    FYI: This process is different if using "MOST" brands of aftermarket factory replacement engine mounts. Most of them are already mounted in that metal sleeve. It's mainly with polyurethane mounts that you will have to drill out the original mounts to reuse the metal.

  • @glennmanchester1568

    I would have sworn I've bought the whole assembly all together already and never drilled them out but they were just direct replacements and not polyurethane mounts so nice job

    88-98 k1500 4x4 is a little easier but that size 15 ratcheting swivel wrench does help out a lot I did one side without it took me about 3 hours other side took maybe 1 hour with swivel ratcheting wrench what I did was I removed 2 bolts on transmission mount first then remove that long bolt that hooks up the engine mount to engine once I removed that I lifted the engine and transmission with a jack and thick plywood under the oil pan and flywheel housing like 3 inches the you have enough room to remove the 3 screws holding the mount to the frame it's not a easy job but its possible for a DIY person.

    The reason those mounts are designed that way and why they are such a pita to change is back in '71 GM was forced to recall 6.7 million vehicles due to a rash of broken motor mounts that stretched way back into the 60's. The mounts would separate letting the engine raise up jamming the throttle and in many cases pulling the vacuum brake hose loose killing the power brakes and creating a major safety hazard. As result of the costly recall engineers were told to redesign it and make it bulletproof. This over designed mount is the result, this redesign is overkill but no matter how worn, cracked or loose it may get it can never separate and let the engine come up off the frame and become a safety hazard. The mount is extremely well engineered from a function standpoint, but the downside is its a real pita to change in a complete car. I had a '66 Impala that had the problem, they even tried issueing what they called "safety mounts" that were the same original design but with metal tabs that stopped torque from pulling the mounts loose, but eventually the torque just bent the tabs and you again had a stock mount. These mounts are indeed impossible to pull loose from the frame if installed correctly with good hardware. Ah the good old days. Heres a link to the NYT story on it. >

    Thank you for clear speaking and concise instructions. I am taking out the 6.5 diesel out a 97 Silverado 2500. These engine mounts are a challenge. The pass side is a breeze, but the other side has the front diffential in the way. Coming off.!!!! Wish me luck. I will let you know how it goes.

  • @JRobert111111
    @JRobert111111 5 лет назад +2

    The engine mounts on my 94 Astro were a complete PIA a few years ago too. Had to figure out the "secret access holes" to get a socket or wrench into. I didn't do any drilling, just replaced the whole thing. Even though the ACDelco mounts are a lot more money than the AutoZone mounts $10 versus $40 and both are made in China; there is no comparison when comparing them side by side as to the better quality of the GM mounts. Luckily the transmission mount isn't hard. Good luck!

  • @emmett442
    @emmett442 5 лет назад +3

    There's a method do drilling and not breaking bits or boogering holes: when you feel the bit is about to make its way through the back side, ease up on the pressure and increase the speed and let it cut the thin material remaining. Else, it breaks through rather than cuts through, and bites. That's when the damage is done

    • @luvspus69
      @luvspus69 4 года назад

      Just use a step bit to cut the head, flap disk to smooth it down, take 4 bolts to compress the unit and tac weld the rivet holes. That is how I did mine.

    Use a 1/4 9/16 or ect socket attached to a swivel works wonders. Also have used a wobble extention in series. Tape can help the bolt / nut stay in and even taping the swivel can limit it's movement. I never had to much an issue doing this method.

Try that next time. spread the word cause every mechanics video i watch they all use oil or like in your case WD-40. I like your old school videos. Rite ON

    What does it look like when the rubber is pulled off? I really want to see what the metal piece encapsulated in rubber looks like. Maybe the rubber can be shed using a wood chisel and your hydraulic press. An Arbor press might be better. I don't go camping anymore or I would take one and throw it in the campfire. Don't picture my campsite as being inside of a pine forest. My campsites mostly are in the desert where you would be lucky to see anyone else in a couple days. I live in an upditty neighborhood and I think the neighbors wouldn't take too kindly me lighting one of these on fire even for a YT video. Believe me in my younger days I might of LoL No YT then. Oh BTW drill through the Head of a rivet not the Tail. Give it a try. I know, I know the hole was not important but it's good discipline to do it right. I have drilled out so m any rivets in aircraft where I couldn't leave a trace a rivet was ever removed. I'm subscribed, thumbs up all your videos. You have a great channel, I've learned a lot.

      Are they still doing ok? I've heard the $6 ones don't last long.

      @@cj8172 Yeah haven't driven it much but so far so good. They were identical to the originals, and the rest of the project was big bucks so.. If you aren't on a budget I would definitely recommend going with better quality. I had to replace all the welsh plugs, rebuilt the trans, a ton of other nightmare jobs..lol
