The Dreaded Motor Mount Swap Was SO Worth it! (Celsior / LS400 Restoration Project) 

You are a brave man. Motor mounts is something I would pay a shop to do lol. Loved the water test. I'm gonna try it on my LS 430. It's an 06 with only 80k miles.

Did mine this year. At 185,000, the original mounts were shot. They were completely broken in half. Motor mounts did not fix the vibration so I continued the project by replacing the transmission mount. It was also broken in half. Had to Jack the trans up 2 inches to line up with the new OEM mount. My jaw dropped when I started the car. I had to rev it and look at the RPMS to know it was running. Night and day difference.

I love your invention of the "suck-score" . ...I wish that I'd written down all of my (96 LS-400) repair scored on an old Amazon box with Sharpie over many years...

Check your flex joints on the drive shaft. 🙏🏼🙏🏼

Thank you very much for making this video. Will be following your guidance on my 95 Celsior and stoked to poke around your channel for other Celsior vids/guides. Planning on doing the motor mount and trans mount at the same time, hopefully will save some time now that I know what I'm looking at. In case you were curious, the alt can be swapped fairly easily from below if you ever need to. I upgraded to the 430 alt this way. Just unbolt that power steering line like you did and fanagle it out the bottom after undoing the wiring and belt. (Make sure you install new wiring and a higher rated ANL fuse).

Just found your channel tonight man. Amazing stuff you’re doing here. I’m a Subaru nerd but a few months ago started restoring a GT4 ST-185 I inherited. Throughout that process it’s become abundantly clear that Yoda engineers are absolutely brilliant, especially for the era my Celica is from.

Hello JJ, Here in Australia we use a 50 cent coin which has twelve small straight egdes, so it won't roll if balanced on its edge.....if the coin stays upright on its EDGE on the plenum while idling, the engine speed and mounts are good. Other Lexus ads on TV had a record player in the boot playing as one drove along....I haven't tried this of course!!! Cheers from sunny Australia!

props too you i took mine to a shop had them put a new power steering rack and lines with motor mounts 155k 98 LS400

you really worked with determination, and the vehicle has been Restored to Factory feel....looking forward to possible improvements in real suspension... how about the rubber connections on the drive shaft????

Dude, was rooting for you when you tried to take out the mount. Also, screaming at your for turning the first nut the wrong direction. We've all been there. I recently did that on an outer tie rod bolt and broke it! Had to take it to a mechanic to drill it out.

i love the ls400 2000 one of best cars ever made i own 1998 toyota Avalon almost the same car om getting ls400 in a year or soo love em

Nice job. Looks like somebody changed all the OEM hose clamps to those worm drive screw on type. No bueno. I would swap them out for the OEM Toyota hose clamps

Bro, you’re not the only one tightening nuts by accident. I’ve done it countless time and think how much of an idiot I am 😂 By the way, could these be causing the vibration during idle (when in gear) and vibration during the transition from 1st to 2nd gear ?

Not looking forward to this. I haven't seen a good video yet though, and yours will help me out massively.

Hey JJ, where do you find all the proper torque numbers?

Good video, you need some external mic! Keep it up!

did this solve your clunking/jerking when putting the car into drive? if not have you fixed that issue? happening on my 1996 ls400! thanks !

How many miles has it? It’s really good condition!

you need to get yourself a milwaukee 1/2 impact, makes life easier
