I have a transfer case drop, i had it installed, but everything felt a little loose. By that i mean the shifting, and when i drove at 50 the shifter would be rattling around. installed new transmission mount and removed drop, it feels way tighter, but in first gear i get vibrations or shudders, especially when turning.
Pics of the angle, I think the pics make it look worse than it is....
Did you install a lift? If it is > 2" you may need more than the drop to get your pinion angle within spec. I'd resolve sooner than later, the vibes will cause premature wear on your joints.
In my opinion the TC drop is not the problem, The differential angle is. You will need adjustable lower CA's to rotate the rear axle pinion downwards to get the spline in the TC, in a parallel line with the spline in the differential. This will adjust the loads or resistance on the u-joints on both ends of the driveshaft, to be equal.
Based on the pics, that steep of a pinion angle is not going to be resolved with a MML or TC drop. (The angle seems like it is closer suited for a SYE/CV shaft.)
The owner first needs to check his output shaft angle and compare it to the pinion angle before doing anything.
allright, i checked my angle and got ajustable upper rear.
Firstly, did you know that you can use your phone as an angle finder? theres an app for that!
so my drive shaft coming out of transfer case was 84 degrees, and my pinion angle was 78, 6 degrees off. (this is with rotation lock on my phone turned off, so it was measuring from 90 not 0/180)
I was told to keep tires on, remove upper control arms, remove driveshaft, and pinion would drop (supposed to keep it raised with a jack). However, mine didnt drop. i eventually took the jack out, and it remained at the same angle. I could jack it up to change the angle, but that was going the wrong way.
what am i doing wrong? I had to install the adjustables at the same size as the stock ones...
If all you have is a 3" suspension lift with all stock control arms, just do a 1" mml as suggested above and it will bring the angle of your t-case in line with the angle of your differential....it's been done a million times.
