Cross Member Part 2/Rear Transmission Support:
As I designed the cross member, two things determined the height. 1) I needed adequate clearance between the bottom of the transmission and the top of the isolator bolt and 2) I wanted the front drive shaft to be level from the front of the transfer case to the center bearing. It turns out that the front drive shaft was the determining factor.
I decided to make the cross member of 1/4" plate. It is 1" thick and 8" deep. The depth allowed me to put the transmission support where I wanted it and allowed the center yoke of the drive shaft to fit around the transmission.
Here's the first mock-up of the cross member:
Here's the cross member installed:
I made the rear support for the transmission in a wishbone shape so that I could incorporate all three support studs on the rear of the transmission. Here it is with the standoffs tacked in:
I used a single poly isolator, the same one that I used for the motor mounts, to isolate the rear support from the cross member. Here they are assembled on the work bench:
Here they are installed:
I'll work on the front drive shaft next.
