Driveline angles

Is my

Rear driveline angle good? I have a 1997 tj with 4 inch suspension lift, 1.25 body lift, 1 inch motor mount, and 33 inch tires

Pinion looks slightly high from what I see. I would recommend a SYE with a 4 in lift from everything I have read.

I've seen guys running a SYE with 3" of lift. It's not a mater of what you want but what you need.

The only correct pinion angle is that which is exactly the same as/parallel to the t-case output shaft's angle. As shown below.

A SYE kit & CV driveshaft is STRONGLY (!!!) recommended once you get to the 4" suspension lift height with the SWB Wrangler TJ.

Read threw this

http://65.170.161.218/~spicerpa/site...stallation.pdf

It explains the proper set up for a driveline.

While without measuring the angles of your driveline I can not say that you require a double cardan (referred to as cv) drive shaft. It works by splitting the driveline angle between the two u-joints that are close together. The other real issue with a lift is driveshaft length. The further out that the slip yolk is on the shaft the higher the chance for vibration and failure.

Why does there appear to be a gap between the tc skid drop spacer and the frame in picture #1, and what kind of tc skid is that?

Just looks like that from the photo. I have one inch transfer skid spacers installed by the previous original owner. And i believe it is the stock tc skid plate?

After looking again with these tired eyes, it now does look like it. I think it is just the angle of the pic. that was making my eyes see a dip under the tc.

With a 4" lift 1" mml and what looks to be a 1" or so TC drop you'll probably be okay driving around on the street. BUTT if you get out and flex it your angles will go past what the U-joints can handle then they'll bind and bust the back of your TC off.... Not Pretty or Cheap.
