    99 Suburban Vibration

    Of course I don't know how long its been this way but I assume with it allowing "stuff" to get in there it probably has made the rear axle bearings shot? Would that also allow stuff to get into the rear diff or no? I guess to replace the axle bearings the rear diff has to get opened up anyways...

    99 Suburban Vibration

    I tried adjusting the hose clamps and didn't improve it any. Only made it worse or come back by moving them. Added a 3rd hose clamp and that made it worse too. I'm wondering if I got EXTREMELY lucky and placed them almost perfectly on my 2nd try? I also confirmed by a closer inspection that it...

    I'm not 100% sure if there was a weight there. It doesn't immediately appear like a spot where a weight was at first glance. If so I guess you were very much correct! :High 5:

    UPDATE: Tried the hose clamps on the driveshaft. 1st test seemed to make it worse. So I flipped it by 180 and added another hose clamp (because 1 didn't make a big difference). I noticed that the 180 spot I was tightening them down there was the sticker/label was for the drive shaft but it has...

    99 Suburban Vibration

    I have watched some videos on similar diagnostics I think. Using hose clamps or similar to add weights. I'll definitely have to try this out when I have time (probably this weekend). Although, would there be enough weights added to change the vibration enough to notice it while driving? I ask...

    No, should be oem size/ride height. aftermarket leaf springs (don't think you can even get GM genuine or if GM even makes the oem leaf springs anymore). They were as far as I know, same load rating, same amount of leaves, same shackle, bushings, and bolt sizes. I changed the leaf springs over 2...

    99 Suburban Vibration

    Frequency does seem to increase. Of course it gets harder to tell at higher speeds with air, engine, exhaust noise but frequency and intensity of vibration increases as speed increases. Tested the braking while maintaining speed and the noise and vibration did not noticeably change at all. I...

    Yeah the old set of leaf springs were sagging down quite a bit (especially after the towing/hauling I've done with it). Gained probably a good couple inches of clearance in the wheel hubs/wells. I'll check out the documentation you're referencing. I guess I was mainly wondering if the...

    Do you mean the U bolts on the axle that go over the leaf springs? Those are new with the leaf springs as well as the nuts. Visual inspection I didn't see any cracks in the leaf springs and seem to be tight (just by trying to shake/move them). Haven't gotten a socket/wrench on any of those...

    From what I saw and the dealership all the weights are still on the drive shaft.

    99 Suburban Vibration

    Hey, brand new to the forum and thus this is my first thread/post. So go easy on me ;) I have a 1999 Suburban K1500 5.7L V8 at ~168k miles. I'm currently chasing a vibration/rumble and I'm falling down the rabbit hole. I noticed a couple weeks ago (drive in to work was normal/good) that on my...
