My front motor mount is absolutely shredded. I know that I have to support the engine, break loose the nut on the side, then take loose the 2 on the crossmember. And I also know that some people recommend dropping the whole crossmember, but I already tried that.. My car has 303,xxx miles on it and I could not get a SINGLE ONE of the bolts loose on the motor mounts. And if I managed to get any movement, it was only spinning on both ends. It's pretty impossible to get leverage on the mounts, and I'm just wondering if there's some tricks to it or if I'm just going to have to stop by and use a shop's high-powered air tools to take off a little bolt... Thanks in advance.

edit: I have tried breaker bars with a 4' cheater and an electric impact wrench. Next step is a friend's super heavy duty impact wrench.. (took off the crank pulley in under a second). Just looking for some insight.

 

Saturate the nut and threads with a good penetrant like kroil or pb blaster, let it sit overnight, next day spray a little more then immediately put your breaker on it again but may help to whack the breaker a few times with a 5-10lb sledge.

 

Impact gun, game over...

 

Amen

 

I got it with a pb blaster,rubber mallet and a hand wrench. Took some swings and nut broke loose.

 

I'll try the pb blaster and sledge first. It's hard for a broke boy like me to get my hands on a stromg enough impact wrench. Thanks y'all i'll update with the results. Anyone else feel free to chime in. Unless you're a "'search' *****". Lol

 

This is ghetto and potentially dangerous.

Soaked them in PBlaster. Using a ratchet and socket I took my floor jack and pumped up the far end of the handle of my ratchet. I had to make sure that I lined it up at a good angle so pushing upward would be loosening, obviously. If you got poor quality tools or sockets they may break, I broke a cheap "crows foot" attachment. I used extra jack stands and jack, you want to make sure that jacking it up isn't moving the whole vehicle, which could be dangerous.

Obviously this isn't the ideal process but, it worked
:P

 

Only problem with that is that my leverage is at a terrible angle.. Idk if that would do anything for me except strip the nut or break my bar.. lol i already bought tools to do this with (and not the cheap crap) but those puppies are TIGHT.

 

Dewalt impact gun. You'll be happy you bought it.

 

dewalt electric impact? i have an electric one that's rated for 330 ft/lbs but it doesn't do anything.

 

Wow that should've got the job done. Spray with pblaster I guess.

 

Nothing worked. I fixed it VERY temporarily by just snaking a tube in and doing window-weld injections into the front and back mounts. I'll have to just use a heavy duty impact in a week or two I guess. Now to wait until it cures -___-
