Default One or two transmission jacks?

The car is on jack stands and I'm trying to remove the torque tube, A4 and differential. There is one Harbor Freight transmission jack holding up the back but should another be placed at the front of the torque tube or will one at the back work?

A floor jack can work, but is not as nice as a scissor trans jack for putting it back in. Do you have the big trans jack or the little scissor jack? The big jack on the pan with the chain or good straps can support the whole thing. But, it will not be ideal and not great for putting it back in without help at the front.

Still, be careful and make sure you have it secure before moving it. Even though its heavy it can slip.

I only use one to support the tt, tranny and diff.



Only used one when we did this one as well.

I used an ATV jack and a floor jack to pull my MN-6 and rear differential. It was a good combination for my home-garage clutch replacement.

I used an atv jack and a jack stand to lower - then once everything was clear I was able to push the atv jack by holding the front of the torque tube up. I didn't use in straps but will the next time. I used 2x4's on either side of the trans to help stable it.

Wondering what the advantage of dropping the rear cradle separately is....I know, I know, the book says you HAVE to. I didn't...

Once you pop the driveshafts out of the diff you can fish the brake lines up and around so you dont have to deal with them...then lower the whole show as one unit.

If it were me on my back, I'd use some sort of second jack. Maybe if the cradle weren't there, maybe I'd try stabbing it without a second one. Frankly, the cradle allowed me to use the sway bar like a bicycle handlebar and drive the whole assembly back into place...

I presume you're referring to Patches's picture. He did that because the rear cradle is too wide to drop down through the (4) post side rails.

I think it depends on the work environment. If you have a lift and a tall tranny jack, dropping the whole assembly is easy. I've also done it on jack stands, and it was a lot easier to manage dropping the pieces individually, especially when working by myself. I have also found it easier to get the torque tube stabbed with just the tranny/diff attached to it. Not having the cradle mounted gives you more space to work, and makes it easier to maneuver.

Once the torque tube / tranny / diff is stabbed and bolted in, you just hold it up with a jack stand under the tranny while you raise the cradle into position with the tranny jack.
