    Installed D44 rear, vibrations at 20mph

    Yes, that is exactly what I'm saying. Seems to me that it should be angled upwards a bit more. The TC is angled down at 3* and the DS slope is 10*. Thus, the TC/DS angle is 7* and the pinion/DS angle is 10* (as mentioned in my prior post). These seem pretty close, no? Not quite sure I follow...

    Installed D44 rear, vibrations at 20mph

    To follow up on this... The driveshaft slope is 10* and I measured the pinion angle to be roughly 0* based on measurements take on the face of the yoke and on the flat spots on either side of the diff cover in the back. This equates to a 10* pinion / driveshaft angle. I found a previous...

    Installed D44 rear, vibrations at 20mph

    It's a fully assembled rear axle, with new gears, new discs, etc. I'll be calling ECGS first thing on Monday.

    Installed D44 rear, vibrations at 20mph

    DS u-joints are original (101k on them). I have some new ones laying around so I'll change them this afternoon and report back. Nevertheless, I had no issues with the 8.25, which from my understanding has a very similar pinion length.

    Installed D44 rear, vibrations at 20mph

    Hi all, I just wrapped up installing a Dana 44 rear axle that I purchased from East Coast Gear Supply (they make new casting, bolt in axle assemblies). I just went on a few test runs this morning and now have a vibration / shudder that starts at 20mph and picks up with speed. It lessens a bit...

    Maybe he meant c-clip eliminator? Edit: Johnnie Walker figured it out

    Anyone have experience with 2.5" Skyjacker Softride leaf springs?

    Does anyone have experience with 2.5" Skyjacker Softride leaf springs? I'm looking for a good quality 2" leaf spring and recently found these. Unfortunately, there are no reviews online and I can't find anything on the forums. Aside from these, seems as though there are a few ~1" options and...

    Head Swap Issues - Need Help Troubleshooting

    I will check the coil rail / spark. While the rail does fire in pairs, 5 and 6 are not matched together. 1 and 6 are matched and 2 and 5 are matched. What's the best way to check for a spark? I could do something like this video... https://www.youtube.com/watch?v=Sk_8TKMwyPo Redsnake - I...

    Head Swap Issues - Need Help Troubleshooting

    Another update: When I replaced the head I put new copper NGK plugs in. I pulled them today and found this: Plugs 1-4 show signs of combustion, while plugs 5 and 6 are totally clean. I confirmed yesterday that the fuel rail has good pressure and there is no leakdown issue. All fuel injectors...

    Head Swap Issues - Need Help Troubleshooting

    Yes, stays pegged to 49psi. Will confirm again tomorrow. Doesn't appear to be a leak down issue either. Another idea...could be a gas issue? The gas is 2-3 months old at this point, which I think it approaching the life span for 10% ethanol gas.

    Head Swap Issues - Need Help Troubleshooting

    Ok update... I confirmed that the fuel rail has good pressure (49psi). This led me to believe that perhaps the injectors had dried out and gummed up in the 2 months they've been out and exposed. I ordered new injectors and just got around to installing them. They had no effect. To recap: Jeep...

    Head Swap Issues - Need Help Troubleshooting

    Per the 2000 FSM the fuel filter located in the gas tank (requires dropping tank) and is supposed to be a lifetime part. Given that I didn't have a no start issue prior to the head swap, it should be fine.

    Head Swap Issues - Need Help Troubleshooting

    Ordered a gauge (will be in tomorrow) to check pressure at rail. Will report back when I have a number. I have not changed the fuel filter. Talyn - I misstated above. I did not prime the oil pump, I bled the fuel rail by turning the ignition on and off a few times. I'm thinking that maybe...

    Head Swap Issues - Need Help Troubleshooting

    Just ran it. Before I started it, I primed it a few times. The first time it ran for about 15 seconds then stalled out. While it was running it sounded mechanically fine (no knocking, tapping, etc.). Then I waited a minute and started it again. It started but almost immediately stalled out. I...

    Head Swap Issues - Need Help Troubleshooting

    There's oil in the head and on top of each of the rocker arms, so I don't think oil circulation is an issue (at least in the 10 seconds it's been running). I'm going to put it back together and run it later. Russ - I was under the impression that lifter preload didn't need to be adjusted...
