E36 Scrape/Squealing sound when coasting in gear
-
I like have all 4 wheels off the ground anytime I work on the car for clearance and safety. With all 4 off the ground I can give the car a SOLID hip check and it won't move. If you are only going to lift the back I would put a chock front and back of at least one wheel. That's how I have done it and I have never had an issue.

I would recommend a pair of 6 ton stands, the footprint is much larger and more stable then the smaller 3 ton stands, I have 2x 6 ton stands and use 2x 3 ton stands so it is more stable when yanking on wrenches etc underneath. They can be gotten at for not much more cost and saving a few bucks won't matter much if a car falls on you.

Use them in pairs on an end of the car, ie 6ton in back and 3 ton in front. My 6 ton are about the same height at the shortest setting as the 3 ton on their longest height, so I usually have the 6 ton at the lowest or one notch up and the 3 ton extended most of the way.

Hey jc,
I tried working with those jacks today, and it was the first time the car almost fell
Luckily I wasn't under it, since I was in the process of jacking it up... is there a strategy around putting the car on 4 jacks? We were doing my girlfriend's mazda, so maybe we just didn't have the jacks in a good place -- when you have the first jacks in place and you start jacking up the other side, what stops the car from making the other jacks start to tilt?I think part of it may be us not having the jacks in the right place, so maybe when I do it on my e36 and have them in the designated spots, it won't be as much an issue.

I always lift one end at a time, not side to side, such as get the front up on the 3ton stands at a short setting, then go to the back and get it up on the 6 ton, then go back to the front and lift it to a higher setting, I have 4 wooden ramps that are really helpful, without them it is hard to get the jack under the dif or front subframe unless you have a nice low profile jack. I would recommend as much bevel on the leading edge of the steps as you can get, mine take a little practice to drive up the "steps".
And ALWAYS try to shake the car around when it is on the stands to be sure it is stable before going underneath.
Here is a side shot to show how they are constructed, the top board is 2' the second is 3' and the bottom is 4'. On 2 of them I added a block at the front edge as a stop. The great thing is that unless your car is really low even if you drove off of the front it wouldn't hurt anything.
And they all stack up nicely when you aren't using them.

Along with what has been said, I will usually stack up a wheel or two under the car in a place that wont interfere with my work if im going to be underneath it. I will also have the jack in position on the lifting point (not supporting the weight of the car at all) ready to be lifted as an extra precaution incase a helper or someone nearby needs to come to the rescue.
The biggest mistake I tend to make involves the rear wheels on the ground, car in gear, and me loosening the driveshaft, axles, or any other powertrain component which then propels the car forward making it want to come off the jack stands.
dont do that.

Luckily I do have a low profile jack, but because of that the range isn't the best. Can I get some extra range out of the jack by jacking up, for example, the front, putting on stands... then place the floor jack on some pieces of wood and jacking it farther, adjusting the jack stands again.
Also, never jacked up the rear on my car. Should I put the floor jack under the rear differential?

http://www.amazon.com/gp/product/B00BMPFI6I/ref=oh_details_o08_s02_i00?ie=UTF8&psc=1 is the jack that i have.
Is there anything that would be safe to put the jack on to get a little extra height out of it?

Rofl. Im guessing you were about to post something offensive. Such as the N-word or nudes?

Like the prostitute says: 'It's not the work. It's the stairs.'
