Alright I'll try and break it down for you on whether you should use ramps or not using this simple test:
>Does the vehicle need to be raised off of the ground in order to do the work needed?
If no, perform work.
If yes, continue to next question.
>Do you need to remove the wheels from the vehicle in order to perform the work?
If yes, use jack.
If no, use ramps.

There you go!

Nobody is stupid enough to think that's a problem but you.

>any reason to use these over a jack?
Those types of machine bent ramps are not recommended. They are examples of unbraced (no additional support for the bent sections). They are subject to unpredictable failure if the car is rocked from side to side.

>>16408689
>Only worries of degradation of polymer / plastic material.
While race ramps are fairly solid foam, they can degrade if a tire runs along the edge or against the end lip.

>Rhino Ramps
They are pretty good despite scaring some people with how hollow they are. You should inspect them before use. Their weakness is running the car too far forward on the ramps which will cause stress cracks inside the plastic. That's because with the car so forward, the weight is no longer distributed evenly. To oversimplify, as a tire rests on the ground, imagine a pyramid with its top tip where the tire rests upon the ground. That pyramid represents how the stress from the weight is distributed downwards. As you look at it from a side view you see a nice even slope on the front and back. Nice even force distribution. Now, imagine the ground ends at a sharp vertical cliff. As the tire rolls forward to the very edge of that cliff, that nice triangular stress distribution ceases because the cliff is now blocking off force distribution. That very uneven force distribution causes the plastic at that end zone area to have microstress cracks you cannot see. Over time and repeated drivings, it can get to the point of sudden failure. So, never drive anywhere near the end of a rhino or other plastic ramp now that you visualized this stress model.

if the weight of a car is pushing on a jack stand in the direction if the red arrow, why doesn't a jack stand slip out from under the car?

File: 4[1].jpg (18KB, 400x400px) Image search: [Google]

18KB, 400x400px

I use these

>>16409352
if that was the direction weight was pushing, you would be right. but the direction is more or less straight down. especially if you block the back wheels

>>16409352
friction and there is barely any sideways force. it's 99% straight down. your red arrow is uneducated conjecture.

>>16409352
Cause the weight of the car isn't pushing from that direction

>>16409352
Because you are oversimplifying the problem. YOU considered the jack stand to be a single rod with one end touching the car and the other end touching the floor. Jack stands now have pyramid bases (four points) and not triangular (three points) touching the floor. That along with the the fact you set the parking brake holds the car there. Of course, if your parking brake is off, then the car could fall off the jack stand.

Some people do put roll over ramps under the rear wheels. That not only adds a lot more space under the car where a body can fit, but also levels the car more to reduce the chance it rolls off the stand.

Yeah because a straight piece of metal with a metal rod inserted into it is such a fragile structure.

If you are so afraid of jack stands failing, I don't understand how you can think ramps can't do the same.
The result is always the same, your car goes down and you die

It's more being worried about the jackstands tipping than breaking.

>>16412405
Some cars you may have to pull the halfshafts to drop the transmission to get to the clutch.

So you can't even do some driveline work with ramps.

>>16412445
That's why you always put the wheel/tire under the car if you're afraid of that.

If you're on a level hard surface, and have put the car on the stands correctly, they should never tip.

You can drive your car up a wooden ramp you make yourself from cheap plywood that has 3 inches height. Or you can fill plastic grocery bags with sand and stack them up to form a low ramp. Drive up that and you have enough height for your jack.

If you don't have ramps, for inspection, you can use a selfie stick to remotely take pictures. Might as well make that powerful camera work for you. Of course, don't do it when the engine is hot because heat can melt something if you accidentally lean the camera on something hot.

>>16438479
>why wouldn't using four ramps not be a viable solution?
Because if you have a jack, you can lift up the car and push a solid wooden platform under each of the rear tires. That's because if those rear ramps aren't rollover ramps, you basically have to push new ramps under the car for the rear wheels just before the front wheels go up their ramps. That's just too much trouble and preciseness required.

>Wood blocks are superior.
Instead of ramps, I like to jack the car up and put a wide wood block under it. It can be tall and wide so there is enough room under the car for a bucket to catch the oil.

The blocks are wide enough to not fall over, tip over, or have the tires close to any edge. So it is impossible for the type of accident where you have an object up on stilts and it falls over when there is a large sideways force.

To protect individual pieces of lumber making up the block, the top of each block is finished with a single piece of plywood. That makes sure that the tire can't just exert force on individual pieces of wood in the block and make them move around.

>why wouldn't using four ramps not be a viable solution?
The long ramps get in the way of sliding under the car.

triggered used to repairs on my first like that till it collapsed mid tire change on my buddies car.

>At least the kid would probably be OK
The problem is if the kid accidentally touches the jack. If he slips while moving around, kids tend to just mindlessly grab at something especially since the jack and its handles are next to him.

>>16438479
>why wouldn't using four ramps not be a viable solution?
4 ramps equals more precision driving needed and if you fall off the ramps, you damage the car. So when you use 4 ramps, you greatly increase the risk of accident.

Thousand pounds on a cinderblock isn't very safe.

>>16449397
Cinderblocks are susceptible to the domino effect of crumbling. As soon as one small portion cinder section starts to crumble, the added stress to adjacent portions starts them to crumble too. Pretty soon you have a giant cascade effect of crumbling in these airy cinder blocks.

This. Whoever thought of a cinder block as a safe alternative to an axle stand must have been dropped on a cinder block at birth.

I want to see what kind of jack she uses.

i have never had a jack fail on me ever in my life

i have even used a jack with one of the wheels falling off and it never failed


i have never known anyone who had a jack fail or were hurt by it

if you use jack stands and a jack like you are soposed to there should be no issue

>>16429767
Bonus: after you use those jacks once the paint on the metall cracks und the whole piece crumbles away in the next winter

>>16451972
It's scary that the car isn't jacked up enough to remove the tire but the jack is already bending under the load. I suppose all those people who say that they never had a jack fail would then get under the car to work on it. But I would be too worried the jack would give way while I was even pulling the wheel off the car. Just that extra motion might make the jack collapse. The car would crash down on the rotor and damage various parts.

dude fucking this. I set a jack stand just to get under the car to loosen the oil sump bolt

>The car would crash down on the rotor and damage various parts.

Surprisingly, having the rotor smack into the ground doesn't actually cause all that much damage. A flat spot on the rotor maybe, a slight bur on the outside of the rotor if it happens at speed, possibly causing issues with brake pad wear if it's bad enough, a bent dust shield if it has one, and that's about it. From a great enough height, it might shear some lugs off, but that's pretty unlikely. Hitting a pothole at 80 MPH likely has the same amount of force, if not more, than dropping a car off a jack from a height of 18 inches.

I actually knew a person who lost a wheel while going down the road in an old Bronco. They put the tire back on and drove away, only damage was a bent dust shield. Kind of surprising really, you'd expect it to do more.

>>16453197
Still, a warped rotor means wiggly brakes as can be felt on the brake pedal. I guess that means buying a new rotor is the only solution since the other side is also wavy.


Each time they turn the rotor, it seems there is only one turn and it is time for a new one. I remember in the old days the dealer (a different one) would allow up to 3 turnings on my brakes. But now, maybe they are scamming me on turnings.

>any reason to use these over a jack?
I'll just make some wooden blocks and jack the car up onto those. The car will settle some, so I'll have to make the blocks taller, so that's the sucky part. I'll buy some jack stands at harbor freight and use those as the insurance.

It's only a little bit scary relying on the emergency brake to stop the car from moving. I'm mostly depending on the transmission being set to Park to hold the car still.

>>16408203
Gee Bill.

Here's the kicker.
The design has not changed in over 40 years. That is only for replacing the spare tire, not under-body work.

>>16456649
Crumple Zones are good.
That is why we also built a crumple zone into the jack.

>>16456649
The design should have changed to be more robust due to the weight of the car. It does look pretty thin to be a jack.

Oh boy, you guys haven't seen the ORIGINAL VW jack before then, circa 1930.

A beautiful bit of engineering, it uses the weight of the car to twist a ring on the smooth shaft, locking it in place. You move the lever down, locking the 2nd against the shaft, levering the car upwards, and sliding a 1st ring up the shaft. Moving the lever back up transfers the weight down onto the 1st ring again. Repeat.

Really good bit of design, really lightweight and compact, and very cheap to make when compared to a scissor jack. Potentially limitless range too. They locked into the side of the car with a square socket, stopping them falling over. Great for changing wheels.
