Measuring Thrust Angle and Rear Axle Square Alignment 2015 Jeep Wrangler JK / JKU

[youtube https://www.youtube.com/watch?v=rUCMRLVBaxE&w=640&h=360]

I have been suspicious that my rear axle is not completely square in comparison to the center line of the Jeep... so in this video I show you how I measured that axle alignment (which also impacts the thrust angle) and then what I did to fix it.

  2. You need some kind of skids on your RLCAs before they it gets to bad. Rock stars , Artec, Synergy.

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

  5. If I may ask...what axle mods for the front axle do you have to run 37's? Welded C Gussets? Welded Truss? Chromoly Axle Tubes? I would like to also run 37's on my Rubicon but as most can't afford an entire axle swap upgrade. I also 4x4 offroad wheel my Jeep. Thanx much!

    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.

    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???

  8. Invest $5 in a deadblow dude, why did you senselessly abuse you control arms

  9. Why did you not take it back to the shop that installed the lift after you had the alignment done? Why didn't the alignment shop correct the thrust angle while they had it on the rack?

    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.

    Yeah...I have one. Bothers you more than it bothers me I guess. The bottoms of those arms are not pristine... I'm way past worrying about marks and scratches on them. :-)
