Sounds like you need a shim....no need for a carrier spacer for a 4" drop and you only need that for excab trucks....dunno what you have!?

I'd try a shim first....for a 4" rear drop a spacer isn't needed in most cases. They are needed for a 6" rear drop. If a shim doesn't do it than the spacer will do it.

Shims install between the leaf pack and the axle saddles. The shim alters pinion angle by adjusting the differential position.

The carrier spacers install on a crossmember where the joint in the 2 piece driveshaft is. The carrier spacer alters pinion by raising the driveshaft and the joint. These only can be used on trucks with 2 piece driveshafts.

Both are easy installs for anyone who's done any suspension work.....the spacer is just a few bolts. The shims are a little more work but still easy.

i think I may just order the DJM carrier bearing kit and get it over with - dont even both with the shims - hopefully I'll be able to figure it out and get it fixed - did the 2/4 by myself so I hope I can figure it out
