Re: Is it ok to lift the car up by the front bumper?

do you know anybody that has a garage or at least a concrete driveway? It is dangerous to jack up a car in the grass and get under it. Are you taking off the actual bumper? It is a piece of square tubing about 3 1/2 ft long directly behind the plastic bumper pad thing (hard to explain). I wouldn't reccommend this because if you happened to get into a front end wreck, I'm thinking you engine is going to be sitting in your lap. When you get past all the plastic bumper cover and pretty stuff, the rest of it is actually functional

Re: Is it ok to lift the car up by the front bumper?

I actually removed the crash bar from my 3000gt about 3 days before i totalling it. Lost control at 55mph becuase of a mechanical malfunction. Took out about 6 small trees only 5 inches in diameter or so and hit a ditch, became air borne, and hit a tree head on which spun my car sideways and rested the rear end in a tree. There's pics on my website. I didnt have a scratch on me, but the car was totalled. I think if i had had left the crash bar on the front, i would been hurt alot more from hitting that tree head on. It ripped two motor mounts from the block, cracked the block where the front axel connected, tore the transmission from the block and split the transmission casing in half the other away. It was a pretty bad accident but i wasnt hurt a single bit. If i had the crash bar i may have saved the engine, but i'm sure my body would have take a much worse beating.

I think i will do what Injuneer said. I'll get one of those engine hoist attachments that allow you to put a bolt through each side like on an exhaust manifold bolt, and hoist the engine out that way. I will hook it through the bumper connectors though. I have a 3/4" piece of plywood that i will set the jack and stuff on. I replaced a transmission this way, and done a billion other things. If i use jack stands i set them on old brake rotors which supports them perfect. It's safe to do it in the grass, just not very clean.

sounds like that sucked ***. Hate to hear it. Are you trying to pull the entire motor to install headers?

No i'm just hoisting the engine up from the front so i can have as much clearence as i need to install the headers. I dont feel jackstands are very safe, nor are mine long enough to reach as far as i need the front end lifted. I will have to unbolt the motors mounts im sure.

Re: Is it ok to lift the car up by the front bumper?

nothing is probably that safe in the grass, besides ramps of course. Jack stands are about the safest thing other than a lift, but there are not very many with a lift in their garage. If I had a taller ceiling i would get one. They are not very expensive.

Lifting the car by your strut tower brace is also stupid. Just because you have done it dosen't make it smart.

Have you ever worked on a car before? It's not always possible to work on our cars in a fully-equipped shop. Therefore many of us have managed to find ways to get the job done with the tools we have. My STB is made of chromemoly rollbar tubing and attached by four large studs/bolts. I would imagine that a piece of steel strong enough to protect a person in a rollover would have the strength to support the front end of a car if a chain were attached to it. As far as the engine support stand, that is a complete joke. A jack and piece of wood have served many a mechanic for decades, myself included. You have to work with what's available to you, and not all of us have the luxury of owning specialized equipment and a lift.

Re: Is it ok to lift the car up by the front bumper?

When I jack up the front of the car, where do I put the jack stands? I need to change my oil!

I've worked on cars for the last 25 years. So yeah, you could say I have a bit of experience in the area. I don't have a lift at my disposal, but I do have a garage with a concrete floor. No matter what your resorces, there is always a safe way to get things done. I would never jack a car on grass and then get under it, it's an accident in the making.

Shawn, I live a few miles from you. Shoot me a PM if you get in a jam and need help.

Re: Is it ok to lift the car up by the front bumper?

i don't know if this helps (or if it was already posted) but i just got through a couple of engine removals using a chain fall hung from our garage beams (it was custom built i wouldn't reccomend it if your garage was built by kb homes or something). We followed this method step by step basically:

I put my jack stands under the K member. Don't waste your time or money on them though. Go to Wal-mart and buy some Rhino ramps and just drive the front onto them. They give you plenty enough clearence to change your oil.

Re: Is it ok to lift the car up by the front bumper?

You have got to be kidding me. You are going first lift by the bumper reinforcement and then remove it. What are you thinking. That re-inforcement is ment to be hit front the front, not from under. If you only mess up the reinforcement you will be lucky, hopefully you don't pull rails with it too. Stop the getto rigging, the weight you save on the reinforcement will be nothing for a street driven car. I would STRONGLY recomend that you DO NOT remove the re-inforcement. GM put it there for a reason, LEAVE IT.

Clearly, if the front bumper support was missing, this young man would be dead.

I'm not sure what I think about the front support. I have to admit that removing it is stupid, but I think a boxed-tubing lightweight replacement would hold up juuuuust fine. Remember, NASCAR cars are built of nothing but rollcage material, and they can be thrown in the air without collapsing. No reason that a carefully made support TIG welded together couldn't do the job of the stocker just as well.

A NASCAR race cars frame and roll bars are made of high quality cromemolly tubing. This stuff is super strong and better than 9 out of 10 roll bars are made of. Bad comparrison there.
