Centering and aligning your 8.8 on install.

Ok so for those that follow, I've got my YJ down to the frame at the moment. I'm ready to sling the 8.8 under it today after work, just one question: how are you all centering this axle? Just wing it with a tape measure? I want it to not only be laterally square but I'd like there not to be any angles at play here. I don't want there to be any angles causing the Jeep to "dog leg" down the highway. I've got my 8.8 kit from ruff stuff with their SUA perches. I'm thinking put it all together with nuts and bolts and get it as square as possible, then tack weld the perches and pull it out to burn them in all the way?
One idea I had was to paint temporary square lines on the floor and use plumbobs off the frame and axle to get it 100% square.


Help guys! I want this to be a rolling frame again! Haha.

I used a tape measure yup.

get the axle under the jeep, and measure from the outside of the perch to the hub.

When both are the same you are centered

I assume you are setting pinion angle at the same time, so you want the weight of the jeep on the axle.

Well....... That's kind of an issue as well. I was just going take a stab at the pinion angle and hope it works out. I'm still putting together the Ford 302, T-18, NP231 SYE driveline and was hoping I could wing it. The tub is off the frame at the moment, and there is no motor trans or tcase in place either. Basically it's a naked frame, but it needs to be a rolling frame again to move around the garage. Should I wait to weld it all together and just leave it bolted together after I get it in there? I don't want to jack up my whole project but after I weld the peaches it's my take that you can't readjust pinion angle easily.

you can leave the perches unwelded, or just tacked until you get the rest ready. Getting a good pinion angle by math is probably not going to be ideal. The should not be any issues with being square. The perces are self centering and the centering pin on the springs will line that up. The only issues are left/right and the pinion angle.

+1 and for the shock mounts I got the measurement between them off the D35 and centered them on the tubes.
