Need info for engine cradle change

I have a salvage 2009 mazda 6 and need to change the cradle as it had cracked. What all is involved? On most they say to support engine from the top but the engine mounts aren't attached at the cradle. Just the trans mount. Anybody have a walk through? Was thinking it should be simpler. My replacement cradle came with sway bar and both lower Control arms.

No need to support then engine - it will hang from the motor mounts as intended. I've done it countless times, but never written down the process. From memory, here's how I do it:


Drain the tranny
Disconnect swaybar end links
Unbolt steering rack and wire it up to support it
Disconnect control arms from sub frame
Pull axles out of tranny and control arms out of subframe at the same time
Disconnect power steering lines clipped to subframe
Disconnect dogbone tranny mount
Unbolt and lower subframe.


Here's some pics:
Steering rack



Subframe out - everything else hanging



Probably have to deal with the exhaust too.
Good luck,

Looks like you were doing a trans change. I just have to change cradle.

No - For me, it's easier to pull the axles than to separate the ball joints. You either have to separate the ball joints or disconnect the control arms from the subframe. If you chose to disconnect the control arms from the subframe, you have two choices:
1- pull the axles so you can swing the suspension out of the way
2- try to lower the subframe and wiggle out the control arms at the same time. This is possible, but the reverse is impossible to do alone.


I have a lift, air tools, etc and have done this a half dozen times - I can probably swap the subframe in 2hrs if I'm in a hurry and 3hrs if the shop TV is on and I'm sipping a beer.
YMMV


BTW, I've also pulled it with the entire suspension intact - definitely need a lift.

Thank you. It.went pretty smooth. Only problem I had was the bolts for the rack and pinion but after that, smooth.
