67 shortbed rear end driving me nuts
 

So thanks in advance. I've installed CPP 4,6 DROP. cpp arms. Once I got tranny and motor in the rear seems locked at an angle. I've tried pulling the rear forward and back and can't get it. In pic the green wire is center. The string is running from centered trans. What am I missing.

What happens when you attach the panhard bar? Can you attach the panhard bar?

It pulls it one way or the other but the angle of the driveshaft connect doesn't seem to straighter out. Would the lack of l9ad cause ot?

I am not understanding what you are saying. If you drop the rear of the truck 4-6", you may need an adjustable panhard bar to hold the rear axle in the correct position. You may also need shims to adjust the driveshaft angle.

Your post is somewhat confusing but unless you have an adjustable track bar the only thing you need to do is bolt the track bar on and your good to go.

The rear end pinon/yoke will not be centered in the frame if that is your concern. (Very few axles have the pinion in the center of the axle.) Remember as you lower the truck the track bar will push the rear end to the passenger side and as you raise the truck the axle moves to the driver's side. This is more pronounced with the short factory track bar.

If you have an adjustable track bar then you want to center the wheels in the frame at ride height. Checking its alignment at the alignment shop just to be sure the truck is tracking perfectly straight can be done but it's not necessary.

Here is a link to how I aligned mine when I went to an adjustable track bar. Scroll to post 513.

I hope this helps

Post a picture of the complete frame, maybe stand on a ladder or something so we can see the overall showing the tail shaft of the transmission, in relation to the rear axle and pinion

Do we know for sure the tail shaft of the transmission is centered on the mount?

Did you replace the trailing arm bushings at the front of the trailing arms where they connect to the cross member? Could one of the bushings (drivers side specifically) be bad and allowed the rear housing to shift forward on that side? Assuming you have trailing arms.. ?

Is it possible the frame is a cut down long bed or anything like that? Have you checked the frame for square?
