    D30 Gear Issues - Dummy Check.

    Hey all, I'm looking for some advice on troubleshooting a potentially bad gearing setup in my D30 axle. 4.56 G2 gears, Detroit TrueTrac. I have a weird rumble style vibration clearly noticeable at speeds above 40mph, and very slightly noticeable at 15mph and up. I have tried, but cannot get it...

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    Update: So I broke my breaker bar at the boneyard trying to pull the driver side shaft, went to Lowe's and grabbed another, broke that one too I left in frustration and ordered a fresh set of chromoly shafts and full circle clips. While it solved specific front end vibrations, apparently my...

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    I just swapped out the passenger axle shaft. Noise has been reduced by almost 80% and no longer sounds like it is coming from the passenger side, mostly right under my feet. My theory: I'm assuming when I busted out my rusty ujoints, I managed to slightly knock the axle shafts out of...

    Running Falken MT/01s. I don't believe they are directional.

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    I did have a passenger confirm the front passenger side for the noise. No change with brakes, only speed and turning. I can't imagine it being something rubbing or flapping, there's not too much there besides the rotor and caliper. No dust shield or inner fender well. I jist picked up an...

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    Currently running no front driveshaft. Waiting for rear spacers to fit my 35s on and also did WJ rotor/caliper upgrade so my old 32s on 15s don't fit.

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    I'm positive the gears are set correctly and they have a good contact pattern. To cross the gears off the suspect list, my backlash was slliiightly changed when I redid the pinion, but the noise did not change at all. Gears are a G2 set. I also have a set in the rear 8.8 with no issues. I took a...

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    I actually just swapped on fresh treads today to test that. If you're referring to the axle hub bearing, yes. Brand new Timken units, and today I also swapped out the passenger side bearing to something different to check that as well. No difference with the tires and bearing.

    Frustrating dana 30 cyclic front end noise after regear+truetrac.

    1996 Jeep XJ Dana 30 reverse rotation axle. I recently did a front end regear (4.56) and installed a truetrac as well as upgrading to 35s. Did other small things like axle seals, hubs, and axle ujoints. I now have an obvious front end noise which sounds similar to a wheel bearing, but does...
