    Convert a Dana 30 front to a Dana 44 pumpkin with some welding?

    If this has already been discussed and I've just failed to find the post I'd love a link. So, Dana 44 front axles are actually quite affordable in the US especially considering their rarity (im just looking at ebay as a reference) but shipping to the UAE where I live is kind of expensive, at least...

    Rubicon driveshaft vibes

    I have a 2005 Rubicon with a 4 inch lift (probably Rough Country). The transfer case is lowered one inch, probably from Rough country too. All from the PO. There is vibration at around 70 MPH. It's done this since I bought it and It seems to be getting worse. I will be checking pinion...

    Rear Axle / Differential / Driveshaft Issues

    1998 Jeep Wrangler (SE) - was my first car when I was 16, just got it back after all these years (same exact car). Changed out the tires to 31x10.5x15 (no lift) and now I have shaking and loud noise after a few weeks of driving on the new tires. Shot the attached video to try and get a look at...

    Good Day! I recently got my first Jeep, 1997 Wrangler! Dream come true finally, now I need to give it some well deserved TLC. I've been doing little things like fixing blinkers, lights, fluids and such. Along the way I've noticed some things that I need advice on. I've attached a diagram and...

    Driveline Noise

    Hi all, I recently installed my Rubicon Express SuperFlex Adjustable LCA's. My TJ is on a 3.5-4" (not sure i bought it lifted) Rancho lift with stock UCA's and the owner before me had never installed control arms after lifting it. With the stock arms believe it or not I had no noises. Post...

    Do my camber bolts need to be adjusted after installing 4 inch lift?

    Just recently finished up my 4 inch suspension lift by Rough country, I know I’ll need an alignment but I also need my camber bolts adjusted I believe. I don’t know much about how the camber bolts work or how to adjust them, I had to put new ones in because I had to cut the old ones out when...

    My pinion angle just went out

    Ok so here is the deal. I bought this tj about 8 month ago and like and last weekend I decided to fix a leak that I had right on the SYE case. This jeep has a 3” or 4” lift Im not really sure, so it had a sye installed. So after I open everything up I found out that the oil pump was cracked so I...

    Another Driveline Vibration (research showed this should work)

    So, I read most of the threads about driveline angles... I SHOULD be vibe free. I have had 3 other jeeps with similar lifts I put together without vibes. So... I have an 05 TJ with the NSG 6 speed OME HD lift Extended LCAs (Synergy) Adjustable UCAs (Synergy) 1” MML/BL Rear Axle pointed up 9...

    Do I really need a transfer case drop kit for a 4" lift?

    do i really need a transfer case drop kit for a 4'' lift kit? i do not have an SYE currently and i just installed my currie/savvy short arm kit if that makes a difference. i have spoken to so many individuals with opposing positions on the matter. i know its a fairly cheap thing to do but i...

    Front angles?????

    Setup: 4” short arm, 1” body, 1” motor lifts I’ve installed a new Tera SYE kit on my 98 and now I’m putting on the driveshafts. The rear is simple to figure out, but I’m completely lost with my front setup. Out of the TC, my front yoke is at 81* UP. I’ve got a DC shaft, but I’m staring at this...

    Pinion Alignment for CV Driveshaft

    So you have installed your brand new slip yoke eliminator (SYE) on your transfer case and you just finished tightening the bolts on your new double cardan drive shaft (also called a constant velocity or "CV" drive shaft). Before you decide to take it out for a test drive, you need to adjust the...

    Caster angle off on one side?

    After my suspension install the steering wheel returns to center just fine, and aside from my vibration (yet to be identified) the Jeep drives perfect. I was measuring my caster angles today just to check, and the drivers side is 9 degrees, while the passenger side is 6 degrees. I measured them...

    Pinion angle changed

    Okay, so I had my rear driveshaft angle at about 16 degrees and the rear pinion was at about 15 degrees when I completed the my Currie suspension install. I never noticed any vibrations until today because I hadn't been at highway speeds until now. Anyways, I noticed over 40 mph it definitely...

    How to adjust caster?

    I know how to adjust the caster with my new control arms. What I am trying to figure out though is the process for doing so. I'm assuming that the vehicle needs to be completely flat on the ground in order to measure the caster angle and pinion angle, yes? So, let's say I install these...

    How to properly set your pinion angle

You put that lift in your vehicle or changed the engine, transmission or transfer case or differential maybe all of the above and now your go anywhere four wheel drive baby rides like a out of balance washing machine. Or now that you've got all that raw power & torque...
