- Опубліковано 8 вер 2024
- 2008 Gmc Denali Motor mount is a common failure. This is the same motor mount on a Silverado, Tahoe, suburban, Yukon, and many other GM V-8 trucks. Engine will make a loud thump on acceleration. This video will give you an idea on how to repair it yourself. Thanks for Watching! Feel free to Ask Questions below!
If u are good at puzzels, u can just remove the inner tire fender and fish it out the side. Just had to unplug the wheel sensor n carfull around the brake lines n u good. Thats how i did it . no removal of steering shaft or cv knuckle
Are there any major problems with this vehicle other than those motor mounts???
Nice video I was able to get it done without removing axle . I removed heat shield from exhaust manifold steering linkage also removed plastic fender liner and that's where I Accessed all bolts with 2 swivels got creative said a few bad words 3 hour's later it was done.
🙏🏼 going to take it on when weather permits
It’ll make your truck feel new again 🔧
Did the vehicle jerk when turning slow and made it feel like it had transmission problem by any chance? I have a 2008 yukon slt and it jerks/jump a little when turning and the tires squill. I need help”
Same here. I need explanation!!
Im going to replace the rear transmission mount assuming there’s way to much movement causing the front motor mount to break. It’s my 3rd time and I’ve actually done the same process as everyone else here. Removed the inner wheel-well cover, removed the steering column & exhaust heat shield
Then lift the engine to get some clearance. I’m also wondering is there a durable motor mount. I’d pay the extra cash to avoid this labor.
I have had to replace mine 7 times and have had the heat shield on every one of them. At a loss. Have even done both mounts and trans mount at the same time a couple of the times.
Allen Daniher if it happens again, I’m putting an aftermarket solid mount. Really irritating to have engine bearing around
@@RaztechPowersports Any update on how well the aftermarket is performing?
@@kas2388 I’ll ask my father in law tonight and report back 👍🏻
7 times,something just doesn't sound right,we're the OEM motor mounts???
I'm on my 5th....replacing the driver side every year. Every year I think I'll sell or trade it.
Have a 07 denali. I have that problem right now motor rocking when I hit the gas.. guess I'm gonna try and replace it. #helpful
Bradley McGregory you can do it! No more thumping engine
I have the 6.2 denali awd its an 08. I recently replaced the driver side motor mount , and thanks to the knowledge provided by yourself and others here at youtube, the instal was a success. only thing is immediately after fixing it my transmission starts kicking of p0877-00 dtc code! could it be from the amount of time driving on a bad mount then after correcting the issue it somehow created damage to the tranny creating this code? Or possibly during the install i caused a disconnection some how within the wiring to the transmission ? I'm pulling my hair out!
Great video
Could bad engine mounts cause a shake while idle? and perhaps don't feel the shake when in drive so much?
I’ve done my 2007 Escalade 3 times and I can say the heat shielding doesn’t do anything for blocking heat I tried with and with out. You get 40,000-50,000 miles on a set. now it’s time for set # 4 very poor design I’m surprised aftermarket people haven’t come up with a better design.
Get creative with Josh Yeah I know they fall apart regardless but the heat shield has to help a little bit. Amazing how Gm could allow such a flawed design to be made.
Get creative with Josh I have an 07 Lade EXT, I’m gonna try the Hummer mounts...I read they hold up better
DJ Kadilac that’s s good idea. Is it a different part number?
Brad Raziano AC Delco part #25847739
They are better made with steel where the others have rubber that breaks down and separates.
DJ Kadilac very interesting!
Great video and nice truck! I recently acquired a 2007 and it is a nice ride, but had several issues, one of which was this motor mount. I was unable to get the steering shaft disconnected, so I had to go through the fenderwell, which made access to the block bolts "better", but the only way I could get the mount out was to disassemble the heat shield and bracket and then it came out. Unfortunately, I had to reverse the process to install which made it a challenge to get the two attaching bracket bolts torqued. I did leave the manifold heat shield on which contributed to the difficulty. All said and done it was a great accomplishment to get it done and the money saved! Your way is better by far. By the way, I wonder if the real reason for these failures is the Chinese low quality materials. I understand that has been the issue with steel, aluminum and bolts. It's actually a national security issue...from tanks, planes and ships to buildings and bridges. Mr Trump is aware from his construction days (his father taught him well) and now military intelligence confirmed it (see Qanon) hence getting back our steel industry (and others) was a priority. Our "politicians" and "news media" sold us out for a buck...or worse...it was intentional!
Thanks again for the video love the color, mine is Stealth Grey...looks blue in Sunshine.
Thanks man this was helpful!!
MegaMax & Storm Lancer glad it helped and thanks for watching!

How many motor mounts on a 2012 Yukon Denali
I have a 2004 Tahoe with the same issue. Replaced for a new one and didn’t put the shield. That was like 12 months ago and i had to replace it again last week this time i put the shield on it. Let’s see how long it lasts
Gustavo Guzman yeah I believe the heat just eats up the rubber. This Denali motor Mount is still holding strong 👍🏻
Did you get the OEM part? Because I bought it from autozone (made in China) and it has oil inside I don’t know if that makes it weak
Gustavo Guzman I bought mine from napa. Better warranty usually means better quality part 🤞🏻
I have replaced brakes calipers struts put an axle seals in the front just looks like a little more than I can do what do you think of small shop would charge me for putting in the drivers motor mount in Wichita Kansas
It’s a pretty straightforward job. Honestly it sounds like you could probably take it on. I would assume 3 to 4 hours of labor plus parts
Has anyone here replaced the rear transmission anchor mount. It’s probably the culprit of the motor mount continuing to cause the break / damage
I have a 2012 Yukon Denali and how many motor mounts are on my engine and I was told it has two motor mounts
Correct there are 2. Only 1 typically goes bad because of the upward torque on the mount. Rips it apart
curious what would cause the engine to not line back up after installing new mount? I changed my old mount and put new one on, but can't get it to line back up. ive tried both ways bolted it to block then tried lining up to frame and bolted it to frame then tried lining it up to block either way it won't line up. any helpful tips?
Did you change both mounts or just one?
@@RaztechPowersports just the one on drivers side
how to get the shaft apart?
Steering shaft?
Why do they continue to break. ?
Poor design and a lot of torque
Does the passenger side need to be changed if drivers is done?
Since the torque is only applied in One Direction. The other motor mount holds up pretty well. They don’t fail when they are being smashed downward
Genius!
Any other major problems you had with this vehicle,im thinking about buying one???? I just want a really solid SUV that's not gonna cause me any headaches....
Great suv but it did need a torque converter at 150k miles. I will say, my father in law runs it hard 🏁
@@RaztechPowersports Much appreciated my man...
Why does everyone on UA-cam only change one? If one is bad change them all
Torque. The engine is constantly pulling up on one and smashing the other. It fails because the rubber tears.
When you come to a complete stop then eventually let of the brake, did it ever make a huge thump, or when you go to accelerate it would make a couple cracking like noises?
Oh yea it sounds like the motor was beating around in the engine bay
Why remove the steering shift or the drives haft? Thats all unnecessary. You can simply jack the motor up and you will have plenty of clearance to remove the old mount and install the new one.
ctheisct pretty easy to remove for some extra clearance.
Not with all wheel drive. Transfercase makes it a b****
How much do shops charge for this job?
Undisputed Attitude I was just quoted 1500 for both mounts on my Sierra Denali
@@bigjig20 I got $250.00 or $400.00 ish for one side or both . I'm going to do mine my self and not mess with the steering column , I've seen it done .
Did my Suburban, yesterday took out the 3 bolts on top and 4 underneath but I jacked up my truck on the driverside catalytic converter had enough room to take out and put back the motor mount with ease...
@@RandomMind you jacked it up right on the catalytic converter? Need to do mine soon
@@mhaskins3769 yes...the job was hard to do...I saw someone else do it that way, and it does give you just enough room you need.

My 2007/8 SILVERADO 4.8L has this issue , I'll use polymer mounts and leave off the heat shield . the OE rubber mounts are proven bullchit . why waste the time and money on rubber ??????
Harry Tuttle if it happens again, definitely going with aftermarket!
@@RaztechPowersports I'm just disappointed . I feel these OE motor mounts should have lasted longer .
