Question about driveshaft balancing

I took the driveshaft to get balanced. I also had purchased some dc u-joints just in case, which he did replace. (He did not replace the others.) I did make sure he did dynamic balancing. He said the balancing was all good.
When I got it back I noticed the grease fittings were not lining up as though he had removed the axle pinion yoke flange. It was flipped. I normally might think it was my imagination. That maybe when I replaced the axle u-joint I had put it in with the fitting on the wrong side. However, & here’s where pics come in handy, I had recently taken some of the driveshaft.
I reinstalled it & the vibe is worse, so I crawled back under & found that he had done the same thing to the front (tc pinion).
My question you ask - is this part of driveshaft balancing? To remove the end yoke flanges? I called him this morning to ask about the phasing because I was confused & also asked him if he removed the flanges & he said no.
Anyway, now I’m pretty sure I have it phased incorrectly & need to flip the rear half.

Those new ujoints look sealed/not greasable. Hence, no grease zerk.

 

My bad. The fitting is now on the other side. I installed both a little while back. He only replaced the double cardan ones.
You see, in my 3rd pic above, both fittings are on the same side. Now they are not.


For this one, I had a red mark on one side & yellow on the other side. When I brought it in, the fitting was on the yellow side. Now it’s on the red marked side.

 

I had an 01 trd or. is the sr5 driveshaft 1 pc or 2.
It looks off side to side? loosen carrier bearing bolts and see if you can center it more.
Might cure the "worsened" vibe.

 

2 piece. It is off. I’ve tried that. The center bearing just goes back to where it wants to be. & I need to flip the rear 1/2 because I didn’t notice he flipped the front half yoke flange as well as the rear. You see he remarked everything on the rear half. My old markings were gone on it.

 

Carrier bearing can be put in upside down.
This video helped me straighten my vibes out.
Find a good bubble level app that reads angles. Fairly straight forward process.

Thank you.
I just don’t understand why he’d take those off & flip them & then say he didn’t. Not the end of the world. I’m just hoping he did everything else ok…. Just leaves ya wondering….

 

So what about just removing the driveshaft, rotating it 180° and reinstalling it? The phasing really only has those 2 options and then the zerk fittings would be back in the correct orientation (more or less). I'm with you thinking the driveshaft guy made a mistake, and is denying it.

 

This isn’t happening unless I undid the double cardan & flipped the end flanges. Basically the only fitting that is correctly orientated or in its original position is the slip yoke. & this I know is correct because there is a weight on the rear half of the shaft that is not showing in my pic from a while back. It’s on the other side of the shaft, hence not visible in the pic. Anyway, the weight still is not on the same side as the slip yoke fitting, so I can tell that at least that is lined up. Otherwise I’d be wondering about that as well.

In other words, all the u-joint fittings are facing the same way, only because he flipped the flanges. Which is maybe what happened. He screwed up the dc orientation, so covered his butt by flipping the tc & axle flanges. Course not much he could do about the slip yoke. He swore he gave it back to me the way I gave it to him. Didn’t count on me having pics though.
Ha-ha! Now I keep looking at it thinking I’m losing my marbles. Thank goodness I took those pics!

 

How exactly did he replace the double cardan u joints? Cut the double cardan out and weld a new one in?

Having been through this- you need to ensure the phasing is correct. You have aftermarket u joints in the front and back anyway, so using the zerk fittings on those as a reference in terms of phasing is irrelevant. So just worry about the flange orientation.

 

This is correct, phasing is just making sure that the drive shaft yokes are all in phase. The image posted by @ChargedSHOTaco is an excellent reference.

No. He swaps them out. He’s the driveshaft guy at a big rig repair shop. & obviously, he does smaller trucks as well.
& the fitting orientation is what threw me off because everything was all lined up. So it was relevant because that, plus my markings being gone, threw me off. I mean I get it that now it’s not relevant. I can phase, i guess it’s just going to be flipping the rear half. Pretty darned sure that slip yoke is in the correct way because I cannot see any weight on the tube in this pic & as it stands now, the weight is on the other side of the tube.

 

&, to add, as I asked in the beginning, I was curious if removing the flanges was part of balancing. Pretty sure it wasn’t, however maybe it was & he had misunderstood me when I called. He did seem to get it though. “Why would I do that?”

Anyway, I’m taking it it’s not part of balancing.

 

All that matters is the phase and balance at this point. It doesn't matter how it was before. Cause he would have taken it apart, done his work, balanced the shafts (either separately, or as one single unit) and installed it. As long as it's phased correctly, however it was before doesn't matter to how he balanced it.

 

Maybe I'm not following the terminology, but replacing u-joints means the flange becomes disconnected at that point

 

He had to remove them for the grease fittings to be 180deg opposite now. All of the grease fittings should be in a line like in the graphic pic. He may have thought of the grease fitting as a weight, but that’s just a guess. I’d rather tack a weight on instead of removing the u-joint any day.

Probably 75% of balancing the driveshaft is going to depend on the angles of your driveshaft when it is installed in your truck! You don’t seem to have an aftermarket lift or anything so there isn’t much that can change your drive shaft angles, other than worn engine and transmission mounts. Sagging rear spring’s can change the angles as well. It kinda needs to be on the truck to balance the driveshaft properly, using a vibration analyzer.

 

As others have stated, the grease zerks are irrelevant to actual phasing. The pic with them all lined up is just a reference. The only reason to remove the flanges would be to replace the u joints which it appears he did. As long as the ears the u joints are pressed in line up correctly the way the reference pic shows, then the phasing is good. Pretty sure the only way for the phasing to really be off is if the slip yolk was pulled off and not lines back up when re installed.

 

I am actually lifted about 1 1/2-2in. Started with coilovers & then I added a leaf.
Quick w/ my phone cuz I can’t find my angle thing
Tc case -4
Front half -6
Rear half -11
Axle pinion 7

 

He didn’t replace the flange end u-joints. They are still my old-ish ones. He Only relaxed the dc ones. That was my initial confusion. 1st, why remove the flanges…. 2nd, it threw me off because i had all the fittings lined up. When I got it back, they were not.
The weights matter, correct? I mean it can be phased two ways if the fittings are irrelevant. However, not the same with the weights…. Or are the irrelevant in respect to each other as well?
