DIY Engine and Transmission Mounts Replacement
For sometime now, my 93 LS400 has been manifesting untolerable increased in vibrations on regular driving and freeway speeds. It is not the way a Lexus should drive. I remember when I first bought the car. I could hardly feel the engine running where I sometimes accidentally restart the car . The transmission shifts so smoothly too.
I just finished the procedure about an hour ago and it took me a total of 6.5 hours including taking pictures and breaks in between.
I have not seen any DIY with some detailed step-by-step procedures with pictures on the board and on Lexls' site so I will post pictures and procedures of the replacement process after I clean my self becuase I am covered with grease.

DIY Engine and Transmission Bushing Replacement
Tools and equipment needed:
1. Toyota OEM (2) engine bushings
2. Toyota OEM (1) transmission bushings
3. Floor jack
4. Jack stands
5. 2x4 wood blocks
6. Adjustable wrench, and metric sockets (mm):10, 12, 14, 17, 18, and 22.
Raised the car using the floor jack and place all four corners in jack stands. Remove the front wheels. Make sure the car is even on all corners on jack stands. I decided to work on changing the engine mounts first.
With the 2x4 wood block on the jack's lifting point. Place them under the oil pan and lift the engine slowly until it is raised ~0.5in...
Using a 10mm socket wrench remove the bolts that holds the wire harness...
When planning on how to remove the engine bushings, I decided to remove or lower the cross member because the steering column is on the way and there is not enough space on the driver side to access the engine mount.
On the lower control arm, there is a camber adjustment bolt. Get a marker or Sharpie to mark the relationship of the bolt to the cross member so that you will not miss align the wheels when you intall everything back...
Using a 22mm socket, loosen the nut and camber bolt.
Using a 17mm socket wrench, remove one sway bar end link nut and the lower nut/bolt that holds the strut. Remove all the nuts/bolts that holds the cross member, lower engine bushings nut, and power steering rack. You are now ready to pry the cross member down through the lower control arms and you should have something like this...
Using a 17mm open/close wrench, you need to access the upper engine bushing nut. This is difficult so be patient and use your creativity without breaking other parts...
Engine bushings removed...
Common factor in abnormal vibrations, damaged engine bushings...
Install the new engine bushings...
Once the engine bushings are in place and the top bolt are tightened, you may install everything in this order: push cross member upward and hand tight the nuts, lower engine bushings nuts, power steering nuts/bolts, lower strut nut/bolts, sway bar end link nuts. Now, start tightening all the nuts/bolts.
Now, find the mark that you made on the canber bolt and align them and tighten the nuts.
Here are the engine bushings with everything installed...

so u took a great looking car and totally trashed it, toyota spend millions on designing the ls to look so cool, so what makes a guy with a couple thousand bucks think he can do a better job, most of the guys attempting to make the car look better end up with something as ugly as we r seeing in these pics

hey Garage7RP, PM a mod, you should really make another thread for your DIY, its similar enough to what's needed for the UCF20/21 that i'll throw it up on the UCF20 FAQ Sticky.
