Nice video. simple to the point and requires no pricey diagnostic equipment. This is the perfect DIY'ers repair. Good job Eric. -John

Love your videos. I’m active duty stationed in Hawaii and bought a island beater to get around. I have several things that need to be done to it and this is one of them. Keep them coming.

[@danseman1]

Nice video Eric. I even enjoyed your interruption from the office. Makes it more "life-like...real". Looking forward to more of you sharing your expertise. Thanks.

[@jwingo7257]

Dave denton You seem like a really regular, easy going guy. Enjoyed the video especially the “reach around ratchet”! Cool dog, nice real life interrupt by I’m assuming your wife.

[@Dugar1]

Hey Eric O. As usual awesome video. I'm a Certified GM technician and deal with these vehicle all the time almost 90 percent of the Lucernes that come through here have destroyed front mounts. I usually take the tripod and lift the engine high enough to clear the and time saved lol. I love all of your videos and keep up the excellent work bud. Oh a remember TORQUE IT TO SPEC

[@mericafreedomland3583]

another great video Eric and have a great thanksgiving to you and your family

[@schigara]

Eric, I just received my Astro Onyx 1822 Nano 1/2" impact a couple days ago and I just love that thing! I used it for the first job yesterday replacing the stock upper camber arms with new adjustable camber arms on a 93 300ZX Convertible and it was small enough to get in there and I did not have to use a manual ratchet at all. It made the job so easy. The IR 231c would never have fit in all those places to get all the nuts and bolts. Your channel is awesome and I have learned a lot but the exposure to your great taste in tools is putting a strain on my tool budget as I am spending a lot more on tools now. Oh well, who ever dies with the most tools wins. I am gonna pick up the Astro 1128 3/8 mini air ratchet next week. Keep up the great work. I have watched all your videos twice.

[@SouthMainAuto]

Astro is a great company I have found out. If you have any problems just call them. great people right in CA

[@BigDog50001]

[@pammyp3553]

Thank you Eric! Even though this was filmed in 2016, this is good solid information for 2021 ! Never knew this could happen to an engine bracket. Loved the close-ups and step by step...good video!

[@cjones4512]

Good to see videos again. I imagine you have been quite busy with people trying to get their cars ready for winter. I know I have been.

[@oreotcat]

Great job Eric O! Happy Thanksgiving!

[@SmittySmithsonite]

You have my ratchet! I've owned it 16 years now. The thing broke right out of the gate, so it sat in my toolbox for almost 10 years before I finally remembered to bring it to work one day and have the Snap-On guy replace it. It's been used almost daily for the past 6 years, and never misses a beat. :) I had a bad motor mount in my '72 El Camino for years. Every time I'd leave from a stop, about 1,000 feet up the road, I'd get a big THUD as the engine came back down on the mount (when I finally let up on the pedal, lol). It had completely separated from the engine. Probably put 40k miles on it like that, and only fixed it for the guy who bought it. :D Oh, and HAPPY THANKSGIVING to you and the family! CHEERS

[@SouthMainAuto]

Lol cool story man! Happy thanksgiving to you too!

I had a 68 Fairlane for two years in high school (84-85), and for nearly all the time I had it there was one broken motor mount. Every time I'd put it in gear and put my foot to the floor, the engine would twist and crimp the throttle linkage. As you can imagine, the car would have a mind of its own at that point and the only option to free the linkage was to shut off ignition. My friends got a real kick out of it. Incidentally, those were some tough motor mounts on the Fairlane considering how much abuse it took with a broken one.

[@djshortcutz]

thanks for the info at the end i believe i am having the lean problem on my 2011 wk2 due to clunk noise as well i applied what u said about thr motor mount and ur right the motor mount was shot thanks again brother

[@crystalcoleman8668]

I had all 4 mounts replaced in my van, like a mth ago , and all was good, then a week ago , I started getting that Clunk when I put it in drive . Just like before, I have heard they can go bad real quick if they are cheap ones , or if they are not alighned right ,

[@cpowerscpo2002]

another great one happy thanksgiving be safe god bless

very helpful, Thanks Brother

[@laohantun7404]

Great job mate.

[@Kurtdog63]

I tested mounts on 07 impala. As soon as it was put in drive, the engine moved/torqued A LOT. Did not even have to press the gas to see it was moving way too much. Symptom was vibration going down the road especially at certain speeds, 51 mph in this case. Already had tires rotated and balanced and did not fix. There are six mounts in a kit for impala. Some for motor, others for transmission. Thanks for posting.

[@63256325N]

Thanks for the video.

That was a nicely separated engine mount! I think I still prefer the high-mounted mounts from the older GM V6s, though. Call me crazy if you like~ Have a great Thanksgiving, Eric! :D

Mounts are a favorite of mine. Some can be a bit of a pain but since you can feel the difference when you’re done

[@BubbaIXI88]

that classic reach around move works every time

[@pospc2]

I had a bad mount on my engine. It actually fell apart when i was removing it. Like the top mounting plate was in the engine still while i was holding the rubber in my hand

[@FernandoRodriguez-ds5ri]

I have to agree with most, great video. I just wished that you had driven the car before so we could compare the clunky noise to our cars. Mine is a making a noise to, first shop I took my car to told me it was the lower arms, and the second guy at a different shop said it was my motor mounts, he did the same test that you showed on your video when you put it on drive, it did had some movement, all along I thought it was normal on most cars. Second I wish you could show the or compare the new motor mount next to the new motor mount for us to see the difference. All and all great video. Btw cool pencil like flash light. Thumbs up! Btw I own a Cadillac SRX 2011 Dallas Texas.

[@ericcorse]

Eric O Mrs O is never an unwanted distraction. Is the index-able ratchet a SO? I've got a1/4" but nothing bigger. Looks handy.

THANK YOU! ! !

[@TeemarkConvair]

brings to mind a friends 59 catalina; if he accelerated to hard the throttle/pedal went to the floor until the trans shifted. a fun experience. with my 17 year old enthusiasm i decided to put my hand under the linkage so i could stop the throttle from "flooring".. well, i STILL remember that experience! and the PAIN across my 4 fingers!

[@HAL-dm1eh]

You should have seen my 94 Taurus. You didn't have to guess. You could watch it clunk around in the engine compartment like a rock rolling around in there. Ford in their genius decided to give it a rubber mount filled with hydraulic fluid, which rotted away the rubber containing it. Was totally gone. When I saw it (while examining something else) I was like, so THAT'S why I have an exhaust leak. Engine was ripping the exhaust up!

[@inhaleanthrax1333]

David McClelland im having problems with my 2005 all tbe mounts are broken and all the hoses keep falling off because of it .. Never get a ex cop car

[@davestout8471]

The engine mount bolts upfront on those ford Taurus are known to back out completely. Guess how I figured that out.

[@gocars3210]

Ahh memories. Reminds me of my 97 & 98 dodge neons. Factory front motor mount was made of bubble gum. The fix was to swap out to the ACR unit. The rubber in them was hard as a rock. No vibration isolation at idle, BUT THEY DIDNT BREAK.

[@cw2lido]

Happy Thanksgiving from Iraq! My 06 Grand Prix GXP had that same issue with the motor mount in the front (different engine but same issue). Mine had split in half and I found out it was bad as I was taking out the motor to repair a rear main seal and address some broken exhaust bolts in the back of the motor since they are hard to reach, figured why not just pull the motor out.

[@chuckseger733]

Big Help!!!!!

[@northerntranquility1614]

Always great videos very informative .You are a great teacher,and I like you saying if I can do it you can do .Thanks again Dale

[@Michael-fw5ef]

1. Eric great video. I own a Civic and when I go forward at slow speed and when I reverse at slow speed, my dash vibrates and I think it is one of my engine mounts that needs replacing. Thank you for the instruction video. 1. Your wife made me laugh when she said................'Well if it is wrong, it's your fault'. My wife says the exact same thing to me when she isnt sure of something but wants to avoid making an error.

[@shanielclarke1210]

Did it stop?

[@Michael-fw5ef]

@@shanielclarke1210The sound went away, but I didnt do anything. It went away on its own. It is probably an engine mount that is going bad

[@chrisbaltazar6895]

Great video bro 👌🏻, shouldn’t you change both ?

[@alistairpowers8129]

Good job Eric, thanks for posting, Is it a Florida car? not seeing any rust

[@jimcapelli1431]

Excellent video Eric. I am trying to change mine (2007 Lucerne) I can't seem to get leverage on that top bolt using the swivel though. I am afraid I might strip it. Also, do I need that flex head ratchet for that top bracket bolt, or can I get by with a swivel and a short extension? It seemed like you broke that one loose easily. Please advise.

[@rejmonwilson]

I have one of that bent ratchet, husky made them, got mine from the Home. Depot years ago.

[@derrickwilliams8285]

Thank you so much I was lost

[@realworldmechanic]

way is everyone so critical on the small all stuff,maybe they should make their own channel, I think your doing a great job,keep it up. peace

[@arciefan]

Ev1 keeps talking about not removing that bracket. I'm guessing that locator pin and more than that, the stud has to go thru that bracket also has changed the game , to make it necessary to remove it now. I've changed that front one on older buick before without having to do more than remove the nuts and support the engine but not on a lucerne. Aggravating the way those mounts don't hold up. Excellent repair video as always and Happy Thanksgiving to all the SMA crew !

[@jasong5913]

"Yeah baby!" Spoken like a true mechanic.

[@CoopersAutomotiveRepair]

Good Morning Eric. Good work. Have you ever supported the engine. Then Support the front of the sub-frame remove the front sub frame bolts Lower the sub frame remove the mount. with out having to remove the bracket. I know your going to say. To much rust and the bolts will break off or strip. Right?

[@aviezek3072]

thanks for the video. i had all 4 of the engine mounts replaced about 4 months ago, and now i notice that when starting up the engine kind of shakes more than when the engine mounts were brand new. and also when i put in drive or reverse, theres quite a movement of the engine either forward/backwards. but when new, the engine barely moved when put in d/r,.. is that how engine mounts are like after several months..or have they gone bad?

[@shaneharrison4775]

Yeah favorite repair on a 87 eurosport sport sedan 2.5 liter had to change all 3 and the dogbone, same with the 92 pontiac lemans two door coup with a 2.2liter

[@frugalprepper]

Rear mont bad on these will cause it to vibrate like crazy at a stop light and I will cause the passenger axle to bind up up and go bad as well.

[@shahsmerdis]

Great video ! I'm i the only one that noticed this is an 06, and its not rusted through? Better yet no rust at all! -Happy Thanksgiving SMA! Hope you guys have a great one

[@timbabyak8143]

It's almost 1 am so I will test this out tomorrow on my 2004 Ford Expedition. My upper radiator hose keeps blowing off and I tried new thermostat , new upper hose, new coolant cap, flushed the radiator several times....But was wondering if my motor mounts are in need of replacement and that's why my upper hose keeps popping off.??? The first time it happened was when I really stepped into it in-order to get up to highway speed. Maybe that was when the mount or mounts failed enough for the first time. The engine will run for weeks at proper temperature and then she'll pop again... Never overheats either...just keeps blowing the upper hose...Hmmmm... Great Video

[@voongnz]

No threadlocking needed? Thanks for the vid.

[@jakeornot6306]

Well done. I do wish the sound had been recorded. Maybe for another video.

[@dam4274]

My son had a Neon. Don’t remember the year. Brought it in to the tire center to replace the motor mounts. They bought some cheap Chinese ones to put in and they both went bad. Had them replaced under their warranty. Car still made an odd noise. Looked up the appropriate video for the motor mounts and found there was a third mount under the battery box. I changed that one. Car still made an odd noise upon acceleration but otherwise ran fine.

[@darylzero3139]

Nice one Dr. O. We won't mind if you put out videos you have already done before, ie changing brakes, cv shafts. Each model must have little variances to getting er done. Happy Thanksgiving!
