Haven't had a proper look at how diff is mounted, but looks like drivers side axle seal is leaking - is this something that can be done with it in the car? Any Special service tools needed?

Don't mind if I have to pull it out as I wouldn't mind checking out the diff.

Thanks

If it's the side shaft oil seals can be done in place.

Remove the side shaft bolts that connect the inner side shaft to the outer CV, negotiate (hammer) the inner side shaft out and replace the seal.

As in I cant wait till my diff goes not that the seal is a common fault as far as Im aware! From memory you did a spectacular job at ripping your TRD LSD apart Nick!!! Dam weak F series!

Just use the right grade oil and do regular changes and you should be fine. F series diffs are notoriously weak but our Altezza ones seem to be holding out well but that doesn't mean they haven't failed! Even the TRD ones...

You can get Tomei, Kazz, Truetrack, cusco centers that work quite well too.

I was going to throw some SAF-XA in at same time that I do the seals so hopefully that keeps it happy.

I've got my suspicions that it may already have a 1.5way or something in it based on some 'testing' =p .. wouldn't mind pulling it out anyway to have a quick look and do the seals on bench.

I know mine def stock but the F series LSD is naturally aggressive during deceleration which is the only way to see if you have a 1.5 or two way (as in you should hear one wheel lock up under high rpm down shifts with slight brakes not two or in the case of a 1.5 way you will need to jam the brakes under high rpm down shift to get one to lock and send you into a spin or a wall lol). Acceleration off the line it will spin one then quickly balance the torque, I can hold both wheels locked in a power slide for some time too so its quite fun stock but just week. Its the same LSD as found in the Chaser, cressidas. The Supras and soarers got the G series sad.gif

Interesting.. pretty hard to tell, apart from the occasional chatter I'm used to from driving nissans with aftermarket lsd's.

Given the history of my car, that it originally had swaybars, coilovers and bracing everywhere when it came from Japan I wouldn't be surprised if an LSD was also thrown in.

True, such a shame that cookie dismantled half of it. Somehow I ended up with his Toms engine brace smile.gif

Then again I have every brace you could think of apart from a cabin brace or a roll cage and fender braces (the triangle braces that go in the fenders), sway bars tein suspension and im yet to invest in a decent LSD but then again I have had my Altezza on the skidpan and its quite nice (Still could use a 2 way to get a proper power slide though!)

Agreed. Got a pic of the engine brace in question?

Cabin braces (monkey bar or b pillar) are useless.. cage + fender braces are usually good though.

Diff feels good from playing around in the wet and a few sneaky slides here and there.

Mostly true, however the times I kept smashing pinioned and crowns was with the Torsen unit which I had shimmed up. Was great on pickup but cause a lot of under steer. Has a 2nd hand TRD unit which required a rebuild which I sold and just bought a new unit. Have yet to look back since then!

Using a thicker (80W-140) with the stock Torsen unit helps them lock up alot better by adding more initial preload. But always, always use a GL-5 rated LSD oil for the Torsen unit. If the oil smells burnt when you change it, it is.

Currently using a TRD 2way with TRD LSD oil and after many track days and gymkhana days I've yet to fault it smile.gif

PS, it's silent and not as skippy as a mates Cusco unit lol!

Agreed most the time when the diff breaks its the C&P and not the center.

Either Torque or Axel tramp will cause the C&P to break.

I haven't looked back on the TRD unit either smile.gif

PS. I broke a C&P with running a 2way cusco and it too skipped around every corner.

I think for our cars fender bracing might be a good investment since they are getting old. Also we do put our cars through a bit of abuse.
