Im trying to change my motor mounts but cant find the rear engine mount. If anyone can help me locate it and tell me how to get to it l would surely appreciate it ....

In the rear, lol sorry

Call your dealer and ask them or look in your maunal or try asking someone on a lexus forums..

It is located on the rear of the engine on the passenger side. The right side axle runs through the bracket connected to the mount.

on the rear of the engine
LOL
if you can not find the mount you want to replace and do not have the skills if you do take the car to someone that knows what they are doing
