LIMO: is it necessary to drop the engine out to replace a single mount? I have one mount in particular that is buggered and ideally if I could just take that one off and replace the perished rubber with urethane, I wouldn't need any help (pay anyone). It's the front mount infront of the transmission - which I imagine is why power transfer (acceleration or decelleration) makes my car clunk and jerk when I put my foot on or off the pedal.

I haven't increased the power output, so I don't care about increasing the strength of the mounts themselves, but rather, replace the bushing with something more enduring.

What's the reason for needing to drop down? Can't the mount be removed if a bit of upwards pressure is placed on the tranny (ie jack with wood chuck)?

Does anyone know roughly what the difference in flexibility is between the OEM rubber bush and 50A, 55A etc?
