Transfer case woes NP149

[01DenaliHiker]

So, I've finally accepted that I need to purchase a new transfer case. At least 1" of play all around from both shafts, hard acceleration produces the world's worst clunk on Earth followed by what sounds like grinding/clicking at first it seemed like the transmission mount, but that's nice and solid.

Previous owner apparently enjoyed running for however many miles without any fluid in it and I didn't discover it until after four months and about 5000 miles after the purchase. Just throws every drop out of the output seal.

Still runs and drives like a charm, just can't "get on it" without my truck sounding like it's about to turn inside out.

Any suggestions on a reputable place to order online? Only place that haunts my Google search is Monster Transmissions and Performance.

Got my front diff from them. No complaints

When I was looking for a replacement transmission I read about a lot of bad experiences with Monster so I ruled them out - FYI.

Do you know how to wrench or plan to remove it yourself? Just buy a new chain if it's AWD (BW4485)... You didn't specify what type of truck or T case you're talking about

I was kind of curious how long it would take to look in the forums... Fortunately, this OP doesn't have a high post count, so I found it easily, in one of his earlier posts. It's a 2001 Denali.

But, yeah, either having the vehicle in his tagline or being specific in his posting would make it MUCH easier to help him.

Depending on the transfer case, yes, a chain is all you need. Maybe a set of planetary gears if a tooth is broken. Since the OP didn't specify, I have no idea what T case he has. Most likely an older viscous coupling type. Still cheaper to rebuild it with $200 in parts vs $800-$1,400 for a reman unit

NP149, yes, viscous type coupler. Sorry, it took about four tries to actually post so I guess I left a lot out from #1 to the #4 successful try.

If they're not much to piece together what does everyone think about Rigid Axle's rebuild kit?

Does it sound like it's just a chain? I've stretched chains in a transfer once before on an old bog truck and didn't have the play I do currently from my shafts in this one.

I'm pretty savvy around tools, so I apologise ahead of time for sounding like a noob with no purpose here.

Only reason for worry is the way it seems to not stay stationary for lack of a better word. I bind like terrible at slow speeds at near full lock either way and under hard acceleration it literally feels like the transfer case is banging away, but if I grandma it right after it's just fine.

I thought I had u joint issues the way it would clunk into reverse and upon installing new ones realized my shafts wobbled inside the transfer case (can hear them knocking around) and leaked like a drunk after his thirty-third shot of patron with training wheels.

So with that information, willing to answer anything else if I possibly can; Does it sound like just a chain, or should I look into just doing a full overhaul and rebuilding it completely. I read something about the pump rubbing a hole into the rear case and highly doubt the previous owner did anything besides drive this like he stole it. No holes noticed, but just as a CYB (cover my butt) would a new rear portion be considered?

So many questions, I am a noob. No excuses after realizing what I'm typing here.
