New member and 1st post and I need some advice please,
Car details ..wrx sti prodrive type UK on a 53 plate....full Subaru history ...engine re-build with new clutch and timing belt at 125K from Subaru.mileage is now 142K.
Last couple of months I have noticed that when the car is hot (driving for at least 20 mins) I am getting a knocking/clunking noise from front when turning at low speeds ie parking spaces either going forward or back .Thought it might be CV problem but from reading on here I am convinced it is the centre diff.
Been quoted £2700 from one Subaru garage for the part only!!!
Quoted by another £1600 to supply and fit?? £600 for parts and £1000 labour as gearbox needs to come out apparently?
Do these figures sound reasonable?
Just had gearbox and both diff oil changed by my mechanic and although it seems a bit better , I am sure I need a new centre diff.
I just wanted a bit of expertise on whether I should go ahead with the garage for £1600?
Live in London area so not many Subaru garages about.
Any help would be much appreciated .
Many thanks ....Tony.

 

Second quotes not too bad but your in the wrong end of the country silly prices down there. About six hours work and the price of a diff out of a breakers. That includes stripping the box which isn't a big job its only the tail end that needs to come off.

 

Thanks for the quick response mate ....I know what you mean about trying to find parts in London. Will keep my fingers crossed for a solution because I love the car and even though I aint a millionaire I still want to try and resolve it without paying a fortune!!! My pride and joy....gutted!!!

 

Have a read of this

I’m pretty certain you have the same problem I had.

Suspension strut top mount?

 

Just to add, mine never made a sound when the car was cold, when it was warm it was a different story.

The non viscous diff is a sealed unit with a special silicone to aid lubrication/internal movement.
Once that silicone starts to break down you need to replace the diff.

They can implode and make a real mess of your box if left too long.

Centre diff failure on the non dccd 6 speed is getting pretty common now.
