Greetings fellow creator and GP owner. Got the job done with a helpful tip from your video. Which was to loosen the 2 outer bracket bolts from the side with a ratcheting wrench which made it straightforward. Last time around I was lazy and bought a complete kit and had a shop do the labor only for $150. The lower front mount then crapped out @ 13 months, just 1 month out of parts warranty. If I may add 2 tips for others needing to do this that I didnt see any other video mention to ease a few things: 1) Buy a front mount from a local parts store with a lifetime warranty and make sure to retain the receipt. You will more than likely have to replace this again especially with SC trim GP's. Learn to do it yourself so if that's the case your only out an hour or two of your time but won't cost you a penny when it breaks again. 2) After getting the bracket back in place first with the 3 bolts slightly loose (which is easy and will avoid cross threading the oil pan) when you go to lower the engine the bottom mount studs will not line up with the holes in the subframe. Tried pushing on the motor itself up top with a crabby helper but I found it can be much more easily done solo by maneuvering the jack itself to position the studs first before lowering the engine back down.
I would also like to add i didn't need engine mounts at all. there is a bracket between the transmission and the engine, one end screws into the oil pan and the other somewhere up on the transmission, mine was lose and missing a bolt causeing an annoying rattle/vibration. If you have this issue check this out.
doin this job was a beast, I really didn't think i was gonna get it done but its done. My mounts where fine and i still have a mystery rattle I can't identify though
I have now done this job twice because i bought the cheapest set of mounts a could find first time and they were junk and have notes. First time around I listened to some other youtuber had me take just the two bolts out of the top of the main mount without taking off the bracket and man was that a pain in the ass and incredibly hard to get lined up. Don't do what I did listen to Doyle and take the bracket off much easier all around. I would add do not take off the upper "dog bones" to do the lowers it's easier to get the lower main lined up with them in place, the transmission mount is easy either way. Have both a solid and swiveling end racheting wrench if you dont wanna be there forever with an open ended normal wrench.
Great video - this saved me tons of time! I finished both mounts in 45 minutes thanks to you taking the time to produce this video. Here's a tip I learned: Support the subframe with a jack and remove the two large 18mm bolts, then gently lower it onto a jack stand (not too far, the steering gear is connected to the steering shaft). This takes a few minutes but allows you to get right at those tricky engine mount bolts with a 15mm socket on a U-joint and extension. Super easy. The rest was exactly as you described. Quick safety note: I tried not to put my hands in between the engine and frame when the engine was supported by only a jack, and assumed the jack would fail at any second and smash my hand. THANK YOU!
QUESTION... how many mounts have a Pontiac Grand Prix 98?? my car screeches when I put it in reverse and the engine jerks so I think it's the mounts but I have no idea how many he uses.please help
@@SalemDoyle I have question I find nothing about this problem at all on youtube or google. My car has a rattling sound I almost fixed it, but it only rattles when I'm slowing down or at a complete stop. When I accelerate the rattling sound goes. I'm at a lost. It was louder but I found out that the oil level sensor wire came apart cause it wasn't wired right so when I did that the rattling noise went almost all the way away. But I'm stuck right now.
Thanks for sharing this, looks much easier than I thought it would be. Have a 01 GTP that rattles at red lights. Thought it was the torque struts, so I replaced those. Popped the hood a month later now they're bent sideways lol. Gonna do it all (except core support torque strut bushings because I forgot to order them) today.
..And we're done. The brackets for the L67 were a bit different (easier to get to the nuts holding the engine bracket to the mount) Pretty easy job, but I will add the fact that I used a lift and transmission jack at the shop I work at. Didn't get to beat on it yet since it's pouring outside.
What kind of mount did you get? I thought an Anchor front mount would be OK but it only lasted about 6 weeks and now my big vibration is back. I shimmed the mount to prove it and it's ok for now, but I want to put another mount in. Is yours An A/C Delco mount. I thought the Anchor mount would be fine for a few years, at least, but was bad in 6 weeks.
After watching this video, was a little surprised the engine mount bracket is entirely different on my 04 Comp G. Its U shaped and the front bolt almost touches the ac compressor. Didnt even see a middle bolt. Decided to leave the bracket on and take the mount out. Tomorrow doing the transmission mount. Thanks for the helpful video
my 01 gp was different also I wish I never took the bracket of but Houghton I would need the room.i got it done it was just hard to line the bolts back up for the bracket. but I got it done.
Factory says to remove the flex pipe to the catalytic converter I didn't do it and ripped that sucker like so many other people do because of RUclipss not telling you to do it
ive seen it happen and it can, but usually its the cv axles that cause that wobble feeling. I have brembos on my 3800 and i think the 14.1 inch rotors can cause a bit of a wobble feel as well. Axles are in decent shape from what i can tell but I have a similar highway wobble like tires are out of balance. Im not sure if its a good test but with the car in park if i try to push the car forward or backwards the engine does swing quite a bit, seems like the mounts are barely holding it in place. mounts are relatively cheap ($200 ish for both) so if they are old and have some decent mileage on them, it might be a good item to add. Plus if you are doing it yourself, its not a huge labour cost to experiment with. Axles are even easier to replace, just make sure you use oem cv axles or a repultable reman, ebay stuff is absolute junk. I had some put in when i was a noob and within 6 months they were falling apart and felt very solid vs the nice flex the oem ones had after years+mileage of use.
Do all engine mounts have that bracket on the grand prix, cause mines didn't have that bracket it was connected to the bracket behind the harmonic balancer.
@@SalemDoyle I got a question my car feels like it's being pulled when I accelerate. I replaced the mass air flow sensor, but the pull got worse and my car started stalling, so I put the old one back on. I changed the both oxygen sensor and fuel injectors, but I don't know why it's doing that. Can you help me out.
@@SalemDoyle yeah the only code that had popped up was a P1134, but I replaced both oxygen sensor, but I feel like I should had got the heated one's instead of the regular ones.
Great video. I did them both the other day just 'cause I was tired of hearing that telltale clunk when putting it in reverse, but the difference it made in terms of handling and acceleration was considerable. The trans mount especially looked like pancake lol.
I have an 04 GTP and when I first shift into reverse or drive, the car will rev up but not catch. Eventually it catches but it comes with a rough jolt and loud noise. Do you think this issue could be caused by worn mounts ? Or could it be a straight up transmission issue?
@@SalemDoyle I appreciate the help so much man. One last question; any advice on going about diagnosing and repairing it if it would be an internal pressure issue ?
I have a 2006 Pontiac G6 GT 3.5 2 door coupe. My rear mount is bad. When I go to find parts it either comes in a set of 3 mounts or 4. Not sure which I should get. Also would this video work with that car and the steps to take?
@@SalemDoyle Yeah and unfortunately I could not find a video on replacing motor mounts for mine. I was hoping it'd be similar enough. Oh well lol Thank you for your quick reply though!

Lol.. sign me up
Thank you brother for the information 👍🏻 and the video
Such a different s when u put in new ones for sure .did mine so much stiffer ..
I couldn't believe what a difference it made. Mine were so old that replacing them reduced body roll around turns by at least half.
Awesome vid man, very helpful. Thanks

Oh is that a polyurethane mount? If it is a polyurethane mounted it give you any vibration at idle or anything?
@@mrbreezeet1 no, stock
hey what was the transmission mount you used? should i just get one off zzp. the zzp one looks different.
I used the gtp specific one from rockauto. I just like that style better

Great vid man cars r looking sweet .
Will a bad motor mount cause any vibrations while driving making it feel like a tire out of balance? Or something similar
Not usually. But a bad axle will while you are accelerating.
@@SalemDoyle what about a control arm bushing? The problem occurs at cruising speeds.
Sometimes if the bushings are bad enough

No problem. Good luck

Yes.
@@SalemDoyle appreciate it. Another question would a bad transmission mount cause my Pontiac to shake/shudder feeling when I turn it off
Possibly. Usually if the trans mount is bad. The lower engine mount is too.
@@SalemDoyle just replaced the lower engine mount but didn't have the extra money for the trans mount. Gonna have to give it a try. Thanks for responding
@@SalemDoyle is there 2 different styles of trans mounts for it cause autozone has 2 different ones on there website and not sure which one to get
Is it super hard? Ive done breaks, ps pump and lines and a few other easier things. Ordered a mount fot my 08 3.8 gunna try it myslef
Pretty easy. You should be fine
just support the engine well have take your time, wont be hard if you have done general work on your car.
Now replacing the oil pan is fun on a 3800, even more fun if its the aluminum pan like mine (replacing seal, not pan).
Does this method work on the 2001 pontiac bonneville?
Should you get a alignment after replacing the mounts?
No, doesnt effect the suspension
My car jolts when shifting, and when going from park to drive. I just got a new transmission and disappointed. Is this a possible issue? When rolling and re applying gas sometimes it jolts too.
Mounts are deff. A possibility
@@SalemDoyle gotcha, thx for the advice
Take the transmission back and get a new "solid polyurethane" mount.
Again a good clean and simple video, thumbs up! is there a big difference to the 99 gtp model?
Only that you dont have to remove the upper bracket with the mount.
The very first one you did what was it called ?
Are you talking about the engine mount or the upper mounts?
CAN BAD MOUNTS CAUSE TRANSMISSION PROBLEM?
Not usually, but they can cause axle bind
The plastic pins half always break on me .so I go to scrap yard and grab some used ones ..my second home scrap yard
Junk yards are life savers
Any aftermarket poly mounts you might suggest? I’m getting started on my Son’s GTP and figure you already did a lot of homework on these .
The zzp ones are the best i see
My engine is leaning on passenger side. Would this be the issue?
It's a 98 Grand Prix
Yes possibly. The mounts compress when they get old.
When I hold on brake and put in reverse the engine moves forward,top mounts?
Never put the jack directly on the oil pan. You can crack your oil pan doing this. A piece of 2x4 works good though.
I've got an 05' Grand Prix GT. What do you think is the average cost to change those parts..........IF I buy my own parts?
To do mounts shouldnt be more than about 70 labor
@@SalemDoyle by watching that video, it kinda looks easy enough to do myself
Its not bad

Possibly.
Now do the oil pan 🤣 those are a pain
That is coming. The 99 needs it.
Salem Doyle all the 97-03 need it Grand Prix Monte ect and the last 2 bolts suck waiting to see if you know some tricks 😎
This is the noise when tapping the gas and immediately letting off. Do you think this would fix the problem? ruclips.net/video/5BIAB8L66dc/видео.html
hard to tell from the video, but that could be a mount noise. if the car is high mileage i would start there anyway.
