forester99' - viscous coupling ID


Recommended Posts

Oh well, my girlfriend's otherwise perfect 99' forester started doing that strange on off rumbling noise in tight turns...

Lifted the wheels one at a time to do the torque test and yes, it grabs then releases, so 99.9% it's a viscous coupling gone.

 

now for the ID issue, according to this well put together guide :

 

https://www.alldrivesubaroo.com.au/gearbox/subaru-centre-differential/

 

i have a hard time knowing if i have the 91'-98' TY752  gerabox  that uses the early type coupling

or

or the TY754, 755, 757, 758 1999 - current gearbox that uses the newer type coupling

 

(scroll to middle of the page)

 

the opposed forces PL even shows three options to the transfer case

 

http://opposedforces.com/parts/forester/en_s10/type_1/manual_transmission/mt_transfer_and_extension/

 

Is there anyway to know from the vehicle ID what type of gearbox/coupling i need?

 

VIN JF1SF5LJ4XGxxxxx shows it's an SF5 forester from late 99,

 

any way to know for sure what coupling type should i look for?

 

tnxs in advance!

tnxs for the info guys.

so number location would be as in the pic right?

 

do i need to order other parts to do the job?

havent seen a really good description of the work but sounds like its an on-the-car job.

 

whats not clear to me is if all the transfer case needs to come off or if by just removing the end cover i can change the coupling

 

tnxs again

hi guys

well, at the end it turned out that it had the old style rebuildable coupling so i count myself lucky. Went to this super friendly small Subaru specialist that i know and it all cost around 500$ including coupling rebuild and labour,

 

Regretfully for most, he is located near Lake Como in Italy, so of help only to italian subaroids, doubt if there many (or any...) of us here, but just in case: www.autoklaus.com

 

i usually do all of my wrenching, but being on crutches following a motorcycle accident, just couldnt do it this time, would have been a bit of a stretch for me anyway....

 

tnxs again for your info
