Just picked up a crew cab.. Let the repairs begin...

From the pics that you have here, I want to say it's a truck frame not a suburban.
The body mounts seem to be unmolested and they are not the same on a suburban.
PLus the end of the frame in the back looks like a truck end to me.
As for the front axle, it's not a D60 for sure but you didn't show the pumpkin to see if it's a 10 bolt or a D44.

need stright shot pic of the front diff.

need a basic inside fender wheel well pic of the shocks to see if true 1ton or 1/2-3/4 ton section frame.
basicly shouck on outside of frame in stock location its 1/2-3/4 ton if shocks mounted inside the frame stock then 1ton.

I said it first.

ya so you wana prize

ya so you wana prize

Yes what do I get??

No it's just funny, he does post a pic of the mounting on the passenger side which clearly shows it's not a D60, but then he assumes it's a D44?
or he knows it's a Dana axle but he wants to confirm it's not a 60?
Do you agree with the statement truck frame?

I do believe that's a 10 bolt, note what appears to be a casting "ear" on the top, drivers side of the diff.

my screen name should tell the story on i know its not a 60. just cant tell for sure if 10 bolt or 44 like you in the pics.

and yep looks all frankin truck frame. but looks well put together with good size fishplates in the welded area's.

and here ya go imiceman44

I know its not a D60.. The PO said it was a D44.
Here are pics

Its a 10bolt

 

[nvrenuf]

I was right.

I bet the fumes in that tool box are to die for.

And the best thing is, its a 1 ton frame!

The height of the rails is taller than a Suburban frame. Subs have frames the same height as K10's and 20's.

Looks like this is a true crewcab K30 frame then.

Look here, real closely:

The rear shock is visible here. Its on the inside of the axle housing. Closer to the driver. The passenger side would be outside the housing tube, closer to the rear bumper.

K5, 10 and 20's have them the opposite position.

This is a true K30 frame. I also noticed the t-case crossmember is the flat style, of which is correct since he said the frame is an '84 and thats the last year for the flat 'members. '85 went to the double-hump 'members.

Here are some pics of the frame sectioning. The diamond shaped fish is behind the cab the other is below the front door.

I'm questioning whether this truck was originally a regular cab truck and someone lengthened it to add the crew cab.

Why else would it need to be cut, plated and welded behind the cab and below the door? Shortening a frame for a shortbed would only need to be done behind the cab and at the very end of the rear frame horns.

Are you saying that it was a C&C frame?
Because if it was a regular long bed, the frame isn't as tall, or am I wrong?

Looks like it was sectioned longer with another section of a 1 ton frame in order to keep the height of the rails.

That don't make sense to have the 2 different places to shorten especially since nothing needs to be done to the frame under the floor. Nothing. Thats my first clue it must have been lengthened.

 

[crawdaddy]

Interesting. Are there any other pics I could take that would tell you for sure.

Take a shot under the truck of the whole underside from the shackles of the front springs to the front hangers of the rear springs.

I'm curious to what the area of the rails look like where the t-case crossmember is sitting.

Take a shot of the t-case crossmember, too.

Last, go to the very back of the truck and check around the very end of the frame horns to see if they've been shortened.
A long bed frame is slightly longer than a short bed frame at the very end. If you put a short bed on a LWB frame, the end of the horns will protrude a bit and need to be shortened. Just look for cut marks and lines. The bumper holes won't be the same place either and chances are yours will be welded on for a quick attachment job.

Ok tried to get some pics but its starting to get dark and my camera sucks. But hopefully they help.

 

[sweetk30]

possible 2wd to 4x4 frame splice.

and look mom i got ears on my pumkin = 10 bolt yep.

and yours might be a short bed crew cab now. but mine is shorter. 4ft 6" behind the cab . and no frame splice at all.

 

[thatK30guy]

Yeah, gonna have to wait for better lighting. Too dark to see.

This pic:

Shows the crossmember sitting on top of the lower rail. K30's up to '84 do NOT fasten this way. They bolt from the bottom of the rail.

The K30's from '85 up to '91 using the double-hump 'members sit on the inside of the rail like your pic shows. But those 'members are shared with the rest of the K-series trucks since they mount UNDER the rail and the K30's sit INSIDE the rail to make up for the frame height. Again, I have pics of this setup on my '85 and '87 tonners.

That 'member is also NOT a K30. A K30 'member will be "flatter" than yours. The bends are too deep to be a K30. I have a 'member at the shop and can take a pic of it tomorrow for you to understand.

Need to wait for better lighting to get better views under there. This rig is like a puzzle with pieces to try and figure out.
