forester rear diff

[Mark hammill]

hi all i'm back i think my new to me forester needs a rear diff is their a difference with manual and auto gearboxes so i need a specific diff ?????

[Mr B]

manual/auto differ, best way is take numbers off the diff casing so can source right diff off other model variants  and pay realistic prices .

before commit to the job be sure it is a diff issue, rear wheel bearings and uneven tyres are common faults diff gets blamed for .

[Mark hammill]

cheers tyres are newish by the looks of it i'm going to check wheel bearings and brakes i became suspicious of the diff when i opened the filler bolt and half a litre of oil came out on level ground

where am i looking for number on the diff ?

thank for your reply 

[Mark hammill]

its noisy and can feel resistance/grinding when turning tight circles at slow speeds 

[Mark hammill]

so have looked at the differential the only markings i can see are x261 

 

[Mark hammill]

does anyone know if this one will work on my forester xt 2.0 auto 54 plate 

eBay item number 261489040954 Subaru Impreza turbo Auto Rear Diff 522B Perfect Order?????

transmission code for my car is TZ1B5LNYAA

[Mr B]

You most likely want a 4.111 ratio viscous diff .
You best first seeing what can find based on salvage 04/05 2.0xt auto

try a few specialist subaru breakers or keep looking on eBay etc .

option 2 is getting yours looked at and rebuilt if cost viable  .

 

[Mark hammill]

thanks mr B for the info will keep my eyes peeled 

[Mark hammill]

so am i correct in thinking any viscous lsd diff with a 4.111 ratio will do it ????

[Mr B]

Most likely but I know from ordering dealer parts lot of the actual viscous diff assemblies are listed forester models only .
For less risk of hassle I'd try find a forester xt auto first or take advice from specialist breaker .If you send few emails or make few calls you'kk get idea on prices and maybe options then wait on eBay if trying find one cheap.
I'll send you details of breaker we used for few mail order parts to try your luck as had very clean parts at reasonable prices, they large breakers but not subaru specialists but that why prices more reasonable :-)

 

[Mark hammill]

Cheers MR B someone on another forum has supplied an extensive database of when and where the parts were used on which subarus,And it seems the manual is the same as the auto according to the information 

[Mr B]

that would be good.

More than likely any viscous 4.111 will do but they have a lot small design changes but still likely all bolt on and work .

I know from buying diff parts an 05 had different viscous p/n to 02<>04
