Help? Do you have a Ford 8.8 and 4" lift?

If you have a ford 8.8 and a 4" lift I need your help. Easy request Can you measure from the ground to the bottom of the axle flange where the driveshaft goes? I need that measurement.

Thanks

Im guessing you are wanting pinion flange measurement. As stated it will vary between vehicles. Even with the same size tire. I am also guessing that you are trying to find the correct driveline angle. Somebodys measurement may get you in the ballpark, but I wouldnt trust it. The correct way would be to use an angle finder which can be found cheaply at home depo or lowes.

I've got that set-up but K4KAS is right. If you're trying to set the pinion angle put jack stands under the springs (so they are loaded with the weight of the Jeep) with the axle sitting in the perch on the springs. Adjust the angle of the pinion until the pinion and the driveshaft (obviously need the driveshaft installed) are straight and at the same angle. Some people say to have the pinion 1 degree lower than shaft to allow for axle wrap under acceleration but I didn't do that. Then tack weld the perches to the axle tubes. You can either weld it out under the Jeep or take the axle out to do it. I welded mine under the Jeep. I'll go take the measurement you've asked for a little later and send it to you.

The dimension on mine is 14 3/4" to the bottom of the flange. Photo attached. You can't really tell in the photo but he axle pinion and driveshaft are parallel (at the same angle).

^^^ What he said ^^^

Use an angle finder and point it 1 degree down from what you need.

I see a $1k 8.8 swap there and you didn't buy a $10 angle finder? Cool!

For what it's worth I recall my pinion being at 18 degrees and the shaft at 19.

$1k? someone got screwed? I didn't pay close to that. Axle at JY was $177 (4:10 w/LSD) + misc parts to install and labor $150

17 3/4" is what I got on the DS with a 4" lift and 33x12.5x15. I was told 17 1/4" to 17 3/4" was a common measurement for a 4" YJ lift. You got 19"?

I will measure from ground to flange in a few and post.

Live and learn!
