What is the best way to jack the car so that you get all 4 wheels are off the ground? Ramps are great but not for doing things like rotating tires. So what is the best way to jack up the front and rear? I've heard pro's and con's about using the diff to jack the rear of the car and not sure about the front.

And what is the best way to tell if the car is jacked up level to do things like change tranny fluilds and diff fluids?

I was going to give it my first try to jack the car today - found a thread that talked about using jack points along the "rail" (frame) that runs between the front/rear wheel wells. Also some other points that some members preferred instead. If using jack stands and a floor jack however, I would need four points to get two wheels off the ground on the same side.




Jack Point Thread

ya saw that thread but still wonder if there is something in the center because if you use those jackpoints you have to lift one side but how do you get the jack under the side your lifting.

I haven't seen it done with an RX8 yet, but Miata guys would often fit their floor jacks with a grooved 2x4 that fit the frame rail lip and offered enough weight distribution to lift the side up in the center using one jack point.

Personally, I never wanted to risk it (collapsing the frame rail lip and possibly bending the rail), so I bought a cheap set of jack stands and a small floor jack ($20 or $30 for all of it), and use all four jackpoints with jackstands. The floor jack will lift the side in just a few pumps, so I can have the car up in the air within 2 minutes or so. This is great for rotating tires, changing oil/fluids, or just looking at how Mazda put the thing together.

When I did the caliper painting over a weekend I lifted the car by each of the jack points. I did the rear first and it lifted enough to put a jack stand under the front A arm also. I put a stand under the back supension arm. Then lifted the front to adjust the jack stand higher to get the tire off. My concern was too much lean angle on one stand. It was solid when in the air. Not sure where I will put the jack stand when I install my springs, thats going to be a bitch.

The best way to jack a car here is with a gun, of course....

Used my small floor jack to jack the rear - one at a time. Wanted to put some treatment on the surface rust on the wheel hubs (only seemed to be on the rear wheels) - looking forward to painting the hubs and calipers but that's another thread. I used the "knuckle" just inside the rails on each side. My floor jack point isn't deep enough to use the rails - it would crush them first (of course the jack would have worked just fine). Actually was pretty painless although I like the idea about a slotted 2X4 - would minimize any paint scratching that may turn into corrosion later.

If you have a hydraulic floor jack of the kind where the saddle is held in by a cotter pin, Eastwood Co. sells an adapter that fits your frame rail. It's a simple U-shaped piece of steel with a shaft welded on the bottom.

I've been using one for a number of years and it lets you jack the car via the frame rails but the floor jack is much faster than the jack supplied with the car. Can also use the floor jack and Mazda scissors jack together to lift up one whole side of the car to rotate tires.

this jack any good?

That's cool- thanks for the info- I'll have to check if my cheap-o jack has a removable saddle.

G8rboy

Yep- that's a real nice one. Harbor Freight usually has some pretty good deals...

WARNING Avoid Harbor Freight when quality is important!

They have great prices but really cheap quality goods. You do not want to skimp on quality when your life could depend on it. I've found these "racer-style" jacks leak hydraulic fluid under pressure and have poor release control. They can serve a specific use (say at a track when changing one tire at a time) but otherwise I'd avoid them.

One thing that complicates the situation is I've seen similar jacks advertised that look almost identical but have different hydraulic mechanisms. Quality varies immensely but it's hard to tell just looking at it.

So what brand/model would you recommend then ?

PUR NRG

I don't know of any mail-order lightweight jacks that I can recommend. The true racing jacks are $600 or so. I do have a similar lightweight jack (of better quality) that I only use to rotate tires. If I get under the car I use different equipment.

The jack I use at home and highly recommend is the AC Hydraulik. The DK20Q ($290) is a low profile jack and the DK12HLQ ($430)the extended reach version. You can get both of them here.

Jacks and jack stands are two critical pieces where an equipment failure can result in life-threatening injuries. It's not worth the risk to use low quality stuff.

Still, the endangerment for life and limb is usually null in terms of the jack itself if all you're doing is jacking up to put some stands down. Even if for whatever reason you're placing a stand towards the middle of the vehicle where you may put your body in danger, you can observe if the jack is operating well enough to support weight before sliding under to place the stand.

Basically just making the point that following suggested practices, 99.99999999% of people get by with the $40 craftsman floor jack/jack stand set for years without incident, and for a lot of those people, spending hundreds of dollars isn't very feasible. Of course, the choice of whether or not 0.00000001% of a chance * life and/or limb is worth spending those couple hundred dollars is something everyone has to make on their own.
