Front engine mount removal??
My front engine mount is bad, the car shakes like crazy sometimes at speeds of 75 plus, and then at times when i hit the gas, I can feel it jump up. Ive never done mounts before, But i have been reading the other forums to know to loosen the bolts then support the engine. I was gonna get a replacement from the junkyard and fill it with window weld. How long does it take to dry if I do this method? I believe one of my tranny mounts are bad also. But I dont know which one, and I cant remember if there are 2 or three tranny mounts, there were alot of tranny mounts at the junkyard, so i can get those easily, its just most of the front engine mounts were still attached to the most of the engines. Any suggestions are greatly appreciated.

thanks for the advice, i thought they said the ones from autozone were useless, but if rock auto has them then ill get them from there. My mechanic said he would only charge me $40 for the front mount install.

I had a new but cheap mount on my max vs the other 3 being OEM and better brand and still ended up getting all torn up so I burned it up and filled it completely with window weld and so far its been a week and it feels great, shouldn't be much different just reinforcing some cheap ones. Maybe someone can chime in on that

i f you wana save money, just lift the motor up a little, take the 2 bolts out of the mounts to the engine, the 4 cross meber bolts, and drop down your mounts and fill um with window weld. it helps a lot. id suggest doin the tranny mounts after the engine mounts are back in. i did mine at the same time and the whole moter and tranny shifted. it sucked going together. and theres 2 tranny mounts.

Every single one of my OEM mounts were completely busted (to the extent that they were all in pieces). Nonetheless, I just repaired/filled them all with urethane
Anyway, you'll still need to drop the crossmember, if not completely you'll still have to loosen the rear bolts/nuts so the front can dip down to give you room.
Support the engine under the oil pan with a block of wood, yes. Although ideally you don't want to be working UNDER there with just a jack. Use a jackstand if possible. Otherwise if you must use just a jack, try to offset yourself some (i.e., keep your body out from under it, so if it drops it just crushes/mutilates your hands/arms )

lol yeah im going to use 2 jack stands to support both sides of the car, cant afford to loose any part of me lol. Is it a simple repair/ replacement? Im just wondering because it looks complicated.

I have tried filling motor mounts, as well as melting out the oem rubber and replacing it with window weld, and many different polyurethanes. The best design by far (as far as holding up to abuse without creating any additional vibration at all and preventing the large amount of engine movement allowed by stock motor mounts) that I have come up with is creating a larger center pin and filling the 1/2" gap left with polyurethane. I don't have a picture of a completed one handy but here is a picture of one before filling.

Its not just washers welded to either side of the pin, those are caps to the larger pipe that makes the overall diameter of the center pin much larger. Since so much less rubber is used, there is much less possible movement and that makes a massive difference it movement. The result is virtually no torque steer, wheel hop or engine movement. Removing the trans with these mounts doesn't require bracing the engine as these prevent the motor from leaning to either side. Here is a picture of the center pin by itself.

Yeah these after market motor mounts from autozone are Doo-Doo!! I just returned the front one after only 6 months and barely driving her for 4 of those months. Does anybody know if there's a thread in here showing pics/directions of them filling there motor mounts with polyurethane or whatever else seems to be working??

Heres the link to how to do it. This is the one I followed and the same stuff I used.

How long would you guys say the 3M window weld (I take it this is the same stuff you refer to as poly) can stay in service before it would need to be burned out. Does it just flake off over time, and fall out?
#24
I've done 3 cars with 3M window weld and they've seen 5 years on a Tercel I filled all the Mounts on! My 3G is 3 years itself! no flaking nor peeling yet! Prep it good and it's bonded forever!
#26
Going with the window weld, it's 25 bucks (10.5 fl oz) here in Canada. Flexane is 75! and I think it's 2 component. There are 2 others available in the same price range, scotch weld or Loctite. I'll go with the one you guys have tested - 3M.
