back lash is how the teeth on the crown wheel and pinion come into mesh. Ummm sorry I'm having a mental blank but im pretty sure to adjust your backlash you move the crown wheel assembly in or out of mesh with the pinion

Not sure how its done on skyline diffs but

an oil change will do nothing if this is the problem

ok the back lash thing, sounds like it could be it, the front diff is a 2-way os-giken lsd so if it is backlash ( crown and pinion not meshing correctly ) does anyone know a fix for this.....

ps.. its not the normal 2-way lsd noise, I know what that is...

cheers

Ah crap i didnt know we were talking 4WD lol. But yeah it could be the way the diff was installed, maybe incorrect backlash. probably the easiest way to see is to park the car (On a hoist or pit if possible), get under it with the brakes on and try to turn the drive shafts, Then lift the front two wheels up and with the car in gear try and turn either wheel and see if there is movement in the diff yoke (or however the transfer box is connected to the front diff) and do the same with the back wheels

That might give you some clues as to where the problem is. If its your front diff backlash then with your front wheels off the ground and the car in gear you should hear/see/feel any play in the system

...

with the front wheels off the ground, you can only turn them about 50mm or so either way, so just the slack in the diffs and cv's etc I assume... does that sound normal.. maybe I should compare that with the back ??

yeah i guess hey? Can you take it to a diff/drivetrain specialist. They might be able to do a good test of everything for 20 buks or something ;)

funny I rung 4 diff workshops here in perth and not one of them has ever seen of heard of an OS-Giken front 2-way LSD, but yeah might get one of them to look at it anyway

cheers

What do you mean by 50mm?

Rotate the front tailshaft (not driveshaft) back and forth and see how much play it has. It is directly connected to the pinion so you will know if there is a backlash issue there.

Then turn the wheels back and forth to check how much play is in your spider/axle gears, as this can cause clunking too.

yeah meant with front off the ground the front wheels only turn bout 50mm back and forth, so i assume thats play in the "spider/axle gears"

I haven't tried the front tail shaft for play, but when i put gaerbox back in recently i didn't notice much play in that...

think i'll just have to take it in somewhere and get it looked at

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
