or lockers for $5500 which sounds a bit more than what you are suggesting. as you say by the time I did steering, links etc the cost would have been a fair bit more. Couldn't justify it when I am slowing down a bit on comp work.

Anyway, I think that for what I am doing with the vehicle, this will give me a pretty strong front diff. I'm already running Cromo hub gears and have upgraded the hub studs to 10mm. I have only ever broken one front inner but a heap of standard CV's. Im running nitrated CV's now and they seem to be pretty strong (havent broken one yet, just diff centres and standard hubs). The GQ centre should be heaps stronger. I just hope that when I do go Chromo CV's and axles I dont start breaking the GQ CW&P again since I am running 4.88's

Yeah dont get me wrong. It will be plenty strong. I was just pointing out that for the money you spent you could have been stronger. Dont worry. Ive built lots of things more than once even when i new in the long term strength was going to be an issue but i still built it as i had a heap of the parts.

Im actually about to do it again. And with a front axle just because i allready have most of the parts lying around. But i know in the long Term i will be calling Danny at Solid to order a custom front diff.

5K for what Solid is selling is unbeleivably cheap. 12 months ago you would have payed 10K for a similar set up to be built here in Aus.

I played with Dana front end stuff ( Dana 44 ) in the late 80's and it was ok but a maint pain in the a*s. In deep soupy mud the axle tubes would fill upto the axle seals near the diff centre and if ever you wanted to pull the axle's out there was no way of getting them back in with filling the diff housing with mud. ( complete diff strip down and steam clean)The brakes were crap and ball joint type king pins ??????. I was making bronze bushes for the axle unit's ( before CTM's existed ) and it was still crap. When the 80's came out i soon built a custom front with 80 C/V's for my V8 75 series and never looked back. If longs had been available then it would have been an easy fix just fit a set and you have a tough front end. With 80's and a rear track rod you need the High pinion front diff so some thing had to be done to replace the Hilux size diff . I started building up the custom GQ/80 front diffs over 8 years ago and have done heaps with excellent results. Ive built up a few with Longs C/V's and axles recently and havn't heard of a break yet. Im not implying there tougher than a Dana 60 but the brakes are far better bearings and hubs are on par but the enclosed knuckle is far better for deep mud etc ( less maint but messy ). I have broken C/V's when abused but everthing has a limit when there a B/Block under the bonnet wanting to keep the 38's turning. I will be investing in some Longs C/V's and axles soon when my supply of new Jap made C/V's is used up so im keen to find how hard i will be able to push it with some Longs.
