Lets not forget these bags either !

Bags are for vac. cleaners!

 

Not that this thread is heading anywhere productive but the only steps I left out are deflating the tire and squeezing it out of the wheel well. In my mind I was explaining it as if you had a flat tire so it would already be "squeezed". You did specify that it was for a tire rotation so I am in the wrong for leaving it out.

As far as what you consider confusing or complicated he explained it even more simply than I did and you asked for a set of instructions that even a child could follow.

Honestly any child big enough to do the work could probably understand his directions.

I guess we could round one up and see what happens?

 

Before you pop off again and look even sillier, go back to where you interjected your salted opinion and actually read what you quoted and posted to, and that would be my question that you didn't answer.

If it's that's easy for a child to actually perform the procedure perhaps it's to much for a childish adult to write it up. The child realizes he's a child.

It's quite apparent that the reading comprehension is not one of the better qualities being displayed.

​

 

He said how he changes the tires on his Buick.

You quoted him saying this and asked how you would explain this to someone doing a tire rotation.

I asked how he could explain it any simpler.

What am I missing.

Seriously, I'm actually curious at this point.

 

Wait wait wait

Are you referring the very end where he says that the original poster will most likely figure out a way to do it that isn't super complicated?

In that case yes I completely missed what you were talking about and my comments don't even address what you were talking about.

If I got that right then sure I guess it's likely that the original poster is just as likely to figure out a complicated way to do it that a child couldn't figure out.

 

If the tires are worn out it's time to sell the car.

 

I have a guess or two "why" you're missing it but I'll try to get you to see what you're missing and quell the curiosity.

Seriously comprehension isn't a strong point for you is it. It's pretty thick so I'll help you thru it. You'll have to read it though and I see that's difficult so I'll type real slow.

Here I asked "inked monkey" to explain the procedure to me for a tire rotation on my rack.


Here's you jumping in trying to be funny about non related stuff but completely ignoring the request to explain the procedure for a tire rotation on a rack.



Now here I tell you it's funny, and since you jumped in with plenty of sarcasm to explain the procedure. On a rack for tire rotation. Read it slow because I typed this one really fast.

Your next posts basically repeated inked monkey but included your snide remarks about me being able to understand the simplest things. Now since I said "so a child could follow" I guess I asked for most of that. But I gotta tell you if I was 10 or 12 and you talked like that to me I'd kick you square in the nuts.

I didn't think it would be this hard for you to out line the procedure since you jumped in and all. However you haven't tried that yet, you can't even follow what going on here. I may have given too much credit where none was due and that's my fault.

So in the spirit of "A Christmas story"
I triple dog dare you!!



Merry Christmas Tim,
don't let me down

 

Got cubic dollars? Get four of those frame-mounted, pneumatic jacks all the modern sports prototype and Indy cars have! LOL. Gary

 

Yup I totally glazed over doing it on a rack/ lift. You've got me there. Right in the open and very specific

 

If I were to guess how to go about it, I'm assuming your rack is like a two post lift that lets all the wheels hang, I'd pick the car up and then either put it in a position to use a human to lift the opposite side tire or if you have a lift you might also have a transmission jack that you'd use to pull a transmission out from
Under the car. You might be able to use something like that to lift the tire.

I agree it does sound convoluted. I'll fall on that sword

 

Ok fair enough Tim - but I'd like to point out that you did catch the "rack" component perfectly clear at least once and went off on a diatribe about it.

It's very clear you don't know how to work on this shit and your guessing just tossed the car nose first off the lift.

The tire rotation process for that Buick mentioned by inked monkey goes like this !

Air the suspension up.
Drive in and Position the lift arms.
Raise car 12-18" off the ground
Position small jack stands under rear axle
Position small jack stands under front suspension.
Lower vehicle on the stands
Release air from the suspension.
Raise vehicle to working height
Remove Schrader valves from rear tires
Remove front tires and balance them.
Remove Schrader valves from front tires
(Most places have 2 safety stands this job takes 4)
Place 2 safety stands on frame At front of vehicle
Place 1 safety stand on rear frame rail
Place 1 safety stand under rear axle near tire and lift one side of rear axle enough to remove opposite side tire.
Remove low side rear tire
Install balanced tire from front on the low side rear rear
Lower safety stand on axle and position under frame.
Lower safety stand on opposite side frame and position under axle
Lift that other side of rear axle
Remove low side rear tire
Install balanced tire from the front
Lower safety stand under axle and remove
Remove 3 remaining safety stands
Install shaders at rear and set desired tire pressure
Install shaders in tires removed from rear & set desired pressure
Balance those tires
Install front tires
Tighten lug nuts
Lower the car to 12-18" from ground
Position jack stands under rear axle and front suspension
Lower car onto jack stands
Air up suspension more than enough to a avoid damage from rack arms.
Raise vehicle
Remove jack stands
Lower vehicle
Stow lift arms
Drive car out of lift.

That's for a rotation, but the process would be the same for rear brake jobs, or vacation / road trip tire repairs. About a $400 bill for that and Airbag Andy blows a gasket "400 bucks for a tire rotation?!?". Refer to my earlier post about appreciated engineering and fab work but being easily repulsed. Ignoring the very basics like removable wheels and tires is not cool. Cars that ride like shit ain't cool.

Any successful designer will tell you that form follows function. What that means is function leads and form follows. What that means is functionality is first and form or looks is secondary.

 

Ok, all together now...deck my balls with boughs of holly, falla, lala laaa.......

 

Who's on first?

 

Says the guy with 27 posts.

 

I didn't realize that this was going to be such a big deal especially for people who "don't get it" and don't do it. I guess next time I post something, I'll clarify that I'm only talking to the people that it pertains to or that will at least be constructive.

I just didn't see the need to attack someone that participated in the thread. I suppose it makes weak folks feel strong. That's something that I don't get.

 

GM airbag usage went back to prewar on buses and trucks.
The 57 Eldorado Brougham was the first production car with airbags. They used an electric pump and complex solenoids and valves to self level. It was trouble prone and the majority of cars have been converted to springs. I have done a couple of reliable conversions to a modern bag retaining full factory spec suspension travel.
I also owned a 59 Biarritz with bags which used a belt driven pump and a less complex self leveling valve setup. I converted it also.
The Cads have a Lift lever which pressurised the whole system raising the car to full travel. Great for clearing bad driveways and changing tires.
The original two piece can and cup style bag was flawed and leaked from new. I updated my system, remaining on the selflevelling valves and belt driven pump but replacing the bags with modern Firestone light truck rolling sleeve bags.
The only safe way to change a tire is to get full travel in the back and you need a minimum of 9 inches of bag travel.

Convoluted bags don't come anywhere near that amount of travel.
So essentially you need a bag that will travel the full roll of suspension travel from bump stop to shocky stop. That determines your bag specs.
If you still can't change a tire with full original travel them you may need to drop the shocky, or re think the shocky length.
I really enjoyed the ride on my 59 and everyone did love when it was dropped low but I would never drive like that and may even do the front of my 39 custom on bags just because working on the front end is so easy when you can deflate the bags.

 

The rod only holds the bag from sliding when there isn't any pressure on it like when jacking it up. Strength isn't really necessary under load because the air pressure pushes it into the frame.

 

As in any group of people you will find those willing to listen and possibly offer suggestions and those who are just posting to annoy as many people as possible. Since the site has a high number of older male posters, it has an abundance of grumpy old men. Many members don't think cars should have fenders. As with all internet sites, interact with the people providing useful information and don't feed the trolls by responding to them unless you like to play with them. It can be fun at times.

 

Ain't that the truth. I have previously documented the history of pneumatic suspension going back to 1901, the invention and patent of the nearly identical to current double-convoluted air bag by Firestone, in 1938, early experiments in air ride from then, to present, installation of air suspension on military vehicles, aircraft and transport devices in WWII, as well as the early installation of air ride, many times culled from the GM take-outs, by Latino car builders in the Los Angeles basin and the Mission in San Francisco from the late 50's to present, along side and simultaneous to the origin of hydraulics (including laying frame/rocker), only to be told that there is no history of it, and that the Latino contribution to our culture doesn't count, and therefor no tradition of it.

I get it. Many of you never saw it. It does not mean that it did not exist. I cannot see atoms, molecules, viruses, bacteria, but I am pretty sure they exist, too.

I saw it. I repeated it. Others saw it and repeated it too. That is the definition of tradition, whether you like it, or not.

For those of you complaining, how many tech posts have you made? How many people have you helped? What positive contributions do you make here?

Que the millitant ignorati that are claiming that I am attempting to twist or re-write a history that they have no knowledge of themselves.

 

Thank you. You have restored my faith in humanity and this forum. I was beginning to think that I may have made a mistake joining.

Btw.. Engine Man is exactly right about the all thread. There is no load on it except when I'm changing a tire. I did shop around however, in order to find stainless steel all thread. Seems like it's doing the trick.

 

Wrong, if he can drop the bag with those threaded rods, it is because his shocks allow the axle to drop further than the bag height, they are not hooked to the top of the bag, but the frame. RRRRRiiiippppp!!!!!

 

from what i see, spinning the wing nuts up the thread is the equivalent of unbolting the top of the bag. so it won't over extend. or maybe i am looking at it wrong?

 

True, the assumption is the shocks are the positive stop, and need to be unbolted in order to drop the axle further. I agree that if the shock mounts and travel do allow the axle to drop further than the design parameters of the bag, it will tear them up.

 

What a fucking shit storm! Really? If the car is that low, should you know what previsions should be made for a flat? Who the hell builds something that has no means of repairing? Blown bags, a flat with the rim below the scrub line,or worse? Jeeze! I guess it's throw the Hail Mary pass, and hope it ends up in the right place!
Called homework! The right jack, cribbing (blocks to you freshies), and knowing WTF you are doing!
Ugghhh.

 

A,a duck order please.....a BB gun on the side.

 

Wow, I don't know where this thing went. I've never tried taking off one of the rear tires on a rack as I don't have access to one. Mine is set up with a safe scrub line even if I blow both bags and have a flat tire. My only issue was the factory half skirts.

As for the comment about the OP getting his tires off, I was meaning that he'll have to try a few different methods and decide which is best for his car.

 

This is lower than low.
