OK guys I am on the verge of purchasing a diff form a fellow club member and just need to knwo exactly which part i need to swap out. Its a s4 n/a lsd. I have a s4 n/a automatic non lsd. Exactly which parts of the diff need to be switched. Just asking to save money on shipping. I saw an article about swapping a miata lsd into a fc. he only switched the guts. is this hard? What would be the easier,cheaper,safer way to go?

just throw the whole thing in, dont bother with swapping all the internal gears and stuff, its a bitch, i did it with my 86 n/a and wont do it again.

It will be heavier, but at least it'll just be a bolt-on installation. 2 bolts to the subframe, 2 nuts holding it to the car, 4 bolts for the drive shaft and 4 for each half shaft.

hahaha you think that's it? have fun!

ok, first, jack up the rear of the car. pull the wheels.

pull off the brake calipers.

pull the sway links

pull the driveshaft bolts.

drop the catback.

unbolt the lower bolt on each strut.

unbolt the traction bar to the driver's side of the diff.

with a jack under the diff/subframe, unbolt the 2 diff mounts, the 2 subframe mounts, and the 2 14mm safety bolts next to the subframe mounts.

helps to have 2 other people.
