So I was able to lift the engine and remove the oil filter and replace the driver side mount. But I cant even turn a tool on the top nut of the passenger side motor mount. Any tips? Tools, angle, anything. I was able to get an open end/ closed end 17mm on it. With the closed end that slightly angles on the nut. But then I couldnt move it in any direction. I know it can be done, it has to get tightened and installed somehow. Do I need to take the alternator out of the way?

How curious just had my mounts replaced. My mechanic replaced them for me. He charged me 150 for labor. He said it wasn't easy but wasn't hard either. Anyways here the old mounts.

My driver side looked just like that.

Well as u can see mine where completed shot. Today I will test the car and see how it feels. I haven't drive it as my wife pick the car last night and it's been park since the pick up.

I did run across this thread. Unfortunately it is based off of a GS300. The 400 has less room for a tool or so it would seem.

I still need help with this if anyone can lend some tips.

I wonder if a crowfoot wrench like this would work?
Closing in on 250k miles, I know I'll be doing motor mounts soon.

All, I was able to get the motor mounts swapped a few weekends back.

Probably ~3 hours from start to finish. I discovered a much easier way to get these out than dropping the subframe. I had to slide the alternator and AC compressor forward, then access was easy.

I made a video and posted it on my youtube channel "Nolan Motorsports" and the video is called "Lexus GS Motor Mount Replacement - Lexus GS400 (1UZ-FE)".

No special tools were required.
