i got every thing ready to go on dropping my engine out. but the front two bolts (the two under the doors) i got the nuts off on both side. the bolt will turn a 1/2 a turn and the rubber mount mount turns with the bolt. and ideas on on how to get the two bolts out.
thank you for your help and time

The bolts are seized to the bushings sleeves. Happens all the time and there are tons of threads covering this. You should try a search, but the most common methods are to:

-soak them with PB Blaster/WD40, and go at it with an impact arench after a few days; or
-cut the bolt head and shaft off then counter sink the remaining portion of the bolt so it clears the ears of the chassis; or
-use a sawzall and try to cut the bolt on the inside of the chassis mounting ears; or
-use a big hammer or air chisel and work at them until they come loose.

use jacks to level out the bolt and the hole, IE no weight on the bolt. then a hammer.
I'm so glad they don't rust out here

There is one more method, I had to resort to on the front lower control arm bolts of my '85 300ZX: Borrow a ball joint tool from O'Reilleys auto parts.

Quite clearly you haven't had to deal with bolts severly rusted in the sleeve. I have beat on them with a sledge hammer, hit them with a air chisel, tried to force them out with a huge C clamp and sockets till I twisted the C-Clamp itself and then finally cut them off. I retain the scars of hitting the cutting wheel against the back of my hand at least 10 years later. I ended up putting a 6" cutting wheel in my 4" cut off tool to get enough depth to cut all the way through the sleve and bolt. No hospital run or anything. The cuts did't even bleed. But after washing my hands it was clear my skin was no longer normal. I guess it cautherized the wound as it made it. Good thing it didn't get deep enough to get the vein.

I can't recommend using a 6" cutting wheel with the guard removed like I did.

Quite clearly you have no idea what I do all day long.

I have always had good luck with an air chisel to break them loose......So far....

I agree with the air chissel crowd. Somethings got to give. As long as theres electricity to keep the compressor going you got a chance.
Once you start don't give up!!
Organize a "Tag Team" if you have to. She'll come eventually.

If they are stuck we just cut the bolts with a carbide wheel, then knock out the rubber center and replace the bushing with poly. It can take hours to try and disloge the front cradle bolts, minutes to do it this way.

If the only thing I had to deal with was the weight of the car any of the above mentioned ways would have easily pushed the bolt out.

Some grease on a fresh metal sawzall blade makes very quick work of the front cradle. Cut between the "ears" coming off the body and the cradle, they dont last more than a minute or 2. 4 cuts and less than 10 minutes later, you are done without "getting lucky" and having the bolts come free of the sleeves inside.

I have tried every thing listed above and no lock. i searched and searched with no lock. i cant get this bolts out have tried over 3 weeks. even tried a torch and ideas. going to try and get a 4 or 6in cut off wheel and try that again. nothing is cutting the sleeve.
thank you

Could you cut the cradle? I thinking about buying a new cradle, and mounting the new motor on it.. before pulling the old one

After you get the sleeve cut into and the bolt 3/4 cut then you can twist or hammer the head and break it off.

i got the bolts out i grind them out with my dermal tool. i started lifting the car with two hyd jacks. the cradle is lifting on the pas side as i lift the car. i do not now if the cradle is rocking back or if there is something hold it to the frame i have the shock bolts and the cradle bolts out.
thank you for the help.

So put the tire iron into the front joint and pry it down. How much bolt is still catching on the the hanger?

i just went thru this last week my passenger side was completely stuck in there! i actually had to cut the mounting tab off. so ya i tried everything vise grips and crow bars but in the end :-(

The front inside mounting tab is just a piece of sheet metal A screwdriver would have it bent back from the bushing if the head was cut off.

i got mine out last wk with just a impact. car was supported on my lift and cradle was supported with my steel engine cart on steel/ball bearing casters. worked like a charm. but my bolts were not seized either... good luck.

i wish it was that easy i had a long crow bar on that thing and it was like rusted to the tab i had to cut the whole inner tab off but oh well its out now, all i gota do is weld it back in.

i cut the bolt down to where it was just passed the outer surface of the ear. so it was in the ear about 1/32" in the ear the i moved the cradle around until it released it.

thank you every body will work on it more later

Cool cool cool.

Here are my 10 year old scars from putting a 6" wheel on a 4" cut off tool.

Cradle bolts, a blood sport.

I have yet to do mine, hopefully they come loose on the first try. Planning on doing the job this winter and sure appreciate the advice about the front bolts. I'm sure the rears are just as exciting!

We were so poor we had to do scars when we were kids. Now all the young people do tattoos instead.

I also had the painful experience of getting these out. I used a 1/4 drill bit and elec. drill to drill into the rubber. This would grab and jerk my hands around. It took 2 evenings to get these out and I have torches, air chisel, etc. I did not try cutting the bolts at all. Eventually enough rubber is removed to get the bushing out.
Good luck.

I got the engine out today. thanks to the help from every oe here and my pastor. now the fun begins.
happy new year to all.

I am three bolts away from that utopia .... I'm about to take an air chisel to the front bolt 8-)
