Re: Lost My 65
So I took out the rubber mount between the transmission and cross member to see if dropping the back of the transmission would lessen the vibration, and it did.
So I'm going to try a combination of dropping the pinion angle down with a wedge, and lowering the back of the transmission until they're parallel. Thanks for your help. ![]()

Re: Lost My 65
So it appears that the trans crossmember should have more of a drop in it? That crossmember has the same amount of drop as a factory crossmember that I measured. Although the engine mounts have an effect on the engine and trans angle as well. The truck I measured had the '60-'62 factory V8/auto trans engine mounts. They may be a little higher than your engine mounts. Don't know for sure.

Re: Lost My 65
Tilted the axle forward to get the pinion angle closer to parallel to the transmission - trying to get the slight vibration out. Not getting there.

Re: Lost My 65
Sorry to interrupt here but wouldn't this thread be more appropriately located in the Projects and Builds section? I didn't take the time to read all 16 pages but it sure seems like a build thread from what I'm seeing. Nothing wrong with that but it doesn't really belong in this section. Moderator? Thanks.

Re: Lost My 65
It's far from a build thread.
But I'm fine with whatever staff thinks is best. . Thanks for the video, lowbuck. It helps seeing a visual of what's happening. I probably should get an Angle Finder and get the angles correct.

[QUOTE=LostMy65;7505769]It's far from a build thread.
But I'm fine with whatever staff thinks is best. Sorry. Please don't take offense at my comments. I'm just trying to figure out what is the subject of this 16 page thread? It appears that it focuses on one specific truck and its evolution over the last 5+ years. I guess if that's not build thread material, I don't know what is. Call me OCD or whatever but I prefer to have things in their proper place so as not to clutter up the general board with 16 page threads all about a single truck. Neat story, btw!

Re: Lost My 65
I don't care exactly "where" this thread is on the message board and I don't think anyone else should either if they aren't a moderator. I think someone's picking nits here...

Re: Lost My 65
Just to clear things up, there is no hard set rule that build threads have to be in the Projects area. The Projects area tends to be where most would look for a build thread so most folks want them there. Others start a thread in the general area, not really seeing it as a build thread (like this one) that over time becomes one. We won't generally move them unless requested by the original poster.
As for now, unless LostMy65 requests to have it moved, it will stay as is.

Re: Lost My 65
Either the heavy piece of diamond plate steel in the bed, or a combination of that and old weak springs, the truck can't hardly handle a load. A guy I met yesterday gave me these heavy springs. I figured I give them a try.

Re: Lost My 65
Those look like 1 ton units...
You might consider swapping the springs out for a HD set of air springs.. AKA "bags"... I had a set on my 3/4 ton. I ran separate lines to Shrader valves on my license plate and they worked fantastic.

Re: Lost My 65
Yeah, bags with Schrader valves is definitely on my list for the future.
These were free, so I figured I might as well install them. The truck has air shocks, and the only way I could keep the tires from rubbing on the fenders was to keep the shocks aired up. Which gave me a stiff ride. These bigger Springs have my butt up higher than I want, but the wheels I have are only 25" tall. If I was to go to 28" tires, the wheels would be an 1-1/2 closer to the fenders. These will tide me over. ![]()

Re: Lost My 65
I used 30 spline 10 bolt axles from a nova diff..
Installed those into a, narrowed for the axels, 86 C10 8.5 inch 10 bolt. Redrilled for 5 on 5 and used truck drums.. this setup put the same wheels you have square in the center of the wheel well. .. :-)

Re: Lost My 65
When I went to swap in the 3.73 rear, I popped a drum off to check the brake shoes. The springs looked clean, and the shoes were good, so I went with that, also because I couldn't get the other drum off. :-(
Well yesterday, when I pulled the wheels off to install the bigger coil springs, I figured I'd pop off the other drum. Backed the star all the way off and still couldn't it off. Three flat bars wedged in between the drum and the backing plate, and it finally popped off. Good thing. I've never seen shoes so bad. ![]() ![]()

Re: Lost My 65
It looks good. Just throw some cargo in there and it will take care of that rake.
BTW, I do like the rake.

Re: Lost My 65
Still haven't resolved the vibration issue.
Below is a pic of the way it was at first. #1 And then the way it is now with three heavy washers under the back of the axle perches. #3 In all positions, I haven't really noticed a significant change in the type, intensity, or duration of the vibration. And it still occurs right around 37mph or 1900 rpm. My thinking is it has to be the driveline itself. If it was the pinion angle, I'd expect the vibration to change in some manner. But in all three positions in the pic below, the vibration remains the same. ![]()

Re: Lost My 65
Yeah #3 is how it should be. Have you checked your tires for separating plies? I have had tires start to separate, causing a vibration at certain speeds.
