Subframe Assembly

Anybody know how to remove the sub frame assembly on a 94 SC? . I have to do motor mounts and the oil pan, front & rear seals. This sounds the easiest. Any help or insight would be appreciated. I have a manual but it is pointless, just points to the suspension section. Thanks
 
I wouldn't do all that. I would take off all accessories up front. Unbolt the motor mounts, jack up the engine enough to get to pan and get it out, then put mounts and pan in and put all acc. back on.
 
I have to disagree with Aaron on this. I have done motor mounts and found that if you support the engine from above, unbolt the motor mounts, the 2 small clamps that hold wires and lines to the subframe near the strut rod mounting points and the 8 E18 inverted torx bolts, motor mounts are a breeze. The job can be done in about 90 minutes without air tools and without lots of cursing and screaming. You will need two dowels of the proper size (dont recall them off the top of my head) to realign the subframe using the alignment holes which are there from the factory and a torque wrench for the resinstall. Th pan can be totally removed from the engine bay as well if needed (which I recomend as I would thoroughly clean the inside of it while its off as a precaution.

I tend to spend a little extra time to get a clear, easy line at things instead of banged knuckles and frustrating bolts you can't get to. Besides it only takes 20 minutes or so to get the accessories off and then motor mounts are simple.
 
The best way. Is to remove the cross member.
THROW IT IN THE WEEDS.
And replace with a tube k-member & a-arms

I think step #4 on that list of procedures is the sticking point for most of us that decided to do it from the front.
