Engine/Transmission (1998.5 - 2002) Does this look normal?

Also if the carrier went in without the help of a spreader then your bearings are gone, no preload on them.
For the preload you need a spreader.

For the backlash you need a backlash gauge, the FSM gives the numbers and how to use it.

I see and thank you for being willing to help and the info.

It wasn’t easy but it did go back in by hand.

So are you saying there’s no need to continue with these parts?

Edit: I don’t personally care about the noise, but I do care about it going bang and exiting parts out of the case or locking up a wheel. Is it safe to drive it if I work on it some more and it’s still noisy? Or no?

 

[Ozymandias]

If you don't care about the noise...

I would get new bearings and races for the pinion, breaking a driveshaft hits them badly.

Install according to the manual, use marking compound for the pattern and gauge for the back lash.

What isn't in the manuals.. after you installed the pinion, use a dead blow hammer and tap the pinion good from the inside of the case and from the outside onto the shafts end. This is to reassure that all bearings and races are fully set. It does not damage the bearings. Check rotating torque after this again to see if it changed.

You'll always have noise from the damaged pinion and gears, even the smallest imperfections on the teeth generate noise. Yours are badly beaten up.

But it won't explode because of this as long as the bearings work.
But you would want to check the internals regularly for excessive wear, also if the noise changes instantly.

Have you ever considered getting another axle form a scrap yard and just replace the whole thing?

 

[Ozymandias]

For the use of the spreader you need the backlash gauge also, it is a very small measured! amount that the case spreads and if you over do it it is thrash.
The FSM gives the value.

FSM for the truck or the axle? Thank you!

Yes, how bad of a job is that? I guess I would be worried about it being bad too, that would be more money sunk if so, and of course the weight of the assembly which I think is about 500 lbs. I’m also considering putting it on the hook and spending $16-$1800 I don’t have to have it redone by a local that is supposed to be really good with mechanicals

 

[petersonj]

Can you expound on phased drivetrain? Do you mean verification that each touched area is in the best known order?

A picture is worth a thousand words - a video, even more.

The last change at the end of the video relates to "phasing".

For the vehicle. You can buy one from Genos
Or Google it and find it online as a PDF.

He has a brand new one-piece driveshaft.
I'd be really worried if that came bad from the factory.

Change an axle isn't that bad of job, definitely easier then setting up a differential as it is a straight forward wrenching job.
If you can source one nearby with a return window in case of malfunctioning this would be great. The better sellers offer that.

I only posted the video because he asked about a "phased drivetrain".

Thank you for that, I will review it

I’m tempted. Thanks for all the input so far

If I overdo the spread I destroy the carrier housing?

Yes, it will be permanently stretched, that's why it is so important to follow the FSM for it.
Also the amount of spread gives the final pre load of the bearings.

Man y’all are good. Are y’all mechanics?

 

[Momilesmoproblems]

Just wanted to hopefully bring an end to this chapter. Had it put back RIGHT by someone who knows what they’re doing (to be honest, I am a mechanic but I don’t care to learn how to do this right since I’ll never have to do it again and it was noisy as all hell and I am OUT of patience.

A new r&p and it seems to be great on first impression. Thank you all so very much for all the insight and words and help.

 

[Ozymandias]

Glad to hear that you finally have it solved.
Anyway you learned a lot along the way to this.
