Outer Limits 4x4 Board

Thanks for the info Dave. Im no longer in Sydney moved down south a while ago and havent updated yet. It has to be the bearings. The diff was just pulled out and new bearings in that, the tailshaft has had new unis and rebalanced twice and the pinion angle is spot on, the gearbox was rebuilt just ...

Cheers Maverick. I am going to hope its the bearings and just change them. Any idea on cost from a bearing comany off the top of your head and any brands to get or steer clear of? Do worn bearings make this rumbling sound? It is there between 70ks and say 100ks worst at 90ks and regardless of ...

Thanks for the reply AJ. I know they are known to be bulletproof but doesnt mean they cant go. They have no play in them and arent noisy at all untill about 70kmh (if that is what the noise is). I had a look on ebay and they are like $150 a side plus then I will need to get them pressed out. Just ...

I have been chasing a noise in the rear of my wagon now for a while and gave up for a bit but it is getting louder. The noise is like a rumble in a grrr grrr grrr grrr sort of pattern. It is heard most at 90ks and gets softer at 100ks. Its enough to send me nuts. Today I pulled the rear axles out in ...

Does anyone know the legalities of replacing a RD28 with a RB25DET motor in NSW????? I know it has been done in VIC, WA and SA but am unsure of the rules in NSW. I am planning on contacting an engineer (can anyone suggest one) but thought someone might know if it is possible without too many mods ...

OK sounds too hard basket to me. I think Ill just get the GU one to start with.

Thanks Fellas

Is it possible to fit a GQ gearbox from a td42 into a GU? I know that the shifters are in a different position, but are they the same box apart from that and can the shifters be changed or something to make the box fit properly?

I am guessing someone has done a holden injected 5 litre into a a GU wagon before?
What sort of fuel economy are you guys getting out of them?
Also would it be better to go manual or auto?

Cheers in advance

The 2.8 diesel and 3.0 petrol share the same "small" alloy box which is a skyline box with a transfer case added.

I had a 3" lift in my GU and the drivers side rear sat 25mm lower than the rest. I swapped coils and mucked around, got a replacement set under warranty and ended up fitting a spacer to fix it, untill I saved some more cash and fitted megalift coils and I have never been happier. Better flex, holds ...

If you don't want flexy coils get the usual linear Dobinsons coils. Dobinsons do have a better manufacturing proces for coils. Shane Someone was telling me that dobinsons werent that good and most of the time you ended up with a 4b with different heights at all four corners requiring coil spacers ...

Im with ozy the lower arms are adjusted out too long. When adjusted out longer than standard they will rotate the diff round untill a certain point and then every mm wound out it just pushes the diff back. The uppers should be used to correct pinion angle.

make sure you loctite the crankshaft bolt in place as they come loose. This happened to me about a month ago and stuffed the key and balancer. Got away with minimal damage to the crank luckily. Could have been a lot worse. The thing hadnt been touched in 85,000 kms when the timing belt was done so ...

$2300 new? Where from?

I did last weekend. The main crank bolt came loose and the balancer moved forward and snapped off the key. New balancer, key, fan belts, timing belt kit were fitted and seems OK for now. $825 was the cost of the parts. I used loctite on the bolt when I reinstalled it. It did minimal damage to the ...

I have used West End aswell and couldnt be happier. I too have a GU 2.8 and I had it chipped there. They were very profesional and the workshop you could eat off the floor. I am getting about 950kms for both tanks with 33s aswell. I already had the exhaust and I got the chip installed there. I now ...

How much are these arms?

Which bolt do you take out? Front or back, left side or right side, or doesnt it matter? Is it a bitch to get it back in again?

I have spoken to a couple of diff and gearbox specialists and they all are saying not the diff or gearbox, but the tailshaft. Maybe the slip joint. One thing that has become apparent is the amount my slip joint is pulled out. It is pulled out 60mm, and after looking under other GUs they are only ...

I have set the pinion angle using an angle meter and it is spot on. I have snake adjustable arms, with the x-flex bushes they come with. Has anyone had any problems with these? I had vibrations and with the arms now set it has all gone except for this bloody noise

Yes it is the smaller gearbox. And yes I think this has somthing to do with the lift. I was getting a vibration, and have fitted adjustable upper and lower trailing arms and have corrected the pinion angle. Under load is now perfect, as is coasting, but when just feathering throttle I get this ...

I thought it might have something to do with 5th gear but it does the same noise in 4th aswell but you need to be going fast like over 100 kmh.

I went down the coast yesterday and noticed at highway speeds a noise that I am quite concerned about. At 120 full load no noise, no throttle no noise either, but as I just touch the throttle or just as my foot is about to come off the pedal it is making a grinding rumble sound felt and heard ...

Yes I saw that trucks, but it works by telling you the angle of how far the arm is spread apart, not the anglwe it is sitting on. I got one from Bunnings today, and it was in the tool section where the power drills and stuff are, right next to the spirit levels. Cost $40 and now I have checked it ...

Thanks Dave.

Thats what Im after guys.
Thanks.
Which section in bunnings did you find it?
And how much was it?
I always like to cheat when I can my maths isnt that good!

As the topis says who would have an angle meter?????????
I have read some posts on here about setting up pinion angles, and some have mentioned using and angle meter to get the angles correct, but I cant seem to find anyone who knows what one is let alone have one.
Does anyone know?

But I shouldnt need a longer slip joint on a GU with only 4 " of lift??? Should I??????????????? And at $550 to buy the slip joint, I may as well get the shaft lengthened for $300. I still think it is the angles. It bugs me though that I look at these other lifted GUs and the pinion is up in the air ...

Yesah I figured the lowers needed to be lengthened more to acheive the same thing?
I am going to borrow an angle meter to make sure the angles are right first.
What do you mean by all wrong?
