Is it going to make the engine vibrate more at idle?<p>Just kidding.<p>I am going to be swapping out my large upper mount bushing, as well as the engine mount bar end bushings (or whatever the hell they're called) this weekend.<p>I have searched and come across a number of ways to remove the large mount. Some have sawed and punched it out. Some just punched. Some have removed the mount, some not. I would appreciate your tips & tricks on what you thought was the most effective way to remove the upper bushing with simple hand tools. I don't have a bushing press or anything like that. <p>There was also very little info on any particulars for changing the engine mount bar end bushings as well. They seem pretty straighforward.<p>Any help is appreciated.<p>TIA.<br>

Re: Attention those who have changed the Large Upper Engine Mount. (needsdecaf)

Here are Evolve's instructions:<p>Engine Mount Bushing Installation<br>Tools needed:<br>• 14mm Socket with Ratchet<br>• 15mm Combination Wrench<br>• 18mm Combination Wrench<br>• Punch and/or Large Screwdriver<br>• Hammer<p>1. Remove the cross bar connecting the two strut towers and the upper engine mount. Locate the two bolts at the ends of the cross bar and remove using a 14mm socket and ratchet. Remove both bolts from each strut tower.<p>2. Remove the through bolt which connects the cross bar to the engine mount bushing. The bolt is 18mm on one side and 15mm on the other.<p>3. Remove the cross bar and set aside.<p>4. Using a large screwdriver or suitable punch, drive out the stock rubber bushing by striking the perimeter of the bushing where the bushing meets the aluminum housing. The rubber bushing has a plastic sleeve around it. Completely remove the rubber bushing, leaving the aluminum housing with an empty hole.<p>5. Insert the two EVOLVE Engine Mount Bushing urethane halves and metal collar.<p>6. Reinstall cross bar and tighten all five bolts.<p>7. Check tightness of all five bolts after driving for 60 miles (100km).

I used a hacksaw to cut through the plastic outer ring of the stock bushing. Highly recommended. You have to take the blade off, put it through the mount, then re-assemble the saw and cut from the inside out. Once I did that, the rest was easy.

I had read what previous posts I would find, and did not know whether sawing through with a hacksaw was necessary or whether it was fairly easy to pop it out with screwdriver and hammer. Got the bushings yesterday and a colleague is bringing in his "collection" (what do you want, large, medium, small or miniature he asked me) of hacksaws to choose from today, so I should have it on tommorow. <p>

My bushing was stubborn and I started to mark up the housing trying to drive/pry it out. The hacksaw was key. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

Re: Attention those who have changed the Large Upper Engine Mount. (awdnut)

Tonight I replaced the large upper engine mount with the Powerflex Yellow bushing, and installed the strut bar bushing kit as well (purple bushings. <p>I have to say that the hacksaw was definitely key. It took longer to undo the hacksaw and set it up than it did to saw it and remove it. Thanks to all who suggested it. <p>It only took an hour, and that was about 15 minutes longer than necessary as after I re-mounted the bar and had everything loosely tightened, I took the bar back off as I wanted to make sure the strut bar bushings were snug and it's VERY hard to get a wrench on the bottom bolts when the bar is on. <p>I have to say that I was surprised how much more vibration makes it's way into the car. I was expecting more, but it's quite a bit more. I've been told that the Yellow bushing is equiviant to the Evolve Black bushing. Is that true? And it's not only at idle, but throughout the rev range as well while cruising. And it is definitely louder, more of a buzzing harmonic in the cabin. Hmm, I hope I didn't go too far with this one. I suppose I'll get used to it. Hope so. <p>In any event, it makes a definite difference, even on the stock springs. Car definitely feels tighter, and doesn't feel like it's rattling quite so much over the bumps. There's definitely more road feel through the wheel as well. The car responds much more sharply. <p>I should mention that the stock bushing was starting to fail. The vertical piece that is the main beef of the mount had a crack on the lower edge that was spreading into the rubber support. It was pretty noticable when I looked at it in the bright light, even on the car. The car only has 37k miles, too. I would definitely urge all of you '04 owners with stock mounts to check this bushing.

I would suspect the purple strut bar bushings you installed are part of the vibration problem.<p>The black evolve was supposed to be tolerable with the GT tranny, but you probably pushed it well over the edge with the purple bushings. They really stiffen up the bar.

It gets much better after a couple of thousand miles.<br>First time I started it up I said to myself, "what did I do" and was this worth the trade off,<B> it is.</B> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <br>The vibration <B>is</B> more, especially on start up and in cold weather, but I don't even think about it anymore as the initial harshness smoothes out as the bushings get settled in and wear a bit.<br>You'll be fine

Some report the clutch pedal seems better too, presumably because the cables don't move as much. (edit - shift cables, that is - more precise)<p>Tom.

However, the shifts do seem smoother. I'm sure tying the whole powertrain down a little tighter is a bonus even to a GT. Clutch or no clutch, there's still shift shock. <p>But engine movement is DEFINITELY reduced. When I would drive sloppy before <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> and sharply let off the gas, there would be a definite response from the engine bay. That is gone. Of course, as I said the stock bushing was starting to fail, but the new one is definitely more rigid. <p>As much as the bushings make the engine stab. bar into more of a strut bar, it still is movable by hand. The VST bar must make the car nice and stiff.

GT - yes, I'd expect the same "punch" effect. Think of the entire engine/trans which is bearing on the lower mounts for their counterhold. The upper bar completes the triangle: front mount - rear mount - top mount.<p>Tom.

It is still VERY noticable. Did a 225 mile round trip to pick up the wife in CT today and the vibration was noticable. The vibration isn't too bad, but on the highway, part throttle gives a somewhat nasty resonance now that the resonator is gone. <p>Hope you're right Jim! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> <p>But boy does it feel better.

Re: Attention those who have changed the Large Upper Engine Mount. (needsdecaf)

I've said this before, while it does get better I do NOT like the harder bushings on an automatic, you will always have SOME vibration at idle as you have no neutral, (unless you kick it in manually at every light).<br>I put an IPD bushing on my 850R auto, it was off in a wee and a new stock one installed!
