You can have someone check them. OR usually, when you shift the car into any gear you'll feel the engine or transmission kick. Thats how it felt for me anyway...

Were you having problems after replacing the front motor mount. If so check the air flow assembly from the air filter to the center of engine. If it has any holes or small rips it should be replaced. Look very closely at the rounded section while (moving it!) around. If you notice tears or rips it maybe letting eccess air into you intake affecting you response. If it has to be replaced it is a toyota parts containing the same number as the lexus part, but cost less money. Call around to toyota dealerships to get the best price. One other thing I tied a plastic bag around the ripped section, make sure it doesn't get burned or caught up on anything. Take your car around the block, you should instantly know the deal. car jerking at start offs, slow speeds and in lower gears almost certainly denotes motor mounts.

I just replaced the Dog bone mount and the front canister looking mount but am curious how hard it is to do the rear one(s)? Are there two of them, or just one? Can anyone direct me towards some posts on that, or how any info for me??

Thanks

With the engine running you lift up the hood and have someone hold the brake pedal down and you shift into drive, have them step on the gas. If the engine lifts up significantly chances are your
lower motor mounts are bad.

Best way is to watch the motor movement when shifting with brake depressed giving it some revs as others have said...thats how the techs do it where i work
