AU dude

i had my car up on a hoist the other week and found rear extension housing bushing was very warn and leaking a bit of fluid. i rang up ford and found out that i cant buy the bushing seperatly for au's, but for every e-series you could buy it seperatly. so i ended up buying the whole extension housing , a gasket and seal and for it, along with 12ltr of trans fluid and a service kit. so is there any problems i may run into or things i should or shouldnt do while doing this beside from actually replacing the part???

G'day mate,
do this with the rear of the car Jacked and BLocked (on car stands) as high as you can get it.
Simply remove the tail shaft, speedo drive and Crossmember (support the box with your trolley jack)

Being a 6 pot, the exhaust shouldn't be too much of an issue. The Exhaust mount and gearbox mount can be changed once you have the extension housing off.

By jacking the rear of the vehicle ONLY most of the fluid will run to the front of the box, and you will have minimal fluid loss. (last one i did, the loss did not register on the dipstick!

The secret to this job, and it is EXTREMELY important, is cleanliness. The clean the surfaces for the gasket, the less chance of a leak. And MORE importantly, autos do NOT like dirt at ALL. one speck of dust is enough to upset the valve body.

Cheers
Jas

AU dude

thanks heaps, ford manuals dont tell you anything about cleanliness.
ive got access to a hoist, and alot of tools. im changing auto fluid as it still is running factory fluid and its done over 100k, a whole 12Ltrs including converter. oh and au's dont have dip sticks, u fill them right up to the filler plug. i think this was because so that people dont pour the wrong fluid down the dip stick hole.
