Technique for Changing My Diff Mount

Post by sansouci » Tue Jun 12, 2018 5:43 pm

My 84 633Csi/auto needs a new diff mount. Two possible techiques but I want to know which is best:
If I put the rear up on ramps, I may be able to put a small floor jack under the diff to manage it.
If I put the chassis up on jack stands, that would unload the rear suspension and then use the floor jack to manage the position of the diff.
Which is the better, safer method?

84 E24 633Csi Auto, Bronzit/PearlBeige 6997510
93 E32 740il M60 Auto, Alpenweis/Ultramarine
60 528i M30 5-speed Green/Beige (crushed)
71 240Z 4-speed White/Blue (rusty & sold)
65 396 Chevelle 4-speed, Marina Blue/Black (stolen)

My method:

Jack up the car by the diff. Insert jack stands under the subframe rail that goes all the way across the car, just inside of the dogbones. Lower the car on jack stands. Support diff lightly as the differential bolt is removed. Remove diff mount hardware and replace.
