I'm having this same problem with my 99 Diamante, passenger side axle.
Shop manual says to hammer on the support bracket, then to pry at the transaxle.
It moved out maybe 1/8" at most when I hammered on it, and it hardly budges at all when I pry on it.
Does it usually take a tremendous amount of force to remove these?
What kind of pry bar do people use for this? I'm trying a couple different sizes of demolition bar. Small one doesn't give enough leverage and large one doesn't get in the tiny gap very well.
Would it be OK to use a chisel to wedge it out instead of prying? I'm afraid of damaging the oil seal if I do that.
