Best way to check the angles? I have delta 3” arms and 3” front dobinson springs.
Having Dobinson springs can very well mean that your lift is more than 3” unless your rig is quite heavy.

I explained how to get an idea of your castor angle in a prior post. The main thing here is that you don’t spend money on a DC shaft that won’t correct your vibration issues. What you also need to determine is the angles of the companion flanges relative to each other and your actual lift height as measure from the center of the hub up to the fender lip.

Posting a photo of the Front driveline installed from the side would be helpful to us.

Is the pinion nut still tight? Does it feel sloppy when you twist the flange left and right?

Hold an angle finder tool on the diff pinion flange (or hold parallel to the flange) and also the t-case flange.

If you don't have an angle finder, download an app to your smart phone, and do the same thing. Hold the edge of your phone parallel to the pinion flange. If you're careful, a phone app will give you a reliable reading

Currently have the driveshaft out. If I remember the delta arms are supposed to pivot the pinion angle up? I just recently had pinion bearings replaced and professionally torked before reassembly

24” center of hub to fender. 3” dobinson spring with bumper and bug warn winch. Have Icon 3” in the back and netted 24” as well
 
Castor correction devices no matter what they might be always pivot the pinion down supposedly to where it was before lift kit install. Just don’t go and order a DC shaft before we know your angles (castor, driveline installed, and both companion flanges parked on a flat floor).

24” hub to fender some would call 3” lift and some would consider that more like 4” lift. Did Delta request of you measurements of the front track bar bolts up from the floor in order to decide which arms you needed?

I didn’t get their feedback, just purchased the arms for 3”. Now realizing that was a mistake.

if looking at the two pinion flanges, if we called the transfer case flange flat, the pinion flange is tilled up beyond flat as compared to tc flange.

whats your take on the phase of the front drive shaft?
 
Castor is at 1 degree after arms and alignment. It was negative prior
1* positive castor angle is not enough and proves that your lift is taller than 3” because Delta’s arms would put you on the fat side of Toyota’s 2*-4* range if your lift was actually 3”. It’s time to temp install the front shaft to measure the angle created between the shaft and the face of the companion flanges at both ends. Posting a photo would help. Did you download an angle finder app?

Out of phase was done at the factory because both U-joints angled downward toward their respective mounting points. Yours is now lifted and requires the driveline to be in phase. I believe pics the difference was posted earlier.

Got it. Will slap it back in in phase and try to take pics. Sounds like I’m spending $2500 on new arms and the dc shaft?

Or lower the vehicle. This is one of the two reasons I went to part time.

If it turns out that you need the 4’s you can always post a trade offer in the Classifieds. I’ve seen some threads where guys were going lower and were looking for a trade to 3’s

You could alway do a cut and turn that's the real fix ! Most just get the DC shaft from TomWoods for around $600.00
