Front Diff Removal

[9krpm]

I am going to change the front R32GTR diff with an ATS lsd tomorrow with the sump in the car. I've access to a hoist and air.

I've been told that this will be a very difficult job. Has anyone done it? Can I have some tips to speed up the process so I can see the final races at Clipsal tomorrow?

Do you guys know what oil is recommended for the ATS LSD?

Many thanks in advance.

Yeah its about a four hour job on a hoist....ive done worse jobs before....its not to bad.

the LSD did not come with the any bearing...I should have a look prior .....and the late sunday start did not help at all. The whole mission was aborted.

It looks like a fairly involved process but doable. Do you have any tips or short cuff for this?

To do it properly...yes

To do it properly...yes

So what you are saying is, all the workshops around the world are not doing it "properly" who don't pull the engine.

No...I didn't say that at all. I would like to know if it's possible to setup the preload and backlash on the car though?? It doesn't look like it to me.

I guess you could always drop the subframe and pull the sump off but that isn't really an easier option.

Yes it is possible...much easier than taking the engine out...why the new found interest in front diff's Mik?

So...you can pull the pinion and shaft out with the sump still on?

My diff decided it had enough...

Yes everything to properly set up the front diff can be done while sump still in the vehicle.

Too much power?? or was torque split being controlled by something other than ATTESSA??

I have a OS giken LSD if your interested??

Possibly. How much are you after for it? Is it complete in a housing? I assume it's 1.5 way?

[9krpm]

I've heard that the OS is impossible/unsafe to do in the car as there is some grinding involved. So dirtgarage, is there any tips for the job? How did you setup the preload?

I can see that it possible to shim up the bearing side thrust on the car, but I can't see how the pinion and shaft can come out to change the spacer.

Standard ATTESA. Went bang when it came on boost. Feels like it's broken the spider gears assembly.

[9krpm]

mik, how much torque have you got? This is the first time I hear of front diff failure.

It's got a bit I guess but I thought the front diff would last
