Probably not what you are wanting to hear... but I have a Dynatrac ProRock 44 Unlimited... so I went axle swap! :-) But.. I started with a D30. With your D44, I think the things you mentioned would be adequate depending on how you wheel. Feel free to jump into the o3djeeps Facebook group and ask. I am sure folks will be happy to help figure out what you need.

o3djeeps [ OVERCLOCK3D Jeeps ] Thanx for the reply. In order to run 37's I'm going to attempt and upgrade that front Rubicon axle only with bare minimum with the following: C Gussets, Chromoly Axle Shaft and HD Ball joints. I'm going to skip the welding of the truss. I do rock krawl but I do so slowly and carefully with a light foot. I hope this will be enough to sustain my 37's. Fingers crossed. Your thoughts???

So.. A couple of things. First.. I didn't want the alignment shop messing with my Jeep...After we got it on the rack, I had zero confidence that they could handle my job and they agreed - so I got the readout and we decided to call it good. Second... my lift over 2 years old... so I'm not going back to them. The reason I needed someone else to do the install was because the long arm kit required welding new brackets...and I don't weld. The small amount the thrust angle was off isn't really a big deal, but I just want to make it closer to perfect than that.

10/4

Jason Thissell I'm happy. It's essentially just the long arms and brackets that are Teraflex.

I would assume very little if noticeable. The tolerance of the thrust angle was .25 degrees, he was at .30 degrees.

I think so but you would need to make sure your pinion angle is within specs

I just adjusted out the one side. It really depends on your situation and it if makes sense to shorten one side while lengthening the other. It has to be the opposite on each side. If you lengthen them both then you accomplish nothing other than moving your axle back.

​@@o3djeeps did you extend with both rear upper and lower CAs? or just one or the other? EDIT- rewatched, you did both upper andd lower. I think I'm rubbing slightly on the pinch seeam as well. and looking to move the rear axel back just like .5 of an inch. Won't this hurt a number of things? brakelines - pinion angle, driveshaft length, etc etc ?

Do the lift blocks come with alignment pins and holes. It's not common to install blocks that don't come with centering pins and they shift off center slightly. That's where I'd start looking. It's sounds to me like the blocks are allowing the axle to shift.

o3djeeps [ OVERCLOCK3D Jeeps ] Yes, the blocks do have center pins and they are tapered. Pins line up, shorter side taper is pointing forward. They are installed per the instructions. I’m gonna inspect leafs, truck bed, and do some frame measurements. It’s driving me crazy! Thx for your input...

I know nothing about a Silverado, but assuming it's a solid axle vehicle, the axle shifted to the side because of the lift. If the track bar bracket that probably came with the kit doesn't allow you to correct that you'd need an adjustable track bar - that will allow you to center the axle under the vehicle. Essentially replace the current track bar with an adjustable one and turn the adjustment sleeve until the axle is centered, then tighten the clamps.

Troy Powell I know man... they're on the list...hahahah.

Not sure how you have more questions than answers. It’s pretty simple.
