How to Replace TOYOTA / LEXUS Motor Mounts (GS400 V8 shown)

On this episode I'll show you how to change your motor mounts. On TOYOTA V8 and V6 vehicles, you really need to keep an eye on your motor mounts. A simple "wear" test is to lightly power-brake your engine with your hood open and to watch the engine. If it "clocks" excessively or even "bangs" and makes a metal-to-metal sound, you may have worn or busted mounts. Worn or broken motor mounts can cause excessive vibration, excess strain on wiring and hoses due to the engine clocking too far, and they can decrease throttle response.

You'll need a good mechanic's set of tools and a safe way to lift and secure your vehicle and engine so you can manipulate the subframe and motor enough to change the mounts.

I still can't believe you manual swapped your gs400, keep it up man these videos are deadly

[NolanMotorsports]

Nice job! I was planning on doing the same exact process as outlined on the Club Lexus forums. I actually was able to find a super easy way to get to the mounts instead. Just slid the alternator and AC compressor forward. I documented my process and made a video. Hopefully this helps this intimidating process that much less intimidating. Keep up the good work

[singprb]

Perfect. I've been meaning to do mine but have been intimidated by the job. This will def help me get them swapped out now. 200k miles (still) on OEM mounts probably!

[FixingAndFlipping]

You overthinked it 😅.
When I did mine all you had to do was unbolt engine mounts from subframe. Raise the engine, then raise the side you working on little more. Unbolt 4 bolts from engine and take it out. There was one tricky bolt out of those 4, but with right tools it's coming out.
I did the same on ls460 even thought All Data says remove the engine 😅.

I got my engine and transmission mounts replaced (oem) 6months ago at 265k. Oh man, what a difference. Feels like a solid Lexus again. Right out of the factory.

[Ghost-Of-Kyiv-]

Did mine like 4 years ago I thought the car died when I was at lights it had zero vibrations. What a difference, u got balls for being under that lift lol I couldn't do it...

[ToffeePeanuts]

Very jealous of how clean your undercarriage is. My lower (probably upper too) oil pan gaskets are leaking, and I'm pretty sure my power steering lines are leaking too. It's quite the mess

[johnleto]

Very cool! Will be doing this on my GS at some point.

[daniellucatero-jimenez.]

You are the GS wizard thanks a lot for sharing this. Just to clarify you only had 2 subframe bolts to loosen & the 4 on the transmission mount to get the engine to drop? Going to do this on my lift tomorrow hoping it won’t take too long (i’m only replacing the drivers side).

[joecox]

Thanks I got it, this would be most practical video for GS300/400 motor mount.

Did you also replace your transmission mount? If so, what brand did you use? I currently cannot find a Megan Racing transmission mount online. I just purchased a well-maintained, completely stock 99 GS 400 with 103, 000 miles, and it has been a great car in two months of ownership. I changed the timing belt and will do this job next. Thank you for all your super informative and helpful video content.

[mrdebonair]

How do you like the mounts compared to oem I’m stuck on if it’s worth it the money or if Megan racing is just as good

[iceman]

I also wanted to swap my engine but I couldn't figure out how to remove the motor mounts. So I ended up paying a mechanic and made sure to replace everything necessary that I could possibly imagine. Unfortunately, the oil pan started leaking months later and one side of the oil pan is right under the engine support. Darn!!! That just made it complicated. So I've been trying to find an easier way to fix it and for sure I can't use your method of supporting the engine on the oil pan for the obvious reason. I think an engine support bar should do the trick right? Do you think I have to remove or just loosen the engine support and loosen the motor mount as well? I'd really appreciate any suggestion on how to tackle this project so I can get my hands dirty since I just spent quite a bit on the car.

[MrLboogs]

Good thing I've done my engine mounts while I had my engine pulled

[tjmax]

If possible, could you please expand a bit more on the NVH. Really looking at this for my 03 430 but I’m concerned with how it may feel. I don’t mind a 10% or so increase in vibration.

[tedlu]

Great video! Wonder if there is any videos on replacing the motor mount of LS460. Thanks a lot

[MissouriMatthew]

What orange hydraulic jack stands are those?

[GryzzliBear]

I’m looking to replace my left and right motor mounts and transmission mount on my 2006 Lexus IS250 AWD. Is this similar to the video I just watched?

[justincooper]

How do you like the Megan mounts? It’s been a while.

[Jack]

Is there any more motor mount at the rear side of the engine?
