Re: Jack stands?

four stands of appropriate capacity should be sufficient..

I do recommend this style Shop for cross pin jack stands

cross pins are much more secure than ratchet pawl type, especially for rigorous work on the vehicle..

wider stance stands are much more stable for long term work..

they're also available in various heights for taller working positions..

you can stagger you lifting heights from front to rear to work your way up to taller heights if all you have is a floor jack..

keep adding wood blocks to the jack as you incrementally raise the stands or even switch to taller stands if necessary..

good tools like these will last a lifetime.. buy once, cry once

good luck!

From my experience you pretty well have to start off with four jack stands, two in front and two at the rear. This is because the adjustment for common stands is limited, while the frame is uneven. Then sneak some in the middle someplace after the frame is lifted. Just adjust those, by sliding them front or back until you find a spot.

Be sure to pull the middle jacks out of the way before you lower the truck (gulp!). They're only there for just in case.

Nothing wrong with adding a block or two, and/or added support with floor jacks. If that's an entire truck on jack stands, imagine how it would feel to crash down on you IMO, four jack stands isn't enough.

My frame is bare less an engine and trans. It's currently supported by two stands at the rear, two stands near the front leaf spring mounts. Blocks I made for the engine cross member, an engine hoist and transmission jack............. Getting ready to pull the engine. Before that disaster, the frame was supported by four sets of jack stands...... Better to error on the side of caution.

I'd raise and lower the front and back a little at a time. Last thing you need is a jack stand slipping on you.





Nice stands Killer Bee. In hindsight I'd have picked those up, but I ended up with various sizes of these. https://www.northerntool.com/shop/to...1758_200641758

Re: Jack stands?

Thanks for all the great advice - safety must be a top priority.

While I don't plan on pulling the engine / trans, (yet) I do have a good bit of suspension work to do. IE springs and shocks front and rear, ball joints etc. Lots of hammering, pushing and pulling once it warms up a bit.

Once you have it up in the air where you want it,stand back and shake the crap out of it to see if it will give!

Thatís what I do!
Plus I put my floor jack under the end Iím working on. Slight pressure on the engine cradle or on the rear end.
Wood works too. Three new big tree stumps work good. Two close to the outside on the rear end and one under the engine cradle.

Re: Jack stands?

The weight rating in tons is for the pair of stands. I like ratcheting stands. Get two good pair of stands.

You just need to use common sense. And that includes when you are under the vehicle. For example, would you work with the vehicle jacked up and your head directly under the axle pumpkin? I hope 'NO' is the answer. Just be conscientious of where your body is laying when you start yanking on bolts with big breaker bars or pounding with a double jack!

This is sound advice. I always advise this when helping someone repair their own vehicle (loaning tools/equipment so they can do it).

One buddy commented "if you shake it hard enough, it will fall". I told him no it won't if done correctly. He jacked his car up to work on it (brakes). He put the jack stands under it. He got out & did the shake test...... It fell off the stands. He called me & was freaked out! I stopped by & went over what he did. He didn't place the stands in a solid/flat spot (put them on a poor section of frame).

Needless to say he was glad I passed the testing idea along. He also just paid me to do the work. He was done w/the idea of getting under a vehicle.

Re: Jack stands?

Not the best pic, but I use these cribbing stands.

Mine are build with 2x4's and are 12"x14" wide. I have a pair that raises the vehicle 6" and this set raises the car 9".

In this photo I've actually been under the car removing an transmission to convert to a manual trans.

I prefer these to jack stands!

Re: Jack stands?

The cribbing looks great; however I need to have all 4 wheels off so frame jack stands and safety cribbing appears to be the best options.

Re: Jack stands?

All my jack stands are the professional type with cogged/rachet design which are as safe and strong as any jack stand made. One thing to consider when buying stands is size/bulk. That is the advantage of buying the specific tool for the job compared to building wood cribbing or other means to hold truck up. What you use to hold the truck up has to be out of the way of the work you need to do.

Four jack stands are all you need to safely hold an entire vehicle in the air. Adding more actually takes away some safety, but mostly it's just plan uneccessary. A vehicle frame is strong enough to support the vehicle it is under. It is held off the ground by four contact points when you drive it.

I place the stands where they can "nestle", such as under an axle tube, frame rail, spring eye, etc. If frame isn't straight where stand is needed I look for a place up against something in the direction it would want to slide so there is no place to slide, like up against a spring bracket.

Most important for starters is having the jack stand planted level and stable on the ground before putting any weight on it. I work off of gravel a lot, so being safety minded is extremely important. Ain't no half way nothin'! I slide and dig them in till they sit true to vertical. Just like building a house, any degree of lean from true vertical is the first step toward falling over. Watch out for ground conditions and act accordingly. The ground here can be moist and soft, dry and hard, frozen then thawed and all that can cause movement if conditions change. Be observant. Using a big wide board, like a 12" length of 2 x12 makes a great footing to spread the weight under the jack stand. I also like 3/4" plywood because it won't split. If using jack stands on asphalt it's nice to use the wood to prevent the jack stand from digging into the pavement.

Re: Jack stands?

While we are on the subject, when you are placing your truck, car, etc on 4 jack stands, make absolutely sure the jack rolls while jacking the vehicle up. Many people do not realize when using a floor jack, it has to roll with the jacking or it will pull the car off. You can test this yourself, place the front of your truck on jack stands in a good safe secure location and then jack the back of the truck up with the jack wheels restricted from rolling (shop rags work great) and proceed to jack the truck up. Watch as the jack motion will begin to pull the truck backward, pulling it off of the front jack stands. I have seen more accidents in shops because of this than any other means of supporting a vehicle in the air.

Most important to use your head and be safe.

Tom
