Move/Center Rear Axle

I've installed lower and upper rear control arms today. How do I physically move the axle back to it's "intended" location? Not looking to get 2", just as much as I can to center the wheel in wheel well.

Front to back you have to adjust the length of the arms...did you get adjustables? Left to right or driver to passenger adjustments are done with an adjustable track bar....

Which direction are you talking about?

If you adjust the axles out farther then stock ( front axle forward, rear axle rearward) you will also require new longer driveshafts.

I'm talking about moving front forward and rear further back. I'm really only concerned for the rear. Not a side to side adjustment. I understand I need to adjust length of arms. How do you move the axle back so that the holes in the arms that were just lengthened (per metalcloaks specification) will fit into the axle? Again, not talking about major movement here, just an inch or so. Is there a method or trick for this?

with every thing loose the axle will move back. just stick a floor jack under it. use the upper arms to set pinion angle and the lowers to adjust back.

Loosen all the rear control arm bolts....

Undo the rear lower axle side bolts and set to length...did you get measurements in your lift kit? With the axle side disconnected you can rotate the axle to line up the holes....it WILL be a pain getting the bolts through....

With the lowers in place take off the axle side uppers and put a jack under the pinion and Jack up the pinion to the angle you want and then lengthen the arms until the holes line up....

Which MC lift? 2.5" or 3.5"? What were the rear lower arm lengths they said to set them at?

Jadmt and I said the same thing we just do it opposite....I do the lowers first then the uppers for pinion....

I feel if you do the uppers first for pinion then do the lowers you will undo the pinion angle...

I moved my axle back about 1" using the rock krawler upper and lower arms. I also tapped new holes to move the swaybar back an inch too. I set the arms to the recommended lengths and fine tuned to get pinion correct. I think you have to specify the correct arms from RK when you buy them to get the correct length. I don't know about MC.

Thanks guys. I will attempt per above. It is metalcloak 2.5. They give dimensions for 3.5, but say you'll need to adjust for 2.5 with no specs. Read somewhere to do factory + 0.5 as a start, will see where that puts me against MC's dimensions. I bought a kit that had the front uppers only, and I bought the rest of the arms now. Did pinion on the front with the front arms no problem. I understand jack on the diff or jack on the pinion to get the movement you need, but couldn't find anything on moving the rear axle toward the bumper on the inter webs. Appreciate the help!

Rear lower length that they spec is 20 and 7/16" for a 3.5" lift.

A ratchet strap from the bumper to the diff makes the whole process very simple to do by yourself. BTW I run the AEV 2 1/2" lift and I added just over 1" to all 4 rear arms to get centered up to run my 37s. Tweaked the upper arms a bit to get the pinion angle I wanted also. My arms are CORE 4x4.

You can set that for the 2.5 inch too

Ever have one of those dumb moments? Of course you have to remove the control arms to move the axle back. Thanks to you guys, my axle is back where it belongs. Appreciate your help.
