If so is this possible on the driveway?
I've been told it's relatively simple to do, taking around 2 hours

Anybody got any tips? Do the rear driveshafts "pop" out with a sharp blow via hammer/blunt chisle or are they on circlips?

It's a MY97 UK turbo 4 door

Thanks in advance

 

yea, you can do it on the driveway.. driveshafts are on clips iirc.. but should justpull out.. they may also have a roll pin that needs knocking out..

it may take you a little longer, more like 3 - 4 hours..

Beware the diff is heavy and can hit you in the face!

also use thread lock when putting the bolts to the prop back in.

Thanks David!

 

Remove oil
remove diff/prop gaurd
remove prop bolts
undo front 4 diff support bolts first
support diff
undo two rear diff bolts
pull diff out of mounting rubbers
turn diff 35degrees
pop out first shaft, crow bar pops them out
pop out 2nd shaft.

put first shaft in new diff, make sure it pops back in all the way then turn diff to get other one in at an angle.

This will save you splitting the hubs etc to get the shafts out.

much appreciated.

Thanks for the info guys

 

Wish I had thought of twisting the diff to get the shafts out!
I split the hubs by withdrawing the l o n g bolts from the lower arms.

Job is a real meccano task, just bulky and awkward. A thousand time better than doing a gearbox

Good luck,

911

 

Another tip for you as i am feeling generous

Use one of the front diff retaining nuts and thread it onto one of the rear diff mounting bolts. Lock this nut up against the original nut and withdraw the bolt from the diff itself.
*will make sense when you do it*

This makes life much much easier as you wont have to hook the diff out.

you kinda figure out how to get shafts out once you drop it down under the car

 

Lol, first one i did... i took the rear bolts out and the diff swung down and broke the floor

Rob

 

How can something so small weigh so much? But it sure is heavy....
I have to really slam the driveshafts back into the diff to get that small clip to snap into place, and having the hub bolt out gives me a good 50mm 'swing' at it.
The worst bit is the steel frame that comes off the diff to the floorpan, handbrake cables off in my case to allow the lot to drop.

Everything is hard work on a Subaru compared to an early 911.........

911.

 

Handbrake cables arent in my way on mine..

Lol at rob..

It ways so much as the case is like 1 cm thick!

 

It weighs roughly 52lbs if I recall correctly.

 

Thanks for everybody's input and help on this. All went smoothly, took around 4 1/2 hours. Except then found rear diff wasnt the problem!

It seems a rear wheelbearing, which was the original diagnosis, and was changed, is still faulty so my blood is boiling at the moment as the garage tyhen suggested the diff.

 

Might be worth checking that the hub is ok, especially if the new bearing is also noisy.
