Isf diff

[Isf marc]

Has anyone got a isf/Rcf diff for sale ? Or now where I can get on rebuilt ??

Is your standard diff blown? 

For rebuilds I would have thought anyone who does gearboxes/diffs should be able to rebuild, depending on whats actually failed. 

OE diff's aren't common around here. Standard open diffs do come up in Japan regularly though for not very much money, usually just the diff with no housing, have a look on Croooober or maybe one of the importers who can buy through Up garage.

If your housing and ring gear are OK, you could always upgrade to an OS Giken...

What are your symptoms? Just out of interest how often did you change your diff oil and kind of use did the diff go through?

I too would recommend a upgrade the cusco diff a little better priced os giken.

There’s a clonk when I take my foot of the gas then like a click/rattling sound my local Toyota Lexus specialist test drove it and said the diff is shot when they tested is in reverse the wheels nearly locked up now it’s sound like sh## these one on Ebey out of a RCF LSD  £2700 seems a lot but I’m no expert

I thought £2700 was expensive considering I could get an RCF gearbox and torque converter together for £1700.

@Isf marc could be a golden opportunity to look into other diffs. Quite a few fit our cars, a quick search on Google and looking at the American forum they've swapped in IS350, GS450h diffs with a higher ratio, aiming towards better acceleration.

If you want standard, and if you can find one, the diffs used on the LS460 F Sport are the same as ours. See below from the American forum

New diff time for sure. 

As mentioned above maybe worth looking into a LS460 etc im sure they will be breaker who'll sell it you for a few hundred.
