Removing front crossmember - questions

[BubbaGreen]

Hey guys,
I would like to pull the front cross member out of my truck....
The engine & transmission is out, what is the easiest/safest way to accomplish this?

It is pretty much stipped down to just the
crossmember, wheels are still on at this time.
Do I need to put the motor back in to do this, the main reason, is I want to replace all the suspention components, upper/lower
shafts and ball joints. And do some cleaning
while I am at it. Thanks.

I've never done it, but I say, make sure all your brake lines are out of the way, make sure it's all disconnected, and unbolted, and roll that bad boy out!

They are simple to remove bolts on each side where upper a arms bolt to.might take some cohesion to get it out,and sometimes a pain to put back in if the frame stretches and bows a hair-so its hard to get back inside sometimes-but a come-along to pull the frame in together fixes that simply/but sometimes they fall out and slip right back in.usually if everythings reall greasy and oily they come apart easier,but if frame is dry and crusty,sometimes harder,maybe cause they rust together a bit.I certainly wouldnt put motor in thatd be pointless,and when you put it back together-use the bolts that came out of it,not some 2 cent hardware store bolt.where the hell is the cents key?????i cant find it!!!

If you're wanting to replace suspension components, I think you'll need to put the engine back in so that you've got some weight on the front end. Otherwise you've got some dangerous spring tension if you start unbolting suspension stuff. If you're just swapping front crossmembers with a later model truck, then you could just unbolt, slide out, slide new stuff in, and bolt back up with some minor hole enlarging. Just make sure you wrap a chain around the springs before doing ball joints or control arms.

BubbaGreen,
I am right about the same stage. I found an article that explains it pretty well.
You might want to check out the whole article. This link will get you to the front-end disassembly part. http://www.earlyclassic.com/ctfeb2001pg1.html

theres something like 14 bolts total holding this crossmember on. you can remove it with brake lines and fuel lines, but they will probablly get in the way, its a good idea to push them out of the way.. 3 bolts holding it from underneath on each side, 2 on each side of the C channel.. thats only 10 hrmm maybe I missed some. At any rate, you can remove this with A-arms and all on it, I have an entire from assembly off a '69/70 sitting in a torn up SWB bed out behind the garage (you can see it in a bunch of my pictures)

the things not heavy, unless the suspension is still on it. Its best to have 2 people ready to move it at any rate, just because of its size.

10 bolts yeap, 3 on top side of cradle and two pointing out from inside frame rail threaded into the upper arm mounting bracket that is riveted to the cradle

the cradle stripped down is very light, lighter than you think, you will see,,

if you ar epulling cradle off thjen you wil not want engine in unless you want a big accident to happen to frame rails and engine

good luck

Hey guys,
Guess I should have clarified better...
I want to completely dis-assemble the front
cross-member (to rebuild all the parts),
ie, balljoints, shafts, etc...
While am I at it, i want to remove the
crossmember to clean it up and paint it.
How should I approach this:

1.] put the motor back in (for weight)
and pull the springs out, then pull the
motor back out, and remove the crossmember?

2.] Just remove the cross-member, but then
what is the safe way to dis-assemble it?

Thanks,

Are you installing new springs? If so,you can pull the cradle as an assy,then reach in with a torch&cut the springs to relieve tension. Then just install the new springs after the eng is back in place.....69 longhorn.

Well that is an idea, but I hadnt planned on
replacing the springs, (although I probably
should) The truck still sits very level and I am not sure even if I am going to keep it
at stock height...thats why I want to use the
old springs for now...if I decide later that
I want to lower it a couple of inches on the
front...only 2 max for me...should I go with
drop springs or new drop spindles?
But as of right now, I was going to use the
old springs....

a dropped spindle would be the best route,you should be able to get a 2 or 2 1/2". You can go up to 2 " drop on the spring......much more, & you will have geometry problems,& bump steer due to the tierod angles. good luck....69 longhorn

Here's how I would do it:

-Remove the front clip (optional but gives alot of room to work).
-Disassemble the front end.
-Pull the motor.
-Pull the crossmember/clean/paint/etc.
-Install the crossmember.
-Install the engine.
-Rebuild the front end.
-Install the front clip.

Good Luck
