It's not the LSD that needs adjusting, it's the diff settings with the preload and backlash that needs to be set correctly.

Oh ok. Nope it won't void the warranty. I actually bought the LSD before I bought the gearbox planing to get bits together to do one later this year. the box just happened to go sooner than I was hoping.

It will get fit sometime but I really don't know when

Really? RIPPED!!! I'm using an LSD oil in my gearbox at the moment - it shifts better with this stuff, looks like oil but certainly didn't cost $100 for 5L!!

I did previously have Castrol stuff in and it was sh1t. I then swapped to Penrite LSD (good sh1t anyway) which was ~$55 a bottle (2.5l to a bottle) and this made it shift much better. I didn't put the Red Line Light Weight stuff in as thats around $200 for 5L. I will again be putting the Penrite stuff in this week when the box goes in. Hopefully the box will be here tomorrow otherwise Tuesday

Really??? I have the LSD sitting in the boot of the car. Currently no plan of when it will be going in...

Want me to ask my mate what he'd charge to split the box & put it in for you before you put the new box in or oil in it so there is no cleaning up...He did mine and just put one in my son's RA STI box....That's provided it's an OBX though he can do both.

At the end of the day to stop that tyre noise will require new tyres. The front to back trick is just a diagnostic test, but it might quiet it down enough to put up with it. Its suprising how loud they can be, i drove a 350z at work that sounded like it had a helicopter under each wheel arch.

Well, I only purchased these tyres in October last year. I haven't rotated them yet. I miss my Yoko's from years back, so quiet, soft compound, it was on a 2wd, so they lasted quite a while.

I went to put in more oil but I can't seem to get a proper reading on the dipstick, I clean the dipstick and re-insert it and the oil seems to cover the stick above the hi notch, the transmission is also cold, so I guess that it's full?!?

Yeah that would be great!

I just spoke to a wrecker, he thinks that the worst case scenario cost wise would be $2200, he cracked it when I mentioned a WRX replacement box saying that it's double the cost and not geared right for N/A Libs. I'm going to drive to some mechanics in the next couple of days.

It takes very little oil to overfill the box, probably 250mil from just reading to the correct height on the stick, we filled my son's gearbox last night and it was 50mil at a time to get it right.

I'll try to remember to give him a ring tonight Taz

Got the message, thanks.

Does overfilling the gearbox hurt it? I know you should never over fill an engine with oil..

Might spit your dip stick out?? we put just under 3.5L in it but yours may take a little less with the extra hi/lo gears in it.

Nulon G70 additive for manual gearboxes only, has some benefts, $25 at many good car parts joints. Some people drive a noise until it gets worse- making it easier to identify, or drive until it lets them down, or trade it in and not even have it test driven by the dealer

, then the dealers wholesaler gets it, finds noise and reaches for a little G70

There is a few L Series out there I wish someone would fix before they die a noisy death

Well I went to three mechanics today.

Mechanic 1.
I took the car for a drive, he chucked it on the hoist and listened to all four corners and the diffs and transmission with a stethoscope. He said that the front left wheel bearing is slightly noisy and the right is more noisy but the rear diff sounds fine and around the transmission area sounds normal, guy in the car was in the 3rd and 4th gear. I was told that if the bearings are not the issue then I don't have to pay or can reach an agreement for half payment. They also have a courtesy car. Total cost for full rebuild $4000 or can go second hand for a lot less. $350 front wheel bearings. Repair time is around 5 working days.

Mechanic 2.
I took the car for a drive, I also drove in reverse with the car fully locked to turn left, he said that it could be the Viscous Coupler and he said that it could of strained the centre diff. Cost could be from $1500 to $2000, he has to send the box away to reco. I doubt that they have a courtesy car and repair time is around a week. He also said that the wheel bearings IS NOT the issue.

Mechanic 3.
He took the car for a ride, said that it sounds like the rear bearings in the box, luckily that he can partially remove the box but worst case scenario is 3 x $800, so mininum cost would be $800 or up to $2400 but he doubts that it's all three, the rear bearings he can do in a day, he said that it could also be the mains gears one or two and that could take a little longer as this has to be ordered cost $800 and the Viscous Coupler is around $800. He has a courtesy car but he is also the closest. He also said that the wheel bearings IS NOT the issue.

Wow, I can't believe I got no reply.
