    LJ or JKU for family wheeling?

    I have 2 kids that are around 10 and 12 years old. We have had the LJ Rubicon (3" lift on 33s) since they were 1year old and 3 yrs old. We also have friends who have kids about the same age and they drive a JKUR (3" lift on 35s). Every couple of years we take a trip together out to CO to do...

    JKS JSPEC suspension kit

    OK, I'll try to get some measurements for you tonight. I'll see if I can get pictures with the tape measure so you can see exactly where I am at.

    JKS JSPEC suspension kit

    I'm not sure what measurement you want. I used 2 hockey pucks bolted down on the axle pad. So my upper spring seat to my bumpstop is the same as factory. Maybe I'm misunderstanding. I'm really tired tonight. Let me know if you want something else. I'm happy to run out and measure things...

    Does control arm bushing composition affect ride quality or NVH?

    If you look age post #451 earlier in this thread, you will see a picture of the reinforcment ring on the Rancho bushing but not the Synergy. I did not notice this difference at the time. Also reading my comments in that post, it appears the Synergy was looser right from the start. I did not...

    Does control arm bushing composition affect ride quality or NVH?

    Unless there is something else going on that I am unaware of and If I remember correctly from an old thread several months ago, I think the problem was that some of the DDB bushings were showing premature wear. If you look at the DDB bushings you will see that some of the bushings have a...

    Dave Kishpaugh's (Jeep West) geometry correction brackets are now available

    For those inquiring minds... If I'm not mistaken, these are the geometry correction brackets that Dave has been using to correct control arm angles. Does he have them for both front and rear? Axle and frame mounts? What all does he change in his typical builds? The only one I can clearly...

    Do I need to adjust pinion angle with a 3" lift?

    That is exactly where I am at. The vibes are so minimal most people would just ignore it. And I am tempted to do just that. But I don't want to be stranded on the side of the road somewhere or on a trail in CO and ending my vacation early, because I neglected a small vibe. I did get a...

    Harmonic vibrations in Jeeps: A new theory (please read!)

    Thank you. That is what I thought was happening, but I was getting confused by comments in the other thread. I already have adjustable control arms. So maybe I will just extend the lowers a little to see if I can get everything back to parallel. What is the best way to tell if my stock...

    Do I need to adjust pinion angle with a 3" lift?

    Thanks guys. jjvw - I never thought about looking at the back side of the differential for a place to measure angle. That will help. AndyG - I'll have to do like you said and get under the Jeep and take some angle measurements with it loaded and unloaded. Its interesting that you said that...

    Do I need to adjust pinion angle with a 3" lift?

    Thank you gentleman. I'm going to have to do some jacking around on the Jeep and watch the pinion. I could have sworn the angles changed when I lifted it. But if I am wrong on this, then my whole theory is wrong. And if that is indeed the case, Jerry already provided multiple solutions for...

    Do I need to adjust pinion angle with a 3" lift?

    Thank you Jerry for helping out. I know your knowledge of the Jeep world is far greater than mine. So I'm not trying to argue, I'm just a little confused as to why you think that my pinion angle and transfer case output shaft are still parallel. They were parallel when the Jeep was stock, but...

    Harmonic vibrations in Jeeps: A new theory (please read!)

    I haven't read through all of this thread yet, but if a couple of you guys don't mind, please check out my thread and some of my thoughts on setting my pinion angle. Am I off base on this or does my logic fit the situation...

    Do I need to adjust pinion angle with a 3" lift?

    I wondered about that. Guess I should have crawled under there and looked at it before I asked. Thanks for being kind in your response. Sorry, that was my mistake to say out of phase. That is something different. What I meant to say was simply that after the lift, I don't think my...

    Do I need to adjust pinion angle with a 3" lift?

    Why wouldn't the front cause this problem? With an LJ the shafts are very similar in length. In regards to the rear pinion angle needing to remain parellel to the output shaft, that is why I thought I might need to tip the pinion back down. I didn't take a measurement when I lifted the Jeep...

    Do I need to adjust pinion angle with a 3" lift?

    I found this comment while reading through some old documents I saved from Nth Degree. I don't have the Double Cardon drive shaft, but I think it might still give me some insight. I'll need to measure some angles and see what I have. But the comment about feeling the vibes under load is what...

    Do I need to adjust pinion angle with a 3" lift?

    The tires have 18,000 miles on them. They are starting to get a little louder than they were new. But they are still pretty quiet. The noise wasn't a constant hum though. It was more cyclical. Can tires do that? I was thinking about the extra weight as well, but I was wondering if it was...

    Do I need to adjust pinion angle with a 3" lift?

    I have a 2005 LJ Rubicon with a 6 speed manual transmission. Last summer I installed adjustable control arms, and set them at the same length as my factory control arms were. Earlier this summer I swapped out my 2" springs for some 3" JKS coils. I hadn't noticed any vibes until this week...

    Front track bar: Currie or JKS?

    An updated if anyone cares. I got the Moog K3147 pressed into my front (Moog) trackbar and it is definetely an improvement over the stock Moog bushing that was in the bar. (Even though the stock bushing appeard to be a double element after I inspected it closer.) The trackbar only has...

    Front track bar: Currie or JKS?

    Since we have completely overtaken the thread, I'll go keep going. My apologies to the OP. I hope you still got some help out of this thread. So I looked at the Moog K3147 that I purchased for my front bushing. It has 2 different numbers on the bushing. They are very hard to read, but it...

    Front track bar: Currie or JKS?

    So the Moog rear and the OEM rear used the same bushing. What was the number on that bushing?
