140????????
Are you mad?
Thats WAY too thick for a lambo mate!
Thats what you use in planetary gears on a truck diff, hah hah hah.
Ok I'll let you 2 guys "duke it out" on the 90 or 140 thing but XSNRGY where did you buy your oil from (I'm assuming in Australia)?

Thanks for all of this!

Umm......are you not reading all the posts.
I'm in NZ and got it from BNT Automotive - I thought it was an Australian company?
Anyhow, just google the oil and find your nearest supplier.

So I got up this morning to take my car to Lamborghini Sydney and it creaked as usual as I turned out of my driveway. 2 hours later with the mechanic in the car, the car SIMPLY DID NOT DO IT!!!! The mechanic said it was in the differential but said as there was no noise everything is/was fine,........ so I drove 2 hours home. BUT as I turned into the driveway THE BLOODY THING DID IT AGAIN!!

I'm buggered if I know what to do!!! Yours discouragingly ED

Ok, OK, shee you Kiwis are pushy! (too bad you can't play cricket - but I digress).
I'll get your recommended oil and let you know how I go. Your suggestion can't hurt and I think you may be right.
As for Covid, if we had your PM we'd be over it but then again, we could've had Trump and REALLY be in trouble with Covid!

Hi,

I might be mad as I am a lambo owner :)

I am running Quaife billet LSD which is gear driven.

Have had no problems with running the Amsoil 75-140 severe gear oil in 80,000 kms.

Much better than banana skins in the diff :)

cheers,
john

Hi Ed,
on a serious note, it may be the LSD clutch plates- locking and then unlocking at random with corresponding clunk- the mechanic should have checked for brown colouration in the oil from worn LSD clutch plates, but sometimes difficult to see, not metallic. If it is the LSD, then unfortunately a gearbox out and rebuild. Not cheap. If you have to do this you may as well look at new clutch, throw out bearing and position sensor as well as a new OEM LSD with 'upgraded' harder wearing clutch plate linings or even a Quaife billet LSD.

The experts on the forum on the operations of the Gallardo OEM LSD may be able to explain more clearly how you can get a clunk from the LSD as it unlocks.

I believe that Underground racing had a few surplus Gallardo ones for sale.

Here is a brief explanation on the difference between the two styles of diff and why the oem LSD might clunk as it unlocks if worn or pre-load has altered and the Quaife does not.

"The Lamborghini ATB differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, it automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks."

It might be a CV joint, but these don't seem to fail that often. Again the mechanic should be able to check this. Repair is relatively inexpensive.

Unfortunately as these are mechanical items, no codes will be thrown on a Lara/ Rosstech vcds scan.

If your lambo mechanic cannot provide you with satisfactory diagnosis, take the car to a transmission specialist for a second opinion. Of course the intermittent nature of the clunk is really frustrating as you have opined.

just my two cents worth.

cheers,
john

Yea, we must all be mad as hatters.
AND on that note, why on earth would you recommend your truck diff oil that you use in your super duper flash billet diff to a guy who has a factory Lambo diff? :oops: :eek::oops:o_O:rolleyes:(n):oops:
The poor bugger is already confused as it is!

Hi Xsnrgy,

The gearbox/diff in my oem 2009 LP560 was a little bit noisy to me, so I changed it to the Amsoil severe gear oil 75w-140 and transformative! Noise went away. Now maybe the Amsoil 'thicker oil' is dulling the noise that was coming with standard oem lambo gearbox/diff oil as there is something not quite right with my oem gearbox/diff, but the car only has 15,000 miles on it.

I know you are tongue in cheek on calling Amsoil 'tractor oil', :) but Amsoil is recognised in the US as 'a leader' in synthetic oils' and one of the better synthetic performance oils for high performance 'applications'. Well that's what they say anyway.

This comparison of the Amsoil synthetic severe gear oil 75w-90 against other gear oils is interesting:


And Amsoil state that their severe gear oil 75w-110 is a great replacement for oem 75w-90.

But obviously, you cannot go wrong using the oem Lamborghini Gallardo recommended engine and gearbox/diff oils, and definitely during the warranty period!

Horses for courses of course.

cheers,
john

ps I am not an agent for Amsoil :)

Why do you keep twisting my words, I said TRUCK oil not TRACTOR oil 😋
And whats wrong with tractor oil anyway?
Ferruccio stuck it in his Lambo tractors 🤣
And I dont recommend factory Lambo gearbox oil for the early cars to anyone, period, not after wasting hundreds of dollars on it to make the noise worse in my car.
Fuchs oil is German and remember, they have the "go as fast as you want" Autobarn to play on!
If you like something that has the consistency of thick treacle which would have the ability to lubricate even a seized bearing ( LOL ) then thats what you should do and if it works for you all the better.
If Blossom has a stuffed diff / box then he might as well try your option but that seems like the ambulance at the top of the hill to me.

I use Amsoil 75W90 (SVG) gear lube along with their Slip Lock (ADATB) limited slip differential additive.

I recently had a strange clicking / whining noise coming from the front passenger footwell which turned out to be a wheel bearing. In order to isolate the issue I put the car on jack stands and ran it with wheels off the ground. Moving a cell phone camera under the car allowed isolating the noise to a specific area. While this is a bit unorthodox it may be an option if the sound you have is persistent when there is minimal load on the drive train.

Thank you, but is your car close to a 2004 Gallardo Egear?
