    Humming on deceleration

    Yes, I removed the driveshaft making sure to mark it‘s orientation. The u-joints held their position (no flop) and moved smoothly. Caps were filled with grease and everything moved smoothly. After I tightened the nut, I also marked the nut and pinion with a paint pen so I could see if it...

    Humming on deceleration

    Well, pinion nut was as loose as a goose. Once I got everything cleaned off the rear yoke, I saw that there was only one thread showing. I couldn't turn it by hand but once I put a socket and ratchet on it, it turned easily. I tightened it up and removed the play that was showing. At least I...

    Front Diff and Suspension issues

    Update: Just to close the loop for others who may run across this. Shop is giving me hell saying that there is no problem. It’s right and the problem is my transfer case. I’ve been busy doing other upgrades and repairs. Today I finally had the chance to look deeper. Front that was...

    Humming on deceleration

    Ok, so u-joints appear and feel ok. Tight but not overly so. Nice and smooth movement. Pinion.....well let's just say it ain't good. It does have play but the play seems limited to in-out vs up and down or side to side. I couldn't locate my socket that fits the pinion nut during lunch today...

    Humming on deceleration

    I’ll check that this weekend. As far as the fluid goes I don’t remember what I used specifically but I do remember it said no additives. GL-5 compatible comes to mind.

    Front Diff and Suspension issues

    I’m sorry if these questions are “basic” or something else. Like I said earlier, this Chevy 4wd system is new to me. I’m trying to learn and figure things out.

    Front Diff and Suspension issues

    Vehicle is jacked up with the drivers side on the ground. I’m going to take it back to them. I have the intake off right now waiting on the injectors and intake gaskets to get here. if I put it in 4wd while rolling 5-10 miles per hour on dry pavement, it will stop forward motion of the truck...

    Front Diff and Suspension issues

    it is rotating more. Using the rear tire as the “control”, one rotation of the rear tire turns the front more. The tape ends up at about 2 o'clock On the front tire.

    Front Diff and Suspension issues

    Is this a valid test to verify having matching gears. Mine has the G80 option. If so, I’m afraid I may have an issue.

    Front Diff and Suspension issues

    Standing still. I'm sorry I wasn’t clear, it is the electric pushbutton version. I'm still learning. All my previous 4wd experiences were with a manual shift/ manual hub 91 Bronco.

    Engine bay wiring harness - heat protection.

    The front axle 4x4 actuator harness goes from the front axle to a mounting point on the frame about 2” from the exhaust manifold. It then runs along the frame parallel to the manifold then goes down before coming back up behind a heat shield. From the mounting point on the frame all the way...

    Engine bay wiring harness - heat protection.

    I was troubleshooting an error I was having with blowing fuses. Fuse number 24 kept blowing. as I was checking the wiring harness for a short, I found that much of the heat protection where the wiring harness goes along the exhaust manifold was dried out and crumbling off. What is the best...

    Front Diff and Suspension issues

    I'm definitely going to have to dig into things a little deeper once I get the truck back. When I first got it, I spent my time fixing the minor mechanical issues it had. Replacing broken door handles, fixing inoperative windows, etc. Other than replacing the MAF Sensor, the truck was running...

    Front Diff and Suspension issues

    Thank you, that helps me feel better about it. Do most just use a disk grinder or have a machine shop do it?

    1999 K1500 w/ 3" lift. 35x12.5x20 Tires. Approx 310,000 miles. Bought the truck in late June. Sometime mid-July, the front differential started making a noise. I ended up taking it to a shop because I didn't have time to work on it due to other obligations. The shop found that a bearing in the...

    Front Axle issues

    I ended up taking to a friend's shop because I just have time to deal with it right now and I want it fixed. (Please don't revoke my man card! :) ) I work full time plus have a small farm... just not enough time in the day right now. They agreed that it probably tried to go into 4wd and didn't...
