eric.dally Posted March 3, 2011 Report Share Posted March 3, 2011 In the next month or so I am going to be pulling the transfer case off my truck to put my new torque convertor in and I've noticed the rear output shaft on the transfer case has started to get a little loose, maybe an 1/8 inch of play right now. Reading around I am assuming that the bore for the rear shaft bearing in the rear case half has more than likely become eggshaped and I will need a new rear case. Probably going to replace the chain while I am in there as well. Does anybody know of a place that sells reasonably priced transfer case parts for out cases? The only place I have found so far it was over $800 for the chain and case half. One thing though is they need to be new parts, I don't want to put used parts back on. Or if you have any ideas about how to fix this and prevent it from happening again please feel free to share them as well. And anybody that has done this before is there anything else that I should inspect or that needs to be replaced while it is apart? Oh yeah its an 03 with approx. 60,000 miles right now.

cadillacbob Posted March 6, 2011 Report Share Posted March 6, 2011 Anybody??? Someone's gotta know a decent place to buy transfer case parts? Finding the internals will be a p.i.t.a....at least that was my experience...it is a '149' case...and are getting hard to find...thank goodness that they are virtually indestructable... i ended up just 'rear halfing' my case (due to the pinhole leak issue), as the internals where like new...

BlownFogger540 Posted March 6, 2011 Report Share Posted March 6, 2011 (edited) the dealer is the only place for the nv149 parts the cases are magnesium strong but wear easy may be cheaper to have a machine shop bore and sleave it the bearing is not a press fit in the case, may also be the bearing alone thats the problem try these guys best prices ive seen on gm parts lower than gm parts direct and you can talk to these guys lol http://www.shopfbparts.com/servlet/StoreFront Edited March 8, 2011 by BlownFogger540 (see edit history) Quote Link to comment Share on other sites More sharing options...

Also was there supposed to be a link or something at the end of your post, you said "try these guys" but I don't see anyone listed?

misterp Posted March 8, 2011 Report Share Posted March 8, 2011 ...I've noticed the rear output shaft on the transfer case has started to get a little loose, maybe an 1/8 inch of play right now. ... An 1/8" is not merely 'a little play' - that's a ton of play (assuming you are talking about side-to-side or up-and-down play). Mr. P.

Mr. P. I may have been exageratting when I said an 1/8" I haven't actually measured it, but regardless there is a lot more radial play there than there should be and it needs to be fixed before it causes more issues. I'm one of those people that isn't going to wait around for it to break, I need to fix it as soon as I know something is wrong. Quote Link to comment Share on other sites More sharing options...
eric.dally Posted March 12, 2011 Author Report Share Posted March 12, 2011 Ok, new question...Is there a difference between the NV149 and NP149? I can find parts for the NP149, but is that the same as ours? I was pretty sure we had a NV149??? If they are different does anybody know if the chain or rear case would work from the NP149, from the pictures I can find of the NP149 online it looks about the same as mine.
