Dirt pigs I fitted 4 inch lift with king springs and rancho 9000s myself at home the lift is easy but the vehicle a GQ lwb was all over the road had eccentric bushes fitted and it was a different car stable as found the bushes wore out very quickly when used for the purpose the car was built for built my own 5 link front end can adjust the amount of castor and heaps more travel if money is a problem go the corection plates far better than constantly replaceing bushes every 6 or so months
What was the Repsol fluid that you put in your rear diff ?

doesn't the 80/90 gearoil make your rear lsd shudder when turning at the lights etc, it should have LS 140 oil.

Nope, works fine. Had it in for a couple of months now.

mine did it really bad and when i rang the mechs up [it was in for a warrenty repair] and asked them, they had put in LS 85/90 so they changed it for the correct stuff and it fixed it.

I'll have more of a chat with the mechanic about it, but he has been running the Cartago in GQ's for quite a while. Was the fluid you were using Repsol Cartago? I am told it is a high end diff fluid, not a normal off-the shelf fluid.

they put in castrol 85/140 LS oil.
I thought it quite strange that they had never had the oil in stock and it was a large ford dealership and they should have known that the mavricks [patrols] took 140 oil in the rear diff.
Makes you wonder how many new mavricks they serviced with the wrong oil
No wonder i do my own servicing

Now, the only thing that I am a little unsure about is how do I know what sort of castor correction I need. I know if the steering is vauge after the install it needs correction, but how do I know how much is needed... is the old 1 degree for every inch over stock a good rule of thumb?
If that is the case, I probably need 3 degrees... but I don't really want to go eccentric bushes becasue they will bind more than the stock concentric bushes. That leaves plates.
Do they come in 3 deg?
Does it matter if I go 5deg if I only need 3 deg?
What are the side-effects of a few degrees too much castor?
The side-effects of to much caster is the steering becomes heavier (noticable at slow speed) because the more angle you have on the king pin (caster) it lifts the axle up when you steer to full lock the extra effort applied to the steering wheel is lifting the weight of the front of the vehicle, this becomes more noticable with big offset wheels. If your running standard offset wheels you wouldn't have any problems up to 5 deg caster, bonus here is good high speed stability.
Hope i answered the question you asked!

I'd say leave it the way it is. out of the factory nissans have 4 degrees positive castor. the specs are 2 degrees plus or minus 2. take the 4 you've got and the 3 that'l come off you're left with one degree, well within spec and alot closer than stock..
I got done with mine.. an expert put 7 degree plates in mine with 6 inch lift because "i really needed it" according to him. i've had no end of trouble since i'm just about to chuck the plates away and go back to whatever i get without em (apparently i now have 7 deg pos) 0 is within spec, 7 is plain dangerous..
But thats just my opinion.

I can't believe anyone would contemplate taking out their coils and fitting leaf springs.
The next thing you know we will all be fitting side valve V8s because they worked for Granddaddy when he was a boy.
Or if we want to go really slow we can fit the optimum boat anchor ,

God this thread certainly went off topic by some who should know better.
5 degree plates dont give 7 degrees of caster, they move axle 5 degrees, same with bushes etc.
Drop brackets at rear of lower control arms are also a good option and improve driveability.
