Replacing my motor mounts, how to drop the front subframe?
Hey clublexus. It has been a while since I have posted on here. I tried to change my motor mounts on my 96 sc300. I got the supra mounts part #12360-46111. I followed this thread which was really helpful, thanks @motorheaddown. Can someone explain how to remove the subframe? It seems really straightforward, I spent 5+ hours trying to get the subframe down and no luck. I gave up cause it was 11pm by then and I had been working on it since 5pm. This is the thread I used to help me get the part numbers and the procedure.

Would have been much easier to get a engine hoist......undo the 2 bolts for motor mounts in the subframe, pick engine up with hoist and put new ones in....
Or if you dont have access to a hoist.....undo the 2 bolts for motor mounts in subframe....and jack up the engine from underneath
Why are you dropping the subframe...you dont need to do that to change motor mounts
Do like this guy said at the bottom of the link you posted

Initially didn't plan on dropping subframe.

K seems like this is the way I will approach it next, so remove the nuts on the motor mounts, then support oil pan with piece of wood and a jack and remove brackets. Do you know if the exhaust manifold also has to be removed? It was dark when I was trying to do it and can't remember if there was another angle I could approach it from.

I haven't done it in with the stock exhaust on there but I would say its possible, you may want to reach some of the bolts from underneath on the front side if you remove some of the plastics which will have to come off to jack up the engine from the oil pan anyways. just get a breaker bar and maybe a swivel socket and go at it.
I might even say break the bolts loose if you can while the mounts are still attached and engine in place, otherwise if you do it after jacking the engine up its going to move around on you and be that much harder to break them loose, probably dangerous as well since its just supported by a jack at that point. do not remove the bolts fully until engine is supported, I would probably support it with the jack and a piece of wood under the pan, crack the bolts loose, the undo the mounts, then jack the motor up, then undo the bolts on the brackets (The ones you broke loose at the beginning). you can really do it however you want just try not to drop the engine on yourself in the process.
Def the intake side (drivers side) does not need to come off, the passenger side I think it can be done without taking the exhaust manifold off, but it might be a little tighter in that area. still worth the trouble though.
