Which GU or MQ axles under a series Landrover....?

[SeriousIIa]

Hi,

I'm running 36 Silverstones. So keep breaking the upgraded rover stuff in my series axles.

Now am looking for a different brand of relatively cheap axles. To prevent breakage and go to a wider WMS right away series are 138 cm.

Nissan Patrol (GR) (*they are called like this in Europe) are very common and cheap in Holland. did some searching but couldn't get with the right answers.

Looking for a set of axles.

- Diff on right side front and rear
- at least 4.7 ratio
- strong enough to take 36's
- WMS 138 cm or more

Any suggestions which types and models Nissans I should look for.

Thanx for the input!

Cheers Bowy

Gday Bowy,

I've looked at your website a few times. You build some very nice trucks!

Funny you should talk axles, at the moment I'm removing the Hilux axles and replacing them with Landcruiser 60 series axles. These are wider and have big diffs in them for strength and the diffs are all offset to the RHS which suits Rover. The problem is that they only come in 4.1 ratio. Thats good though as I've got the V8 and LT95 from a stage 3 in it.

I don't know a lot about the Nissan Patrol diffs, and I didn't think they came in ratios up to 4.7, but they are a very strong setup and very wide.

You can put Toyota Hilux (minitruck) axles underneath, which come with 4.88 gears. These axles are a similar width to the Series axles, except they are designed to run more offset on the rims with Landcruiser wheels. This setup ends up being about 8" wider overall I think it is. My 31x10.5 tyres on 15x8" Landcruiser rims stick out about 50mm (2") outside of the guards. This is a strong setup.

Cheers
Simon

MQ/MK 2.8 petrol we mainly got 4.625:1 diff ratios and would be suitable.

Later GQ/GU have a different offset at the rear whcih might cause you issues.

Also the gearsets for the GQ and Gu are normally aroung 3.9:1 or 4.1:1.... gearsets for 4.625:1 are available but even here in Australia are about twice the price of a set of GQ diffs.


Given that you specified you're on a budget, and your intended application the MQ diffs (circa 1980 -1987 for us) sound like the go for you.

Do you know if they are the same, short and long wheelbase? (the ratio) and with different engines. ?

Do you have a picture of MQ/MK? series so I can compare it to our "European" patrol names

Thanx for the input!

Hi Simon,

Thanx for the compliments!

I would also be happy with a set of Hilux axles. But they cost about 1500 to 2000 euro's and a set of Patrol axles only 500 to 600 euro.... so easy choice considering the budget.

Is it any problem having the diff in the middle instead of on the right side? (will the prop notice this...?)

I know that the GR is the other (European) name for the GQ. if that is any help.

GQ




MK/MQ (its a MK)

Hi,

You have possibility to find in Europe axles with ratio 4.875. These heavy duty axles was mounted on the Patrol 160 hardtop with petrol engine 2.4, manufactured in Iran. I've payed for complete front and rear axles 400 USD (in Russia).

[Hobbz]

The 2.8TD GQ(GR) runs 4.6xx gearing ...
The front diff. is offset to the right and the rear diff. is mounted in the middel ....
The GQ has a REALLY strong front axle, and the newer GU is even stronger and a little wider ...
Hope it helps ....

Nicolay this 160 hardtop is this a MY or a GQ? Sounds like a very favourable ratio. And are the this the stronger axles or the weaker ones? Which sides are the diffs on?

[Beastmavster]

There should be info in the bible about the available gear ratios in the MQ, GQ and GU.

Over hear GQ diffs with lower ratios (higher numeric ratios) do cost a lot more than the same ratios in a MQ diff.

MQ's also had a 4.8 ratio for the utes.


Any of the Nissan diffs will be way way stronger than an equivalent toyota one, and also will be likely to be much wider. Toyota have normally widened wheelbase by running negative offset rims, where Nissan normally had positive offset or 0 offset.


Overall though, without knowing exact model specs you got there we can't give you 100% exact advice, only what we'd do here in the same circumstances.

I believe there are a couple of rover boys on this forum running Nissan diffs so maybe you'll be able to find a thread in there about their experience with a good search.

This is MK Patrol with right side diffs. The front axle C200 type is a standard, but rear half-floating H233B is a heavy duty. It means that diametre of a spline part of the axle shaft is 32 mm instead standard 30 mm. Also all Iran MK's were appointed by LSD.

Hmmm, I'm really not sure to be honest. The Hiluxs are coming out before they've really ever been run. The Nissans rear seem to be ok in the Rangie conversions though.

[bru21]

cheap and strong would be 60 series through to 75series axles with longfields cv's. a set inc cv's would be close to 1k here.

gu's are not offset but a chop and 2 new axles could fix that - $400 for each axle. you can buy 4.8 in gq/gu/gr but they are weakish in the pinion
4.625's came out of the gu 99 mod etc 2.8 diesel

cheers bru

[Screwy]

out of MQ and GU...

MQ are much much cheaper and easier to get parts but also weaker and not as wide......

GU are expensive as but stronger...

its a compromise...

as bru said, u can get longfields for toyota crap and not for nissan stuff at the moment so maybe look at 60 series diffs?

Today I've just finished installing LC60 front diff as sprung over and connecting the steering. A very easy conversion so far, and the spring perches on the front line up with the LandRover springs. Pinion angle is also flat.

I'm coiling the rear, but the rear looks like a set of perches only to suit the LandRover chassis.

ITs also looking like the pinion flanges will need to be changed over to Hilux so they can be machined to suit the Rover prop shafts.

The LC60 diff pumpkins are also offset, and this setup is strong with a set of Haultech CV's. They'll play with the 36's, but are 4.1's, not 4.7's.

Back when I owned a 1989 pathfinder i was dreaming of a SAS and the USA websites have some good information as Patrol are not available over there. Have alook at

There was mention somewhere about conversions being done to Toy 60 series axles to accept a GQ/GU 3rd member. This way, you get strength of Nissan, with ofset of Toyota. Not sure what is done about axle shafts with this conversion though.

Screwy, Are the MQ axles WMS wider then 138 cm then it's enough. If they are strong enough for Sivlerstones 280x85 then it's enough for me. Price is a concern. Oh btw I run a 4cilinder petrol engine with less then 100 Hp. So no big power figures to really test the axles..

More important to me are the ratio's is the MQ available in 4.7 or higher?

Else I have to look for GU .......

Thanx for all the input so far guys!

Cheers Bowy

MQ came in 4.625 (most of - petrol 2.8) 4.875 (utes - stronger diff) and 4.333 in Australia to my knowledge.

MQ came out in 4.625 is the most common, u can get them in 4.8 but very rare......

mq diffs measure 1340mm from the back of the drum to the back of the drum so id say would be farely close to your WMS measurement.
