stiffness of the rear subframe mounts?
 

hello gang,

Was looking at my rear suspension parts when I had the wheel off for some inspection and noticed that when I put a prybar between the subframe and chassie the rear mounts only flex a few mm but when I do the same on the ones mounted in the front of the subframe they flex a good 10-15 mm without using a lot of force on the prybar.

Aren't they supposed to be equal in elasticity?

I took some mental notes when I was digging around there and I reckon I can replace them by lowering the subframe about 3-4 inches in front and pressing the mounts out. Does that sound reasonable?

The front mounts on the rear subframe are "liquid filled", & they should give more than the rear ones that are solid rubber.

did some more testing
 

with the car back on wheels I seated a helper behind the wheel and myself on the ground and had him put it in and out of gear in order to create some forces in the rearaxle assembly.

These bushing are the first thing i can see flex when shifting force directions which means the whole subframe is moving up and down by about 15mm total.
Surely this cant be normal?
